# JWT Authentication
## Description
A brief description of the jwt authentication project.
JWT (JSON Web Token) Authentication is a robust authentication method used for securely transmitting information between parties as a JSON object. This project demonstrates a simple implementation of JWT-based authentication in a web application. It ensures secure user authentication and authorization, allowing only authenticated users to access protected routes and resources.
## Features
- Feature 1
- Feature 2
- Feature 3
- **User Registration**: Allows new users to register by providing a username and password. The password is hashed for security.
- **User Login**: Authenticates users with their username and password. Upon successful authentication, a JWT is generated and returned.
- **Protected Routes**: Ensures that certain routes are accessible only to authenticated users by verifying the JWT.
## Technologies Used
- JavaScript
- HTML
- CSS
- **Node.js**: JavaScript runtime environment used to build the backend.
- **Express.js**: Web framework for Node.js used to build the API.
- **bcryptjs**: Library to hash passwords for secure storage.
- **jsonwebtoken**: Library to create and verify JWTs.
- **dotenv**: Module to load environment variables from a `.env` file.
## Setup
Instructions to set up and run the project.
Follow these instructions to set up and run the project:
1. **Clone the Repository**:
```sh
git clone https://github.com/deepakkumar55/ULTIMATE-JAVASCRIPT-PROJECT.git
cd Security\ Projects/1-jwt_authentication
```
2. **Install Dependencies**:
Ensure you have Node.js and npm installed. Then run:
```sh
npm install
```
3. **Set Up Environment Variables**:
Create a `.env` file in the root directory and add the following environment variables:
```
PORT=3000
JWT_SECRET=your_jwt_secret
```
4. **Run the Server**:
Start the server using:
```sh
npm start
```
5. **Access the Application**:
Open your browser and navigate to `http://localhost:3000` to access the application.
### Final Steps
1. **Run the Server**: Use the following command to start the server:
```sh
npm start
```
2. **Test the Endpoints**:
- **Register a User**: Send a POST request to `http://localhost:3000/auth/register` with a JSON body containing `username` and `password`.
- **Login a User**: Send a POST request to `http://localhost:3000/auth/login` with a JSON body containing `username` and `password`. You'll receive a JWT token if the credentials are valid.
- **Access Protected Route**: Send a GET request to `http://localhost:3000/auth/protected` with an `Authorization` header containing `Bearer <your_jwt_token>`.

# accepts
[![NPM Version][npm-version-image]][npm-url]
[![NPM Downloads][npm-downloads-image]][npm-url]

Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
In addition to negotiator, it allows:
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install accepts
```
## API
```js
var accepts = require('accepts')
```
### accepts(req)
Create a new `Accepts` object for the given `req`.
#### .charset(charsets)
Return the first accepted charset. If nothing in `charsets` is accepted,
then `false` is returned.
#### .charsets()
Return the charsets that the request accepts, in the order of the client's
preference (most preferred first).
#### .encoding(encodings)
Return the first accepted encoding. If nothing in `encodings` is accepted,
then `false` is returned.
#### .encodings()
Return the encodings that the request accepts, in the order of the client's
preference (most preferred first).
#### .language(languages)
Return the first accepted language. If nothing in `languages` is accepted,
then `false` is returned.
#### .languages()
Return the languages that the request accepts, in the order of the client's
preference (most preferred first).
#### .type(types)
Return the first accepted type (and it is returned as the same text as what
appears in the `types` array). If nothing in `types` is accepted, then `false`
is returned.
The `types` array can contain full MIME types or file extensions. Any value
that is not a full MIME types is passed to `require('mime-types').lookup`.
#### .types()
Return the types that the request accepts, in the order of the client's
preference (most preferred first).
## Examples
### Simple type negotiation
This simple example shows how to use `accepts` to return a different typed
respond body based on what the client wants to accept. The server lists it's
preferences in order and will get back the best match between the client and
server.
```js
var accepts = require('accepts')
var http = require('http')
function app (req, res) {
var accept = accepts(req)
// the order of this list is significant; should be server preferred order
switch (accept.type(['json', 'html'])) {
case 'json':
res.setHeader('Content-Type', 'application/json')
res.write('{"hello":"world!"}')
break
case 'html':
res.setHeader('Content-Type', 'text/html')
res.write('<b>hello, world!</b>')
break
default:
// the fallback is text/plain, so no need to specify it above
res.setHeader('Content-Type', 'text/plain')
res.write('hello, world!')
break
}
res.end()
}
http.createServer(app).listen(3000)
```
You can test this out with the cURL program:
```sh
curl -I -H'Accept: text/html' http://localhost:3000/
```

bcrypt.js
=========
Optimized bcrypt in JavaScript with zero dependencies. Compatible to the C++ [bcrypt](https://npmjs.org/package/bcrypt)
binding on node.js and also working in the browser.
<a href="https://travis-ci.org/dcodeIO/bcrypt.js"><img alt="build static" src="https://travis-ci.org/dcodeIO/bcrypt.js.svg?branch=master" /></a> <a href="https://npmjs.org/package/bcryptjs"><img src="https://img.shields.io/npm/v/bcryptjs.svg" alt=""></a> <a href="https://npmjs.org/package/bcryptjs"><img src="https://img.shields.io/npm/dm/bcryptjs.svg" alt=""></a> <a href="https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=dcode%40dcode.io&item_name=Open%20Source%20Software%20Donation&item_number=dcodeIO%2Fbcrypt.js"><img alt="donate ❤" src="https://img.shields.io/badge/donate-❤-ff2244.svg"></a>
Security considerations
-----------------------
Besides incorporating a salt to protect against rainbow table attacks, bcrypt is an adaptive function: over time, the
iteration count can be increased to make it slower, so it remains resistant to brute-force search attacks even with
increasing computation power. ([see](http://en.wikipedia.org/wiki/Bcrypt))
While bcrypt.js is compatible to the C++ bcrypt binding, it is written in pure JavaScript and thus slower ([about 30%](https://github.com/dcodeIO/bcrypt.js/wiki/Benchmark)), effectively reducing the number of iterations that can be
processed in an equal time span.
The maximum input length is 72 bytes (note that UTF8 encoded characters use up to 4 bytes) and the length of generated
hashes is 60 characters.
Usage
-----
The library is compatible with CommonJS and AMD loaders and is exposed globally as `dcodeIO.bcrypt` if neither is
available.
### node.js
On node.js, the inbuilt [crypto module](http://nodejs.org/api/crypto.html)'s randomBytes interface is used to obtain
secure random numbers.
`npm install bcryptjs`
```js
var bcrypt = require('bcryptjs');
...
```
### Browser
In the browser, bcrypt.js relies on [Web Crypto API](http://www.w3.org/TR/WebCryptoAPI)'s getRandomValues
interface to obtain secure random numbers. If no cryptographically secure source of randomness is available, you may
specify one through [bcrypt.setRandomFallback](https://github.com/dcodeIO/bcrypt.js#setrandomfallbackrandom).
```js
var bcrypt = dcodeIO.bcrypt;
...
```
or
```js
require.config({
paths: { "bcrypt": "/path/to/bcrypt.js" }
});
require(["bcrypt"], function(bcrypt) {
...
});
```
Usage - Sync
------------
To hash a password:
```javascript
var bcrypt = require('bcryptjs');
var salt = bcrypt.genSaltSync(10);
var hash = bcrypt.hashSync("B4c0/\/", salt);
// Store hash in your password DB.
```
To check a password:
```javascript
// Load hash from your password DB.
bcrypt.compareSync("B4c0/\/", hash); // true
bcrypt.compareSync("not_bacon", hash); // false
```
Auto-gen a salt and hash:
```javascript
var hash = bcrypt.hashSync('bacon', 8);
```
Usage - Async
-------------
To hash a password:
```javascript
var bcrypt = require('bcryptjs');
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash("B4c0/\/", salt, function(err, hash) {
// Store hash in your password DB.
});
});
```
To check a password:
```javascript
// Load hash from your password DB.
bcrypt.compare("B4c0/\/", hash, function(err, res) {
// res === true
});
bcrypt.compare("not_bacon", hash, function(err, res) {
// res === false
});
// As of bcryptjs 2.4.0, compare returns a promise if callback is omitted:
bcrypt.compare("B4c0/\/", hash).then((res) => {
// res === true
});
```
Auto-gen a salt and hash:
```javascript
bcrypt.hash('bacon', 8, function(err, hash) {
});
```
**Note:** Under the hood, asynchronisation splits a crypto operation into small chunks. After the completion of a chunk, the execution of the next chunk is placed on the back of [JS event loop queue](https://developer.mozilla.org/en/docs/Web/JavaScript/EventLoop), thus efficiently sharing the computational resources with the other operations in the queue.
API
---
### setRandomFallback(random)
Sets the pseudo random number generator to use as a fallback if neither node's `crypto` module nor the Web Crypto
API is available. Please note: It is highly important that the PRNG used is cryptographically secure and that it is
seeded properly!
| Parameter | Type | Description
|-----------------|-----------------|---------------
| random | *function(number):!Array.&lt;number&gt;* | Function taking the number of bytes to generate as its sole argument, returning the corresponding array of cryptographically secure random byte values.
| **@see** | | http://nodejs.org/api/crypto.html
| **@see** | | http://www.w3.org/TR/WebCryptoAPI/
**Hint:** You might use [isaac.js](https://github.com/rubycon/isaac.js) as a CSPRNG but you still have to make sure to
seed it properly.
### genSaltSync(rounds=, seed_length=)
Synchronously generates a salt.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| rounds | *number* | Number of rounds to use, defaults to 10 if omitted
| seed_length | *number* | Not supported.
| **@returns** | *string* | Resulting salt
| **@throws** | *Error* | If a random fallback is required but not set
### genSalt(rounds=, seed_length=, callback)

| seed_length | *number &#124; function(Error, string=)* | Not supported.
| callback | *function(Error, string=)* | Callback receiving the error, if any, and the resulting salt
| **@returns** | *Promise* | If `callback` has been omitted
| **@throws** | *Error* | If `callback` is present but not a function
### hashSync(s, salt=)
Synchronously generates a hash for the given string.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| s | *string* | String to hash
| salt | *number &#124; string* | Salt length to generate or salt to use, default to 10
| **@returns** | *string* | Resulting hash
### hash(s, salt, callback, progressCallback=)
Asynchronously generates a hash for the given string.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| s | *string* | String to hash
| salt | *number &#124; string* | Salt length to generate or salt to use
| callback | *function(Error, string=)* | Callback receiving the error, if any, and the resulting hash
| progressCallback | *function(number)* | Callback successively called with the percentage of rounds completed (0.0 - 1.0), maximally once per `MAX_EXECUTION_TIME = 100` ms.
| **@returns** | *Promise* | If `callback` has been omitted
| **@throws** | *Error* | If `callback` is present but not a function
### compareSync(s, hash)
Synchronously tests a string against a hash.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| s | *string* | String to compare
| hash | *string* | Hash to test against
| **@returns** | *boolean* | true if matching, otherwise false
| **@throws** | *Error* | If an argument is illegal
### compare(s, hash, callback, progressCallback=)
Asynchronously compares the given data against the given hash.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| s | *string* | Data to compare
| hash | *string* | Data to be compared to
| callback | *function(Error, boolean)* | Callback receiving the error, if any, otherwise the result
| progressCallback | *function(number)* | Callback successively called with the percentage of rounds completed (0.0 - 1.0), maximally once per `MAX_EXECUTION_TIME = 100` ms.
| **@returns** | *Promise* | If `callback` has been omitted
| **@throws** | *Error* | If `callback` is present but not a function
### getRounds(hash)
Gets the number of rounds used to encrypt the specified hash.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| hash | *string* | Hash to extract the used number of rounds from
| **@returns** | *number* | Number of rounds used
| **@throws** | *Error* | If `hash` is not a string
### getSalt(hash)
Gets the salt portion from a hash. Does not validate the hash.
| Parameter | Type | Description
|-----------------|-----------------|---------------
| hash | *string* | Hash to extract the salt from
| **@returns** | *string* | Extracted salt part
| **@throws** | *Error* | If `hash` is not a string or otherwise invalid

Because of [reasonable security doubts](https://github.com/dcodeIO/bcrypt.js/issues/16), these files, which used to be
a part of bcrypt-isaac.js, are no longer used but are kept here for reference only.
What is required instead is a proper way to collect entropy sources (using an intermediate stream cipher) which is then
used to seed the CSPRNG. Pick one and use `bcrypt.setRandomFallback` instead.

Node.js body parsing middleware.
Parse incoming request bodies in a middleware before your handlers, available
under the `req.body` property.
**Note** As `req.body`'s shape is based on user-controlled input, all
properties and values in this object are untrusted and should be validated
before trusting. For example, `req.body.foo.toString()` may fail in multiple
ways, for example the `foo` property may not be there or may not be a string,
and `toString` may not be a function and instead a string or other user input.
[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
_This does not handle multipart bodies_, due to their complex and typically
large nature. For multipart bodies, you may be interested in the following
modules:
* [busboy](https://www.npmjs.org/package/busboy#readme) and
[connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
* [multiparty](https://www.npmjs.org/package/multiparty#readme) and
[connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
* [formidable](https://www.npmjs.org/package/formidable#readme)
* [multer](https://www.npmjs.org/package/multer#readme)
This module provides the following parsers:
* [JSON body parser](#bodyparserjsonoptions)
* [Raw body parser](#bodyparserrawoptions)
* [Text body parser](#bodyparsertextoptions)
* [URL-encoded form body parser](#bodyparserurlencodedoptions)
Other body parsers you might be interested in:
- [body](https://www.npmjs.org/package/body#readme)
- [co-body](https://www.npmjs.org/package/co-body#readme)
## Installation
```sh
$ npm install body-parser
```
## API
```js
var bodyParser = require('body-parser')
```
The `bodyParser` object exposes various factories to create middlewares. All
middlewares will populate the `req.body` property with the parsed body when
the `Content-Type` request header matches the `type` option, or an empty
object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
or an error occurred.
The various errors returned by this module are described in the
[errors section](#errors).
### bodyParser.json([options])
Returns middleware that only parses `json` and only looks at requests where
the `Content-Type` header matches the `type` option. This parser accepts any
Unicode encoding of the body and supports automatic inflation of `gzip` and
`deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`).
#### Options
The `json` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### reviver
The `reviver` option is passed directly to `JSON.parse` as the second
argument. You can find more information on this argument
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
##### strict
When set to `true`, will only accept arrays and objects; when `false` will
accept anything `JSON.parse` accepts. Defaults to `true`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not a
function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `json`), a mime type (like `application/json`), or
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a truthy
value. Defaults to `application/json`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.raw([options])
Returns middleware that parses all bodies as a `Buffer` and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a `Buffer` object
of the body.
#### Options
The `raw` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function.
If not a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this
can be an extension name (like `bin`), a mime type (like
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
`application/*`). If a function, the `type` option is called as `fn(req)`
and the request is parsed if it returns a truthy value. Defaults to
`application/octet-stream`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.text([options])
Returns middleware that parses all bodies as a string and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` string containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a string of the
body.
#### Options
The `text` function takes an optional `options` object that may contain any of
the following keys:
##### defaultCharset
Specify the default character set for the text content if the charset is not
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a
truthy value. Defaults to `text/plain`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.urlencoded([options])
Returns middleware that only parses `urlencoded` bodies and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser accepts only UTF-8 encoding of the body and supports automatic
inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This object will contain
key-value pairs, where the value can be a string or array (when `extended` is
`false`), or any type (when `extended` is `true`).
#### Options
The `urlencoded` function takes an optional `options` object that may contain
any of the following keys:
##### extended
The `extended` option allows to choose between parsing the URL-encoded data
with the `querystring` library (when `false`) or the `qs` library (when
`true`). The "extended" syntax allows for rich objects and arrays to be
encoded into the URL-encoded format, allowing for a JSON-like experience
with URL-encoded. For more information, please
[see the qs library](https://www.npmjs.org/package/qs#readme).
Defaults to `true`, but using the default has been deprecated. Please
research into the difference between `qs` and `querystring` and choose the
appropriate setting.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### parameterLimit
The `parameterLimit` option controls the maximum number of parameters that
are allowed in the URL-encoded data. If a request contains more parameters
than this value, a 413 will be returned to the client. Defaults to `1000`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `urlencoded`), a mime type (like
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
`*/x-www-form-urlencoded`). If a function, the `type` option is called as
`fn(req)` and the request is parsed if it returns a truthy value. Defaults
to `application/x-www-form-urlencoded`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
## Errors
The middlewares provided by this module create errors using the
[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
will typically have a `status`/`statusCode` property that contains the suggested
HTTP response code, an `expose` property to determine if the `message` property
should be displayed to the client, a `type` property to determine the type of
error without matching against the `message`, and a `body` property containing
the read body, if available.
The following are the common errors created, though any error can come through
for various reasons.
### content encoding unsupported
This error will occur when the request had a `Content-Encoding` header that
contained an encoding but the "inflation" option was set to `false`. The
`status` property is set to `415`, the `type` property is set to
`'encoding.unsupported'`, and the `charset` property will be set to the
encoding that is unsupported.
### entity parse failed
This error will occur when the request contained an entity that could not be
parsed by the middleware. The `status` property is set to `400`, the `type`
property is set to `'entity.parse.failed'`, and the `body` property is set to
the entity value that failed parsing.
### entity verify failed
This error will occur when the request contained an entity that could not be
failed verification by the defined `verify` option. The `status` property is
set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
`body` property is set to the entity value that failed verification.
### request aborted
This error will occur when the request is aborted by the client before reading
the body has finished. The `received` property will be set to the number of
bytes received before the request was aborted and the `expected` property is
set to the number of expected bytes. The `status` property is set to `400`
and `type` property is set to `'request.aborted'`.
### request entity too large
This error will occur when the request body's size is larger than the "limit"
option. The `limit` property will be set to the byte limit and the `length`
property will be set to the request body's length. The `status` property is
set to `413` and the `type` property is set to `'entity.too.large'`.
### request size did not match content length
This error will occur when the request's length did not match the length from
the `Content-Length` header. This typically occurs when the request is malformed,
typically when the `Content-Length` header was calculated based on characters
instead of bytes. The `status` property is set to `400` and the `type` property
is set to `'request.size.invalid'`.
### stream encoding should not be set
This error will occur when something called the `req.setEncoding` method prior
to this middleware. This module operates directly on bytes only and you cannot
call `req.setEncoding` when using this module. The `status` property is set to
`500` and the `type` property is set to `'stream.encoding.set'`.
### stream is not readable
This error will occur when the request is no longer readable when this middleware
attempts to read it. This typically means something other than a middleware from
this module read the request body already and the middleware was also configured to
read the same request. The `status` property is set to `500` and the `type`
property is set to `'stream.not.readable'`.
### too many parameters
This error will occur when the content of the request exceeds the configured
`parameterLimit` for the `urlencoded` parser. The `status` property is set to
`413` and the `type` property is set to `'parameters.too.many'`.
### unsupported charset "BOGUS"
This error will occur when the request had a charset parameter in the
`Content-Type` header, but the `iconv-lite` module does not support it OR the
parser does not support it. The charset is contained in the message as well
as in the `charset` property. The `status` property is set to `415`, the
`type` property is set to `'charset.unsupported'`, and the `charset` property
is set to the charset that is unsupported.
### unsupported content encoding "bogus"
This error will occur when the request had a `Content-Encoding` header that
contained an unsupported encoding. The encoding is contained in the message
as well as in the `encoding` property. The `status` property is set to `415`,
the `type` property is set to `'encoding.unsupported'`, and the `encoding`
property is set to the encoding that is unsupported.
## Examples
### Express/Connect top-level generic
This example demonstrates adding a generic JSON and URL-encoded parser as a
top-level middleware, which will parse the bodies of all incoming requests.
This is the simplest setup.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain')
res.write('you posted:\n')
res.end(JSON.stringify(req.body, null, 2))
})
```
### Express route-specific
This example demonstrates adding body parsers specifically to the routes that
need them. In general, this is the most recommended way to use body-parser with
Express.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// create application/json parser
var jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
res.send('welcome, ' + req.body.username)
})
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
// create user in req.body
})
```
### Change accepted type for parsers
All the parsers accept a `type` option which allows you to change the
`Content-Type` that the middleware will parse.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse various different custom JSON types as JSON
app.use(bodyParser.json({ type: 'application/*+json' }))
// parse some custom thing into a Buffer
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
// parse an HTML body into a string
app.use(bodyParser.text({ type: 'text/html' }))
```

# buffer-equal-constant-time
Constant-time `Buffer` comparison for node.js. Should work with browserify too.
[![Build Status](https://travis-ci.org/goinstant/buffer-equal-constant-time.png?branch=master)](https://travis-ci.org/goinstant/buffer-equal-constant-time)
```sh
npm install buffer-equal-constant-time
```
# Usage
```js
var bufferEq = require('buffer-equal-constant-time');
var a = new Buffer('asdf');
var b = new Buffer('asdf');
if (bufferEq(a,b)) {
// the same!
} else {
// different in at least one byte!
}
```
If you'd like to install an `.equal()` method onto the node.js `Buffer` and
`SlowBuffer` prototypes:
```js
require('buffer-equal-constant-time').install();
var a = new Buffer('asdf');
var b = new Buffer('asdf');
if (a.equal(b)) {
// the same!
} else {
// different in at least one byte!
}
```
To get rid of the installed `.equal()` method, call `.restore()`:
```js
require('buffer-equal-constant-time').restore();
```

# Bytes utility
[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
[![Build Status][ci-image]][ci-url]
[![Test Coverage][coveralls-image]][coveralls-url]
Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```bash
$ npm install bytes
```
## Usage
```js
var bytes = require('bytes');
```
#### bytes(numberstring value, [options]): numberstringnull
Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number``string` | Number value to format or string value to parse |
| options | `Object` | Conversion options for `format` |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string``number``null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
**Example**
```js
bytes(1024);
// output: '1KB'
bytes('1KB');
// output: 1024
```
#### bytes.format(number value, [options]): stringnull
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
rounded.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number` | Value in bytes |
| options | `Object` | Conversion options |
**Options**
| Property | Type | Description |
|-------------------|--------|-----------------------------------------------------------------------------------------|
| decimalPlaces | `number``null` | Maximum number of decimal places to include in output. Default value to `2`. |
| fixedDecimals | `boolean``null` | Whether to always display the maximum number of decimal places. Default value to `false` |
| thousandsSeparator | `string``null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
| unit | `string``null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
| unitSeparator | `string``null` | Separator to use between number and unit. Default value to `''`. |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string``null` | Return null upon error. String value otherwise. |
**Example**
```js
bytes.format(1024);
// output: '1KB'
bytes.format(1000);
// output: '1000B'
bytes.format(1000, {thousandsSeparator: ' '});
// output: '1 000B'
bytes.format(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'
bytes.format(1024, {unitSeparator: ' '});
// output: '1 KB'
```
#### bytes.parse(stringnumber value): numbernull
Parse the string value into an integer in bytes. If no unit is given, or `value`
is a number, it is assumed the value is in bytes.
Supported units and abbreviations are as follows and are case-insensitive:
* `b` for bytes
* `kb` for kilobytes
* `mb` for megabytes
* `gb` for gigabytes
* `tb` for terabytes
* `pb` for petabytes
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
**Arguments**
| Name | Type | Description |
|---------------|--------|--------------------|
| value | `string``number` | String to parse, or number in bytes. |
**Returns**
| Name | Type | Description |
|---------|-------------|-------------------------|
| results | `number``null` | Return null upon error. Value in bytes otherwise. |
**Example**
```js
bytes.parse('1KB');
// output: 1024
bytes.parse('1024');
// output: 1024
bytes.parse(1024);
// output: 1024

Robustly `.call.bind()` a function.
## Getting started
```sh
npm install --save call-bind
```
## Usage/Examples
```js
const assert = require('assert');
const callBind = require('call-bind');
const callBound = require('call-bind/callBound');
function f(a, b) {
assert.equal(this, 1);
assert.equal(a, 2);
assert.equal(b, 3);
assert.equal(arguments.length, 2);
}
const fBound = callBind(f);
const slice = callBound('Array.prototype.slice');
delete Function.prototype.call;
delete Function.prototype.bind;
fBound(1, 2, 3);
assert.deepEqual(slice([1, 2, 3, 4], 1, -1), [2, 3]);
```
## Tests
Clone the repo, `npm install`, and run `npm test`

Create and parse HTTP `Content-Disposition` header
## Installation
```sh
$ npm install content-disposition
```
## API
```js
var contentDisposition = require('content-disposition')
```
### contentDisposition(filename, options)
Create an attachment `Content-Disposition` header value using the given file name,
if supplied. The `filename` is optional and if no file name is desired, but you
want to specify `options`, set `filename` to `undefined`.
```js
res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
```
**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
header through a means different from `setHeader` in Node.js, you'll want to specify
the `'binary'` encoding in Node.js.
#### Options
`contentDisposition` accepts these properties in the options object.
##### fallback
If the `filename` option is outside ISO-8859-1, then the file name is actually
stored in a supplemental field for clients that support Unicode file names and
a ISO-8859-1 version of the file name is automatically generated.
This specifies the ISO-8859-1 file name to override the automatic generation or
disables the generation all together, defaults to `true`.
- A string will specify the ISO-8859-1 file name to use in place of automatic
generation.
- `false` will disable including a ISO-8859-1 file name and only include the
Unicode version (unless the file name is already ISO-8859-1).
- `true` will enable automatic generation if the file name is outside ISO-8859-1.
If the `filename` option is ISO-8859-1 and this option is specified and has a
different value, then the `filename` option is encoded in the extended field
and this set as the fallback field, even though they are both ISO-8859-1.
##### type
Specifies the disposition type, defaults to `"attachment"`. This can also be
`"inline"`, or any other value (all values except inline are treated like
`attachment`, but can convey additional information if both parties agree to
it). The type is normalized to lower-case.
### contentDisposition.parse(string)
```js
var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
```
Parse a `Content-Disposition` header string. This automatically handles extended
("Unicode") parameters by decoding them and providing them under the standard
parameter name. This will return an object with the following properties (examples
are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
- `type`: The disposition type (always lower case). Example: `'attachment'`
- `parameters`: An object of the parameters in the disposition (name of parameter
always lower case and extended versions replace non-extended versions). Example:
`{filename: "€ rates.txt"}`
## Examples
### Send a file for download
```js
var contentDisposition = require('content-disposition')
var destroy = require('destroy')
var fs = require('fs')
var http = require('http')
var onFinished = require('on-finished')
var filePath = '/path/to/public/plans.pdf'
http.createServer(function onRequest (req, res) {
// set headers
res.setHeader('Content-Type', 'application/pdf')
res.setHeader('Content-Disposition', contentDisposition(filePath))
// send file
var stream = fs.createReadStream(filePath)
stream.pipe(res)
onFinished(res, function () {
destroy(stream)
})
})
```
## Testing
```sh
$ npm test
```

Create and parse HTTP Content-Type header according to RFC 7231
## Installation
```sh
$ npm install content-type
```
## API
```js
var contentType = require('content-type')
```
### contentType.parse(string)
```js
var obj = contentType.parse('image/svg+xml; charset=utf-8')
```
Parse a `Content-Type` header. This will return an object with the following
properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (the type and subtype, always lower case).
Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of parameter
always lower case). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the string is missing or invalid.
### contentType.parse(req)
```js
var obj = contentType.parse(req)
```
Parse the `Content-Type` header from the given `req`. Short-cut for
`contentType.parse(req.headers['content-type'])`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.parse(res)
```js
var obj = contentType.parse(res)
```
Parse the `Content-Type` header set on the given `res`. Short-cut for
`contentType.parse(res.getHeader('content-type'))`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.format(obj)
```js
var str = contentType.format({
type: 'image/svg+xml',
parameters: { charset: 'utf-8' }
})
```
Format an object into a `Content-Type` header. This will return a string of the
content type for the given object with the following properties (examples are
shown that produce the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of the
parameter will be lower-cased). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the object contains an invalid type or parameter names.

# cookie
[![NPM Version][npm-version-image]][npm-url]
[![NPM Downloads][npm-downloads-image]][npm-url]
[![Node.js Version][node-image]][node-url]
[![Build Status][ci-image]][ci-url]
[![Coverage Status][coveralls-image]][coveralls-url]
Basic HTTP cookie parser and serializer for HTTP servers.
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install cookie
```
## API
```js
var cookie = require('cookie');
```
### cookie.parse(str, options)
Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
The `str` argument is the string representing a `Cookie` header value and `options` is an
optional object containing additional parsing options.
```js
var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
// { foo: 'bar', equation: 'E=mc^2' }
```
#### Options
`cookie.parse` accepts these properties in the options object.
##### decode
Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
has a limited character set (and must be a simple string), this function can be used to decode
a previously-encoded cookie value into a JavaScript string or other object.
The default function is the global `decodeURIComponent`, which will decode any URL-encoded
sequences into their byte representations.
**note** if an error is thrown from this function, the original, non-decoded cookie value will
be returned as the cookie's value.
### cookie.serialize(name, value, options)
Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
argument is an optional object containing additional serialization options.
```js
var setCookie = cookie.serialize('foo', 'bar');
// foo=bar
```
#### Options
`cookie.serialize` accepts these properties in the options object.
##### domain
Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
domain is set, and most clients will consider the cookie to apply to only the current domain.
##### encode
Specifies a function that will be used to encode a cookie's value. Since value of a cookie
has a limited character set (and must be a simple string), this function can be used to encode
a value into a string suited for a cookie's value.
The default function is the global `encodeURIComponent`, which will encode a JavaScript string
into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
##### expires
Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
will delete it on a condition like exiting a web browser application.
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
so if both are set, they should point to the same date and time.
##### httpOnly
Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
**note** be careful when setting this to `true`, as compliant clients will not allow client-side
JavaScript to see the cookie in `document.cookie`.
##### maxAge
Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
The given number will be converted to an integer by rounding down. By default, no maximum age is set.
**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
so if both are set, they should point to the same date and time.
##### partitioned
Specifies the `boolean` value for the [`Partitioned` `Set-Cookie`](rfc-cutler-httpbis-partitioned-cookies)
attribute. When truthy, the `Partitioned` attribute is set, otherwise it is not. By default, the
`Partitioned` attribute is not set.
**note** This is an attribute that has not yet been fully standardized, and may change in the future.
This also means many clients may ignore this attribute until they understand it.
More information about can be found in [the proposal](https://github.com/privacycg/CHIPS).
##### path
Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
is considered the ["default path"][rfc-6265-5.1.4].
##### priority
Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1].
- `'low'` will set the `Priority` attribute to `Low`.
- `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
- `'high'` will set the `Priority` attribute to `High`.
More information about the different priority levels can be found in
[the specification][rfc-west-cookie-priority-00-4.1].
**note** This is an attribute that has not yet been fully standardized, and may change in the future.
This also means many clients may ignore this attribute until they understand it.
##### sameSite
Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7].
- `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
- `false` will not set the `SameSite` attribute.
- `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
- `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
- `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
More information about the different enforcement levels can be found in
[the specification][rfc-6265bis-09-5.4.7].
**note** This is an attribute that has not yet been fully standardized, and may change in the future.
This also means many clients may ignore this attribute until they understand it.
##### secure
Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
the server in the future if the browser does not have an HTTPS connection.
## Example
The following example uses this module in conjunction with the Node.js core HTTP server
to prompt a user for their name and display it back on future visits.
```js
var cookie = require('cookie');
var escapeHtml = require('escape-html');
var http = require('http');
var url = require('url');
function onRequest(req, res) {
// Parse the query string
var query = url.parse(req.url, true, true).query;
if (query && query.name) {
// Set a new cookie with the name
res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
httpOnly: true,
maxAge: 60 * 60 * 24 * 7 // 1 week
}));
// Redirect back after setting cookie
res.statusCode = 302;
res.setHeader('Location', req.headers.referer || '/');
res.end();
return;
}
// Parse the cookies on the request
var cookies = cookie.parse(req.headers.cookie || '');
// Get the visitor name set in the cookie
var name = cookies.name;
res.setHeader('Content-Type', 'text/html; charset=UTF-8');
if (name) {
res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
} else {
res.write('<p>Hello, new visitor!</p>');
}
res.write('<form method="GET">');
res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
res.end('</form>');
}
http.createServer(onRequest).listen(3000);

The `cookie` team and community take all security bugs seriously. Thank
you for improving the security of the project. We appreciate your efforts and
responsible disclosure and will make every effort to acknowledge your
contributions.
Report security bugs by emailing the current owner(s) of `cookie`. This
information can be found in the npm registry using the command
`npm owner ls cookie`.
If unsure or unable to get the information from the above, open an issue
in the [project issue tracker](https://github.com/jshttp/cookie/issues)
asking for the current contact information.
To ensure the timely response to your report, please ensure that the entirety
of the report is contained within the email body and not solely behind a web
link or an attachment.
At least one owner will acknowledge your email within 48 hours, and will send a
more detailed response within 48 hours indicating the next steps in handling
your report. After the initial reply to your report, the owners will
endeavor to keep you informed of the progress towards a fix and full
announcement, and may ask for additional information or guidance.
