## 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 cors
```
## Usage
### Simple Usage (Enable *All* CORS Requests)
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.get('/products/:id', function (req, res, next) {
res.json({msg: 'This is CORS-enabled for all origins!'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
### Enable CORS for a Single Route
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
app.get('/products/:id', cors(), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for a Single Route'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
### Configuring CORS
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
var corsOptions = {
origin: 'http://example.com',
optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204
}
app.get('/products/:id', cors(corsOptions), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for only example.com.'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
### Configuring CORS w/ Dynamic Origin
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
var whitelist = ['http://example1.com', 'http://example2.com']
var corsOptions = {
origin: function (origin, callback) {
if (whitelist.indexOf(origin) !== -1) {
callback(null, true)
} else {
callback(new Error('Not allowed by CORS'))
}
}
}
app.get('/products/:id', cors(corsOptions), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
If you do not want to block REST tools or server-to-server requests,
add a `!origin` check in the origin function like so:
```javascript
var corsOptions = {
origin: function (origin, callback) {
if (whitelist.indexOf(origin) !== -1 || !origin) {
callback(null, true)
} else {
callback(new Error('Not allowed by CORS'))
}
}
}
```
### Enabling CORS Pre-Flight
Certain CORS requests are considered 'complex' and require an initial
`OPTIONS` request (called the "pre-flight request"). An example of a
'complex' CORS request is one that uses an HTTP verb other than
GET/HEAD/POST (such as DELETE) or that uses custom headers. To enable
pre-flighting, you must add a new OPTIONS handler for the route you want
to support:
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
app.options('/products/:id', cors()) // enable pre-flight request for DELETE request
app.del('/products/:id', cors(), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for all origins!'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
You can also enable pre-flight across-the-board like so:
```javascript
app.options('*', cors()) // include before other routes
```
### Configuring CORS Asynchronously
```javascript
var express = require('express')
var cors = require('cors')
var app = express()
var whitelist = ['http://example1.com', 'http://example2.com']
var corsOptionsDelegate = function (req, callback) {
var corsOptions;
if (whitelist.indexOf(req.header('Origin')) !== -1) {
corsOptions = { origin: true } // reflect (enable) the requested origin in the CORS response
} else {
corsOptions = { origin: false } // disable CORS for this request
}
callback(null, corsOptions) // callback expects two parameters: error and options
}
app.get('/products/:id', cors(corsOptionsDelegate), function (req, res, next) {
res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
})
app.listen(80, function () {
console.log('CORS-enabled web server listening on port 80')
})
```
## Configuration Options
* `origin`: Configures the **Access-Control-Allow-Origin** CORS header. Possible values:
- `Boolean` - set `origin` to `true` to reflect the [request origin](http://tools.ietf.org/html/draft-abarth-origin-09), as defined by `req.header('Origin')`, or set it to `false` to disable CORS.
- `String` - set `origin` to a specific origin. For example if you set it to `"http://example.com"` only requests from "http://example.com" will be allowed.
- `RegExp` - set `origin` to a regular expression pattern which will be used to test the request origin. If it's a match, the request origin will be reflected. For example the pattern `/example\.com$/` will reflect any request that is coming from an origin ending with "example.com".
- `Array` - set `origin` to an array of valid origins. Each origin can be a `String` or a `RegExp`. For example `["http://example1.com", /\.example2\.com$/]` will accept any request from "http://example1.com" or from a subdomain of "example2.com".
- `Function` - set `origin` to a function implementing some custom logic. The function takes the request origin as the first parameter and a callback (which expects the signature `err [object], allow [bool]`) as the second.
* `methods`: Configures the **Access-Control-Allow-Methods** CORS header. Expects a comma-delimited string (ex: 'GET,PUT,POST') or an array (ex: `['GET', 'PUT', 'POST']`).
* `allowedHeaders`: Configures the **Access-Control-Allow-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Type,Authorization') or an array (ex: `['Content-Type', 'Authorization']`). If not specified, defaults to reflecting the headers specified in the request's **Access-Control-Request-Headers** header.
* `exposedHeaders`: Configures the **Access-Control-Expose-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Range,X-Content-Range') or an array (ex: `['Content-Range', 'X-Content-Range']`). If not specified, no custom headers are exposed.
* `credentials`: Configures the **Access-Control-Allow-Credentials** CORS header. Set to `true` to pass the header, otherwise it is omitted.
* `maxAge`: Configures the **Access-Control-Max-Age** CORS header. Set to an integer to pass the header, otherwise it is omitted.
* `preflightContinue`: Pass the CORS preflight response to the next handler.
* `optionsSuccessStatus`: Provides a status code to use for successful `OPTIONS` requests, since some legacy browsers (IE11, various SmartTVs) choke on `204`.
The default configuration is the equivalent of:
```json
{
"origin": "*",
"methods": "GET,HEAD,PUT,PATCH,POST,DELETE",
"preflightContinue": false,
"optionsSuccessStatus": 204
}
```
For details on the effect of each CORS header, read [this](http://www.html5rocks.com/en/tutorials/cors/) article on HTML5 Rocks.
## Demo
A demo that illustrates CORS working (and not working) using jQuery is available here: [http://node-cors-client.herokuapp.com/](http://node-cors-client.herokuapp.com/)

# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
## Use the built-in
Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
support `Object.assign()` :tada:. If you target only those environments, then by all
means, use `Object.assign()` instead of this package.
## Install
```
$ npm install --save object-assign
```
## Usage
```js
const objectAssign = require('object-assign');
objectAssign({foo: 0}, {bar: 1});
//=> {foo: 0, bar: 1}
// multiple sources
objectAssign({foo: 0}, {bar: 1}, {baz: 2});
//=> {foo: 0, bar: 1, baz: 2}
// overwrites equal keys
objectAssign({foo: 0}, {foo: 1}, {foo: 2});
//=> {foo: 2}
// ignores null and undefined sources
objectAssign({foo: 0}, null, {bar: 1}, undefined);
//=> {foo: 0, bar: 1}
```
## API
### objectAssign(target, [source, ...])
Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

Manipulate the HTTP Vary header
## 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 vary
```
## API
<!-- eslint-disable no-unused-vars -->
```js
var vary = require('vary')
```
### vary(res, field)
Adds the given header `field` to the `Vary` response header of `res`.
This can be a string of a single field, a string of a valid `Vary`
header, or an array of multiple fields.
This will append the header if not already listed, otherwise leaves
it listed in the current location.
<!-- eslint-disable no-undef -->
```js
// Append "Origin" to the Vary header of the response
vary(res, 'Origin')
```
### vary.append(header, field)
Adds the given header `field` to the `Vary` response header string `header`.
This can be a string of a single field, a string of a valid `Vary` header,
or an array of multiple fields.
This will append the header if not already listed, otherwise leaves
it listed in the current location. The new header string is returned.
<!-- eslint-disable no-undef -->
```js
// Get header string appending "Origin" to "Accept, User-Agent"
vary.append('Accept, User-Agent', 'Origin')
```
## Examples
### Updating the Vary header when content is based on it
```js
var http = require('http')
var vary = require('vary')
http.createServer(function onRequest (req, res) {
// about to user-agent sniff
vary(res, 'User-Agent')
var ua = req.headers['user-agent'] || ''
var isMobile = /mobi|android|touch|mini/i.test(ua)
// serve site, depending on isMobile
res.setHeader('Content-Type', 'text/html')
res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
})
```
## Testing
```sh
$ npm test
```
