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
<!-- eslint-disable no-unused-vars -->
```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/
```

# Upgrade Guide
### 0.15.x -> 0.16.0
#### `Promise` Type Declarations
The `Promise` type declarations have been removed from the axios typings in favor of the built-in type declarations. If you use axios in a TypeScript project that targets `ES5`, please make sure to include the `es2015.promise` lib. Please see [this post](https://blog.mariusschulz.com/2016/11/25/typescript-2-0-built-in-type-declarations) for details.
### 0.13.x -> 0.14.0
#### TypeScript Definitions
The axios TypeScript definitions have been updated to match the axios API and use the ES2015 module syntax.
Please use the following `import` statement to import axios in TypeScript:
```typescript
import axios from 'axios';
axios.get('/foo')
.then(response => console.log(response))
.catch(error => console.log(error));
```
#### `agent` Config Option
The `agent` config option has been replaced with two new options: `httpAgent` and `httpsAgent`. Please use them instead.
```js
{
// Define a custom agent for HTTP
httpAgent: new http.Agent({ keepAlive: true }),
// Define a custom agent for HTTPS
httpsAgent: new https.Agent({ keepAlive: true })
}
```
#### `progress` Config Option
The `progress` config option has been replaced with the `onUploadProgress` and `onDownloadProgress` options.
```js
{
// Define a handler for upload progress events
onUploadProgress: function (progressEvent) {
// ...
},
// Define a handler for download progress events
onDownloadProgress: function (progressEvent) {
// ...
}
}
```
### 0.12.x -> 0.13.0
The `0.13.0` release contains several changes to custom adapters and error handling.
#### Error Handling
Previous to this release an error could either be a server response with bad status code or an actual `Error`. With this release Promise will always reject with an `Error`. In the case that a response was received, the `Error` will also include the response.
```js
axios.get('/user/12345')
.catch((error) => {
console.log(error.message);
console.log(error.code); // Not always specified
console.log(error.config); // The config that was used to make the request
console.log(error.response); // Only available if response was received from the server
});
```
#### Request Adapters
This release changes a few things about how request adapters work. Please take note if you are using your own custom adapter.
1. Response transformer is now called outside of adapter.
2. Request adapter returns a `Promise`.
This means that you no longer need to invoke `transformData` on response data. You will also no longer receive `resolve` and `reject` as arguments in your adapter.
Previous code:
```js
function myAdapter(resolve, reject, config) {
var response = {
data: transformData(
responseData,
responseHeaders,
config.transformResponse
),
status: request.status,
statusText: request.statusText,
headers: responseHeaders
};
settle(resolve, reject, response);
}
```
New code:
```js
function myAdapter(config) {
return new Promise(function (resolve, reject) {
var response = {
data: responseData,
status: request.status,
statusText: request.statusText,
headers: responseHeaders
};
settle(resolve, reject, response);
});
}
```
See the related commits for more details:
- [Response transformers](https://github.com/mzabriskie/axios/commit/10eb23865101f9347570552c04e9d6211376e25e)
- [Request adapter Promise](https://github.com/mzabriskie/axios/commit/157efd5615890301824e3121cc6c9d2f9b21f94a)
### 0.5.x -> 0.6.0
The `0.6.0` release contains mostly bug fixes, but there are a couple things to be aware of when upgrading.
#### ES6 Promise Polyfill
Up until the `0.6.0` release ES6 `Promise` was being polyfilled using [es6-promise](https://github.com/jakearchibald/es6-promise). With this release, the polyfill has been removed, and you will need to supply it yourself if your environment needs it.
```js
require('es6-promise').polyfill();
var axios = require('axios');
```
This will polyfill the global environment, and only needs to be done once.
#### `axios.success`/`axios.error`
The `success`, and `error` aliases were deprectated in [0.4.0](https://github.com/mzabriskie/axios/blob/master/CHANGELOG.md#040-oct-03-2014). As of this release they have been removed entirely. Instead please use `axios.then`, and `axios.catch` respectively.
```js
axios.get('some/url')
.then(function (res) {
/* ... */
})
.catch(function (err) {
/* ... */
});
```
#### UMD
Previous versions of axios shipped with an AMD, CommonJS, and Global build. This has all been rolled into a single UMD build.
```js
// AMD
require(['bower_components/axios/dist/axios'], function (axios) {
/* ... */
});
// CommonJS
var axios = require('axios/dist/axios');

The modules under `adapters/` are modules that handle dispatching a request and settling a returned `Promise` once a response is received.
## Example
```js
var settle = require('./../core/settle');
module.exports = function myAdapter(config) {
// At this point:
// - config has been merged with defaults
// - request transformers have already run
// - request interceptors have already run
// Make the request using config provided
// Upon response settle the Promise
return new Promise(function(resolve, reject) {
var response = {
data: responseData,
status: request.status,
statusText: request.statusText,
headers: responseHeaders,
config: config,
request: request
};
settle(resolve, reject, response);
// From here:
// - response transformers will run
// - response interceptors will run
});
