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/
```

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.format(number value, [options]): string|null
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(1024);
// output: '1KB'
bytes(1000);
// output: '1000B'
bytes(1000, {thousandsSeparator: ' '});
// output: '1 000B'
bytes(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'
bytes(1024, {unitSeparator: ' '});
// output: '1 KB'
```
#### bytes.parse(string|number value): number|null
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
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('1KB');
// output: 1024
bytes('1024');
// output: 1024
bytes(1024);
// output: 1024
```

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 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 (err) {
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 string. 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'})
```
Format an object into a content type string. 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.
