11## Installation
12
13```sh
14$ npm install media-typer
15```
16
17## API
18
19```js
20var typer = require('media-typer')
21```
22
23### typer.parse(string)
24
25```js
26var obj = typer.parse('image/svg+xml; charset=utf-8')
27```
28
29Parse a media type string. This will return an object with the following
30properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
31
32 - `type`: The type of the media type (always lower case). Example: `'image'`
33
34 - `subtype`: The subtype of the media type (always lower case). Example: `'svg'`
35
36 - `suffix`: The suffix of the media type (always lower case). Example: `'xml'`
37
38 - `parameters`: An object of the parameters in the media type (name of parameter always lower case). Example: `{charset: 'utf-8'}`
39
40### typer.parse(req)
41
42```js
43var obj = typer.parse(req)
44```
45
46Parse the `content-type` header from the given `req`. Short-cut for
47`typer.parse(req.headers['content-type'])`.
48
49### typer.parse(res)
50
51```js
52var obj = typer.parse(res)
53```
54
55Parse the `content-type` header set on the given `res`. Short-cut for
56`typer.parse(res.getHeader('content-type'))`.
57
58### typer.format(obj)
59
60```js
61var obj = typer.format({type: 'image', subtype: 'svg', suffix: 'xml'})
62```
63
64Format an object into a media type string. This will return a string of the
65mime type for the given object. For the properties of the object, see the
66documentation for `typer.parse(string)`.
