Compressible `Content-Type` / `mime` checking.
|
|
## Installation
|
|
```sh
|
$ npm install compressible
|
```
|
|
## API
|
|
<!-- eslint-disable no-unused-vars -->
|
|
```js
|
var compressible = require('compressible')
|
```
|
|
### compressible(type)
|
|
Checks if the given `Content-Type` is compressible. The `type` argument is expected
|
to be a value MIME type or `Content-Type` string, though no validation is performed.
|
|
The MIME is looked up in the [`mime-db`](https://www.npmjs.com/package/mime-db) and
|
if there is compressible information in the database entry, that is returned. Otherwise,
|
this module will fallback to `true` for the following types:
|
|
* `text/*`
|
* `*/*+json`
|
* `*/*+text`
|
* `*/*+xml`
|
|
If this module is not sure if a type is specifically compressible or specifically
|
uncompressible, `undefined` is returned.
|
|
<!-- eslint-disable no-undef -->
|
|
```js
|
compressible('text/html') // => true
|
compressible('image/png') // => false
|
```
