# caniuse-api [](https://travis-ci.org/Nyalab/caniuse-api) [](https://ci.appveyor.com/project/MoOx/caniuse-api/branch/master)
request the caniuse data to check browsers compatibilities
## Installation
```console
$ npm install caniuse-api --save
```
## Usage
```js
const caniuse = require('caniuse-api')
caniuse.getSupport('border-radius')
caniuse.isSupported('border-radius', 'ie 8, ie 9')
caniuse.setBrowserScope('> 5%, last 1 version')
caniuse.getSupport('border-radius')
// ...
```
## API
#### `caniuse.getSupport(feature)`
_ask since which browsers versions a feature is available_
* `y`: Since which browser version the feature is available
* `n`: Up to which browser version the feature is unavailable
* `a`: Up to which browser version the feature is partially supported
* `X`: Up to which browser version the feature is prefixed
```js
caniuse.getSupport('border-radius', true)
/*
[ safari: { y: 3.1, x: 4 },
opera: { n: 10, y: 10.5 },
ios_saf: { y: 3.2, x: 3.2 },
ie_mob: { y: 10 },
ie: { n: 8, y: 9 },
firefox: { a: 2, x: 3.6, y: 3 },
chrome: { y: 4, x: 4 },
and_chr: { y: 39 } ]
*/
```
#### `caniuse.isSupported(feature, browsers)`
_ask if a feature is supported by some browsers_
```js
caniuse.isSupported('border-radius', 'ie 8, ie 9') // false
caniuse.isSupported('border-radius', 'ie 9') // true
```
#### `caniuse.find(query)`
_search for a caniuse feature name_
Ex:
```js
caniuse.find('radius') // ['border-radius']
caniuse.find('nothingness') // []
caniuse.find('css3')
/*
[ 'css3-boxsizing',
'css3-colors',
'css3-cursors-newer',
'css3-cursors',
'css3-tabsize' ]
*/
```
#### `caniuse.getLatestStableBrowsers()`
_get the current version for each browser_
```js
caniuse.getLatestStableBrowsers()
/*
[ 'safari 8',
'opera 26',
'ios_saf 8.1',
'ie_mob 11',
'ie 11',
'firefox 33',
'chrome 39' ]
*/
```
#### `caniuse.getBrowserScope()`
_returns a list of browsers currently used for the scope of operations_
```js
caniuse.getBrowserScope()
/*
[ 'safari',
'opera',
'op_mini',
'ios_saf',
'ie_mob',
'ie',
'firefox',
'chrome',
'android',
'and_uc',
'and_chr' ]
*/
```
#### `caniuse.setBrowserScope(browserscope)`
_if you do not like the default browser scope, you can set it globally by using this method_
* browserscope should be a 'autoprefixer' formatted string
```js
caniuse.setBrowserScope('> 5%, last 2 versions, Firefox ESR, Opera 12.1')
```
