request the caniuse data to check browsers compatibilities

Package Exports

  • caniuse-api

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (caniuse-api) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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
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

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:

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

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

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
caniuse.setBrowserScope('> 5%, last 2 versions, Firefox ESR, Opera 12.1')
