A node library to do compatibility validation for support of HTML5, CSS3, SVG and more in desktop and mobile browsers. Based on data from Fyrd's caniuse.

Installing

Usage

Check if CSS 3D transform is supported on android 2.3:

var query = require('caniuse').query
    result;

result = query('transforms3d', {name:'android', version: '2.3'});

// query result:
// -2 : NOT supported
// -1 : NOT supported, but has polyfill available
//  0 : unknown
//  1 : partially supported, and vendor prefixed
//  2 : partially supported
//  3 : supported, and vendor prefixed
//  4 : supported

if (result > 2) {
    console.log('Fully supported!');
}

Check if @font-face is supported on latest version of IE:

var query = require('caniuse').query
    result;

result = query('fontface', 'ie');

if (result > 2) {
    console.log('Fully Supported!');
}

You may want to update the data from caniuse:

cd tool
node updateData.js

You can also update data in code:

var updateData = require('caniuse').updateData;
updateData(function(err) {
    if (err) {
        throw err;
    }
    // do some query
});
