Modernizr tests which native CSS3 and HTML5 features are available in the current UA and makes the results available to you in two ways: as properties on a global
Modernizr
object, and as classes on the<html>
element. This information allows you to progressively enhance your pages with a granular level of control over the experience.Breaking changes with v4
Dropped support for node versions <= 10, please upgrade to at least version 12

New Asynchronous Event Listeners
Often times people want to know when an asynchronous test is done so they can allow their application to react to it. In the past, you've had to rely on watching properties or
<html>
classes. Only events on asynchronous tests are supported. Synchronous tests should be handled synchronously to improve speed and to maintain consistency.The new API looks like this:
// Listen to a test, give it a callback Modernizr.on('testname', function( result ) { if (result) { console.log('The test passed!'); } else { console.log('The test failed!'); } });
We guarantee that we'll only invoke your function once (per time that you call
on
). We are currently not exposing a method for exposing thetrigger
functionality. Instead, if you'd like to have control over async tests, use thesrc/addTest
feature, and any test that you set will automatically expose and trigger theon
functionality.Getting Started
- Clone or download the repository
- Install project dependencies with
npm install
Building Modernizr
From javascript
Modernizr can be used programmatically via npm:
var modernizr = require("modernizr");
A
build
method is exposed for generating custom Modernizr builds. Example:var modernizr = require("modernizr"); modernizr.build({}, function (result) { console.log(result); // the build });
The first parameter takes a JSON object of options and feature-detects to include. See
lib/config-all.json
for all available options.The second parameter is a function invoked on task completion.
From the command-line
We also provide a command line interface for building modernizr. To see all available options run:
./bin/modernizr
Or to generate everything in 'config-all.json' run this with npm:
npm start //outputs to ./dist/modernizr-build.js
Testing Modernizr
To execute the tests using mocha-headless-chrome on the console run:
npm test
You can also run tests in the browser of your choice with this command:
npm run serve-gh-pages
and navigating to these two URLs:
http://localhost:8080/test/unit.html http://localhost:8080/test/integration.html
