Unit tests
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 the trigger functionality. Instead, if you'd like to have control over async tests, use the
src/addTest feature, and any test that you set will automatically expose and trigger the on 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 your browser of choice with this command:
npm run serve-gh-pages
and navigate to these two URLs:
http://localhost:8080/test/unit.html
http://localhost:8080/test/integration.html
Integrating Modernizr with Build Tools
This section provides guidance on how to integrate Modernizr with various build tools and frameworks, making it easier to use in your projects.
1. Integrating with Webpack
To integrate Modernizr with Webpack, follow these steps:
-
Install Modernizr:
npm install modernizr --save
-
Create a Modernizr Configuration File:
Create a file named modernizr-config.js in your project root:
module.exports = {
"feature-detects": [
"test/feature1",
"test/feature2",
// Add more feature detects as needed
]
};
-
Update Webpack Configuration:
Modify your Webpack configuration file (e.g., webpack.config.js) to include the Modernizr plugin:
const ModernizrWebpackPlugin = require('modernizr-webpack-plugin');
module.exports = {
// Other configurations...
plugins: [
new ModernizrWebpackPlugin({
"feature-detects": [
"test/feature1",
"test/feature2"
]
})
]
};
-
Build Your Project:
Run your Webpack build process:
npm run build
2. Integrating with Gulp
If you are using Gulp, you can integrate Modernizr as follows:
-
Install Modernizr:
npm install modernizr --save-dev
-
Create a Gulp Task:
In your gulpfile.js, add a task to build Modernizr:
const gulp = require('gulp');
const modernizr = require('modernizr');
gulp.task('modernizr', function() {
return modernizr.build({
"feature-detects": [
"test/feature1",
"test/feature2"
]
}).pipe(gulp.dest('dist/'));
});
-
Run the Gulp Task:
Execute the task to generate the Modernizr build:
gulp modernizr
3. Integrating with Parcel
For projects using Parcel, you can integrate Modernizr as follows:
-
Install Modernizr:
npm install modernizr --save
-
Create a Modernizr Configuration File:
Similar to the Webpack setup, create a modernizr-config.js file:
module.exports = {
"feature-detects": [
"test/feature1",
"test/feature2"
]
};
-
Update Parcel Configuration:
You can use a plugin like parcel-plugin-modernizr to integrate Modernizr:
npm install parcel-plugin-modernizr --save-dev
-
Build Your Project:
Run Parcel to build your project:
parcel build index.html
Conclusion
Integrating Modernizr with your build tools can enhance your web applications by allowing you to detect and respond to the capabilities of the user's browser. Follow the steps above to set up Modernizr with your preferred build tool.
For more information, refer to the Modernizr documentation.
