Chai is available for both node.js and the browser using any test framework you like. There are also a number of other tools that include Chai.
Package is available through npm:
npm install chaiRecommend adding it to package.json devDependancies using a * as the version tag.
This will ensure that you always have the most recent version after running npm install,
which can be especially powerful when paired with a continuous integration tool.
devDependencies: {
"chai": "*",
"mocha": "*" // our preference, but you can use any test runner you like
}Include the chai browser build in your testing suite.
<script src="chai.js" type="text/javascript"></script>This will provide chai as a global object, or define it if you are using AMD.
The latest tagged version will be available for hot-linking at http://chaijs.com/chai.js.
If you prefer to host yourself, use the chai.js file from the root of the github project.
We recommend that you always use a version tag as your starting point, so the
tag download list is the best place to start.
Currently supports all modern browsers: IE 9+, Chrome 7+, FireFox 4+, Safari 5+. Please note
that the should style is currently not compatible with IE9.
If you want to know if your browser is compatible, run the online test suite.
