    alloy is a UI library that specialises in creating reusable behaviours and components that are not opinionated about DOM structure and styling. It is a very low-level library.



    A webserver to run demos, npm, webpack is required to run and develop alloy

    alloy is available as an npm package. You can install it via the npm package @ephox/alloy

    yarn install the dependencies webpack compile the src code


    Running Tests

    alloy uses bedrock to run its tests. If you are running the browser tests, you may need to ensure that you have valid webdrivers on your path. You can install many of the webdrivers through npm.

    There are four kinds of tests that alloy runs:

    • atomic tests
    • headless tests
    • browser tests
    • webdriver tests

    Running Console Tests

    $ yarn run test

    This will run the console tests in chrome-headless.

    Running Browser Tests

    The browser tests are in the src/test/js/browser directory. They do not require a webdriver and can be run using the bedrock mode (rather than bedrock-auto).

    $ bedrock --testdir src/test/js/browser

    In this mode, bedrock will not open the browser, nor will it close it. This mode is used for development and debugging.

    Running Webdriver Tests

    Some tests in alloy need to access raw WebDriver APIs like sendKeys. This allows tests to use selenium to provide actual real key events, rather than simulated JavaScript events. However, to run these tests, you need to use bedrock-auto. The tests are stored in the src/test/js/webdriver directory.

    For example, to run the tests on Chrome:

    $ bedrock-auto -b chrome --testdir src/test/js/webdriver

    Note, webdriver tests are still rather fragile.

    Alloy APIs

    We are currently working on documenting the alloy APIs. For now, there are many demos available in src/demo/html that demonstrate how to use alloy. Be aware that the library is still in a state of constant adjustment.
