DASH elements

Dash elements are a collection of implementations of common web UI patterns using modern web technologies like Custom Elements v1 and ESnext with a special focus on accessibility, performance and progressive enhancement. Their purpose is to be an educational resource. Users are supposed to read their implementation rather than just using the elements.

Demos

You can run the demos locally, after you build them:

npm install  # if you haven't already
npm run build
python -m SimpleHTTPServer  # or your favourite local server

In your browser, navigate to http://localhost:8000/docs (or the port that you're running the local server from.)

Testing

Tests are written using Mocha and Chai. Each component has tests.

Local

Tests run using Karma. Run the tests with

$ npm test

This assumes that Chrome, Firefox and Safari are installed as the tests run in all of these browser (using the Custom Elements v1 Polyfill).

Local + Docker (or Travis)

Tests can also run in a Docker container (as we do on Travis):

$ npm run docker

This builds a docker image googlechrome/dash-elements and runs it. The dockerized tests use Chrome only.

Staging

All branches and PRs are built and uploaded on Travis CI. The staged version can be viewed at https://dash-elements.surma.link/<commit hash>.
