$ npm start

Generating HTML Components

The components in src/components, as well as the export index in src/index.js are programmatically generated from element definitions in scripts/. To regenerate:

The list of attributes is regenerated by scraping the MDN HTML attribute reference.

$ npm run generate-components

Development

Testing your components in Dash

1. Build development bundle to lib/ and watch for changes

    # Once this is started, you can just leave it running.
    $ npm start
   

2. Install module locally (after every change)

    # Generate metadata, and build the JavaScript bundle
    $ npm run install-local
   
    # Now you're done. For subsequent changes, if you've got `npm start`
    # running in a separate process, it's enough to just do:
    $ python setup.py install
   

3. Run the dash layout you want to test

    # Import dash_core_components to your layout, then run it:
    $ python my_dash_layout.py
   

Installing python package locally

Before publishing to PyPi, you can test installing the module locally:

# Install in `site-packages` on your machine
$ npm run install-local

Uninstalling python package locally

$ npm run uninstall-local
