Install dependencies

If you have selected install_dependencies during the prompt, you can skip this part.

1. Install npm packages

   $ npm install
   

2. Create a virtual env and activate.

   $ virtualenv venv
   $ . venv/bin/activate
   

   Note: venv\Scripts\activate for windows

3. Install python packages required to build components.

   $ pip install -r requirements.txt
   

4. Install the python packages for testing (optional)

   $ pip install -r tests/requirements.txt
   

Write your component code in src/lib/components/PeriodicTableInput.react.js.

• The demo app is in src/demo and you will import your example component code into your demo app.
• Test your code in a Python environment:
  1. Build your code

     $ npm run build
     

  2. Run and modify the usage.py sample dash app:

     $ python usage.py
     

• Write tests for your component.
  • A sample test is available in tests/test_usage.py, it will load usage.py and you can then automate interactions with selenium.
  • Do not forget to re-build the components before running the tests.
  • Run the tests with $ pytest tests.
  • The Dash team uses these types of integration tests extensively. Browse the Dash component code on GitHub for more examples of testing (e.g. https://github.com/plotly/dash-core-components)
• Add custom styles to your component by putting your custom CSS files into your distribution folder (dash_mp_components).
  • Make sure that they are referenced in MANIFEST.in so that they get properly included when you're ready to publish your component.
  • Make sure the stylesheets are added to the _css_dist dict in dash_mp_components/__init__.py so dash will serve them automatically when the component suite is requested.
• Review your code

Build process

1. Tag a version by running npm version patch|minor|major

This will automatically bumps the version number in package.json, create a tag in the local repository, and push it to github. A github action will build and publish the python package.

Manually Create a production build and publish:

1. Build your code:

   $ npm run build
   

2. Create a Python tarball

   $ python setup.py sdist
   

   This distribution tarball will get generated in the dist/ folder

3. Test your tarball by copying it into a new environment and installing it locally:

   $ pip install dash_mp_components-x.x.x.tar.gz
   

4. If it works, then you can publish the component to NPM and PyPI:

   1. Publish on PyPI

      $ twine upload dist/*
      

   2. Cleanup the dist folder (optional)

      $ rm -rf dist
      

   3. Publish on NPM (Optional if chosen False in publish_on_npm)

      $ npm publish
      

      Publishing your component to NPM will make the JavaScript bundles available on the unpkg CDN. By default, Dash serves the component library's CSS and JS locally, but if you choose to publish the package to NPM you can set serve_locally to False and you may see faster load times.

5. To publish a new version from github, use npm version

The components are currently published in the test index, so you'll need to specify the url of the index when you install the package pip install --index-url https://test.pypi.org/simple/ dash-mp-components
