webviz_core_components is a Dash component library for use in webviz. A storybook showing all available components is available at https://equinor.github.io/webviz-core-components/storybook-static.

You can quickly get started with:

1. Run pip install webviz-core-components
2. Run python usage.py
3. Visit http://localhost:8050 in your web browser

How to contribute

Install dependencies

If you want to build and develop yourself, you should fork + clone the repository, and then:

1. Install npm packages.

   npm ci --ignore-scripts --prefix ./react
   

2. Install python packages required to build components.

   pip install .[dependencies]
   pip install dash[dev]
   

3. Install the python packages for testing.

   pip install .[tests]
   pip install dash[testing]
   

   The second of these commands appears to be necessary as long as this pip issue is open.

Write component code in react/src/lib/components/<ComponentName>/<ComponentName>.tsx

• Have a look at other components to see how the directory and file structure looks like.

• The demo app is in react/src/demo and is where you will import an example of your component. To start the existing demo app, run npm start --prefix ./react.

• To test your code in a Python environment:

  1. Build your code

     npm run build --prefix ./react
     

  2. Install the Python pacakge in development mode (if not already done and assuming you are using a virtual environment):

     pip install -e .
     

  3. Create a new example in examples/ which uses your new component.

• Write tests for your component.

  • Python
    • Python tests exist in tests/. Take a look at them to see how to write tests using the Dash test framework.
    • Run the tests with pytest tests.
  • JavaScript
    • JavaScript tests exist in react/tests. Take a look at them to see how to write tests using the Jest test framework.

• Add custom styles to your component by putting your custom CSS files into your distribution folder (webviz_core_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 webviz_core_components/__init__.py so dash will serve them automatically when the component suite is requested.
  • You can also include stylesheets directly in your component by adding the stylesheet to your component's directory and importing it via import "./<ComponentName>.css. Make sure that the class names in your stylesheet are starting with your component's name and two underscores: .MyComponent__MyClassName.
