Development

Creating a new package or component

• Copy the template in packages/sample-package and rename files and variables to your new component where applicable.

# from project root
cp -r packages/sample-package packages/new-package-name

• Once renamed, export the new component's storybook file from index.js in the project root.
• Once you've implemented your package, export public modules from index.ts in the package folder. Follow the steps for changing existing components (below) to publish your new package.

Changing existing components

• If it's not already there, create a storybook lit component at packages/component-name/src/component-name-storybook.ts, and in index.js of the root project folder, ensure you export the storybook web component.
• In separate tabs, run yarn dev in the root (storybook server) and yarn dev from within the package folder(s) you are making changes to (component server(s)).
• Now, changes you make to component files, your storybook web component, and storybook.html will auto-appear on save at http://127.0.0.1:8001/storybook.html.
• Your storybook web component is also now available for use in storybook.html. Add your storybook component to this file.
• Implement your storybook component with multiple examples of the component, demonstrating its capabilities. Document in html what each example represents. When making changes to a component, use the storybook as a simple test environment.
• Make the code changes on a new branch, open an MR against master.
• In your changes, make sure you increment the version number in the package.json file in each of the packages you have made changes to. For breaking changes, bump the major version (0.x.x). If adding a medium-to-large feature(s) without breaking changes, bump the minor version (x.0.x). For internal implementation changes and very small feature tweaks, bump the patch version (x.x.0).
• Get a fellow maintainer to review and merge your code.
• Once the code is on master, the maintainer will run an npm release with the new version(s) and your package(s) will be available for upgrade in your repository via yarn upgrade

Sample component TODOs:

• ✅ prettier
• ✅ linter
• ✅ small bundle for publishing
• ✅ storybook
• testing? (storybook can cover this in a sense)
