Animations

A simple animation can be done on the components using CSS. See this demo. More advaned animations can be done using dynamic styles. See this demo

Development

npm start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

Then run either Storybook or the example playground:

Storybook

Run inside another terminal:

npm run storybook

This loads the stories from ./stories.

NOTE: Stories should reference the components as if using the library, similar to the example playground. This means importing from the root project directory. This has been aliased in the tsconfig and the storybook webpack config as a helper.

Example

Then run the example inside another:

cd example
npm i
npm start

The default example imports and live reloads whatever is in /dist, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above. No symlinking required, we use Parcel's aliasing.

To do a one-off build, use npm run build.

To run tests, use npm test.

Configuration

Code quality is set up for you with prettier, husky, and lint-staged. Adjust the respective fields in package.json accordingly.

Jest

Jest tests are set up to run with npm test.

GitHub Actions

• main which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrix
