Component library example with TSDX & Storybook

This TSDX setup is meant for developing React component libraries (not apps!) that can be published to npm.

Commands

TSDX scaffolds your new library inside /src, and also sets up a Parcel-based playground for it inside /example.

The recommended workflow is to run TSDX in one terminal:

yarn 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:

yarn 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.

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 yarn test.

Bundle analysis

Calculates the real cost of your library using size-limit with yarn run size and visulize it with yarn run analyze.

React Testing Library

We do not set up react-testing-library for you yet, we welcome contributions and documentation on this.

Rollup

TSDX uses Rollup as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.

TypeScript

tsconfig.json is set up to interpret dom and esnext types, as well as react for jsx. Adjust according to your needs.

Continuous Integration

GitHub Actions

Two actions are added by default:

• main which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrix
• size which comments cost comparison of your library on every pull request using size-limit

Module Formats

CJS, ESModules, and UMD module formats are supported.

The appropriate paths are configured in package.json and dist/index.js accordingly. Please report if any issues are found.

Deploying the Example Playground

The Playground is just a simple Parcel app, you can deploy it anywhere you would normally deploy that. Here are some guidelines for manually deploying with the Netlify CLI (npm i -g netlify-cli):

cd example # if not already in the example folder
npm run build # builds to dist
netlify deploy # deploy the dist folder

Named Exports

Per Palmer Group guidelines, always use named exports. Code split inside your React app instead of your React library.

Publishing to npm

yarn deploy
