THEIA-UIKIT - React Component library
Welcome to theia-uikit, our React component library! Let’s get you oriented with what’s here and how to use it.
This project was created using TSDX setup, wich is meant for developing React component libraries (not apps!) that can be published to NPM.
If you’re new to TypeScript and React, checkout this handy cheatsheet

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 # or 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:
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.
Example
Then run the example inside another:
cd example
yarn # or npm i to install dependencies
yarn start # or 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, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above.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 yarn build
or npm run build
.
To run tests, use yarn test
or 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 yarn test
or npm test
.
Bundle analysis
Calculates the real cost of your library using size-limit with npm run size
and visulize it with npm run analyze
.
Setup Files
This is the folder structure we set up for you:
/example
index.html
index.tsx # test your component here in a demo app
package.json
tsconfig.json
/src
index.tsx # EDIT THIS
/test
blah.test.tsx # EDIT THIS
/stories
Thing.stories.tsx # EDIT THIS
/.storybook
main.js
preview.js
.gitignore
package.json
README.md # EDIT THIS
tsconfig.json
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 matrixsize
which comments cost comparison of your library on every pull request using size-limit
Optimizations
Please see the main tsdx
optimizations docs. In particular, know that you can take advantage of development-only optimizations:
// ./types/index.d.ts
declare var __DEV__: boolean;
// inside your code...
if (__DEV__) {
console.log('foo');
}
You can also choose to install and use invariant and warning functions.
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
Alternatively, if you already have a git repo connected, you can set up continuous deployment with Netlify:
netlify init
# build command: yarn build && cd example && yarn && yarn build
# directory to deploy: example/dist
# pick yes for netlify.toml
Named Exports
Per Palmer Group guidelines, always use named exports. Code split inside your React app instead of your React library.
Including Styles
There are many ways to ship styles, including with CSS-in-JS. TSDX has no opinion on this, configure how you like.
For vanilla CSS, you can include it at the root directory and add it to the files
section in your package.json
, so that it can be imported separately by your users and run through their bundler's loader.
Publishing to NPM
We recommend using np.
