DevX-UI Developer Guide

Welcome to the DevX-UI project! We bootstrapped this project with TSDX. Let’s get you oriented with what’s here and how to use it.

If you’re new to TypeScript and React, checkout this handy cheatsheet

Commands

The library is scaffolded inside /src, and a Parcel-based playground is set up for the lib inside /example.

The recommended workflow is to run TSDX in one terminal:

npm start # or 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:

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 # or yarn to install dependencies
npm start # or yarn 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The default example imports and live reloads whatever is in /dist, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above.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 or yarn build.

To run tests, use npm test or yarn 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 or yarn 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
  ...             # components go here
  index.tsx
/test
  ...             # tests go here
/stories
  ...             # stories go here
/.storybook
  main.js
  preview.js
.gitignore
package.json
README.md
tsconfig.json

Continuous Integration

GitHub Actions

Here is the list of actions set up for this project:

• 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
• chromatic which publishes storybook to Chromatic
• release which publishes the library to npm

Module Formats

CJS, ESModules, and UMD module formats are supported.

The appropriate paths are configured in package.json and dist/index.js accordingly.

Deploying the Example Playground

The Playground is just a simple Parcel app. Here are some guidelines for manually deploying with the Vercel CLI (npm i -g vercel):

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