TAIKAI Design System

Check our components in StoryBook or in Chromatic library

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:

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:

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
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The default example imports and live reloads whatever is in /dist, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above.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.

To debug tests

import { screen } from '@testing-library/react';
screen.logTestingPlaygroundURL();

Bundle analysis

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

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

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.

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

Compiling Locally

When it is published or compiled locally, it allows to rapidly test the design system as would the final developer

• Change the package.json version property. For instance, if the version is currently at 2.0.0-beta.10, change it to 2.0.0-beta.11
• Run the command npm run pack, and you will find a file with the name taikai-taikai-design-system-2.0.0-beta.11.tgz at the root of your project. Copy the filepath of this file and move to the next step
• Now, in one of your separated projects, run npm i [filepath-copied-above]

Publishing to Github Package Registry

We are using np

npm install --global np

Get Github Personnal Access Token

Follow this guide: https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/creating-a-personal-access-token

you need the following scopes (read:packages, write:packages, delete:packages, repo).

Once you get the TOKEN, you can login:

$ npm login --scope=@OWNER --registry=https://npm.pkg.github.com

> Username: USERNAME
> Password: TOKEN
> Email: PUBLIC-EMAIL-ADDRESS

ESLint configuration for VSCode

Add the following config to the file: .vscode/settings.json

{
  "eslint.options": {
    "configFile": ".eslintrc.js"
  },
  "eslint.validate": ["typescript", "typescriptreact"],
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
  }
}
