Development

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Make sure you have the LTS version of Node (18.7) installed in your machine. We recommend to use nvm (Node Version Manager).

This monorepository uses Turborepo to manage dependencies and scripts. The first step is to install the local node dependencies:

pnpm install

There are two main ways to develop new components:

• Storybook App (Vite)
• Watch the React UI Library (Rollup) + NextJs

Development Storybook

To watch changes in the React Library and start the Storybook App, just run:

pnpm run storybook

This instance of Storybook uses the source code to compile the React Stories. It's faster than watching changes and reloading and it gets HMR. That's the reason components are imported using @chepe/ui/src instead of @chepe/ui.

Development NextJs

To watch changes in the React Library and start the Next.Js App, just run:

pnpm run web

Contrary to the Storybook instance, this React App uses the bundled code inside React. It should be really similar to the final package being used by product teams.

Continuous Integration

This project has multiple GitHub Actions for build, test and deployment.

You can finds all the GitHub actions files inside .github/workflows/

Name	File	Description
Build	ci.yml	Builds the main Component Library. (@chepe/ui)
Storybook Tests	storybook-tests.yml	Turns all the Storybook stories into executable tests including a11y.

Tools

Add a new Component

You can add a new Component Boilerplate using the Generator Tool.

npm run generate:component --name=Heading
npm run generate:component --name=InputField
