React Package Starter

This is a simple and slightly opinionated starter kit for developing and publishing React packages. It comes with a several pre-configured tools, so you could focus on coding instead of configuring a project for the nth time.

Getting started

npx degit walkerbrian6/react-tsup-package-start my-react-package

cd my-react-package && git init 

yarn && yarn dev

❗Important note: This project uses yarn for managing dependencies. If you want to use another package manager, remove the yarn.lock and control-f for usages of yarn in the project and replace them with your package manager of choice.

What's included?

• ⚡️tsup - The simplest and fastest way to bundle your TypeScript libraries. Used to bundle package as ESM and CJS modules. Supports TypeScript, Code Splitting, PostCSS, and more out of the box.
• 🔗 Yalc - Better workflow than npm | yarn link for package authors.
• 📖 Storybook - Build UI components and pages in isolation. It streamlines UI development, testing, and documentation.
• 🧪 Jest - A testing framework for JavaScript. Preconfigured to work with TypeScript and JSX.
• 🔼 Release-it - release-it is a command line tool to automatically generate a new GitHub Release and populates it with the changes (commits) made since the last release.
• 🐙 Test & Publish via Github Actions - CI/CD workflows for your package. Run tests on every commit plus integrate with Github Releases to automate publishing package to NPM and Storybook to Github Pages.
• 📄 Commitizen — When you commit with Commitizen, you'll be prompted to fill out any required commit fields at commit time.
• 🚓 Commitlint — Checks that your commit messages meet the conventional commit format.
• 🐶 Husky — Running scripts before committing.
• 🚫 lint-staged — Run linters on git staged files
• 🖌 Renovate - Universal dependency update tool that fits into your workflows. Configured to periodically check your dependencies for updates and send automated pull requests.
• ☑️ ESLint - A linter for JavaScript. Includes a simple configuration for React projects based on the recommended ESLint and AirBnB configs.
• 🎨 Prettier - An opinionated code formatter.

Usage

Developing

Watch and rebuild code with tsup and runs Storybook to preview your UI during development.

yarn dev

Run tests with jest when changes are detected.

yarn test:watch

Building

Build package with tsup for production.

yarn build

Linking

Often times you want to link the package you're developing to another project locally to test it out to circumvent the need to publish it to NPM.

For this we use yalc which is a tool for local package development and simulating the publishing and installation of packages.

In a project where you want to consume your package simply run:

npx yalc link my-react-package
# or
yarn yalc add my-react-package

Learn more about yalc here.

Testing

To run all tests once without watching for changes.

yarn test

To watch for changes and run tests.

yarn test:watch

Committing

When you are ready to commit simply run the following command to get a well formatted commit message. All staged files will automatically be linted and fixed as well.

yarn commit

Releasing, tagging & publishing to NPM

Create a semantic version tag and publish to Github Releases. When a new release is detected a Github Action will automatically build the package and publish it to NPM. Additionally, a Storybook will be published to Github pages.

Learn more about how to use the release-it command here.

yarn release

When you are ready to publish to NPM simply run the following command:

yarn publish

Auto publish after Github Release

❗Important note: in order to publish package to NPM you must add your token as a Github Action secret. Learn more on how to configure your repository and publish packages through Github Actions here.

PostCSS

tsup supports PostCSS out of the box. Simply run yarn add postcss -D add a postcss.config.js file to the root of your project, then add any plugins you need. Learn more how to configure PostCSS here.

Additionally consider using the tsup configuration option injectStyle to inject the CSS directly into your Javascript bundle instead of outputting a separate CSS file.
