📦 Typescript • React • Package Starter

A slightly opinionated starter kit for developing TypeScript and/or React NPM packages. It comes with a several pre-configured tools, so you could focus on coding instead of configuring a project for the nth time. From building to releasing a package, this starter kit has you covered.

👋 Hello there! Follow me @linesofcode or visit linesofcode.dev for more cool projects like this one.

🏃 Getting started

npx degit TimMikeladze/typescript-react-package-starter my-package

cd my-package && git init

pnpm install && pnpm dev

❗Important note: This project uses pnpm for managing dependencies. If you want to use another package manager, remove the pnpm-lock.yaml and control-f for usages of pnpm in the project and replace them with your package manager of choice. If you don't have pnpm installed and want to use it, you can install it by running npm install -g pnpm.

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.
• 📖 Storybook - Build UI components and pages in isolation. It streamlines UI development, testing, and documentation.
• 🧪 Vitest - A testing framework for JavaScript. Preconfigured to work with TypeScript and JSX.
• ✅ Biome - Format, lint, and more in a fraction of a second.
• 🪝 Lefthook — Run pre-commit hooks, lints staged files, executes tests, and more.
• 🔼 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.
• 🤖 Dependabot - Github powered dependency update tool that fits into your workflows. Configured to periodically check your dependencies for updates and send automated pull requests.
• 🏃‍♀️‍➡️ TSX - Execute TypeScript files with zero-config in a Node.js environment.

Usage

💻 Developing

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

pnpm dev

Run all tests and watch for changes

pnpm test

🏗️ Building

Build package with tsup for production.

pnpm build

▶️ Running files written in TypeScript

To execute a file written in TypeScript inside a Node.js environment, use the tsx command. This will detect your tsconfig.json and run the file with the correct configuration. This is perfect for running custom scripts while remaining type-safe.

pnpm tsx ./path/to/file.ts

This is useful for running scripts, starting a server, or any other code you want to run while remaining type-safe.

🖇️ Linking

Often times you want to link this package to another project when developing locally, circumventing the need to publish to NPM to consume it.

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

pnpm link my-package --global

📩 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.

pnpm commit

✅ Linting

To lint and reformat your code at any time, simply run the following command. Under the hood, this uses Biome. If you use VSCode, I suggest installing the official biome extension.

pnpm lint

🔖 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.

pnpm release

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

pnpm publish

🤖 Auto publish after Github Release (or manually by dispatching the Publish workflow)

❗Important note: in order to automatically publish a Storybook on Github Pages you need to open your repository settings, navigate to "Actions" and enable "Read & write permissions" for Workflows. Then navigate to "Pages" and choose "GitHub Actions" as the source for the Build and Deployment. After a successful deployment you can find your Storybook at https://<your-github-username>.github.io/<your-repository-name>/.

❗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.

🎨 CSS & PostCSS

To bundle CSS files with your package that you intend on users to import within their own project, a few extra steps are required.

1. Add your CSS files to the src directory. For example, src/styles.css.
2. Modify tsup.config.ts file to include your CSS file as an entry point. For example:

import { defineConfig } from "tsup";

export default defineConfig({
	entry: ["src/index.ts", "src/styles.css"],
	// ...
});

3. Modify package.json to include the CSS file as an exports entry. For example:

{
	"exports": {
		"./styles.css": "./dist/styles.css"
	}
}

4. Now consumers of your package can import your CSS file anywhere in their project. For example:

import "your-package/styles.css";

Alternatively, if your package has a hard dependency on a CSS file and you want it to always be loaded when your package is imported, you can import it anywhere within your package's code and it will be bundled with-in your package.

tsup supports PostCSS out of the box. Simply run pnpm 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.
