React Library Template

This template repository is your shortcut to building awesome React components and libraries!

Forget about the tedious setup – we've got you covered. Focus on writing your code, and let this template handle the rest.

Features

• TypeScript & JavaScript: Write your code in the language you prefer.
• Blazing fast: pnpm for speedy package management and Vite for lightning-fast builds.
• Husky enforces pre-commit hooks, Eslint will keep your code tidy and consistent.
• Jest and react-testing-library help you write robust tests.
• Optional Tailwind CSS: If you're into it, you can easily enable Tailwind CSS for styling.

This template is your starting point for building high-quality React libraries. Clone it, customize it, and let's build something amazing!

Quickstart

Prerequisites

1. Install Node >= 20.x.
2. Install pnpm. E.g. corepack prepare pnpm@latest --activate.

Installation

Manually clone repo or use degit.

# With CSS Modules config
npx degit github:morewings/react-library-template my-library
# With Tailwind CSS config
npx degit github:morewings/react-library-template#tailwind my-library
cd ./my-library
pnpm i

Improve tree shaking

The default settings allow modern bundlers such as Vite and esbuild successfully tree-shake unused modules from the bundle. Unfortunately there are problems with Next.js and Webpack not capable to tree-shake single file ES Module.

In order to fix this enable preserveModules setting in Rollup options.

import {defineConfig} from 'vite';

export default defineConfig(() => ({
    // ...
    build: {
        lib: {
            // ...
            fileName: (format, entryName) => {
                // Create entry file(s) inside the bundle
                if (entryName === 'src/lib/index') {
                    return `index.${format === 'es' ? 'js' : 'cjs'}`;
                    // Organize external dependencies which included in the bundle
                } else if (entryName.includes('node_modules')) {
                    return `external/module.${format === 'es' ? 'js' : 'cjs'}`;
                }
                // Keep other modules in places
                return `${entryName}.${format === 'es' ? 'js' : 'cjs'}`;
            },
            // Change bundle formats to ES Modules and commonJS.
            // UMD bundle will not work with preserveModules:true
            formats: ['es', 'cjs'],
        },
        rollupOptions: {
            // ...
            output: {
                // ...
                preserveModules: true,
            },
        },
    },
}));
