React (v16.8.0+), Typescript, Yarn & Lerna Monorepo

Starting point for a Typescript, React (v16.8.0+, tested up to v16.13.1), Yarn & Lerna monorepo project with full setup for ESLint and Prettier.

Stack

This project is initialized with Create React App consisting of:

  • TypeScript
  • React (v16.8.0+, tested up to v16.13.1)
  • react-scripts (react-scripts v3+, tested up to v3.4.0, from createReactApp)
  • react-testing-library (not Enzyme)
  • Yarn Workspaces (multiple packages architecture)
  • Lerna (tool for managing the monorepo packages)
  • SASS/SCSS
  • ESLint (instead of deprecated TSLint)
  • Prettier

Content

The project now consists of 3 packages.

  • www: create-react-app with TypeScript (react v16.13.1+, react-scripts v3.4.0)
  • shared: react components with TypeScript (react v16.13.1+)
  • utils: shared functions with TypeScript

Get Started

Make sure you run Node.js v10.15+

To install check (Node.js installation or Node Version Manager installation).

Clone or copy this repo

curl -L https://github.com/michielbouw/react-typescript-yarn-lerna-monorepo-eslint-prettier-boilerplate/archive/master.zip | tar zx
mv react-typescript-eslint-prettier-boilerplate APP_NAME
cd APP_NAME

or

git clone git@github.com:michielbouw/react-typescript-yarn-lerna-monorepo-eslint-prettier-boilerplate.git APP_NAME
cd APP_NAME

yarn install

Note: this project is initialized with Yarn.

Adding / removing packages

To add a new package create a new folder in under packages and copy the
.eslint.json, package.json, tsconfig.json from another similar project in here.
After that you can setup your project how you like it.

(you can also extend the custom scripts from the main package.json
or already include in as dependency for another package).

After changing the packages run yarn clean:update to clean & reinit the workspaces.

After changing the external libraries or peerDependencies it is good to clean the repo
by removing the node_modules folder rm -rf node_modules and reinstalling yarn install. And after that run yarn clean:update to clean & reinit the workspaces.

Development Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn typecheck

Launches the typescript check for code to check for TypeScript compilation errors or warnings.

yarn lint

Launches the linter for code to check for code layout errors or warnings.

yarn lint:fix

Launches the linter for code to check for code layout errors or warnings, and fixes the ones that can be fixed automatically.

yarn test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

Production Scripts

yarn build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.
