Yarn Berry TypeScript Monorepo Template

This repo is a template for creating a monorepo that uses TypeScript, Jest, and RollupJS. These are the tools I gravitate towards so I decided I would make a template. If anybody finds any bugs, you can submit and issue or create a PR and I will review it. The TypeScript and ESLint configs are setup for Node projects but can easily be modified for browser projects.

I will continue to add new scripts to this repository as I create useful ones.

Getting Started

There is a command in the package.json that will do the setup for you, but this section will also run you through how to do it manually. The command to setup the repo is:

yarn setup

To setup the repo for yourself, run the following command:

yarn policies set-version berry && yarn set version berry

You will now have Yarn Berry (Yarn 2) setup for this directory. Next you will need to install the plugins and other dependencies. To install the plugins run this command:

yarn install

To install the dependencies, run the following command:

yarn

You now have this repo setup!

Creating a New Package

Generally this is a very manual process, but since most of the time the packages all need the same configuration in a monorepo, I built a script that will create a new package in the packages directory. In order to create a new package, run the following command in the root of the repository:

yarn new-package <package-name>

Replace <package-name> with the name of your package. The script that this command runs can be found in packages/scripts/src/new-package.ts. The following are the steps this scripts takes:

1. Creates the directory in the packages directory with the name you supplied
2. Creates the src directory
3. Creates src/index.ts
4. Creates the package.json file
5. Creates the README.md file
6. Copies all the config files from configs
