create-relay-app

Easy configuration of Relay.js for existing projects

Motivation

Setting up Relay can be quite time consuming, since there are many setup steps that might differ depending on the toolchain you use.

The goal of this project is to automate the setup process as much as possible and give you a fast and consistent configuration experience across the most popular React toolchains.

Contrary to many existing tools that aim to solve similiar use cases, this project isn't simply scaffolding a pre-configured boilerplate. We actually analyze your existing code and only insert the necessary Relay configuration pieces.

Supported toolchains

create-relay-app supports:

• Next.js
• Vite.js
• Create React App

Usage

1. Scaffold a new project using the toolchain of your choice (as long as it's supported)
   • Next.js
   • Vite.js
   • Create React App
2. If you are inside a Git repository, ensure your working directory is clean, by commiting or discarding any changes.
3. Run the script inside of the scaffolded directory:

npm/yarn/pnpm create @tobiastengler/relay-app

Note: You can specify -i after the command to walk through an interactive prompt, instead of the script inferring your project's details.

1. Follow the displayed Next steps to complete the setup (You can also find them here)

Arguments
