Installing ReScript locally

This track uses ReScript 12 and relies on Node.js 22 or greater. Many systems will have this pre-installed or you may have previously installed it for another track.

Open a terminal and run:

node -v

If Node isn't installed or an older version is listed, please follow the official Node.js installation instructions for your platform.

Installing dependencies

Each ReScript exercise is a self-contained npm project. After downloading an exercise with the Exercism CLI, install the project dependencies including ReScript and you're ready to go:

cd /path/to/exercise
npm install

Editor support

The ReScript Project maintains a list of both official and community-supported editor plugins.
