Requirements

On macOS

• Node.js (brew install nvm, nvm install 22, nvm use 22)
• PNPM (npm install -g pnpm@9)

On Linux

• Node.js (nvm install 22, nvm use 22)
• PNPM (npm install -g pnpm@9)

Setup

• pnpm run setup (install required dependencies and set up project)

Usage

• pnpm t (run all tests)
• pnpm run test:specs (run unit and integration tests)
• pnpm run test:bazel (run unit and integration tests with bazel)
• pnpm run test:knip (check for unused code)
• pnpm run test:lint (check for linting issues)
• pnpm run test:format (format code)
• pnpm run test:spell (check spelling)

Issue
