Git Workflow

This repository includes a pre-commit hook that automatically builds the server before each commit. This ensures that the build files are always up-to-date in the repository.

The build folder is included in the git repository to make it easier to use the package with npx without having to build it first.

To set up the pre-commit hook after cloning the repository:

pnpm install

This will install dependencies and set up the pre-commit hook via Husky.
