Development ​

Getting Started ​

  1. Clone the repository:
    bash
    git clone https://github.com/tillsanders/esm-itter.git
cd esm-itter
  2. Install dependencies:
    bash
    npm install

Project Structure ​

  • src/ — Main source code (TypeScript, ESM)
  • benchmarks/ — Performance benchmarks (requires separate install)
  • test/ — Unit tests
  • docs/ — Documentation

Useful Scripts ​

  • npm test — Run unit tests
  • npm run coverage — Generate code coverage report
  • npm run build — Build the module (TypeScript compilation)
  • npm run lint — Run linter
  • npm run prettier — Format code with Prettier

Running Benchmarks ​

Benchmarks are not included in the npm package. To run them:

  1. Install dependencies in the benchmarks folder:
    bash
    cd benchmarks
npm install
cd ..
  2. Run the benchmark:
    bash
    npm run benchmark

Output is displayed in the console, showing performance comparisons with other event emitters.

Testing ​

Unit tests are written in TypeScript and can be run with npm test. Coverage reports are generated with npm run coverage.

Documentation ​

The documentation is built using VitePress and can be found in the docs/ directory. To run a local development server for the documentation, use:

bash
npm run docs:dev

This will start a local server at http://localhost:5173/esm-itter where you can view the documentation.

Publishing ​

ESMitter is published to to npm using GitHub Actions. To publish a new version, update the version in package.json and jsr.json, run npm install and push the changes to the main branch. Create a new release on GitHub, and the CI will automatically publish the new version to npm and jsr after running tests and checks.

Contributing ​

Contributions are welcome! Please:

  • Follow the existing code style and conventions.
  • Write unit tests for new features or bug fixes.
  • Update documentation as needed.
  • Open a pull request with a clear description of your changes.

Troubleshooting ​

  • If you encounter issues with dependencies, try deleting node_modules and running npm ci again.
  • For benchmark issues, ensure you have installed dependencies in the benchmarks/ folder.
