🏃🏽 Instant Value: All basic tools included and configured:

  • TypeScript 5.5
  • ESM
  • ESLint with some initial rules recommendation
  • Vitest for fast unit testing and code coverage
  • Type definitions for Node.js
  • Prettier to enforce consistent code style
  • NPM scripts for common operations
  • EditorConfig for consistent coding style
  • Reproducible environments thanks to Volta
  • Example configuration for GitHub Actions
  • Simple example of TypeScript code and unit test

🤲 Free as in speech: available under the APLv2 license.

Getting Started

This project is intended to be used with the latest Active LTS release of Node.js.

Additional Information

Why include Volta

I recommend to install Volta and use it to manage your project's toolchain.

Volta’s toolchain always keeps track of where you are, it makes sure the tools you use always respect the settings of the project you’re working on. This means you don’t have to worry about changing the state of your installed software when switching between projects. For example, it's used by engineers at LinkedIn to standardize tools and have reproducible development environments.

Why Vitest instead of Jest

I recommend using Vitest for unit and integration testing of your TypeScript code.

In 2023, my team and I gradually switched from Jest to Vitest in all the projects. We've found out that generally, Vitest is faster than Jest, especially for large test suits. Furthermore, Vitest has native support for ES modules, is easier to configure, and has a much nicer developer experience when used with TypeScript. For example, when working with mocks, spies and types.

Nevertheless, the choice of specific tooling always depends on the specific requirements and characteristics of the project.

ES Modules

This template uses native ESM. Make sure to read this, and this first.

If your project requires CommonJS, you will have to convert to ESM.

Please do not open issues for questions regarding CommonJS or ESM on this repo.
