TypeScript Library Starter

Yet another (opinionated) TypeScript library starter template.

If you're looking for a backend service starter, check out my typescript-service-starter

Opinions and limitations

1. Relies as much as possible on each included library's defaults
2. Only relies on GitHub Actions
3. Does not include documentation generation

Getting started

1. npx degit gjuchault/typescript-library-starter my-project or click on the Use this template button on GitHub!
2. cd my-project
3. npm install
4. git init (if you used degit)
5. node --run setup

To enable deployment, you will need to:

1. Set up the NPM_TOKEN secret in GitHub Actions (Settings > Secrets > Actions)
2. Give GITHUB_TOKEN write permissions for GitHub releases (Settings > Actions > General > Workflow permissions)

Features

TypeScript Library Starter relies on Volta to ensure the Node.js version is consistent across developers. It's also used in the GitHub workflow file.

$3

Leverages Typescript 7 for blazing-fast builds and type-checking.
Generates a single ESM build.

Commands:

- build: runs type checking, then ESM and d.ts files in the build/ directory
- clean: removes the build/ directory
- type:check: runs type checking

$3

TypeScript Library Starter uses Node.js's native test runner. Coverage is done using c8 but will switch to Node.js's one once out.

Commands:

- test: runs test runner
- test:watch: runs test runner in watch mode
- test:coverage: runs test runner and generates coverage reports

$3

This template relies on Biome to do both formatting & linting in no time.
It also uses cspell to ensure correct spelling.

Commands:

- lint: runs Biome with automatic fixing
- lint:check: runs Biome without automatic fixing (used in CI)
- spell:check: runs spell checking

Under the hood, this library uses semantic-release and Commitizen.
The goal is to avoid manual release processes. Using semantic-release will automatically create a GitHub release (hence tags) as well as an npm release.
Based on your commit history, semantic-release will automatically create a patch, feature, or breaking release.

Commands:

- cz: interactive CLI that helps you generate a proper git commit message, using Commitizen
- semantic-release: triggers a release (used in CI)
