Features

Node.js, npm version

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.

TypeScript

Leverages esbuild for blazing-fast builds but keeps tsc to generate .d.ts files. 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

Tests

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

Format & lint

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

Releasing

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)
