About This Page

This page is a technical record of the skills, tools, and engineering practices represented in the npm TypeScript Package Template project.

Project Overview

The npm TypeScript Package Template is a starter repository for authoring and publishing TypeScript packages to npm. The project is maintained at blwatkins/npm-typescript-package-template and built with TypeScript and tsdown.

At a Glance

  • Project Type: Reusable project template / starter for npm packages
  • Primary Language: TypeScript
  • Primary Runtime: Node.js
  • Build Pipeline: tsdown
  • Quality Controls: ESLint
  • Automation: GitHub Actions
  • Dependency Automation: Dependabot
  • Security Analysis: CodeQL via GitHub Actions
  • Documentation Pattern: TypeDoc and Jekyll (GitHub Pages)

Skills and Tooling Inventory

Capability Record

  • Uses explicit package export and type declaration mappings to improve compatibility for ESM consumers and TypeScript tooling.
  • Applies strict TypeScript compiler settings and type-aware lint rules to improve early detection of implementation defects.
  • Automates lint, build, and test checks in GitHub Actions to improve change reliability before merge and release.
  • Produces API documentation and publishes a docs site workflow to improve discoverability and maintenance of project knowledge.
  • Runs CodeQL and Dependabot automation to improve baseline security and dependency hygiene over time.

Detailed Technical Notes

Each technical claim below is backed by a source link to the corresponding implementation or workflow configuration in the project repository.

ESM package contract and artifact layout

The package is configured as ESM and publishes built artifacts from _dist, including declaration files and a scoped export map. The build pipeline generates those outputs from src/index.ts using tsdown.

Evidence:

Utility module composition and re-export boundaries

The public entry point re-exports domain modules, and each domain module re-exports dedicated types and classes. This keeps the package API small while still allowing clear internal organization by domain.

Evidence:

Strict typing and lint enforcement model

TypeScript is configured with strict checks, including implicit-type and unused-code protections, to enforce predictable typing behavior. JavaScript and TypeScript lint configurations apply recommended and stricter rule sets for syntax safety and style consistency.

Evidence:

CI verification gates

Lint, build, and test scripts are wired into local and CI workflows via package.json. The primary CI workflow runs npm ci, lint, build, and tests across supported Node.js release lines before changes are accepted.

Evidence:

Documentation generation and GitHub Pages publishing path

API docs are generated with TypeDoc, while the documentation site is built from docs/ using a Jekyll workflow and deployed to GitHub Pages. Release-specific docs are stored under a versioned directory structure in docs/releases/....

Evidence:

Security scanning and dependency update automation

Security analysis is automated with a dedicated CodeQL workflow covering Actions and repository code languages. Dependency updates are automated with Dependabot for npm, GitHub Actions, and Bundler ecosystems, and package publishing uses trusted publishing permissions.

Evidence:

Current Gaps / Future Improvements

  • The template ships only an example HelloWorld module; real package logic is intentionally left to the consumer.
  • Release documentation under docs/releases/ is organized and maintained manually, with no automated changelog or release-notes generation.
  • Automated tests cover only the example module and are meant as a starting pattern rather than comprehensive coverage.
  • Publishing is triggered manually; there is no fully automated release-on-tag pipeline by design.
