typescript-starter: A Scaffolding CLI That Puts Project Plumbing Before Code

What This CLI Actually Sets Up

typescript-starter solves the problem of boilerplate for a TypeScript library or Node.js project. Instead of manually creating tsconfig.json, test configuration, coverage tooling, documentation generation, and linting rules, you run one interactive command and the CLI generates a project with all of that wired together. The README lists the pieces: ESNext features via TypeScript, module exports for tree-shaking, type declarations, CommonJS backwards compatibility, AVA for tests, nyc for coverage, TypeDoc for API docs, and typescript-eslint with Prettier for linting and formatting. The target user is someone who wants a production-ready foundation without spending a day assembling tools that already work well together. The CLI is the primary interface; you only fork or clone the repo if you want to contribute to the starter itself.

The Workflow It Encodes: Watch, Test, Fix, Doc, Release

The README describes a development loop built around two watch tasks. You run `npm run watch:build` in one terminal and `npm run watch:test` in another. The build watch compiles TypeScript, and the test watch runs AVA against the compiled output. Only changed files are rebuilt and retested, which keeps the loop fast for larger projects. This is a TDD-friendly setup: you write a failing test, then implement the feature, and the watcher picks up the change. For maintenance, `npm run fix` runs ESLint and Prettier auto-fixes. `npm run cov` generates a source-mapped HTML coverage report and opens it in the browser. `npm run doc` generates TypeDoc HTML, and `npm run doc:publish` pushes it to GitHub Pages. The release process is also scripted: `npm run version` bumps the version, updates CHANGELOG.md, and tags the release using standard-version. The whole thing is a coherent pipeline, which is more than most scaffolding tools offer.

Getting Started: One Command, Then Interactive Prompts

The README's start command is simple: `npx typescript-starter`. This requires Node v10 or later. The CLI is interactive, so it asks you questions about the project you want to create and then configures everything. There is no mention of a non-interactive mode or flags for automation, so you cannot script the generation in CI or in a batch. After generation, you get a project with the scripts mentioned above. The default tsconfig.json is described as 'very flexible,' meaning it has many options commented out. The README recommends reviewing commented-out lines for stricter type checking, especially for large or mission-critical projects. That is a notable design choice: the starter prioritizes getting you up and running without warnings, at the cost of weaker type safety by default.

The Flexible Default tsconfig Is a Double-Edged Sword

The default tsconfig.json is intentionally loose. The README says this is 'to make getting started easier' and to avoid many TypeScript warnings. That means a new project might not catch type errors that a stricter config would. The README explicitly recommends enabling additional type checking features for 'mission-critical or large projects,' but it does not list which options to enable. You have to read the commented-out lines yourself. This is a real limitation: the generated project is not type-safe out of the box. For a library, that could mean shipping type declarations that are less precise than they could be. The trade-off is understandable for a starter, but it shifts the responsibility onto the user to harden the config later. If you want strict mode from the first commit, you will need to edit tsconfig.json immediately.

Documentation Generation Without JSDoc Noise

TypeDoc generates API documentation from TypeScript source. The README notes that you do not need to maintain a mess of JSDoc tags, because TypeScript types are tracked by the compiler. This is a genuine advantage over tools that require extensive comment annotations. The `npm run doc` command produces HTML and opens it in a browser. There is also `npm run doc:json` for generating a JSON export, which you can feed into a custom theme or a documentation build pipeline. The `doc:publish` command pushes to GitHub Pages, giving you a public docs site with one command. The README references the project's own GitHub Pages as an example. For a library, this is a low-friction way to keep docs in sync with the code, as long as you remember to run it on each release.

Release Management and Commit Tooling

The README recommends installing commitizen globally with `npm install -g commitizen` and then using `git cz` for commits. This integrates with conventional changelog and standard-version. The `npm run version` script runs standard-version to bump the package version, update CHANGELOG.md, and create a git tag. This is a complete release pipeline, which is helpful for libraries that need semantic versioning. The README also mentions a tool called `wip` for managing work-in-progress commits, but it does not explain how to use it. The reliance on global installs for commitizen is a minor friction point; a local dev dependency would be more reproducible. Still, the release workflow is a concrete benefit: you get changelog generation and tagging without setting up a separate release tool.

Maintenance Status and the Wrong Tool Scenarios

The repository has no recent releases listed, and the last push date is unknown. The README itself is from an era when Node v10 was current, which suggests the project may not have kept up with the latest TypeScript or tooling versions. That is a significant concern for a scaffolding tool, because generated projects inherit dependency versions and config patterns. If the underlying tools (AVA, TypeDoc, ESLint) have moved on, the generated config might be outdated. This makes typescript-starter a poor choice if you need a setup that reflects current best practices or if you plan to use a non-AVA test runner. It is also not suitable for projects that require a strict tsconfig from the start, since the default is loose. For a monorepo or a project with complex build requirements, a more flexible tool like create-ts-lib or a manual setup would be better.

Alternatives and What to Verify Before You Run npx

A direct alternative is `create-ts-lib` (a different CLI), which also scaffolds a TypeScript library but typically generates a stricter tsconfig and uses a different test runner or build tool. The key difference is that create-ts-lib often defaults to strict mode and may not include the same integrated documentation and release pipeline. Another option is to use `tsdx`, which is a zero-config tool for libraries that uses Rollup for bundling and has its own test setup. The difference in approach is that tsdx focuses on the build output and bundling, while typescript-starter covers the entire development lifecycle including docs and releases. Before running `npx typescript-starter`, verify that the generated project's dependency versions are current, and inspect the tsconfig for the commented-out strict options. Also check whether the CLI supports a non-interactive mode if you need automation, since the README does not mention one.

Editorial conclusion

Adopt typescript-starter if you are starting a new TypeScript library and want a working setup for AVA tests, nyc coverage, TypeDoc, ESLint, Prettier, and standard-version without writing config files yourself. Skip it if you need a strict tsconfig from the start, if you prefer a different test runner, or if you want a project that is actively maintained with recent releases. Before adopting, verify the generated project's dependency versions and the state of the default tsconfig, since the flexible default may hide type errors that a stricter config would catch.
