generator-ts-np

Yet another yeoman generator for building npm packages with TypeScript.

TSNP stands for TypeScript Node Package 📦.

Install

Requires Node >=8.

Install yeoman first

npm i -g yo

Then install this generator from npm,

npm i -g generator-ts-np

From Github Package Registry. (Guide).

Usage

$ mkdir my-new-package # new dir
$ cd my-new-pacakge # go to the package dir
$ yo ts-np # use yeoman

Why

• No global dependencies.
• Written in TypeScript and when publishing, definition(.d.ts) will also ship with this package.
• Prettier and Eslint.
• Support for Github Package Registry and NPM
• Tests uses Jest (tests are also written in TypeScript)
• Pre-publish hook for build (so you never miss it)
• Automated build and deployments (using Github Actions) (eg: scope-prefixer package)
• Lint rules adopted from Google (which means higher coding standard)
• Publishes only the required files (less bundle size)

Directory Structure

$ yo ts-np command will ask you a few questions and generate the below structure.

• You write your typescript files in /src.
• Write their tests in /tests
• /src compiling creates /dist directory which is used for publishing

The generator produces following files.

Handy npm scripts

• npm test: 🌟 compiles typescript (npm run build) and run tests.
• npm run build: compiles src and tests files.
• npm run lint: runs eslint and prettier checks.

See other scripts and their uses

Automated Build 🧪 and Deployments ✅

• Continues integration: run tests when code pushed.
• Continues deployment: run tests and publish the package when a git release is published.

By default, this feature is disabled for convenience. You can enable it in a few steps 🍼.
