create-ts-module

A package initialization template for typescript modules.

npm init ts-module -y

This initializer is specifically designed to make TypeScript modules for npm installation. When you publish a module made with create-ts-module it will follow the TypeScript publishing recommendations and the pkg.module recommendation by adding "types": "es/index.d.ts" and "module": "es/index.js" in the package.json file.

build scripts

The generated module does not rely on any large build tool, rather it uses npm scripts. Try running npm run in your cli to see what is available to do. Here is a short summary:

• npm run clean: clean the output folders ./es and ./js.
• npm run tslint: lint the ts files
• npm run tsc: compile the TypeScript in ./ts into ES2015 in the ./es folder.
• npm run babel: compile the ES2015 in the ./es into JavaScript in the ./js folder.
• npm run compile: run both the tsc and the babel steps.
• npm run test: run unit tests.
• npm run watch: continuously run unit tests.

dev-dependencies

The generated package will have few dev-dependencies:

• typescript: Used to compile TypeScript to EcmaScript 2015
• @babel/*: A bunch of modules used to compile EcmaScript 2015 to JavaScript
• ava: A good and simple test runner

There are some other dependencies which are needed just to get this all to work.

peer-dependencies

There is one peer dependency, @babel/runtime, which is needed for running the JavaScript output. It is set as a peer dependency to minimize the output file size. If you use a bundler like webpack then you probably have this already.
