How to create and publish a TypeScript library with ease
For the reasons mentioned above, I created a TypeScript library template you can use as a starting point for your library. It is based on my experience and best practices from the TypeScript community (this is usually subjective), and it includes everything you need for developing, testing, documenting, and publishing your library. This article will explain what this template offers, how to use it, and how to customize it for your needs.
