I’ll take you through the step-by-step to learn how to develop and publish a TypeScript NPM package. We’ll start by developing a very simple npm package using TypeScript. We’ll also cover unit testing, test coverage and code analysis

Ever wondered how to publish your very own npm package to the npmjs.com registry? In this article, I’ll take you through the step-by-step process. We’ll start by developing a very simple npm package using TypeScript. Next, we’ll add unit tests to confirm the accuracy of the functionality we’re developing and while we’re at it, we’ll also produce a test coverage report. After that, we’ll use static code analyzers to help us improve our code quality. Finally, we’ll make use of some command-line magic to publish this package to npmjs.com. Doesn’t that sound exciting? Let’s begin.

Note: The steps below are mentioned in a linear fashion for brevity. In reality, you might find yourself doing things iteratively — and that’s okay.

• Step 1: Develop
• Step 2: Adding some tests
• Step 3: Code analysis
• Step 4: Housekeeping
• Step 5: Publish
