Building and testing your code

In this recipe, we will create a simple Continuous Integration (CI) pipeline that builds and validates code and gets integrated into pull request validation. We’ll use this code in subsequent recipes – that’s why we’re using a very simple JavaScript package.

Getting ready

I think it is best to build a new repository and npm package from scratch. Even if you’re not familiar with JavaScript, this should not be a challenge. You can compare your code or copy it from the following repository: https://github.com/wulfland/package-recipe. If you struggle with this, just clone this repository and work with it.

2. Clone your repository locally or open it in Codespaces.
3. Run the following command:

   $ npm init

   Follow the wizard. The name of the package...
