It’s the package manager for Node! It might stand for Nuturing Palpable Magnificence, according to their site, but it also might stand for something else. [Like Node Package Manager.]

Starting a project

npm init


Node inspector

Can be run with node --inspector-brk <your file here>

When this runs, we will go to chrome:inspect to attach to the node process. We will then have full debugging tools.

You can install jasmine with this command in your project directory: npm install jasmine --save-dev

Using the example to get started

You should set up Jasmine as the test runner with npx jasmine init

You can set up the example Jasmine project with npx jasmine examples
