Run the basic npm scripts
In this lesson we will examine two common scripts (start and test) that npm natively understands. We’ll define these scripts for our existing repository and show how you can run the scripts from the terminal.
Instructor: [00:00] Let's replace the test command that npm generated for us. We will say, "mocha." We'll provide the spec folder. Then we'll require babel-register, which will automatically compile our tests, since we're using Babel for ES2015 and beyond.
[00:18] We could open up our terminal and type "npm test" or just "npm t" to run our tests. We can see that all our tests passed.
[00:27] Let's go back and add a start script, which is another script that npm recognizes natively. For our start, we'll have it kick off the main entry point of our app, which is index.js.
[00:39] If we go back to our terminal, since this is a script that npm understands, we can just say, "npm start." Our program will execute as expected. If we look at our files, we'll see that, sure enough, the data.json was generated. We can inspect that just to make sure.
