Node tutorial

This is a quick introduction to using JavaScript on the command line using Node.JS.

Testing what’ve done

There are some pre-written tests that will track your progress through this tutorial. To test that you have done the right thing you need to have the mocha module installed.

Install it by typing this into a terminal window:

sudo npm install -g mocha

The -g is for global package. That means you will be able to run mocha from the command line, from any directory.

You now need to:

• fork the Node-Tutorial repository
• clone a copy into your local projects folder
• open a new terminal window and change into the node-tutorial folder
• run mocha in that folder - type mocha and press enter - you should a message saying 0 passing (1ms)
• you should get messages about some failing tests
• all the work below should be done in the node-tutorial folder.

You can use the command below to see which tests are passing and which not:

mocha

As you work your way through the tasks run the mocha command after each test to be sure that your implementation is successful. As you work your way through the tutorial more and more of the tests should pass.

Hello terminal

Create a file called hello.js in the node-terminal folder, in the script write ‘hello world!’ to the console.

You can run the program from the command line using: node hello.js

Run mocha from the command line. At least one test should pass.
