In this lab, we are going to build a simple node server that can post a new message and resrespond with a list of messages.

As usualy, our development process here will follow the technique of test driven development. So you should begin by running the command: npm test. You should see an error becuase we've not yet installed the mocha testing library. Let's do that now:

npm install mocha --save-dev
npm install mocha-multi --save-dev
npm install chai --save-dev

Now when you run npm test, you should see that the tests are running, and one test for "has the correct devDepenencies" should be passing.

At this we need to intall the other necessary depednencies. You should be familiar with this process from the previous npm lab, so let's see if you can do it on your own. Remember that the tests in the /tests directory service as a specification for this project. Look there to see what packages you may need to install.

Steps:

1. Create a server file: server.js
2. Set up a simple hello world server
3. Install router

• npm init
  • npm install router --save
