Creating an express router

- [Instructor] Since we have a few routes…for our message board API…and we will eventually have more for authentication,…let's create a router with express…that will allow us to separate and organize…our different routes.…We will make one router…for our general purpose web API routes…and eventually another for authentication specific routes.…Let's begin by going above our first route on line 14…and adding a new line…and let's create a variable called API…and set it to express.Router…and that will create a new router for us.…

At this point we can attach both our existing routes…our messages get and message post to our new API router.…So instead of app.get as we have on line 16…I will change that to api.get…and api.post on line 20…and the last thing we need to do…is to tell our express app to use our new router.…So at the bottom above our app.listen I'll create a new line…and add app.use…and pass in a base route for the first property…and I'll use /api meaning that in order to…access our routes now we'd have to go through /api /message…
