03 - Postman set up

In this module, we'll start to use Postman to test our application.

Adding a Response

Let's use Postman to start testing our server by following these steps. Please know that a little bit of the code will be explained in future modules. Right now, we just want to get used to using Postman:

1. Go into the directory with app.js and enter the nodemon app.js command to start the server. Leave it running.

2. Let's go into the app.js file. Add the code below to the bottom of the file:

   app.use('/api/test', function(req, res){
    res.send("This is data from the /api/test endpoint. It's from the server.");
   });

3. Again, we'll talk about the code soon. Keep the server running for now.

4. Open up Postman.

5. Choose File -> New -> Request.

6. In the request view, choose GET from the dropdown.

7. Enter the following url in the url input field:

   http://localhost:3000/api/test

8. Click send.

9. You should see the following result in the Postman response window:
