Basic Phase 1: Initialize an Express Application

In this phase, you will create a new Express project and initialize an Express application to listen for requests on a port. You will also return a simple text response on the /status route.

Create a new Express project

cd into the server directory after creating it.

Add a package.json file by running the following command:

npm init -y

Install the following dependencies using the command npm install:

• express

Install the following development dependencies using the command npm install -D:

• nodemon

Create an Express application

Create a file called app.js inside of your server folder.

Initialize an Express application inside that file.

Establish listener

Create a port variable and set it to a desired port for your Express application like 5000.

Allow the initialized Express application to listen for requests at the port you set to the port variable. Your application should log something like "Server is listening on port <port number>" when the server successfully connects to the port.

Add scripts to start the server

Create a script in the package.json file to start the server in production using node. The script can be named "start".

Create another script to start the server in development using the nodemon package. nodemon allows the server to automatically restart whenever any server files get updated. This script can be called "dev".

Test your server

Start your server in development using one of the package.json scripts.

Check to see if you set things up correctly by navigating to the appropriate URL for accessing the root URL for the Express server in the browser.

You should see the generic Express error message of Cannot GET / because you have not created a route handler for GET / yet.

Make route with text response

Create a route handler for the GET protocol at the route /status. Send a plain text response using res.send() with text like "The server is alive!".

Test your new route in the browser by adding /status after the port number in the address bar.

If all is working properly, your browser will show

The server is alive!
