Create a Simple Express Server

Now, let's write the basic structure of our server. Open your server.js file and add the following code:

• We import Express and CORS for building the API.
• We use express.json() and express.urlencoded() to parse incoming request bodies.
• The cors() middleware allows requests from any origin.
• We add a simple endpoint (/) that returns a message to confirm that the server is running.

Time to test our backend implementation. Run the server:

And visit http://localhost:3000 in your browser. You should see:

If you see this, congratulantions! your server is working correctly!
