Instructor: 00:00 I'm going to use Express in node.js. First, we need to install Express package. Express package has installed successfully. Let me import the Express package. I'm going to create a new application from the Express class, now you can define here app.listen.
00:16 Basically, we need to specify the port. I'm going to choose 3000. You can also create a port variable. Let me create the port variable 3000. Now I can use this variable. I'm going to use adder function. If everything looks good so far, then we need to run this server. Server is running at port 3000.
00:39 Let me run the application by using NPM start. Incredible. Application is running at port 3000. Let me go to the local host column 3000. Oops, we don't have any route. Let me create a new route, app. inaudible . I'm going define a root route. It will take request and response.
01:00 I'm going to send a simple message, restart JSON, "Hello, GraphQL." Let me test it, boom. Here we have message, "Hello, GraphQL."
