Solution Review: Creating a Web Server

Explanation

• We start by requiring the built-in HTTP module in line 1.

• In line 3, we create a variable called server. This variable holds the logic for the createServer() method that enables us to create an HTTP server that gives a response back to the client. This is made possible by two methods: the res.writeHead() method and the res.end() method.

• The res.writeHead() method helps us to set the correct content type of ‘text/html’. This allows us to display HTML elements on the page.

• In line 6, the res.end() method takes in the HTML tags to be displayed on the browser and helps us end the response process.

• Finally, in line 20, we chain our function using the listen() method to work on port 5000.
