Which built-in module in Node.js is used to create a web server?httpfsurlpath

The built-in module in Node.js used to create a web server is the 'http' module. Here are the steps to create a web server:

1. First, you need to import the 'http' module. You can do this using the 'require' directive. Here is how you do it:

var http = require('http');

2. Next, you need to create the server. You can use the 'createServer' method for this. This method takes a function with two parameters, request and response:

var server = http.createServer(function (req, res) {
  // handle request and response here
});

3. Inside the function, you can write the response from the server. For example, you can write a simple text response like this:

res.write('Hello World!'); //write a response to the client
res.end(); //end the response

4. Finally, the server needs to listen on a port to check for incoming requests. You can use the 'listen' method for this:

server.listen(8080); //the server object listens on port 8080

So, the complete code to create a simple web server that responds with 'Hello World!' would be:

var http = require('http');

var server = http.createServer(function (req, res) {
  res.write('Hello World!');
  res.end();
});

server.listen(8080);

With this code, if you navigate to 'http://localhost:8080' in your web browser, you will see 'Hello World!' displayed.
