node 10 form data

  1. First, we need to import the http module in Node.js to handle HTTP requests and responses. This can be done using the require keyword:
const http = require('http');
  1. Next, we need to create a server using the createServer method from the http module. This method takes a callback function as an argument, which will be triggered whenever a request is received:
const server = http.createServer((req, res) => {
  // Request handling logic goes here
  1. Inside the callback function, we can access the request data using the req object. To handle form data, we need to use the data event to collect all the chunks of data and concatenate them into a single string. We can do this using the on method of the req object:
let formData = '';

req.on('data', (chunk) => {
  formData += chunk;
  1. Once all the form data has been received, the end event will be triggered. We can then parse the form data into key-value pairs using the querystring module:
req.on('end', () => {
  const parsedFormData = querystring.parse(formData);
  // Process the form data here
  1. Finally, we need to send a response back to the client using the res object. We can set the appropriate header and write the response body using the writeHead and end methods:
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Form data received');
  1. To make the server start listening for incoming requests, we need to specify the port to listen on using the listen method:
const port = 3000;

server.listen(port, () => {
  console.log(`Server running on port ${port}`);

Note: Make sure to replace 3000 with the desired port number.

This is the basic outline of how to handle form data in Node.js using the http module. You can add more logic to process the form data according to your specific requirements.
