formidable form node js

// Step 1: Install the 'formidable' module using npm
npm install formidable

// Step 2: Require the 'formidable' module in your Node.js file
const formidable = require('formidable');

// Step 3: Create a new instance of the 'formidable' IncomingForm class
const form = new formidable.IncomingForm();

// Step 4: Parse the incoming form data in your HTTP request
form.parse(req, (err, fields, files) => {
  if (err) throw err;

  // 'fields' contains the form fields as key-value pairs
  console.log('Fields:', fields);

  // 'files' contains information about uploaded files
  console.log('Files:', files);
});

// Step 5: Set up event listeners for the form to handle various events
form.on('fileBegin', (name, file) => {
  // Event triggered when a file starts being received
  console.log(`File "${file.name}" is being uploaded.`);
});

form.on('file', (name, file) => {
  // Event triggered when a file has been successfully received
  console.log(`File "${file.name}" has been uploaded.`);
});

// Step 6: Set up the route or server to handle the HTTP POST request with the form data
app.post('/upload', (req, res) => {
  // Use the 'form.parse' method to parse the incoming form data
  form.parse(req, (err, fields, files) => {
    if (err) throw err;

    // Handle the form data as needed
    // ...

    // Send a response to the client
    res.send('Form data received and processed.');
  });
