What is busboy?

The busboy npm package is a Node.js module for parsing incoming HTML form data, particularly file uploads. It is a stream-based parser that can handle multipart/form-data, which is primarily used for uploading files via HTTP.

What are busboy's main functionalities?

File Upload Parsing

This code sample demonstrates how to use busboy to parse file uploads from an HTML form. When a file is received, it logs the file details and the amount of data received.

const Busboy = require('busboy');
const http = require('http');

http.createServer((req, res) => {
  if (req.method === 'POST') {
    const busboy = new Busboy({ headers: req.headers });
    busboy.on('file', (fieldname, file, filename, encoding, mimetype) => {
      console.log(`File [${fieldname}]: filename: ${filename}, encoding: ${encoding}, mimetype: ${mimetype}`);
      file.on('data', (data) => {
        console.log(`File [${fieldname}] got ${data.length} bytes`);
      }).on('end', () => {
        console.log(`File [${fieldname}] Finished`);
      });
    });
    busboy.on('finish', () => {
      console.log('Done parsing form!');
      res.writeHead(303, { Connection: 'close', Location: '/' });
      res.end();
    });
    req.pipe(busboy);
  } else {
    res.writeHead(404);
    res.end();
  }
}).listen(8000, () => {
  console.log('Server listening on port 8000');
});

Field Parsing

This code sample shows how to use busboy to parse non-file fields from an HTML form. It logs the name and value of each field received.

const Busboy = require('busboy');
const http = require('http');

http.createServer((req, res) => {
  if (req.method === 'POST') {
    const busboy = new Busboy({ headers: req.headers });
    busboy.on('field', (fieldname, val, fieldnameTruncated, valTruncated, encoding, mimetype) => {
      console.log(`Field [${fieldname}]: value: ${val}`);
    });
    busboy.on('finish', () => {
      res.end('Done parsing form!');
    });
    req.pipe(busboy);
  } else {
    res.writeHead(404);
    res.end();
  }
}).listen(8000, () => {
  console.log('Server listening on port 8000');
});
