What is @types/busboy?

@types/busboy provides TypeScript definitions for the busboy package, which is a streaming parser for HTML form data for node.js. It is particularly useful for handling file uploads.

What are @types/busboy's main functionalities?

Parsing Form Data

This code demonstrates how to use busboy to parse form data, including file uploads, from an HTTP POST request.

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 ${data.length} bytes`);
      });
      file.on('end', () => {
        console.log(`File [${fieldname}] Finished`);
      });
    });
    busboy.on('field', (fieldname, val) => {
      console.log(`Field [${fieldname}]: value: ${val}`);
    });
    busboy.on('finish', () => {
      res.writeHead(200, { 'Connection': 'close' });
      res.end("That's all folks!");
    });
    req.pipe(busboy);
  } else {
    res.writeHead(404);
    res.end();
  }
}).listen(8000, () => {
  console.log('Listening for requests');
});

Handling File Uploads

This code demonstrates how to handle file uploads using busboy by saving the uploaded files to a specified directory.

const Busboy = require('busboy');
const fs = require('fs');
const path = require('path');
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) => {
      const saveTo = path.join(__dirname, 'uploads', path.basename(filename));
      file.pipe(fs.createWriteStream(saveTo));
    });
    busboy.on('finish', () => {
      res.writeHead(200, { 'Connection': 'close' });
      res.end('Upload complete');
    });
    req.pipe(busboy);
  } else {
    res.writeHead(404);
    res.end();
  }
}).listen(8000, () => {
  console.log('Listening for requests');
});

Other packages similar to @types/busboy

formidable

Formidable is a Node.js module for parsing form data, especially file uploads. It is similar to busboy in that it can handle file uploads and form data parsing, but it provides a higher-level API and more built-in features like file renaming and progress tracking.

multer

Multer is a middleware for handling multipart/form-data, which is primarily used for uploading files. It is built on top of busboy and provides a simpler API for handling file uploads in Express applications. Multer is more opinionated and easier to use for common use cases compared to busboy.

multiparty

Multiparty is a module for parsing multipart/form-data, which is used for file uploads. It is similar to busboy but provides a higher-level API and more features out of the box, such as handling multiple file uploads and field parsing.
