multer VS formidable

Some basic examples of popular packages in the Javascript community include Express (a framework for building server applications) and Multer (a middleware for handling file uploads). These packages, when integrated into your project, can significantly streamline your development process.

Here are the docs for multer

You could use multipart/form-data https://github.com/expressjs/multer

multer - Middleware for Express.js to handle file uploads

busboy is what many Express middleware's such as multer use under the hood.

Maybe multer or validate-image-type?

Multer has some functions used to determine what type of file(s) to expect from the API request. Here we have used the 'multer.single("file")' function to let multer know that we're expecting a single file. (The full multer documentation can be found here).

You need something that can parse formData stuff. Like multer https://github.com/expressjs/multer

Instantiate a multipart/form-data parser using a library called formidable

import formidable from 'formidable'; /** * @see https://nuxt.com/docs/guide/concepts/server-engine * @see https://github.com/unjs/h3 */ export default defineEventHandler(async (event) => { let body; const headers = getRequestHeaders(event); if (headers['content-type']?.includes('multipart/form-data')) { body = await parseMultipartNodeRequest(event.node.req); } else { body = await readBody(event); } console.log(body); return { ok: true }; }); /** * @param {import('http').IncomingMessage} req */ function parseMultipartNodeRequest(req) { return new Promise((resolve, reject) => { /** @see https://github.com/node-formidable/formidable/ */ const form = formidable({ multiples: true }) form.parse(req, (error, fields, files) => { if (error) { reject(error); return; } resolve({ ...fields, ...files }); }); }); }

https://www.derpturkey.com/node-multipart-form-data-explained/ Here's a pretty in depth tutorial that explains the data, and how you can parse it using a third party library.

For the body-parser implementation, we'll use formidable npm module:
