What is @types/multer?

The @types/multer package provides TypeScript type definitions for Multer, a node.js middleware for handling multipart/form-data, primarily used for uploading files. It allows developers to use Multer in TypeScript projects with type checking, enabling better development experience and error handling.

What are @types/multer's main functionalities?

File Upload

This feature allows for the uploading of files. The code sample demonstrates how to set up a simple file upload endpoint using Express and Multer, where files are saved to the 'uploads/' directory.

import express from 'express';
import multer from 'multer';

const upload = multer({ dest: 'uploads/' });
const app = express();

app.post('/upload', upload.single('file'), function (req, res) {
  console.log(req.file);
  res.send('File uploaded successfully.');
});

Multiple Files Upload

This feature supports the uploading of multiple files in a single request. The code sample shows how to configure an endpoint to accept a maximum of 5 files using the `upload.array` method.

import express from 'express';
import multer from 'multer';

const upload = multer({ dest: 'uploads/' });
const app = express();

app.post('/upload', upload.array('files', 5), function (req, res) {
  console.log(req.files);
  res.send('Files uploaded successfully.');
});

File Filtering

This feature allows for filtering files based on specific criteria, such as file type. The code sample demonstrates how to accept only JPEG files using a custom file filter.

import express from 'express';
import multer from 'multer';

const fileFilter = (req, file, cb) => {
  if (file.mimetype === 'image/jpeg') {
    cb(null, true);
  } else {
    cb(new Error('Only JPEG files are allowed!'), false);
  }
};

const upload = multer({ dest: 'uploads/', fileFilter });
const app = express();

app.post('/upload', upload.single('file'), function (req, res) {
  res.send('File uploaded successfully.');
});
