{"library":"multer2","type":"library","category":null,"description":"Multer is a Node.js middleware specifically designed for handling `multipart/form-data`, primarily used for processing file uploads in web applications built with the Express.js framework. It efficiently parses incoming request bodies and populates `req.body` with text fields and `req.file` or `req.files` with uploaded files, depending on the configured upload strategy. Built on top of `busboy`, Multer focuses exclusively on `multipart/form-data` and will not process other form encodings. The current stable version is 2.1.1, released on March 4, 2026, with a consistent release cadence that includes frequent security patches. It is a widely adopted library within the Express ecosystem for file upload functionalities.","language":"javascript","status":"active","version":"1.1.1","tags":["javascript","form","post","multipart","form-data","formdata","express","middleware"],"install":[{"cmd":"npm install multer2","imports":["import multer from 'multer';","import multer from 'multer'; const storage = multer.diskStorage({...});","import multer from 'multer'; const storage = multer.memoryStorage();"]},{"cmd":"yarn add multer2","imports":[]},{"cmd":"pnpm add multer2","imports":[]}],"homepage":null,"github":"https://github.com/expressjs/multer","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/multer2","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/multer2/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Wed Jul 22","install_tag":null}}
