To upload a file or image in Angular, use the ng2-file-upload  library to upload a file to the server. We use  Node.js  as a backend server. We install Angular 9  using Angular CLI  and then start working on this Angular File Upload demo . For managing the uploaded files at the backend, we use the multer library. Multer is a node.js middleware for handling multipart/form-data, which is primarily used for uploading files. It is written on top of the  busboy  for maximum efficiency. Multer will not process any form which is not multipart.
