How to upload a file to api server in node js?

I’m building an API using Node.js, and I need users to be able to upload files, like images or documents.i don't know how to do this, I ’ve heard of tools like Multer for handling file uploads, but I’m not sure how to set it up or handle different types of files. I’m also  want to know about validating the files and storing them safely on the server. If someone could help me with  basic example of how to upload a file to a Node.js API, I’d really appreciate it
