Lecture 350:- Uploading Files - How Does It Work
Uploading files refers to the process of transferring files from a client to a server over a network. When a user selects a file to upload from their local machine, the browser sends the file to the server using the HTTP POST method. The server then receives the file and can save it to disk or process it in other ways.
File uploads can be done using HTML forms with the enctype="multipart/form-data" attribute, which allows files to be uploaded along with other form data. The file data is encoded in a special format called MIME (Multipurpose Internet Mail Extensions) and sent to the server using the HTTP POST method.
On the server side, there are many ways to handle file uploads, such as using built-in Node.js modules like fs (file system) or third-party libraries like multer or busboy. These modules provide APIs to receive the file, handle any errors, and save it to disk or process it in other ways.
Overall, file uploads are an essential feature of many web applications, allowing users to share and store various types of data on a server.
