node.js - How could I upload files in ExpressJS 4.x

Question

I know there are something like multiparty, and busboy and formidable. I want to know is there any chance to upload files without them.

Answer 1

If you want to upload files you need to be able to parse multipart content. You can either use to parse it or implement your own. Here's a list the modules that can help you:

Direct parsing (in descending popularity based on Github stars as of Nov 2016):

• formidable
• busboy
• multiparty

Middleware:

• multer - based on busboy, much more popular than options below
• busboy middleware - last commit April 2014
• multiparty middleware - suggests not to use on Github page

Both:

• parted - last commit Jan 2015

If you want to write your own parser, you can have a look how above modules does it. Check these links also:

• multipart protocol spec and html spec

Happy coding.
