Just read or also write it to somewhere?
There are various ways to read the body. For small files you could just do:

const {buffer} = require('micro');
...
const data = await buffer(req);

I wanna upload them to s3, but when I try to fs.writeFile(fileName, buf, err => console.log(err)) file is broken

Just want to know that anyone contribute to this repo

@ozgreat Micro is designed to be minimal and simplistic. You either need to write your own modules or use community modules.

You mention you do not want to use micro-upload ? You do not mention why you do not want to use this. Maybe as you expect a posted binary file?

I know that the currently published micro-upload is old and fails npm audits. The repo has a dependabot branch that alleviates this, easily defined in package.json..

For your use case...

• Expect an uploaded file (multipart): You would have to write an upload module that would expect a file upload and pipe the data to s3.. maybe you could make a micro-upload-to-s3 module ?
• Expect posted binary data: then you would have to pipe the data yourself to s3. See also node IncomingMessage documentation.
