What problem are you trying to solve?

Hello again. I have to resize(with sharp) image from formidable, how to get this? Should I save file before resize it?

All I want is here. parse req and resize immediately.

form.parse(req, (err, fields, files) => {
  Array.isArray(files.imgFile) ? resize.generateThumbnail(files.imgFile[0]) : resize.generateThumbnail(files.imgFile)
// 
})

Hey there again :)

There's no such thing as "original file" currently. The file is directly streamed/written to the file system in OS's temporary directory or the defined upload dir. From there you can do your thing.

In the future we will allow the users to directly access the buffer/stream of an incoming file, so Formidable will not even touch the file system and the users will be able to decide what to do with it.

The #360 kind of is about that.

So, in your case, you can get the file path from the files and move, resize, read and etc.

files.imgFile.path (or files.imgFile[0].path) contains the filename that was just saved.

If you don't want intermediate files, use options.fileWriteStreamHandler (which was introduced in #666) and construct a buffer. Then on('end') you can process the buffer with sharp.
