Example in the readme is confusing

The following line:

fd.append('file-upload', new File(['abc'], 'hello-world.txt'))

I thought I would stream the file hello-world.txt

• FormData can't accept a stream
• FormData can only accept 3 things... String, Blob and File
• FormData Also needs to be able to calculate the total content-length in adv, so that's why it only accepts file & blobs with a known size property.

so the way you would actually stream a file is that you would somehow get a File class from the filesystem that would stream the file for you.

the file class itself has a File.prototype.stream() method that we will call to read the file

---

so you wouldn't actually stream the file into a formdata, we read the data for you...

NodeJS is plaining on implementing a method to get Blob/Files from the filesystem somehow but in the meantime you would need something like: https://github.com/node-fetch/fetch-blob#blob-part-backed-up-by-filesystem

[jimmywarting]

The File class is also constructible, so you can create files in memory

Thanks for the details
