Hi everyone, I am trying to upload a file using fetch streams, I need can
calculate the upload progress.
But on the server I receive an corrupt file of 0 bytes, I really don't know
how to use well the ReadableStreams feature, that is a really new feature
for me.
Client (Browser)
const fileReadble = (reader) => new ReadableStream({
start(controller) {
return pump()
function pump() {
return reader.read().then(({ done, value }) => {
if (done) {
controller.close()
return
}
controller.enqueue(value)
return pump()
})
}
}
const uploadVideo = async (file) => {
const fileReader = file.stream().getReader()
const response = await fetch('http://localhost:3005', {
method: 'POST',
body: fileReadble(fileReader),
})
if (!response.ok) {
console.error(`unexpected response ${response.statusText}`)
return
}
}
})
Server (Node)
import http from 'node:http'
import { createWriteStream } from 'node:fs'
http
.createServer((req) => {
if (req.method !== 'POST') return
req.pipe(createWriteStream('./video.mp4'))
})
.listen(3005)
