cs-file-transfer-upload v2.0.5

cs-file-transfer-upload frontend

Description:

Module allows uploading multiple files in chunks. Use it if you need to pause your uploads. For backend you can use values from req.body like this:

let { slice, fileName, chunkNumber, numberOfChunks, size } = req.body;

Slice is base 64 encoded. You can also use npm module https://www.npmjs.com/package/cs-file-transfer-upload-backend

How to use:

Install:

npm i cs-file-transfer-upload

Import CSUpload to your main file:

import {CSUpload} from './node_modules/cs-file-transfer-upload/CSUpload'

Configure CSUpload:

CSUpload.config({
	'chunkSize': 5 * 1024 * 1024,	// size of a chunk in bytes, default is 1 * 1024 * 1024
	'concurrentRequests': 3,       // number of chunks sent at the same time (max value depends on browser), default is 1
	'url': 'http://localhost:3000/',	// server
	'repeat': true,	// if error happens retry, default is true
    	'repeatCount': 5	// if error happens retry 5 more times
})

Upload file:

singleFile = CSUpload.upload(file)	
// upload function returns singleFile object, a file currently uploading
// you can also add another argument, url that overrides the previously set url

singleFile functions:

singleFile.pause()	// pauses upload of a file
singleFile.continue()	// continues upload of a file

Progress listener:

singleFile.eventEmitter.on('progress', (progress)=>{
	// do something
})

Error listener:

singleFile.eventEmitter.on('error', (message)=>{
	// do something
})

Use webpack to bundle your files:
