Multipart-POST Request Using Node.js

Here, I introduce 2 scripts for uploading files to Slack using Node.js as samples. These 2 sample scripts are for uploading files to Slack.

You can upload the zip file by converting byte array as follows.
- At first, it builds form-data.
- Adds the zip file converted to byte array and boundary using Buffer.concat().
- This is used as body in request.

	docker rm $(docker ps -a -q)
	docker rmi $(docker images -q)
	docker volume rm $(docker volume ls \|awk '{print $2}')
	rm -rf ~/Library/Containers/com.docker.docker/Data/*


	function randomInt (min, max) {
	const range = max - min
	if (range < 0) {
	throw Error('cannot generate random int with min-max range less than 0')
	}
	const r = Math.random()
	return Math.round(r * range + min)
	}

	require('dotenv').config()
	const fetch = require('node-fetch')

	async function sendWebexFile ({
	filename = 'test.csv',
	fileMetaName = 'files',
	contentType = 'text/csv',
	content,
	metadata = {}
	}) {

	const crypto = require('crypto')

	// create hash of user sub, and append it to the first 8 characters of the user sub
	function getHash (sub) {
	const hash = crypto
	.createHash('shake128', {outputLength: 6})
	.update(sub, 'utf-8')
	.digest('base64')
	// you could remove this replace statement if you didn't want to alter the base64 or number of output characters
	// this is here so that only alphanumerics are returned. but it does change the length of some hashes (consistently)

	proxy_set_header Connection "upgrade";

	# this would set it to "main"
