minAWS - minimal AWS interface

This module is a minimal interface to AWS using SigV4 requests.

Currently it doesn't depend on anything other than nodejs v19.x or a current browser.

There's some sample code in the samples directory to see how to use it.

The code should be legible enough.

Getting Started

Let's say you have some AWS credentials (more on this in another repo) and you want to create a mqtt connection using Matteo Collina's excellent mqtt.js repo found on this here Github. You can do something like:

const mqtt = require('mqtt')
const { presign, credentials } = require('minaws')

const d = new Date()
const service = "iotdevicegateway"
const region = process.env["AWS_DEFAULT_REGION"]
const endpoint = process.env["AWS_IOT_ENDPOINT"]
const method = "GET"
const req = new Request(["wss://",endpoint,"/mqtt"].join(""), { method })

const main = async () => {
	const url = await presign(service,region,credentials(),d,0,"",req)
	const client = mqtt.connect(url)
	client.on("connect", () => {
		client.subscribe('#', (err) => {
			if (err) return err
			client.publish('hello','hello world!')
			client.on('message', (topic,message) => {
				console.log(message.toString())
				client.end()
			})
		})
	})
}
main()
