Support for cafile certificates

[marktyers]

The server I use employs MQTTS and uses a certificate file. When I connect using mosquitto_sub I include the --cafile flag and pass my certificate file. Is this functionality supported in your tool?

[jdiamond]

The Deno client supports CAs. The equivalent of --cafile in Deno is an option called certFile (see Deno.connectTls) if you're constructing the Deno client in code. I need to work on the docs and add some examples.

Thanks for the reply.

Script throws 17 errors when running, I can't find the solutions in the documentation:

/* deno_sub.js */

import { Client } from 'https://deno.land/x/mqtt/deno/mod.ts'

const CAfile = await Deno.readTextFile('mqtt.crt')

const conf = {
	url: 'mqqts://mqtt.coventry.ac.uk',
	options: {
		host: 'xxx',
		port: 8883,
		protocol: 'mqtts',
		protocolId: 'MQIsdp',
		certFile: CAfile,
		username: 'xxx',
		password: 'xxx',
		secureProtocol: 'TLSv1_method',
		protocolVersion: 3
	}
}
const client = new Client(conf)

await client.connect()

await client.subscribe('iot/#')

client.on('message', (topic, payload) => {
  console.log(topic, payload)
})

These are the errors thrown.
