Prerequesties

Make sure your policy allows node js sdk and topics used by you.eg(topic is sensor here):

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "iot:Publish",
        "iot:Receive"
      ],
      "Resource": [
        "arn:aws:iot:ap-south-1:77********36:client/sdk-nodejs-*",
        "arn:aws:iot:ap-south-1:77********36:topic/sensor"
      ]
    },
    {
      "Effect": "Allow",
      "Action": [
        "iot:Subscribe"
      ],
      "Resource": [
        "arn:aws:iot:ap-south-1:77********36:client/sdk-nodejs-*",
        "arn:aws:iot:ap-south-1:77********36:topicfilter/sensor"
      ]
    },
    {
      "Effect": "Allow",
      "Action": [
        "iot:Connect"
      ],
      "Resource": [
        "arn:aws:iot:ap-south-1:77********36:client/sdk-nodejs-*"
      ]
    }
  ]
}

Assuming your thing name is thing1.
You will get files like root-CA.Crt , thing1.cert.pem, thing1.private.pem, thing1.public.key and start.sh .
Create a folder called files and put all above files(except start.sh) there.
Create a config.json (in the same folder as your code) mentioning below fields(easily find endpoint and client_id in start.sh) and file paths.eg:

{
    "endpoint":"a*************-ats.iot.ap-*****-1.amazonaws.com",
    "root_ca_cert":"files/root-CA.crt",
    "pem_cert": "files/thing1.cert.pem",
    "private_key":"files/thing1.private.key",
    "client_id":"sdk-nodejs-b*******-4***-4***-a***-1**********b"
}

Usage

import {create_connection,on_publish,publish} from 'aws_iot_js_simple'

async function connect(){
    const connection = await create_connection()
    await connection.connect();
    console.log("connected")
    await connection.subscribe('sensor', 1, on_publish);
    publish('sensor',connection,{'Temperature':23.5})
}
connect()

Warning

It will not work using require , you have to use ES6 module.
