How to implement AWS IoT(device) in React-Native?
I figured this out,
Step 1: Install aws-iot npm package npm install --save aws-sdk aws-iot-device-sdk
Step 2: Install the nodeify package npm install --save-dev rn-nodeify
Step 3: Run this command to install series of packages specified
npx rn-nodeify --install "fs,util,path,tls,stream,buffer,global,process" --hack
"Please wait until the all the packages are installed"
Step 4: Goto package.json -> in scripts
section add,
"postinstall": "rn-nodeify --install fs,util,path,tls,stream,buffer,global,process --hack"
Step 5 : Install the asyncstorage-down package npm install --save asyncstorage-down
Step 6: rn-nodeify will auto-generate a file shim.js
in the root part of your react-native project. Just import it in index.js
file like this import './shim'
Finally, you are ready to use your aws-iot
package !!!
It is advisable to generate the iot-session keys as specified in the question above using REST API's in the backend.
I've read this post and the chat log, but have been unable to find a solution for this issue which I also seem to have. I have followed all the steps described here by Ron, but I get a filesys.existsSync is not a function error. I have included shim import as first code line in index.js. The code for communicating with AWS is as follows.
/**

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View} from 'react-native';
import AwsIot from 'aws-iot-device-sdk'
const instructions = Platform.select({
ios: 'Press Cmd+R to reload,\n' + 'Cmd+D or shake for dev menu',
android:
'Double tap R on your keyboard to reload,\n' +
'Shake or press menu button for dev menu',
});
type Props = {};
export default class App extends Component<Props> {
constructor(props){
super(props)
this.connectToIoT()
}
connectToIoT(){
var device = AwsIot.device({
keyPath: './cert/mykey-private.pem.key',
certPath: '/cert/mycert-certificate.pem.crt',
caPath: './cert/AmazonRootCA1.pem.key',
clientId: 'myclientid',
host: 'myhost'
});
console.log(device)
device
.on('connect', function() {
console.log('connect');
});
device
.on('message', function(topic, payload) {
console.log('message', topic, payload.toString());
});
}
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>Welcome to React Native!</Text>
<Text style={styles.instructions}>To get started, edit App.js</Text>
<Text style={styles.instructions}>{instructions}</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
Any possible solutions, or other methods of communicating with AWS IoT using MQTT in react native when using certificates for authentication?
