Hapi-MQTT

A very simple module that allows the usage of a common MQTT Client in Hapi.js

Options is an object with the arguments passed to MQTT.js

• brokerUrl: MQTT connection string (eg. mqtt://test.mosquitto.org)
• opts: See MQTT.js for full specs

The plugin expose:

• client: The MQTT Client

Usage example:

const Hapi = require('hapi');
const Boom = require('boom');

const mqttOpts = {
    brokerUrl: 'mqtt://test.mosquitto.org',
    opts: {
        username: 'myHapiService',
        password: 'aVerySecurePassword'
    }
};

async function start() {

const server = new Hapi.Server();

await server.register({
       plugin: require('hapi-mqtt'),
       options: mqttOpts
   });

    server.route( {
        method: 'POST',
        path: '/say',
        handler: async (request, h) => {
            const mqttClient = server.plugins['hapi-mqtt'].client;
            try{
                await mqttClient.publish('user/say','something');
            }
            catch (err) {
                return Boom.internal('Internal MQTT error',err);
            }
            return "something"
        }
    });

     // Start server
     try {
         await server.start();
     }
     catch (err) {
         console.log(err);
         process.exit(1);
     }
     
     console.log(`Server started at ${server.info.uri}`);
}
     
start().catch(function (err) {
    throw err;
});
