Developers' corner - MQTT example

  • Javascript
      client = mqtt.connect({host: 'localhost'});
    // Sending a volatile message
    client.publish('Kuzzle/request', JSON.stringify({
      index: 'index',
      collection: 'collection',
      controller: 'realtime',
      action: 'publish',
      requestId: 'some unique ID',
      body: { some: "message" }
    // Getting Kuzzle's response
    client.on('message', (topic, raw) => {
      const message = JSON.parse(Buffer.from(raw));
      // API results topic
      if (topic === 'Kuzzle/response') {
        // Response to our "publish" request
        if (message.requestId === 'some unique ID') {
          console.log('Message publication result: ', message);
