Full code :

• I'm trying to create an API that will read the YouTube data and write to me on my site that if that person is in the heart or not but it always gives me such a error

  var express = require('express'); var app = express(); var bodyParser = require('body-parser'); var request = require('request');

  //Configure app to use bodyParser();
  app.use(bodyParser.urlencoded({ extend: true}));
  app.use(bodyParser.json());
  
  var port = process.env.PORT || 1337;
  
  //Routes for the API
  var router = express.Router();
  router.use(function(req, res, next) {
      console.log("Got Request"); // -> Something is happening
      next();
  })
  
  var API_KEY= '';
  CHANNEL_ID = 'UCmDM6zuSTROOnZnjlt2RJGQ';
  router.get('/', function(req, res) {
  request.get('https://www.googleapis.com/youtube/v3/search', { part:         'snippet', channelId: CHANNEL_ID, type: 'video', eventType: 'live', key: API_KEY         }, function(data) {
      try {
          if(data['items'].length > 0) 
      res.json({status: true});
      }
        catch (err) {
            res.json({status: false});
            console.log(err)
      }
  });
  });
  
  //Custom URL e.g. example.com:1337/api/ECHO
  
  router.route('/:echo').get(function(req, res) {
  
      res.json({echo: req.params.echo});
  })
  
  
  
  //All routes will be prefixed with /api
  app.use('/api', router);
  
  
  //Start the server
  app.listen(port);
  console.log('API server has been started on port ' + port);

The error is on this line

if(data['items'].length > 0) 

The data object does not have a property of 'items'. Do a console.log of the data object to see what is returned. It looks like the Youtube API is not called correctly and returning an error instead.

Try the following code in your request instead:

request({url: "https://www.googleapis.com/youtube/v3/search?",
         qs:{ 
              part: 'snippet', 
              channelId: CHANNEL_ID, 
              type: 'video', 
              eventType: 'live', 
              key: API_KEY
            }
}, function(err, response, data){
    if (err){
      console.log(err);
    }

    console.log(data);
    if(data['items'].length > 0) {
        res.json({status: true});
    }
});
