22. And now in Node.js
23. predictionio-client npm install
24. var p = require(‘predictionio-client') p.config.APP_KEY = ‘…’; p.config.APP_URL = ‘http://localhost:8000'; p.user.createUser(‘florian’, function() {}); p.item.createItem(‘game of thrones’, 'show', function () {}); p.action.like(‘florian’, ‘game of thrones’, function() {}); p.engine.recommendedItems('itemrec', ‘florian’, 5, function (a,data) { console.log(data); });
