15. Example: Mustache Templates

16. Example: jQuery for Cross Domain Reqs

17. Let’s Do It!

18. Tools: API Masher Visualization Engine: https://github.com/jcleblanc/api-masher Technology Backbone – ql.io – jQuery – Mustache Templates

20. Node.js: Installing the Package npm install ql.io-engine

21. Node.js: Including the Engine var Engine = require('ql.io-engine'); var engine = new Engine({ … });

22. Node.js: Invoking the Engine var script = "select * from …"; engine.execute(script, function(emitter){ emitter.on("end", function(err, res){ console.log(res['body'][0]); }); });

23. Tools: External API Tables Tables Source: https://github.com/jcleblanc/ql.io-tables https://github.com/ql-io/ql.io- site/tree/master/tables
