Please try to decompose your problem to small pieces. You can always take one of our simple examples and start prototyping. When you face the problem please describe your problem (what you're trying to achieve) and obstacles on your way (what exactly doesn't work). The upside are that you'll work with native non-minified js code (no angular required), you'll be able to produce a simple testcase when spot a problem, and at the end you'll only have to integrate it in your angular app (or whatever framework/lib you work with).
We also offer our professional services.
