My doubts: - If a great amount of my functionality isn't covered by the directives - say my app does the bulk of interactions with Raphael.js instead of forms/checkboxes - is Angularjs still worth to include, or should I go with something lighter? - (similar) If I'm going to use a lot of jQuery plugins or external libraries, say jPlayer + D3.js + jQuery File Upload, etc - is Angular gonna get in my way when using them? In other words, would you write those frontends with AngularJS?
