In order to get some experience with jsinterop I started wiring some libraries in a need to use basis. The libraries are requiring other libraries so until now I have __partial__ bindings for the following libraries:
1) jquery 2) DataTables 3) D3 4) Bootstrap - Modals 5) DateRangePicker 7) Moment Here are the lessons learned so far. 1) you need to do it in order to get the handle of it. I can't imagine this thing can be automated. There are too many pitfalls and way too many ways to do it. Somebody need to balance the pluses and minuses of every approach 2) this forum is really valuable (thanks Thomas, Jens). Without it I wouldn't have moved any further than the first 2-3 initial roadblocks. 3) There are still many rough spots and missing functionality. Some of the top of my head are a) Casting is logical but weird. You have to fight at the IDE/java level and then at the SDM level. It may produce difficult to understand runtime errors. With chrome and --preety you can understand what's going on through. b) Integers are weird. Doubles and String are mostly working... c) JavaScriptObject and JSNI and some util functions are still required for some functions d) Casting to/from JavaScriptObject is not obvious. Casting to other java primitive types may work except some times doesn't. e) Some semantics may suprise you like @JsType(isNative = false) requiring extra compile time flags. If you read the Q&A discussion it actually makes sense f) Javascript this is not supported without hoops g) Creating config objects out of strings is not trivial like in js. Some libraries are very keen to config objects DataTables being the prime example. 4) There is a question if we could somehow create a repository of jsinterop bindings? Someone mentioned http://http://jsinterop.xyz 5) Another question is how to use these bindings (that somebody else created)? I mean - if I only need only js binding - should I pay the price for several java js bindings just because they arepackaged together - or they are ignored thanks to the GWT compiler?
