Current behavior Because ngc wraps tsc, it can only generate ngFactories for typescript files.

Expected behavior Ideally, typescript transpiling and ngFactory generation would be decoupled, so plain js (or languages other than ts that target js) can be used.

What is the motivation / use case for changing the behavior? AOT compilation and treeshaking are important tools for production deployment, and should work with all languages supported by angular.

• Angular version: 2.0.0

• Language: all

My apologies if this has been discussed before. I have been able to find no reference to this issue on SO, the google group, or in the issues (although github’s search does not scale well with 1000+ open issues).

Any update on this? Is it possible to use AOT with JavaScript/Angular 4?
