Angular2, AoT compilation: Cannot determine the module for component AppComponent

[musahaidari]

OS?

Windows 7

Versions.

C:\Users\wdd>node --version
v6.6.0

Summary: I am trying to use Angular2 AoT for my Angular2 application, but since I have static providers to pass some values from server to Angular2, ngc shows some errors. My problem is how to get the ngFactory files created using ngc.

Details: I am using the cookbook guide, and running "node_modules/.bin/ngc" -p tsconfig-aot.json shows me the below error:

Error: Cannot determine the module for component AppComponent!

Notes:

• I verified that if I remove code for static provider, that I used for passing data from servver to Angular2, i.e. createMainModule() in app.module.ts, and so on, then ngc works fine.
• I am using SystemJS as the module loader.
• I have posted the same on stackoverflow incase there is already a technique I do not know about, but it seems that is not the case and passing data from server to client (with the method I have used) and AoT is not possible.
• The method I have used to pass data from server to client is exactly used as explained in the official angular 2 docs, saying that, AoT should support it.

I had similar errors with lambdas. Converted them to ordinary functions, and errors gone.

[musahaidari]

@tsabirgaliev I have lambdas too, but when I remove the static providers, then it compiles too, even with lambdas.

This issue tracker is for issues related to angular-cli, not the AoT compiler in general. Stack overflow is the best bet for this sort of questions.
