Angular-cli: build and ng serve really slow on aot , is there any solution ?

[jjlgjkkl]

I am using cli1.0.6 and angular4.0.3 and have developed 100+ lazy load modules.
when enabled aot,
ng serve --aot=true can cause more than 10 min
and even ng build --prod --aot=true spend more than 10 min

that means aot cannot be used both on dev and prod

is there any way can help me ?

As it is stated in the official documentation:

"_Today AOT compilation and tree shaking take more time than is practical for development. That will change soon. For now, it's best to JIT compile in development and switch to AOT compilation before deploying to production._"

So it's better to develop your app in jit.

I have the same question, how do you solve it

[vermadev95]

use "ng serve"
That should solve your problem

[vermadev95]

You can use this flag while compiling:
ng serve --source-map=false

It take 10sec to compile now while previously it was taking 32sec.
source-map is just used for debugging. So if not using debugger you can disable and compile.
