@ngtools/webpack v1.2.9 doesn't produce factories for lazy routes

[Reuvenc]

Hi,

Updating to version 1.2.9 from 1.2.8 broke lazy loaded components using routes.
In the previous version, webpack produced separate chunk for each lazy route as expected.
In the current version, same process didn't produce the chunks.

OS?

Mac OSX (Sierra)

Versions.

@ngtools/webpack v1.2.9

The log given by the failure.

Could you provide us with an example repo we can use to investigate?

[GiuseppePiscopo]

If it can be helpful in solving this (to my team it would be for sure) we have a mini sample project with angular 4.1.1, @ngtools/webpack 1.3.1, webpack 2.2.1, typescript 2.3.2. It currently builds fine but shows the dreaded Error: Cannot find module '../private/module.ngfactory'. when trying to browse to lazy loaded area (dubbed private in the sample).

That is not using full angular-cli, only @ngtools/webpack. The readme shows how to launch the usual npm commands. HTH

EDIT: At branch jit-entry-point there's also a version where the JiT entry point is used, instead of the AoT one coming from past ngc experience.

Having same problem, but got this with --prod flag or/with --aot flag

[filipesilva]

Thanks for reporting this issue. This issue is now obsolete due to changes in the recent releases. Please update to the most recent Angular CLI version.

If the problem persists after upgrading, please open a new issue, provide a simple repository reproducing the problem, and describe the difference between the expected and current behavior.

[GiuseppePiscopo]

@filipesilva Just to get a better understanding: we have this same issue without using Angular CLI, just with ngtools/webpack 1.3.1. I got that angular team solved the issue with a new Angular CLI version, but keeping the same ngtools/webpack. Does that mean the issue resides outside of ngtools/webpack ?

[filipesilva]

@GiuseppePiscopo I really can't tell at this point, it's better to open a new issue with updated versions so we can investigate.
