Generator-jhipster: Angular production build failure with more than one lazy loading module

[shai2017]

dashboard.zip

Overview of the issue

Created another module named dashboard (very similar to "admin module" - structure wise). When importing this module at app.module level it works fine and production packaging working as expected.
But when using lazy loading in app-routing.module (exactly same as admin module). Dev (./mvnw and yarn start) is working fine and I am able to see everything is loaded as expected.
But production build keeps on failing to generate www package in target folder.
( ./mvnw -Pprod clean package -DskipTests=true)

Motivation for or Use Case

It is stopping to package the web application for production which I am deploying to google cloud using CI build

Reproduce the error

1) Build jhipster microservice gateway without any entity
2) create module dashboard under app folder (equal level as admin, core etc). I have attached the folder with code.
3) build process is successful but not generating www folder. please see log message.

Related issues

Suggest a Fix

it has something to do with webpack production build when using lazy loading ( used --progress flag in production build but not really helpful). When packaging is successful I am seeing it is emmitting and then displaying webpack assets and chunks. but in this scenario is it failing to do anything and going directly to $ rimraf target//www/app/{src,target/}

See logs of webpack build for production.

I am facing same issue with [email protected]

[deepu105]

@shai2017 this doesn't seem like a JHipster bug, it seems more like an issue with the custom code you added. Hence this should be in stack overflow, see our guidelines below. If you still think its a JHipster bug please do ask us to reopen. Also, check this, it might help

This is not a bug or feature request and hence this is not the correct forum for this.

[shai2017]

hi Deepu,

In my opinion this is the problem of Jhipster Webpack version conflict. It is not working when using Lazy loading of additional module. i have copied exactly admin module structure (bare minimum).

It is working fine in dev mode but not generating output folder in production mode.

[deepu105]

@shai2017 that doesnt make sense, if it was a JHipster config issue, how can the admin module work but not others. @wmarques what do you think?

[ruddell]

@deepu105 I was able to reproduce it (copied admin module to admin2 module and only kept gateway page). Webpack shouldn’t fail when adding a second lazy-loaded module. I couldn’t get any specific error message though

[wmarques]

Let me try to reproduce and analyze this. The lazy loading is handled by @ngtools

[mmaask]

Running into the same problem. Added another lazy loaded module and getting no production build output.

[pawprosk]

Only for reference I have similar problem with monolith application, everything works fine if there is no other lazy module defined in route - I’m not sure if first „lazy” module is loaded eager by angular thats why it deploys nice and easy - with multiple entities application starts to loading very slow so lazy modules in that situation should help a lot to avoid loading all entities on first page load.

[vishal423]

I had quick look and it's really weird. Even after enabling logs, don't see anything useful that can provide insight into such behavior.

[vishal423]

BTW, can someone update issue summary to something like 'Angular production build failure with more than one lazy loading module'

[pauloegk]

Hi everyone, I have the same problem, will this be fixed?

[deepu105]

This is being tracked and will be fixed at some point, but cant give a timeline since its OSS and someone needs to find time

[wmarques]

I can confirm the issue, I'm working on it... But as webpack is outputing literally 0 error even in verbose, it's going to be difficult to fix :(

[wmarques]

I created a sample repo to reproduce this: https://github.com/wmarques/jhi-lazy-fail
Just clone it, run yarn build and you will see the issue.
In dev mode it works, you can click on "user-management" and it will lazy load a dumb component I created just to test.
It seems to be related to https://github.com/angular/angular-cli/issues/8865, I'll comment this, hoping they know what is failing...

[wmarques]

I got something after disabling the HTMLWebpackPlugin... Seems to be the cause of the bug

[wmarques]

FINALLY FIXED THIS 🎉
Had to manually orders chunk in the HTMLWebpackPlugin, I don't know why it was broken, but it works, will provide a PR soon.

[pawprosk]

Tested fix - everything works like a charm now - Thank you @wmarques 🥇

[pauloegk]

Thanks @wmarques
