Current behavior

Hi I created a project with cli version 1.6.6 and i've work on this project about a month, always ng serve testing and today I've want to deploy on server and when I run 'ng build --prod' it throws 'Maximum call stack size exceeded...'
I look this post with likely behaviour and doesn't seem to be fixed :(

Expected behavior

It should complile without problems.

Minimal reproduction of the problem with instructions

[filipesilva]

This seems like a bug but we'll need to look at a reproduction to find and fix the problem. Can you setup a minimal repro please?

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

I agree https://github.com/angular/angular/issues/19979 is related but I can't say if it's the same thing. If you have a repro it will go a long way towards us identifying what's wrong.

[morganabel]

I was able to reproduce this bug or something very very similar. I have created a repo here.

Steps to reproduce:

1. ng new reprobug9636
2. cd reprobug9636
3. npm install --save @timkendrick/monaco-editor
4. Import and use Monaco editor in a component:

import * as monaco from '@timkendrick/monaco-editor';

let editor = monaco.editor.create(new HTMLElement(), {
      theme: "vs-dark",
      language: "csharp"
    });

1. Run ng build --prod

That gives the following output:

@morganabel - I get this error in my project occasionally. I've disabled the build optimizer for now.

[pranavneeraj]

I got this while building for production.

I get this running ng test as well

@filipesilva

Several people who uses ag-grid started getting this error after upgrading angular to v6.
https://github.com/ag-grid/ag-grid-angular/issues/184#issuecomment-389157855

Originally, I though it's ag-grid problem (maybe some circular dependencies) and started looking into it. Deleting line by line I ended up with one file which still causes this "max call stack reached" error.
I've checked it on several machines with windows 10 - failed on both.

To reproduce add that file in your project or just clone this repo and run ng build --prod.

You should get:

[filipesilva]

@dzonatan that is very interesting information, thank you for taking the time to identify what's breaking. Will look at it 👍

[filipesilva]

As far as I can tell it is a problem with build optimizer, since I can repro with ng build --aot --build-optimizer but not with ng build --aot.

[dzonatan]

Indeed with build optimizer, forgot to mention that too.

[dzonatan]

@filipesilva did you had chance to look at it? Or maybe have any tips how can I analyze build-optimizer myself in best way?

[filipesilva]

@dzonatan looked into this a bit today and I am sorry to report this looks like an existing TypeScript bug: https://github.com/Microsoft/TypeScript/issues/17033

I made another repro for that bug using your file, as it is simpler than the existing repro they have there.

It looks like the newly release TS 2.9.1 does not suffer from that problem. Will see if we can update Build Optimizer to use 2.9.1.

[dzonatan]

Wooow! That was fast! I want to thank you @filipesilva for fixing this so quickly! 🍻
I wish angular core team would work at such speeds.

[rogercoder]

I'm unsure as what I need to do to get away from this problem. Update @angular-devkit/build-optimizer and/or angular-cli (since that has now subsumed angular-devkit) to ... which version? Do I also need to upgrade TypeScript?

[filipesilva]

@rogercoder you should be able to update @angular-devkit/build-angular to the latest stable and that should include the fix.

I still have the same issue with @angular-devkit/[email protected] and @angular/cli @6.1.0

I am using nodejs 10.5.0.

[kamleshwebtech]

I am using Angular 7.1.0 version.

Situation is that i have added material header bar and side-bar in layout. Header bar has a hamberger button which i want to use as toggle to show and hide side-bar in layout. Rxjs is being used to remember current state of side-bar. Default state of behavioursubject is opened. I have added a condition on hamberger button function that if it is opened then set to closed or vice-versa case. But system returns me below error in console:
