App that compiles and runs using immutable 4.3.2, fails to start after upgrading to 4.3.3. Seems to be caused by #1932
Attempting to run app results in error: Error: Failed to initialize Angular compilation - Maximum call stack size exceeded
To duplicate:
Create an angular app - npx @angular/cli new TestApp (choose no routing and css)
Install immutable 4.3.2 - npm i immutable@4.3.2
In tsconfig.json change the value of noImplicitOverride option from true to false.
Replace the contents of app.component.ts with the following (which kind of captures the problematic code in more or less the way its actually presenting):
import { Component } from '@angular/core';
import { /*DeepCopy,*/ List, Record } from 'immutable';
export interface Props {
foos?: List<Foo>;
}
const defaults: Props = {
foos: undefined // null
};
const fooRecord = Record(defaults, 'Foo');
export class Foo extends fooRecord implements Props {
foos?: List<Foo>;
}
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'TestApp';
// either of these causes issue
// bar: DeepCopy<Foo>;
bar = List<Foo>([new Foo()]).toJS();
}
Run the app - npm start. It starts as expected.
Upgrade to immutable 4.3.3 - npm i immutable@4.3.3
Run the app - npm start. App fails to start with Error: Failed to initialize Angular compilation - Maximum call stack size exceeded
If line 15 - foos?: List<Foo>; is commented out we get a more descriptive error:
Error: src/app/app.component.ts:28:3 - error TS2615: Type of property 'foos' circularly references itself in mapped type '{ [ObjectKey in keyof Props]: DeepCopy<Props[ObjectKey]>; }'.
