ng2-dnd | Angular 2 Drag-and-Drop without dependencies | Widget library

I received a hot potato of an Angular 4.4 application which is quite fragile. When I try to update the auth0-js module the app stops loading and its bootstrap component constructor is never called. It loads the initial html, runs app.module.ts and main.ts. Then it appears to just stop. I've gone through debugging, single-stepping, several times in Chrome & FF developer tools. It just seems to stop. I've put all sorts of console.log statements at loading and constructors of various components and modules. It apparently never calls the constructor of app.component.ts.

I have carefully isolated the changes to required modules from the auth0-js module. There is only one required module, qs, which is also used by my code or any other js modules. The other required modules are only used by auth0-js. I froze the top level qs version and forced npm to install that as a dependency of auth0-js when upgrading. I can find no changes that could cause this breakage.

And, as far as the auth0-js library itself, I have already made use of the latest version in another similar project. And, the code executed before the app just stops does not include any calls to auth0-js. In other words, that code is not touched before the app stops running.

Building is done with the Angular CLI version 1.7.4, installed local to the project (in ./node_modules/). Then it is built/launched via ng serve --env local. That server seems a black box with no useful logging. I switched to serving via nginx and building via ng build --output-hashing=all --env local. Still not getting any further. Its been several weeks and my forehead is becoming concave. Any and all suggestions are more than welcome.

Here is my main.ts

Hi i'm trying to run this code on Angular 6 after updating from angular2-modal to ngx-modialog

I have been trying to deploy my Angular 5 application, into Heroku. I already did this for other projects, but for this one, there might have some dependency problem and I can not do the same.

On my local machine, I can run ng build without any errors.

On the other hand, when Heroku is running this command (ng build), I receive the following error:

I am receiving the following error when I compile my app. I'm not sure exactly what it means. I'm fairly new to angular, and I'm trying to update some legacy code to a new version of angular. Any direction would be very greatly appreciated.

Im getting like 50 errors that all say that angular/core/core has no exported member 'eeFactoryDef'.

They come from different node_modules, for example angular/cdk, ng-bootstrap, ngx-pipes, ng2-dragula and some more. I didn't find anything from google either.

I started upgrading from Angular 4.4.4 to 5.1.1 today. I have had to upgrade a number of other packages that rely on angular as well. I get an error with so little context that I have no idea where to start. Has anyone else seen this and know what the issue is?

I just upgraded from Angular1.6 -> 4 and I am kinda stuck with the Content-Security-Protocol error :

While Upgrading from Angular 5 to Angular 7, I got few errors like map and forkJoin are deprecated. But those errors are resolved. Still left with one error while running ng serve.

Angular 4 routes not working after page refresh. It's worked before. Currently when page refresh route is going to login page(default Route) it should stay on same route.

localhost:4200/dashboard if we refresh this page it's going to localhost:4200/login

I don't know whats changes is made in project suddenly it's stopped working. Please help.
