I have an Angular application that is hosted in a .net core 3.1 application. I upgraded from 8 to 9 following the official guide and now my application won't build. I get the following errors:

"Module not found: Error: Can't resolve '@angular/cdk/layout/breakpoints'", "Field 'browser' doesn't contain a valid alias configuration resolve as module looking for modules in No description file found Field 'browser' doesn't contain a valid alias configuration No description file found no extension Field 'browser' doesn't contain a valid alias configuration /@angular/cdk/layout/breakpoints doesn't exist .ts"

I get the same errors above for @angular/material/core/common-behaviors, @angular/material/core/datetime, and @angular/material/core/ripple.

I've included all the files that I thought may be helpful. I've been trying to fix this for ages and have run out of ideas. This is very frustrating, Please help.

I've noticed when using Hammer-time.js for zoom events that there is a noticeable lag in the pinch zoom event if you go from pinch in to pinch out (or vice versa) without taking your fingers off the screen.

I have only tested this on Android as I only have an Android phone and tablet available.

Often the zoom will continue to go in before turning around and going out again even though the user has reversed the action. Its obvious when zooming into something like a photograph using this method.

The jQuery code I am using is as simple as I can make it for the demonstration:

I am getting this error and I already check all the import and Modules.

I am trying to access to a JSON file inside my project and use that data in an object but I not sure what is the problem here. I have my object well define with my JSON and I am not sure that the problem is with the Http

I have an Angular 8 application that is hosted in a .net Core 2.2 MVC application. It is using a project template that bundles with Webpack 4. When I try to run it in Visual Studio 2019, it fails to load with the following error:

My code is in Angular7, using @ngrx/store7, and sometimes I get undefined state (just for a specific state)

It is always the "history" state.

I have a large project which was till now running on webpack and all was working well with angular@4.3.3. Today I planned to shift the same to ng-cli to exploit features like universal. Everything is working well and good except when i try to build the project in prod/prod+aot i am getting: Maximum call stack size exceeded.

Checked various place for the issue and most of people are telling to check for circular dependency. But as per the latest cli@1.2.7 the circular dependency should have been shown build time, which is not the case. I was planning to increase node virtual machine stack size but couldn't figure out to achieve that. I don't want to use ng eject and get into the webpack mess again.

Are there some other approaches or solutions out there with cli@1.2.7

Thanks

I've built a few apps with Angular and Firebase and I'm just starting a new one. I'm interested in how others deal with getting data using observables. In my specific app I need to use an observable to get the parameters from the URL, check if the user is authenticated, and get 2 different objects from firebase. I need to first check auth, then get parameters from the URL so I can find the locations of the firebase objects. In the past I've just done a nest of observable subscriptions like this.
