Injectable | Dependency Injection for Swift | Dependency Injection library

How do we filter the dublicate data? I am getting response as follows:

I am using PouchDB and CouchDB in an ionic application. While I can successfully sync local and remote databases on Chrome and Android, I get unauthorized error on Safari / iOS when I run the sync command. Below is a simplified version of my database service provider.

I have a dropdown text box that does type-ahead search. When I search for a valid item name (that exists in the DB), the search works fine and returns a list of items in the drop down to select from as I type. But when I search for invalid text, the API returns a 400 error (this is good), then the HttpErrorInterceptor intercepts that response in the catchError() method, and throws up an error popup. I don't want the error popup, I want it to forward the error to the text box logic so I can just display 'No Items Found' in the dropdown.

Text box html (uses Angular's NgbTypeahead):

I am trying to setup a very small GraphQL API using NestJS 8. I installed all required redepndencies from the documentation, but when I start the server, I get this error:

I set up a Nest.Js / TypeORM / MongoDB stack as described here.

It works to create an object user in MongoDB using the create() function, the object is recorded into the right database into the User collection.

However, when I attempt to get it using the find({id}) or the findAll() function I get an error and I cannot get the item from the database even though it's there.

Here is my user.service.ts file:

I'm learning Firestore and have built an angular app. I'm using Firebase authentication and having trouble figuring out the rules to use to allow a user access to their data. So for example a products collection which each product has a userId which is actually their email address.

Example:

The current rule I have is as follows and is not working (i've tried everything I can figure based on docs, stackoverflow, etc.):

Imagine a service ABService with a method isAResponsible: () => boolean and two modules: AModule and BModule.

The question is: Is it possible to switch between AModule and BModule depending on what isAResponsible returns? And how do we 'reroute' and rerender if the value of isAResponsible changes? ABService may have several dependencies to other services so it would be preferable to make use of the DI system somehow.

Example: If the route of interest is /aorb and ABService.isAResponsible returns true, than we would like to route AModule. If ABService.isAResponsible returns false however we want BModule to manage further routing. Note that everything should happen on a shared route.

I tried it with guards and canActivate/canLoad but didn't succeed:

Yo, i have store application with nestjs, i need validate mongo id, which is pass by query, the problem is that i also pass and search query. I write pipe which validate all values, and exclude this search query

Note: I think I was able to to reproduce this (see stackblitz example). The error there is printed in the console as "INTERNAL ASSERTION FAILED: Expected a class definition". This is different to what I get locally but to me this looks like the same issue.

Anyway, just comment out line 15 in app.component.ts and the error will disappear.

I am trying to get started with Firebase but when I install & compile the Angular project I am getting the following error:

Module not found: Error: Package path ./compat is not exported from package /home/sfalk/workspaces/web-mobile/node_modules/firebase (see exports field in /home/sfalk/workspaces/web-mobile/node_modules/firebase/package.json)

The interesting thing is that I am only getting this error when I am injecting my AuthService e.g. like this:
