Describe the proposal

we have used fmt.errorf to formatted error in the entire code bases, but this loses many information.

The other projects, such as Kubernetes, switched to https://github.com/pkg/errors to wrap errors in contextual information and still preserve the underlying error and originating stack trace.

instead of using fmt.errorf,

Minimal reproduction of the bug/regression with instructions:

1. Generate a new project
2. Run ng add @ngrx/component
3. Notice the error

Hi @felangel ,

I was looking for some examples of Hydrated BloC, I just found this (https://github.com/felangel/hydrated_weather), and even then it seems like it didn't update, would you like to provide some more examples like login App for example.

Thanks for your awasome libraries, these really provide benefits to us.

stackblitz example: https://stackblitz.com/edit/angular-ivy-jvewmr?
browse https://angular-ivy-jvewmr.stackblitz.io/worker-archive/worker-dashboard

common.state.ts

import { Action, Selector, State, StateContext } from '@ngxs/store';
import { NzMessageService } f

what is prefer way to add relation and remove relation? I found example as below, but I did't find any document about the two methods.

 case 'ADD_AUTHOR_TO_BOOK':
        Book.withId(action.payload.bookId).authors.add(action.payload.author);  // add new entity ,  add relation?  this doesn't work.
        break;
    case 'REMOVE_AUTHOR_FROM_BOOK':
        Book.withId(action.payload.bo

We're looking for a contributor that wants to create our own devtools.

I have a very big app and do not want to make a placeholder for each screen I would like to provide context to about what is loading. (And also do not want a general 'loading' message). Is there currently a way to change the title/subtitle easily for each ViewController, from the ViewController itself?

This needs to be done for:

• mobx
• flutter_mobx
• mobx_codegen

I would love to have native examples of all the state systems in https://snack.expo.io/

This is a bit of a haul, help needed.
