QUESTION
This is somewhat related to a previous question I asked. The feature$ function in that question returns an observable with a map that uses the parameter passed to the function:
...ANSWER
Answered 2022-Mar-04 at 00:39The the second stream example is a bit overly complicated, your features$$ is a Behavior subject that might continuously updating itself. Your intend is only take in parameter and process through the features array and output the found feature, the first form of the code is more appropriate.
As the source stream is a BehaviorSubject you will always have a value once subscribe(), just don't forget to unsubcribe() to prevent memory leak. Alternatively use take(1) or first() operator before subscribe()
When you create an observable from a function you get a new instance of that stream, it is a hot observable but not shared(), so filtering on 'featureA' wouldn't affect result on filtering on 'featureB', and yes of() and combineLatest() really does nothing in your use case, as those are static and unchange function param
QUESTION
mFeaute is a mutable object.
I want to know if the change of mFeature in setFeature(Feature feature) is visible to mFeature in useFeature(...) with a different explicit form of synchronized.
Thanks.
...ANSWER
Answered 2021-Oct-27 at 16:05It is unclear what you are trying to synchronize on (ClassA and ObjectB are vague). In general, you want to synchronize on a single mutex when interacting with a given shared resource. Create an Object to serve as the mutex upon which you synchronize when accessing the internal mFeature.

Answered 2021-Oct-06 at 17:22I'm not sure in all your layers where this goes, but you just need to set the Navigation Property (possibly a Shadow Property in EF Core), for the FeatureTypeId, or explicitly mark the FeatureType as Unchanged, after (or in)

I am work on the angular testing for first time and from monring i struggling to test this. I added both modules inside TestBed and injected but real method is always called instead of returning value from getMockFeatureState(). Please help fix this. Thannks

Answered 2021-Jun-07 at 13:13I recently faced the same issue in one of my tests. The order of TestBed.inject was the issue. If FeatureToggleService requires ConfigService. You have to inject ConfigService first and mock it before injecting the featureService. You can try
QUESTION
My Arrow function in subsctiption of observer not changing changing local variable bool
...ANSWER
Answered 2021-May-18 at 06:08Your subscribe function is asynchronous, this means when the this.featureService.upVoteAvailable(i) is called the code will not stop and wait for the Observable to return.
So in the end you need to wait for the Observable to return.
There are several ways to do so.
The easiest way is to use async/await.

QUESTION
What i want to achieve:
I have a FeaturesService that should provide the information if a certain feature is enabled by providing different Promises.
The list of enabled features is provided as json object via an HTTP API (see DataService).
Before the HTTP request to get the list of features is send, we need to make sure the user is authenticated first (see AuthService).
Furthermore:
- The features request should only be made as soon as someone uses one of the
Promisesprovided by theFeaturesService(e.g.isFeatureXSupported), not necessarily on start of the application or as soon as the user is authenticated. (cold observable?) - The features HTTP request should only hit the network once, and should be cached (replayed) afterwards

QUESTION
When I run my prod build of my Angular 8 app, I am getting this error in console. The build runs fine and I've included all services in my provider.
I've run the following commands but do not get any errors.
ng build --prod --optimization=false
Is there any way to tell what is failing? Even when I comment out all the providers (expecting the build the fail), I still receive no errors.
Please let me know what other information I can/should provide for your help. Thanks!
