I built a Signals-first toolkit for Angular. Here is the problem I could not stop hitting.

Every Angular application I have worked on in the last few years had the same three kinds of state: URL state — the page number, the active filter, the selected tab. Client state — what the user typed, what is expanded, what is selected. Server state — the thing you fetched, and everything that can go wrong while fetching it. And every application handled them three completely different ways. ActivatedRoute and a Router.navigate call for the first. Signals or a store for the second. A service returning an Observable , plus a loading boolean, plus an error field, plus a subscribe somewhere, for the third. None of that is wrong. It is just that the glue between them is written by hand, in every app, every time. And the glue is where the bugs live. This article is about the specific piece of that problem I could not let go of, and about the toolkit I ended up building around it. It is called craft-ng , it is in beta, and I would genuinely rather have your objections than your stars. The code I kept running into Here is the shape. I should be honest: I did not write much of it myself — I had a drawer of RxJS helpers that hid most of it. But I have read it in a lot of codebases, reviewed it in a lot of pull requests, and inherited it in a lot of projects. That turned out to matter more, because a helper that only I understand is not a solution to anything. @ Injectable () export class TaskListService { private http = inject ( HttpClient ); tasks = signal < Task [] > ([]); isLoading = signal ( false ); error = signal < string | null > ( null ); load ( done : boolean ) { this . isLoading . set ( true ); this . error . set ( null ); this . http . get < Task [] > ( `/api/tasks?done= ${ done } ` ). subscribe ({ next : ( tasks ) => { this . tasks . set ( tasks ); this . isLoading . set ( false ); }, error : ( err ) => { this . error . set ( ' Something went wrong ' ); this . isLoading . set ( false ); }, }); } } Four fields, one method, and roughly six ways to get it subtly wr
