Still copy-pasting localStorage.setItem() and manual unsubscribe everywhere? Meet inject-powered magic:
injectPersistentSignal() — syncs state to storage & across tabs in one line
takeUntilDestroyedPlus() — auto-unsubscribe, zero leaks, zero worries
@auditLog decorator — logs every call, no more scattershot console.logs
Type-safe dialogs — no more “undefined is not a function” at 2 a.m.
Instant theme toggles that survive reloads and sync across devices
Visibility signals — lazy-load only when truly visible
Real wins:
- Boilerplate gone, mental load slashed
- Clearer, smaller components
- Reactive patterns that just work
Takeaway:
Injection Context in 2025 isn’t a nice-to-have — it’s the new standard for elegant, resilient, modern Angular code.
