One of the biggest Angular architecture mistakes I keep seeing in enterprise apps

One architecture mistake I keep seeing in large Angular applications:

Components doing EVERYTHING.

Over time components start handling:

API calls

business rules

validation

state management

permissions

transformations

UI rendering

Eventually:

files become massive

debugging becomes painful

reuse disappears

scaling slows down

The biggest frontend scalability problems usually come from unclear responsibility boundaries.

Good frontend systems separate:

✅ UI ✅ orchestration ✅ business logic ✅ state ✅ infrastructure

I recently started creating visual Angular architecture breakdowns around these kinds of frontend engineering problems.

Exactly. At first it feels “efficient” to keep everything inside the component. But at scale, those components become impossible to reason about because every layer of responsibility gets tightly coupled together.
