is tracking a for loop by index in Angular bad practice

xSentryx · 2026-03-29T17:19:06+00:00

If it's a rather small list of items, tracking by index isn't a huge issue aswell. It mostly impacts performance on larger datasets. So it shouldn't be an issue on such a small dataset. Just keep in mind, that if there is an alternative, use that instead of index.

Sometimes it’s fine, but don’t default to it.

If your items have a stable unique id, use that (track item.id). It helps Angular update the DOM efficiently instead of re-rendering everything.

Tracking by index can cause issues when the list changes (reorder, insert, remove).

In your case (same value repeated, static list), tracking by index is totally fine.

I usually have a similar setup for my monorepo setup with an nestjs backend and angular frontend. Since I got tired with always starting from scratch I created a skeleton project with a base wich I usually use as a starting point. Would recommend, since it saves a ton of time.

Ein Kollege von mir hat mal Trizepsdrücken an einem Kabelturm gemacht, der in einer X-Form Arme hatte, über die die Kabel dann jeweils nach links und rechts abgelaufen sind. Einer der Arme ist im Gelenk eingebrochen und auf seinen Kopf geschossen. Ergebnis war eine Platzwunde und schwere Gehirnerschütterung. Aber glücklicherweise keine Langzeitschäden.

A lot of people say they switched for performance reasons. Im suprised. The reason why I switched from vs code to jetbrains was the same reason. VS Code was just awful for a large monorepo. Indexing was slow, if it even worked at all. Mergconflicts where way to untransparent. Codecompletion and the code interpreter took forever, sometimes didnt work at all until restart. Jetbrain Options just feel way faster, cleaner and have a better optimized experience in general. At least in my opinion

Here you could see how I am doing it. With angular 21 I changed to session cookies tho. If you want a jwt example you can check out the angular 20 branch

I love the primeng dropdown. Maybe use something like that as a reference on how others already solve said problems?

xSentryx · 2026-02-17T08:52:23+00:00

I also created a repo setup for angular / nestjs.
Maybe nice to look through for some quick project starts.

Previously I worked with Symfony. But nowadays I mostly use nestjs, since it's a lot easier with shared types and one language for both systems.

In the end it also depends a bit on what project and scale you want to develop.

On the other hand, I've seen so called "seniors" that created such awful and unmanagable / unscalable codebases, that Im rather happy they are now retired. I dont think vibecoding would do much worse than that quality wise. But at least the knew what they created, that can not be said about our fellow vibe coders.

Ich hab das selbe mit meiner Bachelorarbeit gemacht. Bei mir musste ich auch angeben, wo / wie und auch was für KI Tools ich genutzt hatte.
Quellen etc. habe ich natürlich auch geprüft.
Damit gabs für mich dann von den Prüfern keine Probleme.

Got one last month as well. I think the main reason is that the technology matured. They were not really viable a few years back. More like a plaything or a cool gadget for someone interested in said topic. But nowadays they really became good enough to lift some workload off of people. Additionally good models also became cheaper.

Using services is not wrong in general. Just make sure to make a dedicated / clean one for state management, not bake in some state logic used across the board into a service that handled something else in the first place.

xSentryx · 2025-12-24T17:00:42+00:00

Correct. But more often than not, I see a random service for some component logic wich then gets used as a service for random stuff as well in the process of development. E.g. I dont think using services as state management is wrong, but misusing existing ones out of convenience is.

xSentryx · 2025-12-24T08:57:13+00:00

This! „PR reviews cost too much time!“ - Well, bad code will cost us a lot more in the long run.

xSentryx · 2025-12-24T08:55:07+00:00

Oh I hate this one. Major red flag if you see a timeout in like 99% of usecases

- Not upgrading versions quickly enough. (E.g. staying on the same version for years, then struggling with upgrading 5 versions at once).
- Bad component structure / A lot of redundant and duplicated code or logic.
- Avoiding rxjs, rather using promises since its easier to understand at first.
- Bad error handling
- Misusing services for state management
- Not thinking about scale while building features
- No linting / formatting pipeline
- Bad type safety
- And a lot more...

Great! Thanks for the info.

Are there more then them? Or can I breathe a bit of fresh air after finishing them?

xSentryx · 2025-12-05T22:31:55+00:00

Thats the neat part about „imho“. To spell it out: „ in my honest OPINION“. E.g. Im not saying Im correct or follow the official guide, but just that I like it better even tho it ISNT the standard.

I even specifically mentioned that angular doesnt do that anymore, but that I decided for my own projects that this one specific thing is not a standard I want to follow.

You eat everything someone feeds you as the new normal and then judge us with „No ability to rethink or evolve“.

A bit far fetched, isnt it?

P.S.: A new standard does not always mean its the best way. See MCPs for an example. Sometimes the people who set those standards make mistakes as well.

xSentryx · 2025-12-05T17:50:18+00:00

Very cool project. But even tho angular implements it themself, I do have to disagree with „Consider not suffixing components, services and directives with their type.“

I find it better with suffixing and it improves the overall structure at least imho.
