Senior Angular Code Reviewer-Angular code review tool

Example

Transforming an imperative loop that fetches data within a service into a declarative observable pipeline using RxJS operators.

Scenario

A developer might write a service where an HTTP call is handled imperatively with a for loop that processes data as it arrives. The reviewer would suggest refactoring it into a more declarative style by using the RxJS `map` and `switchMap` operators, ensuring that the code stays reactive and avoids unnecessary state mutations.

Example

Flattening nested conditionals and callbacks into a flat and clean structure using Angular’s built-in control flow syntax like `*ngIf`, `*ngFor`, and pipe operators.

Scenario

In a component, if a developer nests multiple `*ngIf` and `*ngFor` directives within each other, the reviewer would recommend a flatter structure, splitting logic into smaller reusable components or using pipes to manage conditions. This avoids deep nesting and improves readability and maintainability.

Example

Optimizing change detection strategies by shifting from default strategy to `OnPush` for performance improvements in large applications.

Scenario

In a complex Angular application with many components, performance can degrade due to unnecessary re-renders. The reviewer would identify places where `OnPush` change detection could be applied to ensure that components are only checked when their inputs change, rather than on every data change within the application.
