Common Causes of High Memory Usage in Angular

1. Memory Leaks: Components and services not properly cleaned up can cause memory leaks.
2. Excessive DOM Manipulation: Too many DOM elements or frequent updates can increase memory consumption.
3. Large Data Objects in Memory: Keeping large objects or arrays in memory unnecessarily bloats memory usage.
4. Unoptimized Change Detection: Running change detection frequently for all components degrades performance.
5. Improper Use of Observables: Subscriptions that are not unsubscribed can lead to memory leaks.
6. Large Bundle Size: Loading too much JavaScript can impact memory consumption.

The httpResource API is still experimental, but it will most likely replace all our usages of HttpClient in the near future, which is why I’m excited to share this now!
