HTTP request caching is an important tool for improving performance and reducing server load. However, implementing caching often requires writing a large amount of repetitive code, as well as carefully designed logic to control cache lifetime and data updates. In this article, we will explore a simple way to organize request caching in Angular. This can be considered a starting point — the initial steps toward optimizing requests made through HttpClient.

Error handling is a tricky task, frameworks provide basic solutions, but they rarely cover all scenarios. Errors come in various forms, and the handling logic is often duplicated and scattered throughout the code. To bring order to this process, a lot of code has to be written manually.

This article provides an overview of the key points that need to be covered when studying the topic of Inversion of Control.

Inversion of Control (IoC) is a fundamental design principle in software engineering that shifts the control of object creation and flow of execution from the application code to an external framework or container.
