What is (Frontend) Architecture?

September 26, 2024 • 📚 21 min read
While working on applications (let it be React, Angular, Vue, pick your favorite one), we make architectural decisions all the time. It's extremely important to be aware of them, i.e. have architectural drivers in mind, be aware of the tradeoffs of these decisions and cope with the limitations. Or maybe you think that it's all overcomplicated and Frontend Architecture is just the directory structure?

The "hot and cold" observables concept is quite useful when we introduce RxJS to a complete beginner.

Recent release of Angular 17.1 (18th January 2024), introduces Signal Inputs. It's a good opportunity to rethink migrating from RxJS to Signals, as more and more APIs are signal-based: the framework (signals, computeds, effects and the rxjs-interop) and ecosystem (NGRX signal store), as well as tons of experiments.

Type Inference is the most important feature we should master, as we progress with using TypeScript. It allows us to keep the type safety of our codebase, and declare types less. Less investment cost, same profit.
