Master the six essential React design patterns that solve real problems in modern applications. From Composition and Custom Hooks to Providers, Compound Components, Server/Client Separation, and Suspense—each pattern includes real-world analogies, practical code examples, and visual diagrams.
A practical walkthrough of the 5 SOLID principles and 23 GoF design patterns, with side-by-side examples in JavaScript, Python, and Rust. The goal is simple: see the same idea expressed in three different type systems and paradigms, and let the differences teach you something.
After having your project fully tested, deployed and running, it seems the application architecture is pretty good enough. All the requirements met and everybody is happy. But then as it happens, the requirements change and you, all of sudden, find yourself in the time of troubles. It comes out that some modules easier to hack than to modify. Change of other ones brings endless changes in a cascade of dependent modules. Or you change one module and whole the application starts to collapse like a house of cards. And, of course, you find out that you can’t reuse already written modules for the new tasks, because the encapsulation of the desired parts would take too much risk and work. Robert C. Martin was very accurate naming those symptoms of rotting design as Viscosity, Rigidity, Fragility and Immobility
