In short
Modern front-end architecture is chosen by matching rendering strategy (static, server-rendered, or client-rendered) to the actual content and interactivity needs of the project, structuring components around genuine reuse boundaries, and keeping state management as simple as the real complexity requires — not defaulting to the most powerful available option.
Architecture decisions compound
The rendering strategy, component structure, and state management approach chosen at a project's start shape its ongoing cost and flexibility for years — these aren't cosmetic choices, they're structural ones that are expensive to reverse later. Getting them right requires matching the choice to the project's actual needs, not defaulting to whatever's currently popular.
Choosing a rendering strategy
- Static. Pre-rendered at build time, served as plain HTML. Fastest possible load, simplest deployment, ideal for content that doesn't change per-request — see how to ship a static site with zero build step for the lightest version of this.
- Server-rendered. HTML generated per request on the server, often with client-side hydration for interactivity. Good for content that's dynamic per-request but still benefits from fast initial paint and search-engine crawlability.
- Client-rendered. HTML generated in the browser after a JavaScript bundle loads. Suited to highly interactive, app-like experiences where the tradeoff of a slower initial load is acceptable for a richer ongoing interaction model.
Most real projects benefit from mixing these per-route rather than committing a whole site to one strategy — a marketing homepage static, a dashboard client-rendered, within the same project.
Structuring components around genuine reuse
Components should be extracted around actual, repeated reuse boundaries — not speculative future reuse that may never materialize. Over-abstracting early, before a second real use case exists, tends to produce components with awkward, overly generic APIs trying to anticipate needs that don't yet exist; extracting a component the second time a pattern genuinely repeats usually produces a cleaner abstraction than guessing upfront.
State management: match complexity to actual need
A large share of state in most applications is local to a single component or a small subtree, and doesn't need a global state management solution at all. Reach for more powerful state tools (global stores, complex state machines) only once genuine cross-cutting state complexity actually exists — not preemptively, since the added complexity of a heavier state solution has real ongoing cost even when the problem it solves isn't present yet.
Data fetching patterns
Decide deliberately whether data is fetched at build time (static), on the server per request, or client-side after initial render — this interacts directly with the rendering strategy choice above and affects both perceived performance and how fresh the displayed data can be. Mixing these appropriately per route, rather than picking one pattern globally, usually serves a real project's varied needs better.
Avoiding premature framework lock-in
Adopting a specific framework's opinionated patterns throughout a codebase makes a future migration expensive if the framework's fit degrades as the project's needs evolve — keeping genuine business logic reasonably decoupled from framework-specific APIs where practical preserves some flexibility, though this is a tradeoff against the framework's own productivity benefits, not a free option.
A practical decision framework
For any new project or major feature, explicitly answer: does this content change per-request or per-build, how much genuine client-side interactivity does it need, and how much of its state is actually shared across components versus local to one. These three questions, answered honestly rather than assumed, drive most of the architecture decisions that matter.
The cost of getting this wrong
An architecture chosen to match a project's actual needs is cheap to work within and extend; one chosen by default or by current trend, mismatched to actual needs, produces ongoing friction — unnecessary complexity for a simple project, or an under-powered structure straining against a genuinely complex one. The decision is worth deliberate attention precisely because it's expensive to reverse.

Common questions
Should I always use the most powerful available front-end framework?
No — match the rendering strategy and state management complexity to the project's actual needs; over-powered architecture for a simple project adds ongoing cost without corresponding benefit.
Can a single project mix rendering strategies?
Yes, and it's often the right call — a marketing homepage can be static while a dashboard in the same project is client-rendered, matching each route's actual needs rather than committing the whole project to one strategy.
When should I introduce a global state management library?
Once genuine cross-cutting state complexity actually exists in the project, not preemptively — most state in a typical application is local to a component and doesn't need a global solution.
