(*Eğer ileri atlamak ve teknik çöküşe doğrudan dalmak istiyorsanız, 1. React Server Komponentlerinin neden tanıtıldığına atlayın.)
In the early 2010s, React revolutionized frontend development with its declarative component model and efficient virtual DOM diffing. What began as a simple view library soon became the backbone for large-scale single-page applications (SPAs). These SPAs predominantly used Client-Side Rendering (CSR), meaning the browser would download a JavaScript bundle, execute it, and construct the UI entirely on the client.
This client-centric model was flexible and highly interactive, and it defined “modern” web apps for years. However, as applications grew more complex and feature-rich, the CSR approach started to show its cracks:
-
Longer Time-to-Interactive (TTI): Hefty JavaScript bundles and client-side work meant users waited longer before they could actually interact with the page.
- Hidrasyon şişeleri: Sunucu tarafından sunulan HTML'yi etkileşimli bir uygulamaya (hidrasyon) dönüştürmek, özellikle dinamik içerik miktarının artmasıyla performans bozulma noktası haline geldi.
-
Bloated bundles: Applications often shipped far more JavaScript than necessary, burdening browsers with code for features or content that could have been delivered more efficiently.
- Ölçülemeyen Performans: Uygulama ne kadar büyük ve karmaşık olursa, tüm cihazlarda ve ağ koşullarında hızlı performansın sürdürülmesi o kadar zordur.
Next.js emerged to tackle some of these pain points by introducing Server-Side Rendering (SSR), Static Site Generation (SSG), and other optimizations. These techniques improved initial load times and offloaded some of the UI rendering work to the server. But even with SSR and SSG, the fundamental issue remained: we were still over-delivering JavaScript to the browser.
Fast forward to 2025. With Next.js 15 running on React 19, a new rendering paradigm has taken center stage: React Server Components (RSC)RSC'ler, geliştiricilerin sunucu tarafından sunulan ve müşteri tarafından sunulan bileşenleri tek bir React ağacında kesintisiz bir şekilde karıştırmalarına olanak tanır.zero JavaScript overhead. In other words, no client-side hydration is needed for those sections. Data fetching logic is also simplified by running inside server components, eliminating many unnecessary API calls from the browser. The result: leaner client-side bundles, faster interactions, and an application that’s far more performant and scalable.
This article isn’t a surface-level review of RSC. When I set out to write about using Next.js effectively in 2025, it quickly became clear that React Server Components deserved a dedicated deep dive. What follows is a technically rigorous exploration of how RSC works under the hood, how to leverage it in a Next.js 15 project, and why it represents a fundamental shift in frontend architecture.
By the end, I hope you come away with the same clarity and appreciation for RSC that I did through the process of researching and writing this piece.
Intro: From CSR to RSC — How Rendering Evolved in React
Giriş: CSR'den RSC'ye - Rendering React'te Nasıl GelişmişGeçtiğimiz on yılda, React uygulamalarını oluşturduğumuz yol temel olarak gelişmiştir ve bununla birlikte, renderleme hakkında düşündüğümüz yol.
React'te Client-Side Rendering (CSR) hakkında kısa bir tarih
React popülaritesini kazandıClient-Side Rendering (CSR) — a model where the browser downloads JavaScript, executes it, and builds the entire UI on the client. This approach gave developers full control over interactivity and state, and made it easy to build dynamic single-page applications (SPAs).
However, CSR came with notable trade-offs:
- Yavaş başlangıç yükü, özellikle mobil veya zayıf ağlarda Şöyle
- İçerik odaklı sayfalar için kötü SEO
- JavaScript ağır paketler - en az etkileşimli sayfalar için bile
- HTML yüklendiğinde bir hidrasyon aşaması gereklidir, interaktif zaman geciktirir
For a while, these limitations were just “how things were.” Then Next.js changed the game.
Next.js’in SSR ve SSG’yi React gelişimine nasıl getirdiği
When Next.jsSahneye girdiğinde, React için birinci sınıf vatandaşlar olarak sunucu tarafı rendering (SSR) ve statik site generasyonu (SSG) tanıttı.
- Şöyle
- SSR enabled pages to be generated per request, improving SEO and load speed for dynamic content.
- SSG, içeriğin dağıtım zamanında hazırlanmasına izin verdi, bloglar, dokümanlar ve pazarlama siteleri için mükemmel. Şöyle
- Incremental Static Regeneration (ISR), statik sayfaların dağıtım sonrası güncellenmesine izin vererek bu boşluğu kapatmıştır.
This flexibility helped developers strike a better balance between performance, SEO, and developer experience.
But even with SSR and SSG, there was still a lingering issue: we were still sending too much JavaScript to the browser — even for components that didn’t need to be interactive.
🧠 The rise of React Server Components (RSC) in 2025
With the release of Next.js 15 and React 19Yeni bir döneme girdik:React Server Components (RSC)Uygulamalar artık nasıl oluşturduğumuzun temel bir parçası.
Henüz hidrasyon gerektiren ve JavaScript'i istemciye gönderen SSR'nin aksine,RSC allows you to render components on the server — without sending any JavaScript to the browser at all.
It’s a big shift:
- Şöyle
- Komponentler artık doğrudan sunucu tarafındaki verilere erişebilir
- Statik içerik hidrasyon gerektirmez
- You can mix server and client components in a single React tree, composing your rendering strategy per component
RSC doesn’t replace SSR or SSG, it complements them, unlocking finer-grained control over performance, bundle size, and rendering behavior.
In 2025, RSC is a foundational concept that every senior React engineer needs to master.
1. Why React Server Components Were Introduced
1. Why React Server Components Were IntroducedAs React applications became more complex, the industry began to feel the weight of its success. While Client-Side Rendering (CSR), Server-Side Rendering (SSR), and Static Site Generation (SSG) offered different strategies for building performant web apps, each of them carried trade-offs that grew more apparent at scale.
🚧 Limitations of CSR, SSR, and SSG
1. Hydration overhead
Even with SSR or SSG, once HTML reaches the browser, React needs to “hydrate” the page — attach event listeners, reinitialize components, and effectively rebuild the app in memory. For large component trees, hydration can be a major bottleneck for Time-To-Interactive (TTI).
2. JavaScript bundle bloat
With CSR, every component, utility, and API call that’s part of the page must be sent to the browser — regardless of whether it’s interactive or not. SSR and SSG reduce this slightly, but most of the bundle still needs to be executed on the client. As apps grow, this leads to bloated bundles that slow down the user experience.
3. Disconnected data-fetching logic
In the pre-RSC world, data lived outside the components that rendered it. You had to use getServerSideProps
or getStaticProps
(or call APIs in useEffect
) to fetch data, then pass it into components via props. This separation added cognitive overhead and made code harder to co-locate and reuse.
🧠 What problems RSC was designed to solve
React Server Components (RSC), bu artan ağrı noktalarını basit ama güçlü bir fikirle ele almak için yaratıldı:let components execute on the server by default, and only send JavaScript to the browser when it’s absolutely necessary.
Eliminate unnecessary JavaScript
RSC allows components to be rendered server-side olmadanEğer bir bileşen interaktivite gerektirmezse, JS paketini nemlendirmeye veya yüklemeye hiç gerek yoktur.
✅ Server-side data access within the component tree
RSC, veri toplama ve görüntüleme arasındaki yapay sınırı ortadan kaldırır.Server bileşenleriasync/await
to directly access databases, file systems, or APIs — co-locating data and view logic naturally, with no need for API routes or prop drilling.
✅ Improve rendering efficiency and developer experience
By moving non-interactive logic to the server, developers can build lighter apps with smaller bundles and better performance. RSC also simplifies the mental model — you just write components, and let the framework handle where they run and how they ship.
RSC doesn’t aim to replace SSR or SSG, instead, it complements them. It lets you think at the component level, not just the page level, about what should run on the server and what belongs in the browser.
In short: React Server Components were designed to bring modern frontend development back to its lean, fast, and maintainable roots without compromising interactivity.
2. Rendering Strategies in Next.js 15: RSC vs SSR vs CSR
2. Rendering Strategies in Next.js 15: RSC vs SSR vs CSRNext.js 15 offers developers a granular rendering model that goes far beyond traditional page-level strategies. With React Server Components (RSC) becoming a first-class concept, it’s essential to understand how they compare to two familiar models: Server-Side Rendering (SSR) and Client-Side Rendering (CSR).
SSG (Static Site Generation) belirli durumlarda hala değerli olsa da, bircaching strategySSR’nin üstüne inşa edilmiştir.RSC vs SSR vs CSRFarklı çalıştırma yollarını temsil eder ve bunları anlamak, 2025'te performans ve mimari bilinçli kararlar almak için çok önemlidir.
💡 Before We Compare: What Do We Mean by "Interactive Component"?
In the context of React and Next.js, an interactive component is any UI element that requires client-side JavaScript to respond to user input or browser events.
This includes (but is not limited to):
- Şöyle
- Güncelleyen düğmeleri click on state
-
Forms with validation or controlled inputs
- Dropdowns ve open/closed geçiş yapan modals
-
Animations triggered by scrolling or hover
- Tabs, karoserler, filtreler ve sliderler Şöyle
-
Components that use
useState
,useEffect
, oruseReducer
Şöyle
If a component has event handlers• İçstate, or relies on the DOM or browser APIs, it must run on the client.
Interactivity = Browser-side behavior + JS event listeners + local state.
Understanding this distinction helps clarify why RSC exists: to avoid shipping JavaScript for UI pieces that don’t need to be interactive.

Think in Components, Not Just Pages
In earlier versions of Next.js, rendering strategies were applied at the page level. You had getServerSideProps
vegetStaticProps
, and whatever you chose applied to the Tüm sayfa. This made sense in a world where rendering happened all-or-nothing — either statically at build time, or dynamically on each request.
But with React Server Components (RSC)Ve oapp/
Next.js 13+'da tanıtıldı ve 15'te standartlaştırıldı.rendering is no longer a top-down, one-size-fits-all decision. It becomes a per-component concern that unlocks a new mindset.
A New Way of Thinking: Declarative and Composable Rendering (← bağlantılar değiştir)
Bu değişiklik bir API değişikliğinden daha fazlasıdır, frontend'inizi nasıl yapılandırdığınızda kavramsal bir değişikliktir.
Declarative
Orkestrasyon yerinenasılvewhereparçaları manuel olarak gösterilir, şimdi basitçedeclare what each component does and what it needs — React and Next.js take care of the rest.
You don’t manually wire up API endpoints or pass props from SSR to components. You can just write:
// Server Component
export default async function ProductInfo() {
const product = await db.getProduct(slug)
return <div>{product.name}</div>
}
Bu bileşen :
- Server üzerinde çalışıyor
- Doesn’t send JS to the client Şöyle
- Doesn’t require any
getServerSideProps
or API layer - “Sadece bir bileşen” – ekstra bir abstraksiyon gerekmez
UI ve veri ihtiyaçlarını tanımlardeclarativelyDiğer motorlar ise gerisini gösteriyor.
Composable
UI'nuzun farklı bölümleri farklı render stratejileri kullanabilir -on the same pageveat the same time, and with minimal overhead.
Örneğin :
// Product page layout
<ProductInfo /> // Server Component (no JS, rendered on the server)
<AddToCartButton /> // Client Component (interactive)
<SimilarProducts /> // Static Component (SSG with revalidation)
Bu bileşenler aynı ağaçta birlikte yaşar, ancak her biri:
- Runs in a different environment (server, client, build) Şöyle
- Uses only the data and code it needs
- Tarayıcıya tam olarak gerekli olanı gönderir - ne daha fazla, ne de daha az
Bu konuyu daha net bir şekilde anlatmak için, birDemo MinimumTek bir sayfada farklı gösterme stratejilerinin nasıl birlikte var olabileceğini gösterir.
3. How React Server Components Work Under the Hood
3. React Server bileşenleri kapağın altında nasıl çalışırReact Server Components (RSC), sadece yeni bir renderleme stratejisinden daha fazlasıdır, bileşen ağaçlarının nasıl inşa edildiğini, renderlendiğini ve iletildiğini temel olarak değiştirir.how it works behind the scenes and how it impacts the boundaries of state, interactivity, and data.
🧱 Server/Client Boundary: A Split React Tree
React applications using RSC are no longer fully rendered on the client. Instead, the component tree is split into two worlds:
- Şöyle
- Sunucu bileşenleri: Yalnızca sunucu üzerinde çalıştırın. Hiçbir zaman tarayıcıya JavaScript gönderilmez. Yerel durum tutamaz veya olay dinleyicileri ekleyemez. Statik içerik ve sunucu bağlı mantık (örneğin, DB erişimi) göstermek için mükemmel.
- Client Components: Must be explicitly marked with
"use client"
. These are compiled into browser-friendly JavaScript and support full interactivity, local state,useEffect
, and event handling. Şöyle
At build or runtime, React constructs a tree where server and client components coexist and stitches them together during render.
📍 What "use client"
Actually Does
When you add "use client"
to a file, it marks that entire module and its exports as client-only. Behind the scenes, this instructs the Next.js build pipeline to:
- Şöyle
- Compile that file (and its dependencies) into a separate JavaScript bundle Şöyle
- Exclude that component from being run on the server
- Treat it like a classic React CSR component with hydration logic
This directive acts as a boundary markerYukarıdaki tüm bileşenler sunucu tarafından render edilebilir; Aşağıdaki tüm bileşenler tarayıcıda render edilmelidir.
💧 Streaming: Rendering in Pieces, Not All at Once
RSC Öpücükstreaming as a native rendering strategy. Instead of waiting for the full React tree to be built before sending it to the browser, the server streams serialized fragments of UI to the client as they become ready.
- Şöyle
-
Server Components are rendered and sent as soon as possible
-
Placeholders (e.g. via
<Suspense>
) fill in temporarily - Müşteri bileşenleri giderek nemlendirir, sadece yüklendiğinde Şöyle
✅ How is this possible?
RSC, seçici hidrasyon olarak adlandırılan bir kavramı tanıttı.Kullanıcı bileşeni bir Sunucu bileşen ağacı içinde gösterildiğinde, React bir yer tutanı (<div data-rsc-placeholder />) yerleştirir ve hidrasyonu devre dışı bırakır.
Once the client has loaded the corresponding JS bundle:
- React lazily bu özel bileşeni yükler Şöyle
- Finds the placeholder and stitches it into the live tree
- Hydrates it in isolation, without re-rendering the entire page
This design is decoupled and progressive: your app starts fast, and interactivity comes online gradually.
<Suspense fallback={<LoadingDetails />}>
<ProductDetails /> // Server Component
</Suspense>
<AddToCartButton /> // Client Component (hydrated later)
⚙️ Data Fetching and Code Splitting in RSC
Another key “magic” of RSC: you can fetch data directly inside components with async/await
Bağımlılık yapmadangetServerSideProps
veuseEffect
Ya da manuel geçiş.
// Server Component
export default async function Dashboard() {
const stats = await getStatsForUser()
return <StatsView data={stats} />
}
Why is this possible?
- Şöyle
- RSC bileşenleri, müşteri tarafından kompile edilen modüller değil, gerçek sunucu fonksiyonları olarak çalışmaktadır. Şöyle
- They can access databases, internal APIs, file systems, or anything your server runtime supports
- Sonuç HTML (JS değil) gösterilir ve istemciye aktarılır Şöyle
Ayrıca :
- No hydration needed, since the result is static
- Kendi bileşeninde yükleme UI mantığı yok - her şey tarayıcıya çarpmadan önce çözülür
- Bu bileşen için herhangi bir kod istemciye gönderilmez - bir istemci sınırının içinde yerleştirilmedikçe Şöyle
This significantly reduces boilerplate and bundle size, while keeping logic colocated with UI — a long-standing React goal finally realized at scale.

4. What’s the Best Practice? Combining RSC, SSR, and SSG
4. En İyi Uygulamalar Nelerdir? RSC, SSR ve SSG BirleştirmeOne of the most common questions React engineers face in Next.js 15 isn’t “should I use RSC?” — it’s “how do I combine RSC with SSR and SSG in a maintainable, high-performance way?”
The beauty of Next.js 15 is that you’re no longer limited to one rendering strategy per page. Instead, you can now compose rendering strategies at the component levelUygulamanın her bir parçası için en uygun yaklaşım uygulanır.
This section introduces a practical framework for making that decision based on actual architectural needs.
🧭 Start with the Core Question: What does this component need?
Ask these four questions for every component:
- Does it need to be interactive?
- ✅ Yes → Use a Client Component
Şöyle - Does it need secure, request-specific, or real-time data?
- ✅ Yes → Consider SSR
- Önceden hesaplanabilir veya nadiren güncellenebilir mi? ✅ Evet → SSG tercih Şöyle
- Does it fetch server data but never need to run on the client?
- ✅ Yes → Use RSC

📐 Design Best Practices for Combining Strategies
✅ 1. Start Server-First
Design every component as a Server Component by default. Opt into interactivity ("use client"
) only when necessary. This keeps bundles smaller and simplifies testing.
2. Sınırları açık tutun
Sınırları açıklayıcı hale getirmek için klasör adlandırma veya dosya adının devamını kullanın:
/components
/server/ProductDetails.tsx
/client/AddToCartButton.tsx
/shared/ReviewStars.tsx
✅ 3. Gelişmiş Teslimat için Suspense Kabul
kullanmak<Suspense>
to stream in non-critical RSCs without blocking the whole page:
<Suspense fallback={<LoadingReviews />}>
<ReviewList />
</Suspense>
✅ 4. Logik ile bileşenleri yerleştirin

ISR (Incremental Static Regeneration - artan statik yenilenme)
For cacheable, high-traffic pages like blog articles or marketing sections, use SSG + revalidation:
export const revalidate = 3600 // regenerate every hour
✔️ Kaçınılması Gereken Yaygın Hatalar
- ❌ Using
"use client"
by default — you’ll end up with CSR all over again - ❌ Fetching data in client components when it could be server-fetched
- 🔸 RSC ve müşteri bileşenleri arasında çok fazla veri aktarmak - bunun yerine, müşteri bileşenlerinin odaklanmış, yalıtılmış ve devletli olması
- ❌ Recreating SSR-style
getServerSideProps
logic inside RSC — no need, RSC is server-side
✅ Decision Tree Summary
Here’s a simplified guide:
Is it interactive?
│
├── Yes → Client Component (CSR)
│
└── No
│
├── Needs per-request data? → SSR
│
├── Can be pre-rendered? → SSG
│
└── Otherwise → RSC
You don’t need to memorize it. Once you internalize how rendering maps to responsibility, the decisions become intuitive.
The best practice isn’t about picking “the best rendering strategy.”

6. Looking Ahead: Why RSC Is More Than Just a Feature
6. Looking Ahead: Why RSC Is More Than Just a FeatureReact Server bileşenleri sadece bir performans optimizasyonu veya bir DX geliştirme değildir.they represent a foundational shift in how we build React applications. Much like React Hooks in 2019, RSC in 2025 is redefining the baseline for frontend architectureve .
🧠 RSC Changes the Mental Model of Building in React
Traditional React development was always built on this assumption:
“The browser owns the runtime. We hydrate everything. Every piece of logic and data must live in the client, or be fetched via API.”
RSC breaks that assumption.
With RSC, you now ask:
- Can I skip hydration entirely?
- Can this component run purely on the server?
- UI ile backend mantığını yerleştirebilir miyim?
It gives us back the ability to separate display logic and interactivity cleanly, not with wrappers and workarounds, but with first-class architectural boundaries.
It’s no longer “client-first.” It’s “purpose-first.”
Each part of your UI exists where it’s most efficient — server, client, or static.
🌐 Ecosystem Shift Toward Server-First Rendering
RSC isn’t happening in isolation. The broader frontend ecosystem is undergoing a server-first rendering renaissanceve .
Frameworks like:
- Şöyle
- Remix büyük ölçüde sunucu veri yükleme ve form eylemlerine bağlıdır. Şöyle
- Astro embraces zero-JS by default, shipping only islands of interactivity. Şöyle
- Qwik takes hydration to the extreme — deferring all JS until explicitly needed.
- Next.js 15, RSC ve App Router ile, şimdi geliştiricilerin deneyiminin merkezinde bileşen başına rendering koyar.
This isn’t a coincidence. It’s a reflection of a hard truth we’ve all felt:
Sending less JavaScript is the only way to scale interactivity and performance on the modern web.
React Server Components are the React-native answer to that challenge — deeply integrated, ergonomic, and production-ready.
🔮 What to Expect Next
The evolution is still ongoing. As React 19 and the ecosystem mature, we can expect:
- Şöyle
- More granular debugging and profiling tools for RSC trees Şöyle
- Better DevTools integration to show boundaries and hydration timelines
- Higher-order patterns to abstract rendering strategy (e.g.,
<ServerOnly>
,<DeferredClient>
wrappers) Şöyle - Broader adoption in design systems, frameworks, and libraries (e.g., RSC-aware UI kits) Şöyle
