For a new React web app in 2026, start by deciding whether you want an integrated framework or a deliberately client-only setup. React recommends starting with a framework for most new apps; its listed web options include Next.js App Router and React Router. A single-page app can still be deployed to a CDN or static host, so choosing a framework does not mean every route must use server rendering.
Choose the architecture before you create the project
Base the choice on what you are building and what your team wants to maintain—not on a claim that one tool is universally fastest or best. Consider the app’s target (web or native), routing and data-loading needs, rendering model, hosting environment, and the amount of infrastructure work your team is prepared to own.
- Web or native: For Android or iOS with native UI, Expo is React’s listed route. It is not simply another web-only framework.
- Integrated or custom: A framework brings more of the application structure together. A build tool gives you more control, but leaves more architectural choices to your team.
- Rendering needs: Decide whether the app benefits from client-side rendering (CSR) alone, or whether some routes need server-side rendering (SSR), static-site generation (SSG), or React Server Components (RSC).
- Deployment: Check that the hosting platform and runtime you intend to use support the framework’s deployment model.
React says its recommended frameworks support CSR and single-page apps (SPAs), and can be deployed to a CDN or static host without a server. They also allow server rendering on individual routes where it is useful. A framework therefore does not require you to server-render the whole app.
Compare the main React paths
| Path | Consider it when | Trade-offs to check |
|---|---|---|
| Next.js App Router | You want an integrated React web application with routing and server/client rendering features. | Understand the Server and Client Component boundary, verify deployment requirements, and decide whether the server features suit the app. Next.js documents Node.js and Docker hosting, self-hosting, and static export in its documentation. |
| React Router framework | You want routing integrated with a Vite-based full-stack framework that uses standard Web APIs. | Compare its deployment templates and runtime or platform needs with your target environment. |
| Vite, Parcel, or Rsbuild with React | You are intentionally building a client-side SPA, have unusual constraints, or want to select and configure the application’s pieces yourself. | You take on more decisions about routing, data fetching, SSR, SSG, and RSC. React cautions that this custom setup can be harder to extend and maintain as needs change. |
| Expo | Your project targets Android or iOS with native UI, potentially alongside web. | Treat it as the native-app path and evaluate it against the needs of your mobile product. |
React’s current starting point and its discussion of a custom setup are in Creating a React App and Build a React app from Scratch. Those documents describe capabilities and trade-offs, not a universal benchmark winner.

When a framework is the practical starting point
A framework is a reasonable default when the application needs routes and you want routing, data loading, rendering options, and deployment conventions to fit together. The React team’s February 14, 2025 post about Create React App (CRA) put it this way: “A good rule of thumb is if your app needs routing, you would probably benefit from a framework.” This is guidance from that post, not a rule that every project must follow.
React lists Next.js App Router and React Router for web projects. Choose between them by checking the application’s needs and the deployment environment rather than assuming one is the only supported way to build a React app.
When a client-side app or custom build is a better fit
A browser-focused SPA can make sense when it does not need server rendering and the team has a clear plan for routing, data fetching, and hosting. React documents Vite, Parcel, and Rsbuild as build-tool choices for starting from scratch. That flexibility comes with responsibility: your team must assemble and maintain more of the application architecture.
Be especially deliberate before adding SSR, SSG, or RSC to a plain build-tool setup. React’s from-scratch guide notes that these approaches require extra setup; it describes RSC setup as requiring deep expertise. It also warns that poorly coordinated code and data loading can create a waterfall. Route-level code splitting integrated with bundling and data fetching can reduce the initial load and time to the largest visible content, but splitting alone does not guarantee a faster experience.
Understand Next.js Server and Client Components
In the Next.js App Router, Server Components render on the server; Client Components provide browser interactivity. The distinction affects where code runs and how the application is delivered—it is an architectural boundary, not just a label in a component file.
On the first load, Next.js uses HTML to show a non-interactive preview, an RSC Payload to reconcile component trees, and JavaScript to hydrate Client Components. On later navigations, the RSC Payload is prefetched and cached while Client Components render on the client. The Next.js page covering this behavior was last updated March 16, 2026: Server and Client Components.
The use client directive marks a boundary between server and client module graphs. Keep it focused on interactive components rather than applying it to large portions of the interface; Next.js recommends this approach to help keep browser bundles smaller.

TypeScript is optional, not a prerequisite imposed by React. It can provide correctness checks and inline editor documentation for component props. If a TypeScript file contains JSX, use the .tsx extension. React’s built-in Hook type definitions are included in @types/react. See React’s Using TypeScript guide.
Best Value
Consider React Compiler as an optimization tool
React describes React Compiler as a build-time optimization tool that automatically memoizes React components and values. That describes its documented behavior; it does not establish a specific performance gain or mean every project should enable it. Review the React reference and the integration supported by your chosen setup before adopting it.
Do not start a new app with Create React App
React deprecated Create React App for new applications in its February 14, 2025 announcement, while saying existing projects would remain in maintenance mode. Deprecation is not removal, but CRA is not React’s recommended starting point for a new app. The team directed new projects toward a framework or a build tool such as Vite, Parcel, or Rsbuild. Read the Create React App announcement.
Quick Recap
A practical decision sequence
- Confirm the target. For a web app, compare the framework and build-tool paths. For Android or iOS with native UI, evaluate Expo.
- List the routes and data needs. If you want routing and data loading integrated, begin by evaluating a framework. If the app is intentionally a client-side SPA, decide how you will supply those pieces.
- Choose rendering per need. Use CSR where it fits; consider server rendering or static generation for routes that benefit from them. Do not add SSR, SSG, or RSC simply because they are available.
- Check the deployment target. Confirm the host supports your chosen runtime and deployment approach. For Next.js, the documented routes include Node.js, Docker, self-hosting, and static export.
- Set the maintenance boundary. Choose a build tool only if the team is ready to make and maintain the additional architecture decisions. Otherwise, prefer the integrated framework that matches the product.
