Create React App Alternative: Faster Modern Tools for 2024

Create React App is officially dead, and if you’re still using it, you’re shipping an unmaintained tool with 8 known vulnerabilities. The React team deprecated CRA in February 2025 after three years without updates, and it breaks completely with React 19. Modern alternatives like Vite deliver 10–20 times faster hot module replacement, while frameworks like Next.js and Remix add server-side rendering that CRA never had. This guide covers the fastest modern tools that actually get maintained, with honest tradeoffs for each one.

Modern React Build Tools That Replace Create React App

Create React App was officially deprecated on February 14, 2025, ending its run as the go-to starter for React projects. The tool hasn’t received updates since April 2022, and running npx create-react-app today produces 8 vulnerabilities (2 moderate and 6 high). Its core dependency, react-scripts, stopped updating in the same commit back in 2022. CRA is broken with React 19 and won’t be fixed.

The modern alternatives fall into two categories: build tools and frameworks. Vite leads the build tool category with near-instant cold starts and hot module replacement that’s 10–20 times faster than webpack. Parcel offers zero-configuration setup with a Rust-based compiler. For frameworks, Next.js provides server-side rendering and static site generation with built-in optimizations. Remix focuses on user experience with nested routing and progressive enhancement.

Your choice depends on what you’re building. Pick Vite for single page applications that need speed and simplicity. Choose Next.js or Remix when you need server-side rendering or static site generation for SEO. Parcel works for quick prototypes where minimal setup matters more than advanced features.

Why Developers Are Moving Away From Create React App

CRA’s webpack-based build system feels slow compared to modern alternatives. Cold starts take several seconds, and hot module replacement can drag for minutes on larger projects. One developer reported 6-minute HMR waits with CRA that dropped to under 1 second after switching to Vite. The development server technology is outdated, and webpack configuration is locked behind react-scripts with no escape hatch for customization.

The security situation got worse over time. Running npx create-react-app right now triggers 8 vulnerability warnings, and those won’t get patched. CRA broke completely when React 19 released because nobody’s maintaining it. The react-scripts dependency that powers everything stopped updating the same day as CRA in April 2022.

No active maintainers means no fixes, no features, and no future. The repository is still on GitHub and npm without any archived status or deprecation warnings, which means new developers keep stumbling into it. AI coding assistants like ChatGPT and Claude still recommend it in their responses because their training data predates the deprecation.

The React team shifted their recommendation toward frameworks over bare build tools. Their docs mention Vite, but it’s buried in a collapsed “Deep Dive” section. They push Next.js and Remix as preferred paths, which signals where the ecosystem is headed for new projects.

Vite: The Fastest Alternative For React Projects

Vite uses esbuild and native ES modules for instant cold starts and hot module replacement that’s 10–20 times faster than JavaScript-based bundlers. Real-world migrations show dramatic improvements. One massive application went from 6-minute HMR waits down to less than 1 second, with initial build times dropping to around 20 seconds. Vite’s name comes from the French word for “fast,” pronounced somewhere between “vit” and “veet.”

Getting started takes one command: npm create vite@latest. You’ll pick a project name, then choose your template. Select “React” from the framework list, then pick either “JavaScript + SWC” or “TypeScript + SWC” for the fastest build process. SWC is a Rust-based compiler that handles transpilation faster than Babel. The scaffolded project includes a vite.config.js with sensible defaults. You can start coding immediately without configuration.

Vite’s key features include:

• Native ES modules for instant server start and lightning-fast HMR
• Near-instant hot module replacement that preserves component state
• Multi-framework support for React, Svelte, Solid, Vue, Lit, Quik, and Angular
• Built-in TypeScript integration with SWC compiler for maximum speed
• Zero configuration defaults that work out of the box
• Development server optimized for modern browser capabilities

The main limitation hits in production builds. Vite has known memory consumption issues that have affected CI/CD systems for over 3 years. GitHub issues tracking the problem have 443 upvotes despite Vite’s 11 million weekly downloads. Large applications can see production builds consume over 4GB of RAM compared to webpack’s roughly 2GB. Vite uses Rollup for production builds, which makes production build speeds similar to webpack. The development speed advantage is where Vite really shines.

Next.js For Server-Side Rendering React Apps

Next.js sits at the framework end of the spectrum, not just a build tool. Vercel maintains it as their flagship React framework with commercial backing and enterprise support.

Next.js provides hybrid rendering that mixes server-side rendering, static site generation, and client-side rendering in one application. Automatic code-splitting means each page only loads the JavaScript it needs. The framework handles route-based splitting automatically. You don’t configure it. Build a page component, and Next.js splits the bundle at that boundary.

The built-in optimizations cover images, fonts, and scripts without plugins or configuration. The Image component handles responsive images, lazy loading, and modern formats like WebP automatically. Font optimization inlines font CSS and eliminates layout shift. Script components let you control third-party script loading strategy with a simple strategy prop.

File-based routing replaces React Router. Create a file in the pages or app directory, and you’ve created a route. API routes live in the same structure as pages, making it simple to add backend endpoints to your React app without a separate server setup.

Developer experience features include:

• Built-in TypeScript support with zero configuration
• Fast Refresh for instant feedback during development
• File-based routing system that eliminates routing libraries
• Integrated API handling for backend endpoints

Next.js works best for large-scale web applications, SEO-critical websites, and content-heavy platforms. Faire migrated their entire SPA to Next.js successfully. The tradeoffs are larger bundle sizes compared to Vite and more complex initial setup. You’re locked into Next.js conventions, which is good for consistency but limiting if you need custom build configurations. Deployment requires Node.js hosting or a compatible service. You can’t host Next.js as a standard static site unless you use static export mode, which disables server-side features.

Remix Framework For Enhanced User Experience

Remix comes from the React Router team, which makes sense when you see how routing works. The framework is built on their years of routing expertise, but with a focus on user experience and web fundamentals over fancy build tools.

Remix uses server-side rendering by default with built-in nested routes that match URL segments to component hierarchies. Loaders run on the server to fetch data before rendering, which means your component gets its data as props. No loading spinners on initial render. The form handling API uses standard HTML forms enhanced with JavaScript, which means forms work even before JavaScript loads. Route actions handle mutations, giving you a structured pattern for POST requests and data updates.

Developer features built into Remix:

• Built-in TypeScript support without configuration
• Server-side rendering by default for every route
• Fast Refresh for development feedback
• Nested route loaders that parallelize data fetching

Remix optimizes for progressive web apps and content-driven applications where accessibility and user experience matter more than cutting-edge build performance. The framework works without JavaScript for core functionality, then enhances when JavaScript loads. This progressive enhancement approach means your app works for users on slow connections or with JavaScript disabled.

The learning curve is steeper than Next.js for developers new to server-side rendering concepts. The ecosystem is less mature. Fewer third-party integrations, smaller community, fewer Stack Overflow answers. Shopify acquired Remix, which stabilized funding, but the community is still catching up to Next.js in size and tooling support.

Parcel Bundler For Zero-Config React Setup

Parcel takes the “convention over configuration” approach to the extreme. Install it, point it at an HTML file, and it figures out the rest.

Parcel offers zero-configuration setup with multi-core architecture that parallelizes work across your CPU cores. The Rust-based JavaScript compiler is 10–20 times faster than JavaScript-based alternatives. You don’t write a config file unless you need custom behavior. Parcel detects languages, frameworks, and dependencies from your imports and package.json. Drop in a .scss file, and Parcel compiles Sass without a plugin. Import an image, and Parcel optimizes and bundles it.

Built-in developer features:

• Zero-config TypeScript support that works on import
• Automatic hot module replacement without setup
• Parallel multi-core processing for faster builds

Parcel works best for simple React apps, quick prototypes, and personal projects where setup time matters more than advanced customization. The simplicity that makes Parcel great for small projects becomes a limitation for large ones. Parcel is less flexible for advanced customization compared to Vite or webpack. For large projects, Parcel runs slower than Vite despite the Rust compiler. The plugin ecosystem is smaller, so less-common requirements might not have solutions.

Additional Build Tool Options For React Development

Rsbuild is powered by Rspack, a Rust-based bundler that’s 3 times faster than Vite with a webpack-compatible API. If you’ve got existing webpack configuration you don’t want to rewrite, Rsbuild gives you modern performance without throwing away your build scripts. The webpack compatibility means plugins and loaders mostly work without changes, which smooths migration from CRA or webpack-based setups.

Nx offers regularly updated React scaffolding with your choice of bundler: Vite, Webpack, or Rspack. This flexibility matters for teams with existing build infrastructure or specific performance requirements. Nx adds monorepo support, workspace management, and sophisticated caching for multi-package repositories. The tool generates React projects with your selected bundler, then layers on project graph analysis and task orchestration. For organizations managing multiple React applications or shared component libraries, Nx provides structure without locking you into one bundler.

Vite uses Rollup for production builds, which brings production build speeds closer to webpack despite the development speed advantage. The memory consumption difference matters in CI/CD pipelines where 4GB+ RAM usage can cause out-of-memory errors or require expensive CI runners. Webpack’s roughly 2GB production build memory footprint is more predictable and easier to accommodate in constrained environments.

Comprehensive Performance Benchmarks For React Build Tools

Development server performance shows the biggest gaps between tools. Vite’s cold start happens in under a second for most projects. The dev server starts before you can switch windows. Hot module replacement completes in milliseconds, preserving component state without full page reloads. The 6 minutes to less than 1 second HMR improvement from one real migration shows how dramatic the difference feels. Initial build times dropped to around 20 seconds for a massive application, compared to several minutes with CRA. The 10–20x speed advantage over JavaScript-based tools is consistent across different project sizes.

Production build performance tells a different story. Rsbuild with Rspack is 3 times faster than Vite for production builds, which matters for CI/CD pipelines running dozens of builds per day. Memory consumption becomes the limiting factor. Vite’s 4GB+ RAM usage compared to webpack’s roughly 2GB affects build server costs and reliability. Large applications hit out-of-memory errors with Vite on standard CI runners, requiring memory limit increases or more expensive infrastructure. Parcel’s Rust-based compiler delivers 10–20x faster performance on small projects but slows down relative to Vite as project size grows.

Performance-based tool selection depends on what you’re optimizing. Pick Vite when development speed matters most and you’ve got enough memory in CI. Choose Rsbuild when production build speed and memory efficiency matter more than cutting-edge dev features. Use Next.js when you need SSR and can accept slower builds for the framework features. Stick with Parcel for small projects where setup time beats raw performance.

Setting Up And Migrating Your React Project To Modern Tools

Most of your component code stays exactly the same during migration. The changes happen at the configuration and root level: build scripts, environment variables, and project structure. Your React components, hooks, and business logic don’t care whether Vite or webpack built them.

Vite Project Initialization And Configuration

Create a new Vite project with npm create vite@latest. You’ll get prompts for project name, framework (pick React), and variant. Choose “JavaScript + SWC” or “TypeScript + SWC” for the fastest build process. SWC handles transpilation faster than Babel without changing how your code works.

The main migration steps involve moving index.html from the public folder to your project root. Vite serves from the root HTML file instead of generating it. Update your package.json scripts to replace react-scripts start with vite, react-scripts build with vite build, and react-scripts preview with vite preview. Environment variables change from REACT_APP_ prefix to VITE_ prefix, and access changes from process.env.REACT_APP_API_KEY to import.meta.env.VITE_API_KEY.

The vite.config.js replaces CRA’s hidden webpack config. Basic configuration handles path aliases, proxy setup for API calls, and plugin installation. Most projects need minimal config. Vite’s defaults work for standard React apps.

Next.js Project Setup And Routing Migration

Initialize with npx create-next-app@latest. The CLI asks about TypeScript, ESLint, Tailwind CSS, src/ directory usage, App Router preference, and import alias customization. Pick your preferences. The scaffolded project includes everything configured.

Routing migration takes the most work. Convert from React Router’s component-based routing to Next.js file-based routing. A route like <Route path="/products/:id" element={<ProductDetail />} /> becomes a file at pages/products/[id].js or app/products/[id]/page.js depending on whether you use Pages Router or App Router. Dynamic segments use brackets: [id] for required parameters, [...slug] for catch-all routes.

Data fetching moves from useEffect and state to getServerSideProps, getStaticProps, or React Server Components in App Router. API routes go in pages/api or app/api instead of a separate Express server. The refactor touches every route component, but the actual component logic stays mostly the same.

Remix Project Creation And Conventions

Run npx create-remix@latest and answer prompts about deployment target, TypeScript usage, and Git initialization. Remix scaffolds with a specific structure: app/routes for route modules, app/root.jsx for the document shell, and app/entry.client.jsx and app/entry.server.jsx for client and server entry points.

Nested route conventions use file naming to build the route hierarchy. A file named routes/products.js creates a /products route. Add routes/products.$productId.js for /products/:productId as a child route. The $ prefix marks dynamic segments. Loaders fetch data on the server, actions handle mutations. Both export as named functions from the route module.

Migration strategy follows this staged approach:

1. Assess your project’s dependencies and file structure to identify compatibility issues
2. Create a proof of concept with a single route to validate the migration approach
3. Migrate non-critical components first to build confidence and catch edge cases
4. Migrate CRA-specific code and critical components once the process is proven
5. Complete post-migration testing, optimization, and performance validation

Post-migration activities include thorough testing across all routes and features, performance optimization with code splitting and lazy loading for large component trees, cleaning up unused dependencies from your package.json, and gradual production rollout starting with low-traffic routes or user segments.

Real-world migrations validate the approach. Stripe migrated millions of lines to TypeScript incrementally. Faire transitioned from a single page application to Next.js without downtime. Peerlist moved from ReactJS to Next.js and documented performance improvements. These companies prove you can migrate large applications successfully with the right strategy.

Production Deployment Requirements For React Alternatives

Deployment requirements split along server-rendered versus static lines. Vite and Parcel projects build to static files that deploy anywhere: Netlify, Vercel, GitHub Pages, S3 with CloudFront, or any static hosting. Upload the dist folder contents, point your domain, done. Next.js and Remix require Node.js hosting or services compatible with their server-side rendering requirements. Vercel provides seamless Next.js deployment, but you can deploy to any platform that runs Node like Render, Railway, Fly.io, or AWS with EC2 or Lambda.

CI/CD integration adapts to each tool’s build command and output directory. Vite projects use npm run build and output to dist. Next.js uses npm run build and outputs to .next. Configure your CI pipeline to run the appropriate build command, then deploy the output folder. Memory limits matter. Allocate at least 4GB for Vite production builds to avoid out-of-memory errors. Next.js needs 3–4GB for large applications. Set environment variables in your deployment platform’s dashboard rather than committing .env files.

Hosting platform recommendations by tool:

• Vite: Netlify, Vercel, Cloudflare Pages, GitHub Pages, or any static host with drag-and-drop deployment
• Next.js: Vercel (first-class support), or Node.js platforms like Render, Railway, Fly.io, or self-hosted Node servers
• Remix: Node.js hosting on Vercel, Fly.io, Render, or platforms supporting Express/Polka/Fastify servers
• Parcel: Any static hosting service, same options as Vite
• Rsbuild: Static hosting for client apps, Node.js platforms if using SSR features

Gradual production rollout reduces risk for large migrations. Deploy to a staging environment first for testing. Route a small percentage of production traffic to the new build with feature flags or canary deployments. Monitor error rates, performance metrics, and user feedback. Digital experience monitoring tools track frontend performance and errors. Over 200,000 developers use tools like LogRocket for this visibility. Gradually increase traffic to the new deployment as confidence grows.

Framework Features: Routing And State Management Integration

Single page applications use client-side routing where JavaScript handles route changes without server requests. React Router dominated this approach for years with declarative route definitions in components. Frameworks like Next.js and Remix replaced client-side routing with file-based systems where the directory structure defines routes automatically.

Next.js file-based routing maps files to routes without a routing library. Create pages/about.js and you’ve got an /about route. Dynamic routes use brackets: pages/posts/[slug].js handles /posts/anything. Nested routes follow the folder structure. The App Router in Next.js 13+ adds layouts that wrap child routes, server components for data fetching, and streaming for progressive page loads. You lose React Router’s flexibility to define routes anywhere, but gain automatic code splitting and structured data loading.

Remix takes nested routing further with built-in loaders and actions. Each route module exports a loader function that runs on the server to fetch data before rendering. The component receives data as props through useLoaderData() hook. Actions handle mutations. Form submissions POST to the same route, and the action function processes them server-side. Nested routes run their loaders in parallel, which makes data fetching faster than waterfall requests. The Route actions pattern gives you structured data mutations without useState, useEffect, or custom submission handling.

Vite stays out of routing decisions. Use React Router, TanStack Router, Wouter, or build your own. Vite doesn’t care. This flexibility means you can keep existing routing code during migration or pick a routing library that fits your needs. React Router works the same with Vite as it did with CRA. State management is the same. Redux, Zustand, Jotai, or Context API all work identically across build tools since they’re React features, not build tool features.

Code Splitting And Bundle Optimization Strategies

Next.js handles automatic code-splitting at the route level without configuration. Each page component becomes a separate JavaScript chunk. Import a component in one page, and it only loads for that page. Dynamic imports work for component-level splitting. Use next/dynamic to lazy load heavy components that don’t need to render immediately.

Vite requires manual dynamic imports for code splitting beyond the entry point. Use React.lazy and Suspense for component-level splitting: const HeavyComponent = React.lazy(() => import('./HeavyComponent')). Wrap it in <Suspense fallback={<Loading />}> and Vite creates a separate chunk. Route-based splitting works the same way. Lazy load route components so each route gets its own bundle.

Tree shaking removes unused code from production bundles. All modern bundlers (Rollup for Vite, webpack for Next.js, esbuild for Remix, and Parcel) support it. Import only what you use: import { useState } from 'react' instead of import * as React from 'react'. The bundler eliminates the rest of React from your bundle. Side-effect-free modules get more aggressive tree shaking. Mark them in package.json with "sideEffects": false.

Lazy loading best practices center on splitting at route boundaries first, then component boundaries for heavy widgets. Don’t lazy load components that render immediately on page load. The extra network request slows initial render. Lazy load below the fold, behind user interactions (modals, tabs, dropdowns), or route components users might not visit. Use route-based splitting as the baseline, then add component splitting where it makes sense.

CSS And Asset Handling In Modern React Build Tools

CSS processing works similarly across modern build tools, but with different default setups. All major alternatives support CSS Modules out of the box. Name your file Component.module.css and import it. The build tool scopes class names automatically to prevent conflicts. Sass and SCSS work by installing the dependency and importing .scss files. PostCSS runs for vendor prefixing and modern CSS features, usually without config.

Next.js built-in Image component handles responsive images, lazy loading, automatic format conversion to WebP, and blur placeholder generation. Use <Image src="/photo.jpg" width={500} height={300} alt="Photo" /> instead of <img>. Next.js optimizes at request time, serving the right size and format for each device. Font optimization inlines critical font CSS and preloads font files to eliminate layout shift. Script components control third-party script loading with strategy="lazyOnload" for analytics or ads that don’t need to block rendering.

Vite handles images and fonts through standard imports or the public directory. Import an image and get a URL: import logo from './logo.png'. Vite fingerprints the filename for cache busting. Fonts go in the public folder or get imported as URLs. You handle optimization manually. Use loading="lazy" on images, load fonts with font-display: swap, and control third-party scripts with async or defer attributes. The manual approach gives you full control but requires more setup than Next.js automatic optimizations.

Static asset imports work through standard ES modules across all tools. Images, fonts, JSON, and other assets import as URLs. The bundler processes the import, copies the file to the output directory with a hashed filename, and returns the URL. Public folder conventions differ slightly. Vite and Parcel serve public folders as-is without processing, while Next.js serves the public folder from the root URL path. Put public/favicon.ico and reference it as /favicon.ico in all tools.

Developer Tooling Ecosystem And Plugin Architecture

Vite’s plugin architecture uses Rollup-compatible plugins plus Vite-specific hooks. Most Rollup plugins work with Vite directly. Install @rollup/plugin-legacy and add it to vite.config.js. Vite plugins hook into development server lifecycle, transform code during dev or build, and customize module resolution. The ecosystem includes plugins for React Fast Refresh, legacy browser support, PWA generation, image optimization, and framework-specific features. Community plugins cover most needs without writing custom code.

Next.js configuration uses a JavaScript config file with nested options instead of plugins. Extend with next.config.js options for webpack customization, environment variables, redirects, headers, and feature flags. Official plugins exist for MDX, PWA, and bundle analysis. The plugin pattern is less flexible than Vite. Next.js expects you to work within their configuration structure rather than replacing bundler behavior. This constraint keeps Next.js apps more consistent but limits escape hatches when you need custom build steps.

Essential developer tools and their integration:

• ESLint: All tools support ESLint with config files. Vite and Parcel require manual setup. Next.js scaffolds with ESLint config. Remix includes ESLint in new projects.
• Prettier: Framework-agnostic. Add .prettierrc and eslint-config-prettier to any project. Works identically across all tools.
• Git hooks: Use Husky and lint-staged with any tool. Add pre-commit hooks to run linting and formatting before commits.
• Testing: Jest, Vitest, or React Testing Library work with all tools. Configuration varies. Vitest integrates naturally with Vite, Jest needs more setup.

Ecosystem maturity affects available solutions for edge cases. Next.js has the largest ecosystem with extensive third-party integrations, authentication solutions, CMS adapters, and deployment guides. Vite’s ecosystem grew fast. Most common needs have solutions. Remix’s ecosystem is smaller and newer, which means fewer integrations and libraries. Parcel has the smallest plugin ecosystem but works for most standard React needs without plugins.

Use Case Recommendations For Choosing Your React Tool

Best Tools For Single Page Applications

Vite is the primary choice for single page applications. Fast development server, instant HMR, and simple setup make it ideal for SPAs where server-side rendering doesn’t matter. The development experience beats CRA dramatically without locking you into framework conventions. You control routing, state management, and architecture decisions. Vite works great for developer tooling, internal dashboards, and web applications where SEO isn’t critical.

Parcel works for the simplest SPAs where you want zero configuration. Small personal projects, learning exercises, or quick prototypes benefit from Parcel’s automatic setup. Drop an index.html file, run parcel index.html, and you’re coding. The tradeoff is less control and slower builds on larger projects. Use Parcel when setup time matters more than long-term scalability.

Framework Selection For SEO-Critical Projects

Next.js dominates SEO-critical projects like e-commerce sites, marketing sites, blogs, and content platforms. Server-side rendering means search engines get fully-rendered HTML. Static site generation pre-renders pages at build time for maximum performance. The Image component optimizes for Core Web Vitals. Built-in features like metadata API, sitemap generation, and structured data support make SEO implementation straightforward.

Remix works for progressive web apps and content sites where user experience and accessibility outweigh raw build speed. The server-first rendering ensures content loads fast even on slow connections. Forms work without JavaScript, then enhance when it loads. Choose Remix when you want server-side rendering with progressive enhancement and don’t need Next.js ecosystem size.

Static site generation works with Next.js getStaticProps or build-time rendering in Remix. Pre-render pages at build time, deploy as static files, and get both SEO benefits and static hosting simplicity. This approach works best for content that changes infrequently: blogs, documentation, marketing sites.

Rapid Prototyping And Learning Projects

Vite wins for learning React and building prototypes. The fast feedback loop helps learning. Make a change, see results instantly. No configuration overhead means focusing on React concepts instead of build tools. The npm create vite@latest command gets you from idea to code in 30 seconds.

Parcel simplifies even further for absolute beginners. Zero configuration means no vite.config.js to understand. Point Parcel at an HTML file and it handles everything. This simplicity helps when you’re learning React fundamentals and don’t want build tool complexity. The limitation is you’ll eventually outgrow Parcel and need to migrate to Vite or a framework.

The tradeoff between simplicity and features matters for learning progression. Start with Parcel if configuration files intimidate you. Move to Vite when you understand React and want more control. Graduate to Next.js or Remix when you need to learn server-side rendering and full-stack patterns. Each step adds capability at the cost of simplicity.

Common Migration Challenges And Solutions

Most migration pain happens at the configuration boundary, not in React components. Environment variable handling changes across tools, which breaks API keys and feature flags. Proxy configuration for development API calls works differently. Import paths and module resolution can break if you used CRA’s built-in path aliases.

Environment variables shift from process.env.REACT_APP_API_KEY in CRA to import.meta.env.VITE_API_KEY in Vite. Next.js uses process.env.NEXT_PUBLIC_API_KEY for client-side variables. Find all references to environment variables and update the prefix and access pattern. Public variables need the tool-specific prefix. Server-only variables (in Next.js and Remix) use process.env without prefix.

Common migration issues with solutions:

1. Environment variables: Replace REACT_APP_ prefix with tool-specific prefix (VITE_, NEXT_PUBLIC_). Update access from process.env to import.meta.env in Vite. Move .env files to root and verify variable names.
2. Import paths: Replace CRA’s implicit path aliases with explicit configuration. Add resolve.alias in vite.config.js, or paths in tsconfig.json for TypeScript. Use relative imports if path aliases cause issues.
3. Build scripts: Replace react-scripts commands in package.json. Update start to vite or next dev. Change build to vite build or next build. Add preview script for local production testing.
4. Routing: Convert React Router to file-based routing in Next.js or Remix. Move route definitions from components to file structure. Refactor route parameters from :id syntax to [id] file naming. Update data fetching from useEffect to loaders or getServerSideProps.

Final Words

Create React App is dead, and your React projects need modern alternatives now.

Vite delivers the fastest dev experience for most teams. Next.js handles server-side rendering and SEO-critical sites. Remix excels at progressive web apps. Parcel works for quick prototypes.

Pick based on your project type. SPAs? Go Vite. E-commerce or content site? Choose Next.js. Building a PWA? Try Remix.

The migration is straightforward—most component code stays the same, just the build config changes.

Stop fighting deprecated tools. Switch to a create react app alternative that’s actually maintained, and ship faster.
