Vite development company
Teams leaving Create React App, Vue CLI, or webpack use our Vite development services to migrate safely, add custom plugins, and set up SSR or library builds, with the dev server and production output kept in agreement.

Fast tooling without dev and build drift
Choosing a Vite development company makes sense when a frontend needs to leave Create React App, Vue CLI, or an aging webpack setup, or when an existing Vite project has outgrown its default config, and Krapton handles all of those cases. Vite serves source files as native ES modules in development and pre-bundles dependencies once, so the dev server starts quickly and hot updates stay fast as the app grows. Production builds go through a separate bundler, Rollup and increasingly the Rust-based Rolldown, which is why our engineers test the built output and not just the dev server. Vite is not automatically the answer: apps built around webpack-specific loaders or a mature Module Federation setup may be better served by Rspack. Common problems in this work include CommonJS dependencies that need optimizeDeps entries, secrets exposed through the VITE_ prefix, SSR externalization errors, and wrong base paths for subdirectory deployments.
Vite development services
CRA to Vite migration
react-scripts replaced with Vite and @vitejs/plugin-react, index.html moved to the project root, REACT_APP_ variables renamed, and Jest swapped for Vitest where that simplifies testing.
Vue CLI and webpack moves
Vue CLI or custom webpack projects migrated by mapping loaders to plugins, aliases to resolve.alias, and proxy rules to server.proxy, with both builds running until their output matches.
Custom Vite plugins
Plugins built on Rollup-compatible hooks plus Vite-specific ones such as configureServer and transformIndexHtml, for code generation, virtual modules, internal assets, or backend integration.
SSR and framework setup
Server-side rendering through Vite’s SSR APIs or frameworks built on Vite, such as SvelteKit, Nuxt, Astro, and React Router, including externals, streaming, and deployment adapters.
Library and design system builds
Library mode builds that emit ESM, type declarations, and per-component CSS, with package.json exports set up so consumers tree-shake only what they import.
Backend-integrated frontends
Vite wired into Laravel, Rails, or Django through the build manifest, with hot updates in development and hashed assets served by your backend in production.
Why teams choose Krapton for Vite
Senior engineers, fixed scope, and code you own — the things agencies promise and rarely deliver.
Production output is tested
The dev server and the production bundle are produced differently, so end-to-end tests run against vite build plus vite preview, catching issues that never appear in development.
Environment variables audited
Only variables with the VITE_ prefix reach client code, and anything given that prefix ships to every browser, so env files are reviewed for secrets during each migration.
Dependency quirks handled properly
CommonJS packages, linked monorepo packages, and libraries touching Node.js globals get explicit optimizeDeps or SSR settings instead of trial-and-error edits to the shared config.
Upgrades tracked across majors
Vite moves quickly, raising its Node.js baseline and default browser targets between majors, so every upgrade comes with a checked list of breaking changes and plugin compatibility.
How a Vite project runs with Krapton
01
Toolchain inventory
Every loader, plugin, environment variable, alias, and test tool in the current build is listed, then mapped to a Vite equivalent or flagged as a gap.
02
Parallel build branch
Vite runs beside the existing toolchain on a branch, and CI builds both, comparing bundle contents, routes, and test results until they agree.
03
Cutover with fallback
The default build switches once parity is proven, and the old configuration stays for one release, so rollback is a single revert if something slips.
04
Cleanup and docs
Old loaders, polyfills, and scripts are removed, the Vite config gets comments explaining each choice, and your team receives notes on adding plugins safely.
The Vite stack we build with
Vite development: questions answered
Is a Vite development company only about build configuration?
No. Configuration is the visible part, but the work usually includes migrating projects from Create React App, Vue CLI, or webpack, writing custom plugins, configuring SSR and library builds, integrating Vite with backend frameworks, and keeping upgrades and plugin compatibility under control. A Vite development company should leave you with a fast dev server, a production build you can trust, and configuration your team understands.
Is it worth migrating from Create React App to Vite?
Yes, for most apps. Create React App has been officially deprecated by the React team, so staying means accumulating outdated dependencies and security warnings. Vite offers faster startup, quicker hot updates, and a maintained plugin ecosystem. The effort depends on how far the app strays from defaults: ejected configs, custom Babel plugins, and Jest-specific test setups all add work, and complex apps benefit from a parallel build first.
Why does our app work in the Vite dev server but break in production?
Because development and production use different pipelines. The dev server serves unbundled ES modules transformed on demand, while the production build bundles everything, applies tree shaking, and handles CommonJS differently. Typical causes are circular imports, side-effect imports that get dropped, CommonJS interop differences, dynamic imports with variable paths, and environment variables read at runtime instead of build time. Testing the built output in CI prevents this class of bug.
Can Vite handle a large monorepo?
Yes, with some care around linked packages and module counts. In pnpm or npm workspaces, linked packages may need optimizeDeps or dedupe settings, barrel files can make the dev server request hundreds of modules per page, and server.warmup helps heavy entry points. Nx or Turborepo add task caching across packages, and Vitest’s multi-project configuration keeps tests consistent across the repository.
What makes one Vite migration bigger than another?
Distance from Vite’s defaults is the main factor. Effort rises with custom webpack loaders that need plugin equivalents, the number of apps and packages in a monorepo, SSR requirements, legacy browser support, test suites moving from Jest to Vitest, and backend integration. Krapton inventories the toolchain before quoting, so the estimate reflects what is actually in your repository.
