Why MagmaLabs for React
Most React apps slow down because of structure, not the framework. We build for the codebase you will have in three years.
02
Components that scale
Shared component libraries with Storybook and accessibility baked in, so new screens get faster to build, not slower.
03
Full stack, one team
The same engineers write the APIs and data layer, in Node or Rails, so the frontend never waits on another vendor.
04
TypeScript and tests
Strict TypeScript, Vitest, React Testing Library and Playwright in CI from week one. Refactors stay safe.

FAQ

When should I use React instead of Next.js?
Plain React with Vite is the right fit for apps that live behind a login: dashboards, admin tools, internal platforms and complex editors where SEO does not matter and your backend already exists. If you need server rendering, search visibility or a full stack framework, we recommend Next.js and build that instead.
Can you modernize our legacy React codebase?
Yes. We move class components to hooks, Create React App to Vite, JavaScript to TypeScript and Redux boilerplate to Redux Toolkit or TanStack Query, one module at a time. Your team keeps shipping features while the codebase improves underneath.
Can you migrate from Angular, Vue or jQuery to React?
Yes. We run the old and new UI side by side and replace screens incrementally, so there is no big bang rewrite and no feature freeze. Every migration starts with an audit to scope risk and timeline.
Do you build design systems and component libraries?
Yes. We build accessible component libraries in React and TypeScript with Storybook, visual regression tests and documentation, published as a package your teams can share across products. Our UX/UI designers can own the Figma side too.
How do you handle state management?
We pick the lightest tool that fits. Server data goes through TanStack Query, local state stays in components, and Zustand or Redux Toolkit come in only when shared client state genuinely needs them.
Can your React engineers join our existing team?
Yes, that is most of what we do. Through Team Embed, senior React engineers join your Slack, standups and repo, follow your conventions and work U.S. hours. Most start within 1 to 3 weeks.
How much does React development cost?
React engineers through Team Embed start at $8,500 per engineer per month. MVPs, typically 4 to 8 weeks, and rebuilds, typically 3 to 6 months, are quoted as a fixed price after scoping. If your app was built fast or with AI tools, the Production Readiness Audit is a fixed $4,900.
Do you use TypeScript and automated tests?
Yes. Every React project we start is strict TypeScript, with Vitest and React Testing Library for components and Playwright for end to end flows, all running in CI from week one.
