React JS is Meta's open-source library for building component-driven user interfaces with a declarative, unidirectional data-flow model.
UpWve Technologies delivers React applications for SaaS dashboards, admin panels, marketing sites, and enterprise platforms — TypeScript-first, React 19-ready with Actions and the React Compiler, and tested for accessibility, performance, and Core Web Vitals on real devices.
Our React JS tech stack
The React ecosystem we ship production apps with.
Our React JS development services
SaaS front-ends, dashboards, admin panels, design systems, and legacy modernizations — React work at every scale.
SaaS & Dashboard Front-Ends
Complex data-heavy React apps — multi-tenant dashboards, admin consoles, analytics platforms — with TanStack Query caching, virtualization, and Suspense streaming baked in.
Design Systems & UI Kits
Reusable component libraries in React + TypeScript, built on Radix UI primitives with Tailwind, documented in Storybook, and published as internal packages or npm releases.
React MVP Development
Focused React MVPs — 6-to-10-week engagements from concept to live product, with proper auth, payments, and monitoring from day one.
Legacy to React Migration
Migration from AngularJS, jQuery, Knockout, or older React codebases to modern React 19 + TypeScript. Done page by page so the legacy app keeps shipping.
Internal Tools
Admin panels, back-office workflows, and ops dashboards — often paired with Odoo, ERPNext, Retool, or custom GraphQL / tRPC backends.

Clear Ownership & Long-Term Maintainability
Codebases, documentation, and architectures are built for clarity, handover, and long-term evolution — not dependency on vendors.
React app cost is quoted per project and depends on features, data model, integrations, and performance requirements. We tailor the scope to your budget — MVP, mid-scope SaaS, or enterprise platform. Written estimate within 48 hours, free, with no obligation.
MVP React apps typically ship in 6–10 weeks. Mid-scope SaaS front-ends run 10–16 weeks. Enterprise multi-role dashboards 16–24 weeks. You see a running staging environment by the end of week three.
Vanilla React (Vite) is great for internal tools and SPAs where SEO doesn't matter. Next JS is better when you need SEO, SSR, server components, or tight integration with a content layer. We'll recommend based on your use case.
Default is Zustand + TanStack Query — server state separated from client state. Redux Toolkit for larger teams with established Redux patterns. Jotai for fine-grained atomic state. We avoid Redux for simple apps.
Yes, TypeScript is the default on every new React project we start. Strict mode, zero-any tolerance in domain code, and typed API layers via Zod, tRPC, or OpenAPI codegen.
Yes. We migrate from AngularJS, Knockout, jQuery, and older React class-component codebases to modern React 19 + TypeScript — typically page by page so production keeps shipping.
WCAG 2.2 AA from day one — semantic HTML, keyboard-first, focus management, screen-reader testing, and ARIA where needed. Automated with axe-core in CI and manual testing per release.
Yes. We target LCP < 2.5s, INP < 200ms, and CLS < 0.1 on real devices. Bundle splitting, route-level code splitting, React Compiler, image optimization, and edge caching are standard.
Vitest for unit and integration tests, Testing Library for component tests, Playwright for end-to-end flows, and Storybook for visual regression. Every PR runs the suite in CI.
Yes. Vercel AI SDK for streaming chat, LangChain.js for RAG, typed tool schemas via Zod, and generative UI patterns with React Server Components. Hybrid frontier API plus your own backend is our default.
Yes. 90 days of monitoring with P1 fixes inside 72 hours, followed by an optional monthly retainer covering React version upgrades, dependency hygiene, and feature iterations.
You do. Full IP assignment on invoice — source, design system, Storybook, CI/CD, and every component we write for your project.
