Hire a ReactJS Developer — TypeScript-First, Ships on Time

React and React Native are both maintained by Meta, share the same component model and hooks API, and are written in JavaScript/TypeScript. The difference is where they render. React (often called ReactJS) renders to a browser DOM — it produces web pages and web applications. React Native renders to native platform UI components — it produces iOS and Android mobile applications. React Native does not use HTML or a browser; it maps React components to platform-native widgets (UIView on iOS, View on Android). A ReactJS developer and a React Native developer have overlapping skills in JavaScript and component thinking, but they work in different environments with different tools, different debugging workflows, and different platform constraints.

Yes, as a default. TypeScript is not optional for us on any new React project. It catches type errors at compile time rather than in production, makes component props self-documenting without JSDoc comments, enables safe refactoring with IDE support, and serves as a contract between the components a developer writes and the ones their colleagues consume. For existing JavaScript codebases we can manage incremental TypeScript adoption — adding strict typing to new components and high-risk areas before migrating the rest.

The state management choice depends on what the application actually needs. We use React Query (TanStack Query) for any state that comes from a server — API data, pagination, cache invalidation. We use Zustand for lightweight client-side global state where a simpler alternative to Redux is appropriate. We use Redux Toolkit for large applications with complex state interactions where the reducer pattern and DevTools debugging justify the boilerplate. We do not use Context API as a state management tool for anything that changes frequently — it is the right choice for stable config (theme, auth user), not for application state.

A standard SPA with 10–20 views, a design system, and an API integration: 8–12 weeks with a single dedicated developer. A complex dashboard with real-time data, rich data visualisation, and 30+ views: 12–20 weeks. A component library with Storybook, accessibility compliance, and design token integration: 4–8 weeks as a standalone deliverable. These timelines assume the design is finalised before development starts — design in parallel with development reliably extends timelines by 30–50%.

Yes — most of our React engagements are embedded in an existing engineering team. The developer joins your Slack, your Git repository, your sprint ceremonies, and works to your team's code standards. We ask for a code standards document or an example of existing code in the first week so the work is consistent with what is already there, not a stylistically different island in the codebase.
