Frequently Asked Questions
- What's the difference between React and React Native?
- React is for building web applications that run in browsers. React Native is for building mobile apps for iOS and Android. They share similar concepts and syntax, but target different platforms. We're experts in both.
- Can you improve the performance of our existing React app?
- Yes, we regularly optimise React applications. Common improvements include code splitting, lazy loading, memoisation, state management optimisation and bundle size reduction. We start with profiling to identify the biggest opportunities.
- Do you use TypeScript with React?
- Yes, we use TypeScript on virtually all React projects. TypeScript catches errors earlier, improves code documentation and makes refactoring safer. It's especially valuable as applications grow larger.
- Can you help build a design system or component library?
- Yes, we build reusable component libraries using tools like Storybook. A well-designed component library speeds up development, ensures consistency and makes it easier to maintain your applications as they grow.
- How do we get started on a React project?
- Book a free consultation to discuss your requirements. We'll help determine the right technical approach - whether that's Next.js, a single-page app, or integrating React into an existing system. For larger projects, an App Planning Day helps define scope and architecture.
