Questions

What can you build with React?

Web apps and SaaS products, customer and staff portals, dashboards and admin panels, booking and e-commerce front ends, progressive web apps, and Android and iOS apps with React Native.

Which React version and tools do you use?

The latest stable React with TypeScript, built with Vite or Next.js. Create React App is no longer maintained, so we move older projects off it as part of an upgrade.

Can a React site rank well on Google?

Yes, when it's rendered on the server. For public, SEO-critical pages we use Next.js, with proper titles, structured data and fast Core Web Vitals.

Can you move our existing app to React?

Yes, from jQuery, AngularJS, Vue or older React. We assess the code first, then migrate in stages so the app keeps working throughout.

How do you handle state management?

As simply as the app allows: React's own hooks and context for most screens, TanStack Query for server data, and Redux Toolkit or Zustand when shared state gets complex.

How long does it take?

A simple React app or website typically takes 3 to 5 weeks, a medium-complexity app 6 to 10 weeks, and large applications 3 to 6 months or more. Your proposal has the timeline, and you see demos every sprint.

How do you test React apps?

Unit tests with Vitest or Jest, component tests with React Testing Library, and end-to-end tests with Playwright for the key user journeys.

How much does it cost?

Every project gets a written proposal after a free call: scope, milestones and one fixed price, plus 18% GST. Payment is usually 40% to start and 60% on delivery; larger projects are split into milestones.

Do you provide hosting?

No. We don't sell hosting. Your app runs on hosting or a server in your name; we help you choose it, set it up and deploy for you.

Do you support the app after launch?

Yes: React upgrades, bug fixes, security updates and new features, by the hour or on a monthly plan.
