Our Approach

How we actually
build with React

React is simple to start and easy to get wrong at scale. The decisions that matter happen before the first component is written.

Next.js or plain React — by need, not default

Next.js when server-side rendering, SEO, or a built-in API layer matter. Vite-powered plain React when you're building an internal tool or dashboard where SEO is irrelevant and build speed matters more.

State management sized to the problem

Context API for simple shared state. Redux Toolkit or Zustand when the application genuinely has complex, cross-cutting state. We don't reach for a state library because it's trendy.

Component architecture that scales

Clear separation between presentation and logic, typed props with TypeScript, and a component structure that a new developer can understand without a walkthrough.

Performance as a default, not an afterthought

Code splitting, memoization where it actually helps, and Lighthouse scores checked during development — not discovered as a problem after launch.

What We Build

React development
services we deliver

01

React Apps From Scratch

New product builds, internal tools, and customer-facing applications architected from a clean slate.

02

Migration to React

Moving off jQuery, Angular, or an aging legacy frontend onto a modern React codebase, incrementally if needed.

03

Dedicated React Team

A senior React developer or full team embedded in your project, working exclusively on your codebase.

04

Next.js & SSR

Server-rendered React applications for content-heavy and SEO-sensitive products that still need app-like interactivity.

05

React UI/UX Implementation

Pixel-accurate builds from Figma designs, with the component structure planned out before development starts.

06

Maintenance & Support

Dependency upgrades, React version migrations, bug fixes, and ongoing feature development after launch.

Why CrestCoder

Real React depth,
not a buzzword

No over-engineering

We size the architecture and tooling to the actual project — not every app needs Redux, microservices, or a monorepo.

Code the next developer can read

Typed components, clear naming, and documentation — so your team or the next vendor isn't starting from zero.

Full project visibility

Two-week sprints with a working demo at the end of each — you see real software, not slide decks.

Full-stack when you need it

We commonly pair React with Node.js or Laravel — happy to build just the frontend if you already have a backend team.

How We Work

Our React
development process

Five stages from first call to a maintained, live product.

01

Discovery & architecture planning

We review requirements and decide on Next.js vs plain React, state management approach, and overall component structure before writing code.

02

UI/UX design

Figma designs validated against real user flows, with the component breakdown mapped out alongside the visual design.

03

Agile development

Two-week sprints with a working demo at the end of each, deployed to a staging environment you can access anytime.

04

Testing & QA

Component and unit tests with Vitest or Jest, end-to-end coverage with Playwright on larger applications.

05

Launch & support

Production deployment, then an optional monthly retainer for dependency upgrades and continued feature work.

Common Questions

Frequently
asked questions

Still have questions? Contact us directly.

Why choose React over Angular or Vue for my project?+
React is our most common recommendation because of its huge ecosystem, deep hiring pool, and flexibility for complex, interactive UIs. It is not always the right choice — Angular suits large enterprise teams that benefit from more structure, and Vue suits teams wanting a gentler learning curve. We will give you an honest recommendation based on your team and project during the discovery call.
Do you use Next.js or plain React?+
Both, depending on the project. We use Next.js when server-side rendering, SEO, or a built-in routing and API layer matter — common for marketing sites and content-driven products. We use plain React with Vite for internal tools, dashboards, and SPAs where SEO is not a concern and build speed matters more.
What state management approach do you use in React?+
It depends on the complexity of the application. For simpler apps, React's built-in Context API is often enough. For larger applications with complex shared state, we typically use Redux Toolkit or Zustand. We avoid over-engineering state management for projects that do not need it.
Can you take over an existing React codebase?+
Yes. We regularly take over React projects built by other agencies or in-house teams. We start with a technical audit covering component structure, dependency health, and any performance issues, then continue development from there with a clear report of what we found.
Do you build the backend API as well, or just the React frontend?+
Most of our React projects are full-stack. We commonly pair React with a Node.js or Laravel backend, but we are equally happy to build just the frontend and integrate with an API your team or another vendor maintains.
How do you handle testing for React applications?+
We use Vitest or Jest with React Testing Library for component and unit tests, and Playwright for end-to-end testing on larger applications. The level of test coverage is scoped during discovery based on how critical the application is and your long-term maintenance plans.
