Front-end library
React development
React is where much modern interface work starts. It breaks a screen into reusable parts that update themselves when data changes. We use it for applications that people work in for hours, and we say so when a lighter tool would serve better.

At a glance
What it is
React is a widely used library for building interactive screens from small reusable parts, and it sits behind many web applications and dashboards.
Problems it solves
Interfaces with many moving parts become hard to change and easy to break when they are built page by page.
Who it suits
Teams building an application with a lot of interaction, and technical leads choosing or inheriting a front-end stack.
How to choose
Choose React when the interface is complex and will keep changing. Choose something lighter when the site is mostly reading.
What it means
Interfaces built from parts
React is a JavaScript library for building user interfaces from components. You describe what a screen should look like for the current data, and React updates the page when the data changes.
The practical benefit is reuse and predictability. A table or a form is built once and used everywhere, so a change in one place appears everywhere, and screens behave the same way.
React on its own handles only the interface. The decisions around it, such as routing, data, and hosting, are usually made by adding a framework like Next.js, or by assembling the pieces directly.
What DECHY can do
Where we use React
Applications
- Internal tools and operations screens.
- Customer portals with accounts and history.
Dashboards
- Live views of orders, jobs, and stock.
- Tables with search, filters, and exports.
Product interfaces
- The screens of a software product.
- A design system built once and reused.
Rescue work
- Untangling an application that is hard to change.
- Adding tests where none exist.
How we structure it
From design to working screens
A tidy React project starts from the design, not from the code.
From design to working screens
A sequence of 5 steps. Design system: Agreed colors, type, and spacing.; Component library: Reusable parts built once, in isolation.; Screens: Assembled from those parts.; Data connection: Screens linked to the services behind them.; Checks: Automated tests, then review with real users..

Where it fits
React or something lighter?
Usually a good fit
React.
- Why
- Many interacting parts, and screens that update as data changes.
Usually a good fit
A framework that builds pages ahead, or a content platform.
- Why
- Less code sent to the visitor, and simpler upkeep.
Usually a good fit
A hosted site builder.
- Why
- Cheaper to run than a custom application.
Typical uses
Systems that suit React
An operations dashboard
Jobs, stock, and schedules on live tables that update as work is done, used by staff all day.
A booking or scheduling tool
Calendars, availability, and forms that respond instantly as people choose.
A customer account area
Orders, invoices, and settings in a consistent, quick interface.
The front end of a software product
Screens built from a shared component library so new features look and behave like the rest.
Choosing the right approach
When React is more than you need
React adds a build process, a set of conventions, and developers who know it. For a small brochure site or a form on a page, that is overhead you will pay for every year.
We will say so early. Sometimes the right answer is a content platform, or a lighter framework, and React earns its place only where the interface is genuinely complex.
Common questions
Questions about React
Is React a framework?
Strictly it is a library for the interface. A framework such as Next.js adds routing, data loading, and page building around it. Most business projects use one.
Will it work for search visibility?
A React application built only in the browser can be hard for search engines to read. A framework that prepares pages ahead of time solves that, which is why we usually pair them.
Can you take over our existing React code?
Yes. We start with a short review of structure, tests, and dependencies, then tell you whether to improve it or rebuild parts of it.
Do we get a design system?
If you want one. We recommend a small one for any application with more than a handful of screens.

Technical depth
How we build with React
The detail a technical reviewer will ask about: language and tooling, state and data, and quality.
We write React in TypeScript, so mistakes in how data is passed between components show up while writing, not in production.
- Local state for what one component owns, and a shared store only where several screens genuinely need the same data.
- A data-fetching layer that handles loading, errors, and caching in one place.
- Forms with clear validation and helpful error messages.
- Component tests for behavior, and a small number of end-to-end tests for the journeys that matter.
- Keyboard and screen reader checks on every shared component.
