React Website Development
The library behind every interface we build.
LGTCS builds websites and portals with React, the interface library used by Meta, Netflix and the BBC. Reusable components, accessible markup.
Fixed-price packages from $300. No retainer, no licence fees.
Short answer
React is a library for building user interfaces out of reusable pieces called components. A navigation bar, a donation form or a results table is written once and used everywhere it is needed, so a change to it changes every page at the same time. LGTCS uses React through Next.js on every project, from a single landing page to a full member portal. It is the most widely used interface library on the web, which means the code we write can be maintained by any competent developer, not only by us.

What React actually is
React breaks an interface into components. A button, a card, a form, a navigation bar. Each is written once and then used wherever it is needed. When the donation button has to change, it changes in one file and every page that uses it updates at once. On a hand-built site, the same change means finding every page that contains that button and hoping none were missed.
That property is worth the most on the sites that live longest. A ten-page website with a consistent header, footer, card style and form style is not ten pages of code. It is a set of components and ten short files describing which components go where. Two years later, when somebody wants the heading style changed, the work is small and the risk is low.
React is also the most widely used interface library on the web, which matters commercially rather than technically. It means there is a large pool of developers who can read your code, a deep supply of solved problems when something unusual comes up, and no realistic prospect of the library being abandoned. Choosing a niche framework can be the right call technically and still leave you unable to hire anyone to maintain the result.
React components versus a page-builder template
Page builders are genuinely good at getting something online quickly. The difference appears later, when the site has to change, grow or be handed to somebody else.
| Aspect | React components | Drag-and-drop page builder |
|---|---|---|
| Changing one element everywhere | Edit one component | Edit every page that uses it |
| Design consistency | Enforced by shared components | Depends on whoever built each page |
| Page weight | Only the code the page needs | The builder's runtime on every page |
| Custom functionality | Anything you can describe | Whatever the plugin library offers |
| Where the site can be hosted | Anywhere | Usually only on that platform |
| Getting started | Slower, needs a developer | Faster, no developer needed |
The last row is a real advantage for page builders, and we will not pretend otherwise. If you need a simple site live this week, you have no budget for a developer, and you do not expect it to grow, a page builder is the sensible answer and LGTCS will tell you so. React earns its cost on sites that have to keep changing for years.
How LGTCS uses React on client projects
Specific decisions we make on real builds, not a feature list copied from the documentation.
A component library specific to your site
Buttons, cards, forms, tables and navigation are built once as a set that matches your brand. Every new page is assembled from pieces that already look right, which is why a site's tenth page takes a fraction of the time the first one did.
Server Components keep pages light
React 19 lets most of a page render on the server and ship as plain HTML, with JavaScript sent only for the parts that genuinely need to react to a click. A content page carries almost no JavaScript at all, which is the single biggest factor in how quickly it loads on a phone.
Accessible markup by default
Components are written with correct heading levels, labelled form fields, keyboard navigation and visible focus states. Building accessibility into the shared components means it is present on every page rather than retrofitted onto the few that get audited.
Forms that behave properly
Validation as somebody types, clear error messages next to the field at fault, and a submit button that cannot be pressed twice. On a donation form, each of these is the difference between a completed gift and an abandoned one.
Interactive pieces where they earn their place
Filterable project lists, searchable document libraries, multi-step application forms, dashboards. These are the parts of a site that cannot be static, and they are what React was designed for.
Code written to be handed over
Clear component names, small files, and structure a developer who has never met us can follow. Because React is so widely known, handover does not require finding a specialist in something obscure.

How a React project runs, step by step
The same sequence on every project, whether it is a single landing page or a full platform.
- 1
Design the component set first
Before pages are built, we agree the pieces: how a card looks, how a button behaves, what a form field does when it is wrong. Deciding this once prevents a site that drifts as it grows.
- 2
Build the shared components
The reusable set is built and checked on its own, including keyboard use and screen-reader behaviour, before any page depends on it.
- 3
Assemble the pages
Each page is composed from existing components. Pages stay short and readable, which is what makes later changes quick and safe.
- 4
Decide what runs in the browser
Every interactive piece is a deliberate choice, because each one adds JavaScript that a visitor has to download. Anything that can render on the server does.
- 5
Test on real devices
Checked on phones and tablets, with a keyboard, and at large text sizes. A layout that only works on a developer's monitor is not finished.
- 6
Document the components
A short written guide to what each component is for and how to use it, so the next developer extends the set rather than starting a competing one.

Projects we build with React
The kinds of work this part of the stack is genuinely the right answer for.
Sites that will keep growing
When pages get added regularly, a shared component set means page twenty costs a fraction of page one and still looks identical to it.
Portals and dashboards
Anything where the screen changes in response to the person using it, rather than simply presenting fixed content.
Organisations with strict brand guidelines
Components enforce the brand structurally. Nobody can accidentally publish a page with the wrong button or the wrong heading size.
Teams that expect to change developer
React is the most widely known interface library on the web, so the pool of people who can maintain your site is as large as it gets.
The business reason we chose it
Technology decisions only matter if they change something you can measure.
Changes stay cheap as the site grows
A design change touches one component rather than thirty pages, so maintenance cost does not climb with page count.
Pages stay fast
Server Components mean a content page ships almost no JavaScript, which is what visitors on ordinary phone connections actually feel.
You are not dependent on us
Conventional React in your own repository can be picked up by any competent developer. That is deliberate.
In our packages
Used on every package, from Launch upward. Interactive features such as filtering, search and multi-step forms scale with the package.
See all four packages side by sideReact questions we get asked
The things clients actually ask before signing, answered plainly.
Is React overkill for a small website?
Sometimes, and LGTCS will say so when it is. For a genuinely static one-page site that will never change, simpler tools exist. The reason we still use React through Next.js on small builds is that the pages render to plain HTML anyway, so there is no speed penalty, and the moment the site grows to five or ten pages the shared components have already paid for themselves. If your project truly is one page forever, tell LGTCS and we will recommend the cheapest thing that works.
Does React make websites slow?
It can, when everything is pushed into the browser. That is a decision about how a site is built, not a property of React. LGTCS renders pages on the server with React Server Components and sends JavaScript only for parts that genuinely need to respond to a click, so a content page arrives as HTML and carries almost no JavaScript. Built that way, React sites are among the fastest on the web.
Is React good for SEO?
Yes, when the pages are rendered ahead of time rather than assembled in the browser. The old criticism came from single-page applications that shipped an empty page and filled it with JavaScript, which search engines handled poorly. Every site LGTCS builds renders complete HTML before it reaches the visitor, so crawlers and answer engines see the full content immediately.
What is the difference between React and Next.js?
React is the library for building the interface. Next.js is the framework around it that handles routing, rendering, and how the site is built and deployed. React on its own does not decide what a URL does or how a page reaches a visitor. LGTCS uses them together on every project, which is the standard combination.
Will I be locked into LGTCS if my site is built in React?
No, and this is one of the reasons we chose it. React is the most widely used interface library on the web, the code sits in your own GitHub repository, and we write it in conventional patterns with documentation for the next person. Changing developer means granting someone access. Ask LGTCS to walk you through the repository before handover and you will see exactly what you are getting.
Can LGTCS rebuild my existing site in React?
Yes, and rebuilds are regular work for us. We start by looking at what you have, what content needs to move, and which parts are worth keeping as they are. Send LGTCS your current web address and we will come back with an honest view of whether a rebuild is worth the money, or whether improving what you already have would serve you better for less.
Is React accessible for screen-reader users?
React does not make a site accessible or inaccessible on its own, but building with components makes doing it properly far more achievable. Correct heading structure, labelled fields, keyboard navigation and focus states are built into the shared components once, so every page inherits them instead of each page being audited separately.
The rest of the stack
Every tool we use has to work with the others. These are the closest neighbours.
