Web development · React

React development for the parts no template covers.

React is how most interactive interfaces on the web are built now, including WordPress’s block editor and the code components in Webflow. Our React development covers custom frontends and dashboards, admin tools for your team, interactive pieces embedded in an existing site, and editor blocks for WordPress. It is AI-assisted development: AI tools draft the routine code, and a developer with a WordPress and PHP background since 2021 designs it, reviews every change and owns the result.

Fit

Who it’s for

  • Businesses that need a dashboard, portal or admin tool built around their own data
  • Sites that need one interactive piece: a configurator, a calculator, a quiz, a booking widget
  • WordPress sites that want custom editor blocks, and Webflow sites that want code components
  • Teams with a React app that needs fixes, new features or someone to take it over

Not the right fit for native mobile apps or large products that need a full-time engineering team. For complete sites and storefronts in React, see our Next.js development page.

Problems we fix

Where React projects go wrong.

  • 01

    A whole app for one widget

    A full single-page app built where one small embedded component would have done the job.

  • 02

    No framework, no plan

    A hand-rolled React setup that slowly reinvents routing, data loading and builds.

  • 03

    Slow on phones

    Large bundles and too much JavaScript, so the page looks ready but doesn’t respond to taps.

  • 04

    Inaccessible components

    Custom dropdowns, modals and tabs that can’t be used with a keyboard or screen reader.

  • 05

    State everywhere

    Data fetched and stored in many places, so bugs appear when two parts of the screen disagree.

  • 06

    Abandoned dependencies

    Old build tools and libraries nobody updates, until an upgrade becomes a rewrite.

Before we change anything, we check five things.

A short animated walk-through of the first checks in our audit. No sound needed: everything is on screen, and the transcript is below.

What we check first in a React project, an animated explainer of 1:10 with on-screen captions and controls to pause.

Read the transcript
  1. What we check first in a React project Five checks, from the size of the app to who keeps it updated.
  2. 1. Does it need to be a whole app? A full single-page app for one calculator ships far more code than one embedded component would. (Example page.)
  3. 2. Framework or homemade? A hand-rolled setup slowly rebuilds routing, data loading and builds. The React team recommends starting with a framework. (Example app. Source: react.dev, “Creating a React App”.)
  4. 3. Does it respond to taps on phones? Too much JavaScript makes a page look ready but ignore taps. Google’s “good” INP is within 200 ms. (Example app, real-visitor data. Thresholds: Google Search Central.)
  5. 4. Can it be used with a keyboard? WCAG asks for every function to work from a keyboard. Custom dropdowns, modals and tabs often fail it. (Example components. Source: WCAG 2.2, 2.1.1 Keyboard.)
  6. 5. How old are the dependencies? Libraries nobody updates turn the next upgrade into a rewrite. (Example app.)
  7. Then we fix them, in that order. Want this checked on your site? The free growth audit covers all five, in writing.

Our approach

React development sized to the job.

The first decision is how much React a project needs. React’s own guide, Creating a React App, recommends starting a new app with a framework such as Next.js or React Router, and building from scratch only when a project has constraints those frameworks don’t serve. We follow that advice: full sites and storefronts go to Next.js, and a single interactive piece on an existing site stays a small component.

Kind one is custom frontends and dashboards: a customer portal, a reporting dashboard on top of your store or CRM data, a quote builder, a booking flow. These are built in React with TypeScript, a clear data layer and an API behind them, often a Node.js backend we write too.

Kind two is admin tools for your team: bulk editors, review queues, import screens and other tools that save hours of copy and paste. WordPress admin screens and standalone internal tools can both be built with React components, so your team gets an interface designed for the job instead of a spreadsheet.

Kind three is components embedded in sites you already have: a product configurator on a Shopify theme, a calculator on a WordPress page, a quiz on a landing page. Webflow’s code components are React components that designers can place on the canvas with props and slots, and we build those for Webflow sites too. The component loads only where it is used, so the rest of the site stays fast.

Kind four is WordPress blocks. WordPress’s block editor is written in React, and custom blocks are React components registered with WordPress. This website’s editor uses our own blocks for every section, which is the same skill applied to your site. Our custom WordPress page explains when custom blocks are worth it.

AI-assisted development makes React work faster and cheaper than it used to be. AI tools draft components, forms and tests from a short description; a developer decides how state and data flow, reviews every change and fixes what the AI got wrong. The time saved goes into accessibility, tests and performance, which are the first things cut on a tight budget.

Accessibility is part of every component. Menus, dialogs, tabs and forms follow the patterns in the ARIA Authoring Practices Guide, work with a keyboard and announce themselves to screen readers. We test with a keyboard and a screen reader before release, not only with a mouse.

Performance is measured on phones. React makes it easy to ship too much JavaScript, and Google’s Interaction to Next Paint metric, with a good threshold of 200 milliseconds on web.dev, measures exactly what that costs. We keep bundles small, load components only where they are needed and check field data after launch.

Ownership matters as much as the code. Every React app we build lives in a repository in your name, with a short README that explains how to run it, where data comes from and how to deploy a change. React components are named and organized so another React developer can find their way around in an afternoon, and the handover includes a walkthrough of the parts most likely to change.

The smallest React that does the job.

How we use AI here

How AI-assisted React development works here.

  • Components in hours

    Forms, tables, filters and charts drafted by AI tools from a short spec, then reviewed and adjusted.

  • Tests that get written

    Component and interaction tests drafted alongside the code, so they exist from day one.

  • Takeovers made safer

    An inherited React app mapped and explained before we change it.

What we don’t do: accept AI-written code without reading it, skip accessibility because a component “looks right”, or send your data and keys to AI tools. A developer owns every change that ships.

What’s included

What React development includes.

  • Scope and sizing

    Whether you need a component, a framework app or something simpler, decided in writing.

  • Interface design pass

    Screens sketched and agreed, or built from your designs.

  • Components in TypeScript

    AI-assisted, reviewed, typed and organized so another developer can work on them.

  • Data and API layer

    Clear data fetching and state, with an API behind it where needed.

  • Accessibility checks

    Keyboard, screen reader and contrast checks on every interactive part.

  • Performance checks

    Bundle size and interaction responsiveness measured on phones.

  • Tests

    Tests for the flows that matter most, run on every change.

  • Handover

    Documentation, repository access in your name and a walkthrough.

Four kinds of React development: frontends and dashboards, admin tools, embedded components, WordPress blocks
Four kinds of React work.

How we run it

Four steps, in this order.

The smallest build that does the job, then tested properly. Typical timing: the scope within 2 workdays, the build in 2 to 4 weeks depending on size, then testing, launch and handover in the final week.

  1. Step 1

    Size it

    Component, embedded widget or full app: agreed before anything is built.

  2. Step 2

    Prototype

    A working version of the key screen for your feedback.

  3. Step 3

    Build and test

    Full build with tests, accessibility and performance checks.

  4. Step 4

    Release and hand over

    Released with your approval, monitored, documented.

FAQ

Straight answers.

Can’t find yours? Ask on WhatsApp or by email and we’ll answer it.

Do we need a full React app?

Often not. A single interactive piece can be a small React component embedded in your current site. We size the build to the job before quoting.

Do you build React apps from scratch?

Usually on a framework, as React’s own docs recommend: Next.js for full apps and sites. A small embedded component doesn’t need one.

Can you build custom WordPress blocks in React?

Yes. The WordPress block editor is built with React, and custom blocks are React components registered with WordPress.

Can you add React to a Webflow site?

Yes. Webflow code components are React components designers can use on the canvas, and we build them with props and slots your team can edit.

How do you use AI in React development?

AI tools draft components and tests from a spec. A developer designs the state and data flow, reviews every change and owns what ships.

Will a React component slow our site down?

Not if it loads only where it is used and stays small. We measure bundle size and interaction responsiveness on phones before release.

Can you take over our existing React app?

Yes. We start by mapping the code, dependencies and build setup, then fix the riskiest problems before adding features.

Is it accessible?

Interactive parts follow the W3C’s ARIA patterns and are tested with a keyboard and a screen reader before release.
