JavaScript development
Interactivity added deliberately, layered over markup that already works — so a failed script never leaves a blank page.
Language
Chosen per project
Maintainable handover
A great deal of what is built in frameworks does not need one. A search overlay, an accordion, a carousel, form validation — these are all modest amounts of well-structured JavaScript, and shipping them without a framework keeps the page fast and the code easy to follow.
The principle that matters more than the tooling is progressive enhancement: the page should be usable before the script runs, and better after. That way a network failure or a blocked file degrades the experience instead of destroying it.
What we build with JavaScript
Interactive components on otherwise static sites
Form validation with accessible error handling
Search, filtering and sorting without a page reload
Progressive enhancement over server-rendered pages
Where it fits — and where it does not
Good fit when
Interactivity that does not justify a framework
Performance budgets that rule out a large runtime
Features that must degrade gracefully
Long-lived code with no framework upgrade treadmill
Consider something else when
Large applications with heavy shared state need a framework
Teams already standardised on React or Angular
Anything needing a mature component ecosystem
When plain JavaScript is the better answer
The honest test is how much shared state the interface has. Very little and a framework is overhead; a great deal and hand-rolling it is a slow reinvention of one.
Plain JavaScript fits
Independent components with little shared state
Content sites with pockets of interactivity
Strict performance budgets
Features that must degrade gracefully
Code expected to last without upgrades
Reach for a framework
State shared across many components
Dozens of screens with common patterns
A team already fluent in one
A component ecosystem worth inheriting
Server rendering and routing needed together
How we work with JavaScript
Progressive enhancement
The page works first; the script improves it. A failed load costs a feature, not the page.
Module boundaries
One responsibility per file with a clear init function, so a broken feature cannot take the page down.
Accessible interactions
Keyboard support, managed focus and correct ARIA state on every custom control.
Event discipline
Delegated listeners, passive scroll handlers and work moved off the main thread where it matters.
Our typical JavaScript setup
| Concern | What we use |
|---|---|
| Language level | ES6+, written to run natively in current browsers |
| Modules | ES modules where served over http; classic scripts where file:// support matters |
| Patterns | Event delegation, IntersectionObserver, matchMedia |
| Accessibility | Focus management and ARIA state on every custom control |
| Testing | Unit tests on logic, plus real interaction testing in browsers |
Frequently asked questions
For the right problem, absolutely. Browsers now provide natively much of what frameworks were built to paper over. The deciding factor is how much shared state the interface really has — not what is fashionable.
The page renders and works from the server-delivered markup; JavaScript then improves it. A visitor on a failed script still sees content and can navigate, instead of a blank screen.
For anything beyond a few hundred lines, usually yes — the type checking pays for itself. For a handful of small independent components, plain JavaScript with good structure is perfectly maintainable.
Services built with JavaScript
Website Development
A website is usually the first thing a prospective customer sees. It should load quickly, say something useful and be findable.
Web Application Development
Applications that run in the browser, handle real workloads and hold up when several departments depend on them at once.
UI/UX Design
Interfaces designed around what people are trying to accomplish, then tested with them before development starts.
