Web & SaaS
Single-Page Apps, Done Right
A single-page application loads once and updates instantly, which feels like a native app. We build them with care for the trade-offs that come with that model.
Overview
Single-Page Applications
A single-page application, or SPA, loads a shell once and then updates content dynamically in the browser, instead of requesting a new page for each click. The result is fast, fluid interaction well suited to dashboards, editors and tools used for long sessions. The trade-offs are initial load size, search visibility and careful handling of browser history and state.
We build SPAs with frameworks such as React, Angular or Vue, and we make deliberate choices about routing, code splitting and caching. Where public pages need to be indexed, we add server-side rendering or pre-rendering. Not every project should be an SPA, and we say so when a conventional multi-page site would serve you better.
Context
Problems we solve
- 01
Heavy first load
Shipping the whole application up front delays the first screen, especially on slow connections.
- 02
Search visibility
Content rendered only in the browser can be harder for search engines to read if not handled carefully.
- 03
State and navigation bugs
Back buttons, deep links and refreshes behave unexpectedly if routing and state are poorly designed.
- 04
Memory and long sessions
Apps left open for hours can slow down if listeners and data are not cleaned up.
Capabilities
What we deliver
- 01
Framework selection
A reasoned choice among React, Angular and Vue based on your project and team.
- 02
Routing and deep links
Reliable navigation, shareable URLs and correct behavior of the back button.
- 03
Code splitting and lazy loading
Loading only what each screen needs to keep initial loads lean.
- 04
Server-side rendering options
Pre-rendering or SSR for public content that must be indexed and load quickly.
- 05
State management
Predictable handling of application data, caching and synchronization with APIs.
- 06
Testing and monitoring
Component and end-to-end tests plus error tracking in production.

Approach
How we deliver
- 1
Discover
We learn your goals, users, constraints and existing systems before proposing anything.
- 2
Plan
Scope, priorities, architecture and milestones are agreed so everyone knows what ships when.
- 3
Design
User flows, interfaces and technical design are shaped and reviewed with you early.
- 4
Build
Work is delivered in short iterations with regular demos, so progress is always visible.
- 5
Test
Functional, integration and performance checks run throughout, not only at the end.
- 6
Launch & support
We deploy, monitor and keep improving the product after it goes live.
FAQs
Common questions
Have a question that is not covered here? Get in touch.
Is an SPA right for every website?
No. Content-heavy marketing sites often work better with server-rendered or static pages. SPAs shine where interaction is rich and sessions are long, such as dashboards and tools.
Will an SPA hurt our search visibility?
It can if public content is rendered only in the browser. For pages that need to be found, we use server-side rendering or pre-rendering so search engines receive complete content.
Can an SPA work offline?
With a service worker and local storage, parts of it can. That moves the project toward a progressive web app, which we can scope separately.
