    Single-page apps

    A single-page app (SPA) offers seamless transitions between pages, reduces load times, and provides an abundance of micro-interactions — small, intuitive bits of design and animation that help guide, engage, and delight your user. Because of their very nature, SPAs are resistant to user-facing failure, so no more 404 errors. Your user continues along on your website unhampered. If you’re considering adding SPAs to your high-level site architecture, Caktus experts can help guide you to the software frameworks that make the most sense for your business.
