FAQ
Didn’t find what you were looking for? Drop us a line at info@toimi.pro.
What are the technical requirements for PWAs?
PWAs require HTTPS, service workers for offline functionality, web app manifest for installability, responsive design, and progressive enhancement architecture.
Do you build PWAs for Philadelphia businesses?
Yes. We develop progressive web apps for Philadelphia companies needing app-like experiences without platform-specific development.
How do service workers enable offline functionality?
Service workers intercept network requests, cache assets and data locally, and serve cached content when offline or on slow connections.
How long does PWA development take?
Typically 8-14 weeks depending on feature complexity, API integrations, offline requirements, and existing infrastructure.
What web APIs can PWAs access?
Geolocation, camera, microphone, push notifications, background sync, payment request, storage, sensors, and most device capabilities modern browsers expose.
How do PWAs compare to native apps technically?
PWAs use web technologies, run in browsers, update instantly, and work cross-platform. Native apps access more device features but require platform-specific development.
What caching strategies do you implement?
Cache-first for static assets, network-first for dynamic content, stale-while-revalidate for balanced approaches, and custom strategies based on requirements.
Can PWAs work on iOS devices?
Yes. iOS supports PWAs with some limitations compared to Android, but core functionality including installation and offline capability works.
How do you handle background sync in PWAs?
Through background sync API, queuing failed requests, syncing when connectivity returns, and maintaining data consistency across sessions.
What long-term value does PWA development provide?
PWAs eliminate platform dependencies, reduce development costs, enable instant updates, provide universal access, and leverage progressive enhancement.
