Designing Cooperate's offline-first experience

Construction crews rarely enjoy stable Wi-Fi. That informed every layer of Cooperate's platform: from the marketing site to the workforce marketplace and messaging surfaces that must stay available even with patchy mobile coverage.

Field teams rely on offline-ready data to keep schedules moving.

Goals for a resilient PWA

• Instant launch. Critical dashboards cache via service worker precaching so crew leads see availability data within seconds.
• Background sync. Outgoing messages, agreement approvals, and audit pings queue locally and replay automatically when connectivity returns.
• Secure session refresh. We lean on @supabase/ssr and hardened cookies so expiring sessions can be renewed without exposing tokens to client storage.

The caching blueprint

We separate caches by sensitivity:

1. Public marketing assets use immutable caching with versioned paths, enabling snappy landing pages even in airplane mode.
2. Tenant-scoped APIs avoid caching and always revalidate through server actions to respect RLS policies.
3. Background assets such as locale dictionaries and UI sprites use stale-while-revalidate to balance freshness and reach.

This approach lets Cooperate serve rich marketing content instantly while protecting private workforce, messaging, and agreement data.

What’s next on the PWA roadmap

• Install prompts tuned per locale so Norwegian, Polish, and English speakers receive system-friendly copy.
• Offline-ready notifications that prefetch conversation context.
• Granular sync indicators in the messaging UI for absolute clarity when delivery is pending.

We’re eager to see how field teams use these features. Send feedback to product@cooperate.no.
