Examples

These example apps show postal in the context of real browser features. Each one demonstrates a specific combination of postal patterns — check the individual pages for architecture breakdowns and live demos.

Notification Dashboard Interactive pub/sub demo. Shows getChannel, publish, wildcard subscriptions, live subscribe/unsubscribe toggling, and wiretaps — no transports, no workers, just the core API.

Gif Stitch Webcam-to-animated-GIF recorder. Shows transport bridging, request/handle RPC, pub/sub progress, and zero-copy transferables — all in one app.

Tab Sync Dashboard Cross-tab state sync using postal's BroadcastChannel transport. Shows the localStorage + BroadcastChannel production pattern, echo prevention in postal core, and wiretap observability.
