New Courier Inbox Launch

Courier has completely rebuilt Inbox to make in-app notifications faster, more flexible, and easier to integrate. This release introduces a new architecture, customizable UI, performance optimizations, and a simplified developer experience. All while maintaining compatibility with existing integrations.

What’s New

1. UI Flexibility

   • Support for custom components: override, extend, or replace the UI entirely.

   • Options for pop-up or full-screen view.

   • Theming via CourierInboxTheme, eliminating the need for CSS overrides.

   • Dynamic layouts and support for custom notification data.

2. Performance Improvements

   • Single WebSocket per tab to reduce resource usage.

   • Lazy-loaded messages, fetched only when needed.

   • Real-time sync across views, tabs, and channels.

3. Simplified Integration

   • Installation is now a breeze: one line of HTML and a few lines of JS or React code.

   • Introduction of the new useCourier React hook for direct inbox state and events.

   • Consolidated into a single package: @trycourier/courier-react
