Mosh

Mosh is a desktop-first decentralized messenger built with Tauri v2, React, TypeScript, Rust, the Moss shared runtime, and an OpenMLS-oriented private messaging architecture.

Current Slice

The current tracer bullet focuses on a private 1:1 desktop direct-message flow:

• onboarding and invite URI shape
• manual fingerprint confirmation
• OpenMLS message-layer privacy model
• Moss tracker-based discovery model
• diagnostics for native/runtime boundaries

Friend Test Flow

1. Install and open Mosh on both desktops.
2. One device clicks Create invite; Mosh copies a mosh://invite?...#fp=... URI.
3. Send that URI to the friend through any existing channel.
4. The friend pastes the URI into Invite URI and confirms the fingerprint out of band.
5. Both devices can send messages; receive refresh runs automatically over Moss default/public tracker discovery.

Users should not enter peer hosts, ports, or local listen ports in the primary flow.

Commands

npm install
npm run build

Local Build Cache

• Cargo uses src-tauri/target for reusable Rust build artifacts.
• TypeScript writes incremental build metadata into node_modules/.cache.
• The first Rust test/build can still take several minutes while Tauri dependencies compile.
