Overview

The :feature:messaging module handles the core communication features of the app, including text messages, direct messages (DMs), and channel-based chat.

Key Components

1. MessageViewModel

Manages the state of the chat screen, including loading messages from the database, sending new messages, and handling message reactions.

2. QuickChat

A simplified chat interface for quickly sending and receiving messages without entering the full message screen.

3. HomoglyphCharacterStringTransformer

A security-focused utility that detects and transforms homoglyphs (visually similar characters from different scripts) to prevent phishing and impersonation attacks.

Features

• Channel Chat: Group communication on public or private channels.
• Direct Messaging: One-on-one encrypted communication between nodes.
• Message Reactions: Support for reacting to messages with emojis.
• Delivery Status: Indicators for "Sent", "Received", and "Read" (ACK/NACK).
