Adapt

Motivation

This initially started as a continuation of FerrisChat, which (after a rewrite) evolved into a completely independent codebase and project.

FerrisChat was the first OSS project I contributed to consistently, so it made sense to continue building on that foundation.

Infrastructure

Rust Backend

• REST services (public API, content delivery network, and media proxy) written using axum
• CDN tags images with metadata processed using RIL (see “Projects/RIL”)
• WebSocket written using tokio-tungstenite and communicates using RabbitMQ message broker
• Voice server based on WebRTC protocol

Data Storage

• Durable models such user accounts stored using PostgreSQL, cached using Redis
• Ephemeral models such as message acknowledgements and user mentions are stored on Redis

Front-end

• Web-based client served at https://app.adapt.chat, written using Solid.js, Tailwind CSS, and Tauri
• Landing and onboarding webpage served at https://adapt.chat, written using Astro and Tailwind CSS
