REST API backend for Rustification, a chat application. Built with Axum, SQLx, and PostgreSQL.

Tech stack

Layer	Technology
HTTP framework	Axum 0.8
Database	PostgreSQL 17 via SQLx 0.9
Auth	JWT (jsonwebtoken) + Argon2 password hashing
Runtime	Tokio
Migrations	SQLx built-in

Features

• Auth — register, login, logout, JWT refresh via bearer tokens
• Workspaces — create and manage workspaces with owner/admin/member roles and invite tokens
• Conversations — DMs, group chats, and channels; public or private
• Messages — send, edit, soft-delete; per-conversation history
• Attachments — link files to messages (URL-based)
• Reactions — emoji reactions per message
• Soft deletes on users, workspaces, conversations, and messages (excluded from all list/get responses)

Prerequisites

• Rust (edition 2024)
• PostgreSQL 17, or Docker + Docker Compose

Getting started

1. Configure environment

cp .env.example .env
# Edit .env — set POSTGRES_*, DATABASE_URL, API_URL, API_PORT, JWT_SECRET

2a. Run with Docker Compose (recommended)

Starts PostgreSQL and the server together:

docker compose up --build

The server will be available at http://localhost:3000.

2b. Run locally

Requires a running PostgreSQL instance matching your DATABASE_URL.

# Install sqlx-cli if needed
cargo install sqlx-cli --no-default-features --features rustls,postgres

# Run migrations
sqlx migrate run

# Start the server
cargo run
