Server Command

Overview

The routa server command starts the Routa HTTP backend server, providing REST APIs and WebSocket endpoints for the web UI and external integrations. The server implements the same APIs as the Next.js backend but is built with Rust and Axum for better performance and standalone deployment.

Usage

routa server [OPTIONS]

Options:

--host <HOST> - Host to bind to (default: 127.0.0.1)
--port <PORT> - Port to listen on (default: 3210)
--static-dir <PATH> - Path to static frontend directory (optional)

Starting the Server

Basic Usage

Start the server with default settings:

routa server

Output:

Starting Routa server on 127.0.0.1:3210...
Routa server listening on http://127.0.0.1:3210

Custom Host and Port

Bind to a specific host and port:

routa server --host 0.0.0.0 --port 8080

Output:

Starting Routa server on 0.0.0.0:8080...
Routa server listening on http://0.0.0.0:8080

With Static Frontend

Serve static frontend files (Next.js export):

routa server --port 3210 --static-dir ./dist

The server will serve:

API routes at /api/*
Static files from the --static-dir directory
Frontend routes for the web UI

Custom Database

Use a specific database file:

routa --db /path/to/project.db server --port 3210

Server Endpoints

RUST_LOG=debug routa server

# Info for server, debug for core
RUST_LOG=routa_server=info,routa_core=debug routa server

# Trace level (very verbose)
RUST_LOG=trace routa server

Production Deployment

Systemd Service

Create a systemd service file:

# /etc/systemd/system/routa.service
[Unit]
Description=Routa Multi-Agent Coordination Server
After=network.target

[Service]
Type=simple
User=routa
WorkingDirectory=/opt/routa
Environment="ROUTA_DB_PATH=/var/lib/routa/routa.db"
Environment="RUST_LOG=info"
ExecStart=/usr/local/bin/routa server --host 0.0.0.0 --port 3210 --static-dir /opt/routa/dist
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable routa
sudo systemctl start routa
sudo systemctl status routa

Docker Deployment

Run the server in a Docker container:

docker run -d \
  --name routa-server \
  -p 3210:3210 \
  -v /data/routa:/data \
  -e ROUTA_DB_PATH=/data/routa.db \
  -e RUST_LOG=info \
  routa/routa:latest \
  server --host 0.0.0.0 --port 3210

With Docker Compose:

version: '3.8'

services:
  routa:
    image: routa/routa:latest
    command: server --host 0.0.0.0 --port 3210
    ports:
      - "3210:3210"
    volumes:
      - routa_data:/data
    environment:
      ROUTA_DB_PATH: /data/routa.db
      RUST_LOG: info
    restart: unless-stopped

volumes:
  routa_data:

Start with:

docker-compose up -d

Reverse Proxy (Nginx)

Configure Nginx as a reverse proxy:

upstream routa_backend {
    server 127.0.0.1:3210;
}

server {
    listen 80;
    server_name routa.example.com;

    # Redirect HTTP to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name routa.example.com;

    ssl_certificate /etc/letsencrypt/live/routa.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/routa.example.com/privkey.pem;

    # Proxy to Routa server
    location / {
        proxy_pass http://routa_backend;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket support
        proxy_read_timeout 86400;
    }

    # SSE support for MCP
    location /api/mcp {
        proxy_pass http://routa_backend;
        proxy_set_header Connection '';
        proxy_http_version 1.1;
        chunked_transfer_encoding off;
        proxy_buffering off;
        proxy_cache off;
    }
}

Health Checks

Check server health:

curl http://localhost:3210/api/health

Response:

{
  "status": "ok",
  "version": "0.1.0",
  "database": "connected",
  "timestamp": "2026-03-03T12:00:00Z"
}

Monitoring

Server Logs

View server logs:

# If running as systemd service
sudo journalctl -u routa -f

# If running in Docker
docker logs -f routa-server

# If running directly
routa server 2>&1 | tee routa.log

API Metrics

Monitor API usage:

# Request count by endpoint
grep '"method":' routa.log | \
  jq -r '.method' | \
  sort | uniq -c | sort -rn

# Response times
grep '"duration_ms":' routa.log | \
  jq -r '.duration_ms' | \
  awk '{sum+=$1; count+=1} END {print "Avg:", sum/count, "ms"}'

Testing the Server

JSON-RPC Request

Test the RPC endpoint:

curl -X POST http://localhost:3210/api/rpc \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "agents.list",
    "params": {"workspaceId": "default"}
  }'

WebSocket Connection

Test WebSocket with wscat:

npm install -g wscat

# Connect to event stream
wscat -c ws://localhost:3210/api/events

# Connect to ACP chat
wscat -c ws://localhost:3210/api/acp/chat

Load Testing

Perform load testing with wrk:

# Install wrk
sudo apt-get install wrk  # Ubuntu/Debian
brew install wrk          # macOS

# Run load test
wrk -t4 -c100 -d30s --latency http://localhost:3210/api/health

Stopping the Server

Press Ctrl+C to gracefully stop the server:

^C
Shutting down...

The server will:

Close all active connections
Flush database writes
Clean up resources
Exit cleanly

Comparison with Next.js Server

The Rust server provides the same APIs as the Next.js backend:

Feature	Rust Server	Next.js Server
REST APIs	✅ Identical	✅ Reference
JSON-RPC	✅ Same protocol	✅ Same protocol
WebSocket	✅ Native support	✅ Via ws library
MCP (SSE)	✅ Native support	✅ Via SSE
ACP	✅ Native support	✅ Via ACP SDK
A2A	✅ Native support	✅ Via A2A SDK
Database	SQLite only	SQLite + Postgres
Static files	Optional	Next.js routing
Performance	High (compiled)	Good (JIT)
Memory	Low (~50MB)	Higher (~200MB)
Deployment	Standalone binary	Node.js runtime

Troubleshooting

Port Already in Use

If port 3210 is busy:

# Find process using the port
lsof -i :3210

# Use a different port
routa server --port 8080

Database Locked

If you see “database is locked”:

# Ensure no other Routa instances are running
pkill routa

# Or use a different database
routa --db another.db server

Permission Denied

If binding to port fails:

# Use a port > 1024 (non-privileged)
routa server --port 8080

# Or run with sudo (not recommended)
sudo routa server --port 80
