it's unlimited within the session - - -## Server Architecture (Collaborative Mode) - -Moebius-web supports a collaborative server mode for real-time multi-user ANSI/ASCII art editing. -The collaboration engine is implemented in `server.js` (entry point) and `src/ansiedit.js` (session/canvas management). - -### Key Points: -- **Entry Point:** `server.js` - Starts an Express server, sets up session middleware, and configures WebSocket endpoints for both direct and proxied connections (`/ and `/server`). -- **Collaboration Engine:** `src/ansiedit.js` - Handles all real-time session management, canvas state, and user synchronization. -- **Persistence:** - Canvas and chat data are auto-saved to disk at configurable intervals, with timestamped backups for recovery. -- **SSL/HTTP Support:** - Can auto-detect and use SSL certificates for secure connections, or fall back to HTTP. -- **Session Customization:** - Supports custom session file names and save intervals. -- **Minimal Overhead:** - Designed for low resource usage—only manages collaborative drawing and session state. - -### How it Works: -1. **Start the server:** - ```sh - node server.js [port] [options] - ``` -2. **Clients connect via browser:** - - Directly, or through a reverse proxy (e.g., nginx). - - WebSocket endpoints handle all real-time drawing and chat messages. - -3. **Session persistence:** - - Canvas and chat are auto-saved to `{sessionName}.bin` and `{sessionName}.json`. +```sh +bun server [port] [options] +# or +node src/js/server/main.js +``` ---- +> [!TIP] +> The server starts on port `1337` by default. _so elite_ -## Server Command-Line Options +**Command-Line Options** | Option | Description | Default | |-----------------------|------------------------------------------------------------|---------------------| @@ -223,285 +268,77 @@ The collaboration engine is implemented in `server.js` (entry point) and `src/an | `--ssl-dir ` | SSL certificate directory | `/etc/ssl/private` | | `--save-interval ` | Auto-save interval in minutes | `30` (minutes) | | `--session-name `| Session file prefix (for state and chat backups) | `joint` | +| `--debug` | Enable verbose logging | `false` | | `--help` | Show help message and usage examples | -

During his early days there, he created the original “ansiedit,” laying the groundwork for this application. However, his focus soon shifted to developing a desktop-only editor, which evolved into Moebius. -### Dependencies +Around that time, xeR0 (then a member of [Impure!ASCii](https://16colo.rs/group/impure) and a devoted PabloDraw user) joined Blocktronics shortly after ansiedit’s release. xeR0 played the role of testing and debugging the app alongside Andy as he learned the dark arts of the blocks. -The server requires the following Node.js modules: +Fast forward a decade: xeR0 found himself sad he was still unable to use the new MoebiusXBIN fork to create text art on his iPad. With Andy’s blessing, xeR0 decided to revive the project—reimagining it from the ground up as a modern Progressive Web App. New features like optimized off-screen canvas', dirty pixel rendering, local storage sync, were added. But without Andy's core math this project would not be possible. -- `express` (Web framework) -- `express-session` (Session middleware) -- `express-ws` (WebSocket support) -- `fs`, `path` (built-in, for file and path management) +## License & Greetz -Install them with: + -```sh -npm install -# or -bun install -``` - -### Example: Systemd Service - -See the "process management" section above for a recommended systemd service file. +▒ mad love & respect to [Andy Herbert^67](http://github.com/andyherbert) - [Moebius](https://github.com/blocktronics/moebius) ░ [grmmxi^imp!](https://glyphdrawing.club/) - [MoebiusXBIN](https://github.com/hlotvonen/moebiusXBIN/) ░ [Curtis Wensley](https://github.com/cwensley) - [PabloDraw](https://github.com/cwensley/pablodraw) ░ [Skull Leader^ACiD](https://defacto2.net/p/skull-leader) - [ACiDDRAW](https://www.acid.org/apps/apps.html) ▒ --- -### Notes - -- The server serves the `/public` directory for static files. - Make sure your web server (nginx, etc.) points to this as the document root. -- If using SSL, ensure your cert and key files are named as expected or update the code/paths as needed. -- You can run the server as a background process using `systemd`, `forever`, or similar tools for reliability. -- If you want to use this as a local only editor, you can just put the "public" folder on a web-server and you're good to go. - -## process management - -### systemd (Recommended for Servers) -- Built-in service manager on most Linux distributions. -- Extremely lightweight, reliable, and secure (no extra processes or userland code to maintain). -- Create a unit file for the server: -```INI -[Unit] -Description=Moebius Web Node.js Server -After=network.target - -[Service] -ExecStart=/usr/bin/node /www/ansi/server.js -Restart=always -User=youruser -Environment=NODE_ENV=production -WorkingDirectory=/www/ansi/ -StandardOutput=syslog -StandardError=syslog - -[Install] -WantedBy=multi-user.target -``` -- Reload systemd and enable: -```sh -sudo systemctl daemon-reload -sudo systemctl enable --now moebius-web.service -``` -- Memory: Minimal—just your Node.js process. -- Monitoring: Use `journalctl` or your system's logging. - -### forever -- Simple Node.js CLI tool for restarting scripts. -- Install: npm install -g forever -- Run: forever start server.js -- Memory: Very low—almost just your script. -- Downsides: Less robust than systemd - - -The server runs on port `1337` by default. But you can override it via an argument to server.js. You will need to update the port the client uses in `public/js/network.js` on line #113. - -Now you need to setup a webserver to actually serve up the `/public` directory to the web. Here's an nginx example: - -Create or edit an nginx config: `/etc/nginx/sites-available/moebius` - -``` -server { - listen 80; - listen 443 ssl; - - default_type text/plain; - - root /www/ansi/public; - index index.php index.html index.htm; - - server_name ansi.0w.nz; - include snippets/ssl.conf; - - location ~ /.well-known { - allow all; - } - - location / { - try_files $uri $uri/; - } - location /server { - proxy_http_version 1.1; - proxy_set_header Upgrade $http_upgrade; - proxy_set_header Connection $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; - proxy_read_timeout 86400; - proxy_redirect off; - proxy_pass http://localhost:1337/; # use the correct port, and note the trailing slash - } -} -``` - -> Note that the webroot should contain the `/public` directory. -> proxy_pass should be the correct port you specified with a trailing slash. - -Make sure you define your SSL setting in `/etc/nginx/snippets/ssl.conf`.

Time to draw some **rad ANSi!** - -## Troubleshooting & Tips - -### Common Issues - -#### 1. Server Fails to Start / Port Already in Use -- **Symptom:** You see `EADDRINUSE` or "address already in use" errors. -- **Solution:** - - Make sure no other process is using the port (default: 1337). - - Change the server port with a command-line argument: - ```sh - node server.js 8080 - ``` - - Or stop the other process occupying the port. - -#### 2. SSL/HTTPS Doesn't Work -- **Symptom:** Server crashes or browser reports "insecure" or "cannot connect" with SSL enabled. -- **Solution:** - - Ensure your SSL cert (`letsencrypt-domain.pem`) and key (`letsencrypt-domain.key`) are present in the specified `--ssl-dir`. - - Double-check file permissions on the cert/key; they should be readable by the server process. - - If issues persist, try running without `--ssl` to confirm the server works, then debug SSL config. - -#### 3. Cannot Connect to Server from Browser -- **Symptom:** Web client shows "Unable to connect" or no collaboration features appear. -- **Solution:** - - Make sure the Node.js server is running and accessible on the configured port. - - Check that your reverse proxy (nginx) forwards WebSocket connections to `/server` with the correct port and trailing slash. - - Check firewall (ufw, iptables, etc.) for blocked ports. - - Review browser console and server logs for error details. - -#### 4. WebSocket Disconnects or Fails to Upgrade -- **Symptom:** Collaboration features drop out or never initialize. -- **Solution:** - - Confirm nginx config includes the correct WebSocket headers (`Upgrade`, `Connection`, etc.). - - Make sure proxy_pass URL ends with a trailing slash (`proxy_pass http://localhost:1337/;`). - - Try connecting directly to the Node.js server (bypassing nginx) for troubleshooting. - -#### 5. Session Not Saving / Data Loss -- **Symptom:** Drawings/chat are not persisted or backups missing. -- **Solution:** - - Ensure the server process has write permissions in its working directory. - - Check the value of `--save-interval` (defaults to 30 min); lower it for more frequent saves. - - Watch for errors in server logs related to disk I/O. - -#### 6. Permissions Errors (systemd, forever, etc.) -- **Symptom:** Server fails to start as a service or can't access files. -- **Solution:** - - Make sure the `User` in your systemd service file has read/write access to the project directory and SSL keys. - - Review logs with `journalctl -u moebius-web` for detailed error output. - -#### 7. Wrong Port on Client/Server -- **Symptom:** Client can’t connect, even though the server is running. -- **Solution:** - - The client code (see `public/js/network.js`, line ~113) must use the same port you start the server on. - - Update both if you change the port. - -### General Tips - -- **Auto-Restart:** - Always run the server with a process manager (systemd, forever) for automatic restarts on crash or reboot. -- **Frequent Saves:** - Lower the `--save-interval` value for high-collaboration sessions to avoid data loss. -- **SSL Best Practice:** - Always use SSL in production! Free certs: [let’s encrypt](https://letsencrypt.org/). - Automate renewals and always restart the server after cert updates. -- **Testing Locally:** - You can test the server locally with just `node server.js` and connect with `http://localhost:1337` (or your chosen port). -- **WebSocket Debugging:** - Use browser dev tools (Network tab) to inspect WebSocket connection details. -- **Session Backups:** - Periodic backups are written with timestamps. If you need to restore, simply rename the desired `.bin` and `.json` files as the main session. -- **Logs:** - Review server logs for all connection, error, and save interval events. With systemd, use `journalctl -u moebius-web`. -- **Firewall:** - Don’t forget to allow your chosen port through the firewall (`ufw allow 1337/tcp`, etc.). - -If you encounter unique issues, please open an issue on [GitHub](https://github.com/xero/moebius-web/issues) with error logs and platform details! - -# License - -Distributed under the MIT licence.
