Simbol Demo

Get up and running with Simbol by building on top of this demo. It provides both the client, thay uses the Simbol library, and the minimal server, based on simbol-server. Both are used using Docker, making deploying your site easy and fast, with minimal configuration.

Getting Started


There's a minimal website in /client with an index.html and main.css. The JavaScript is in /src, in index.js. There's an example Simbol usage, that loads a scene from assets/demoscene.glb. You can check out the code in index.js.

First you need to install dependencies (which includes simbol). Do this from the /client directory:

cd client npm install

If you make JavaScript changes, run npm run js to compile them using Rollup.


This demo provides an example of how to use simbol-server in /server. Simbol requires a server for two reasons:

  • It needs an HTTP server to serve the Web Content
  • It needs a WebSocket server to take care of signaling for the multiuser experience provided in your site

It add two routes for /assets and /build and runs the HTTP and WebSockets server that simbol-server provides. You can modify and add routes as you need.

To run the server, make sure you are in the /server directory:

cd server

and run it with Cargo:

cargo run

Now your website is accessible in http://localhost:3000 and the WebSocket server is in http://localhost:8000


Once you have finished your 3D website and configured your server's routes, you can deploy your site in a server or VPS using docker. You can also do this locally, and it takes care of compiling both the client and the server and intalling all necessary dependencies.

It will also install and configure CoTurn. This is a TURN server that provides backup for the multiuser experience in Simbol.

To build the Docker container, run the following command changing the build arguments for your values:

docker build --build-arg --build-arg --build-arg COTURN_USER=test --build-arg COTURN_PASSWORD=secretpassword -t simbol-demo .

And then run the container. It opens the port for simbol-server and for CoTurn.

docker run -p 3000:3000 -p 8000:8000 -p 3478:3478 -p 5349:5349 -p 3479:3479 -p 5350:5350 -d --name=simbol-demo simbol-demo

Adding the CoTurn server to Simbol

Running your Docker container will run the CoTurn server on port 3478. You can then tell Simbol that information so it can depend on CoTurn when creating the multiuser experience. You do this in the configuration object:

	virtualPersona: {
		multiVP: {
			socketURL: 'wss://',
			socketPort: '80',
			iceServers: [
				{urls: ''},
					urls: '',
					username: 'test',
					credential: 'secretpassword'
					urls: '',
					username: 'test',
					credential: 'secretpassword'

Remember to change for your domain and setting the username and password.

There's a modifiable example in client/src/index.js.
