    Drawsocket

    drawsocket is an node.js based server/client platform for generating synchronized, browser-based displays across an array of networked devices.

    Developed at the Hochschule für Musik und Theater Hamburg in 2019 for a series of large scale concerts in the St.Pauli-Elbtunnel as part of the Innovative Hochschule Stage_2.0 project, drawsocket was conceived as a system for distributed notation display over a local area network for use in music and spatial performance contexts.

    drawsocket provides a unified interface for controlling diverse media features of web-browsers (SVG, WebAudio, animation, etc.), which can be utilized in many ways--and additionally provides access to browser mouse and multi-touch gesture interaction data, which can be used for the creating of graphical user interfaces.

    For more information, please see the documentation website at drawsocket.github.io

    Installation

    drawsocket can be run either as a standalone server, or inside the Max media programming application.

    Max Package

    Requires Max version >= 8.1.0, and CNMAT's Odot library, and works well in the MaxScore notation framework.

    To install:

    1. Download the latest Max Package release from the drawsocket-max repository.
    2. Unzip the downloaded release folder.
    3. Place the drawsocket repository in the /Documents/Max 8/Packages folder.
    4. Restart Max.
    5. Make a new patcher and put a drawsocket object (abstraction) in the patcher, and go to the drawsocket help patch.
    6. When running the drawsocket server for the first time: click on the script npm install message to download the drawsocket module and dependency libraries (note that you will need to be connected to the internet for the download to work).
    7. Refer to the examples in the drawsocket help file, and in the Max Extras menu.
    8. See the Overview and API pages for more details.

    Pure Data

    Using the standalone UDP server, the odot Pd library you can send drawsocket compatible OSC bundles. See also the pd-communicate.pd patch in the drawsocket/example folder.

    Standalone UDP Server

    1. Install node.js if not already installed.
    2. Create a new directory and run: npm install drawsocket
    3. The drawsocket server can then be run by importing the module, initializing the server with drawsocket.init(), and starting with drawsocket.start().
    4. Initializing the server with the option enable_udp set to true starts the HTTP server with an additional UDP server which will listen for incoming drawsocket format OSC bundles and route them to the client browsers via WebSockets.
    5. See the Overview and API pages for more details.

    Minimal example:

    const drawsocket = require('drawsocket');
    
    drawsocket.init({
        node_path: './node_modules/',
        http_port: 3004,
        enable_udp: true,
        udp_listen_port: 9999,
        udp_send_port: 7777
    });
    
    drawsocket.start();
    
    

    Server Options

    const drawsocket = require('drawsocket');
    
    let params = {
        node_path: './node_modules/',               // path to node modules for client includes, default: `./..`
        userpath: null,                             // path for custom asset serving folder
        htmltemplate: '/lib/drawsocket-page.html',  // sets main drawsocket page, /lib/drawsocket-page.html is the default
        infopage: "/lib/drawsocket-info.html",      // sets landing page, /lib/drawsocket-info.html is the default
        http_port: 3002,                            // sets HTTP port, 3002 by default
        post: "default",                            // by default, console.log, otherwise settable to other print function (e.g. Max.post)
        outlet: "default",                          // by default, if UDP is enabled outlet will be set to use udp_server.send, else disabled
        enable_udp: false,                          // enable/disable UDP server, off by default
        udp_listen_port: 9999,                      // UDP listen port
        udp_send_port: 7777,                        // UDP send-to port
        udp_send_ip: "127.0.0.1"                    // UDP send-to IP address
    }
    
    drawsocket.init(params);
    drawsocket.start();
    

    Test Server

    A test HTTP/UDP server can be run from within the node_modules/drawsocket folder, by running node test.

    Optional arguments set UDP send-to IP and port, for example:

    node test --ip=192.168.0.1 --port=4444
    

    For testing drawsocket from the repository, use the -d flag to set the path to node_modules:

    node test --ip=192.168.0.1 --port=4444 -d
