Sri's Universal Realtime System (URSYS)

URSYS is a Javascript development framework for webapps that communicate with each other through a server. Background

URSYS originated in learning science research into embodied learning from 2013 to date. The requirements were LAN-based operation, realtime graphics, simulation, video, and motion tracking served from a single laptop to multiple tablet and Chromebook-type devices in a guided classroom environment.

This repository is a modular rebuild of support features I've developed for these project. The development goal is to create many "building blocks" that hide the difficult parts of asynchronous lifecycle-driven programming in a distributed network environment under an open license compatible with contract work for the NSF grants I am working on. The usability goal is to make a NodeJS-based framework that can be used productively by intermediate-level developers who are just getting into asynchronous realtime graphics simulation programming. I'd like this to be as "plug and go" as possible. For a more detailed list of this project's goals, see Development Priorities in the Wiki.

Features

• Designed to use Visual Studio Code features from integrated terminal.
• Works on MacOS/Linux systems with a minimum of 4GB memory free.
• Monorepo structure implemented with npm workspaces.
• Modular separation between core, addon, and app directories for easy extensibility.
• Designed for simple copy/paste folder operation with automatic configuration whereever possible.
• Command line ur auto-discovers and spawns addons processes.
• Tested with nginx proxy forwarding for both http and websocket connections.
• Verbose prompting and guardrails to help users understand what's going on.
• Favors straightforward fluent code patterns and formatting so source code is easy to scan.

Under Development

• see Closed Pull Requests for an idea of what's new.
• pending: import URSYS as a dependency into existing projects
• pending: other feature porting candidates
