What is Litegraph.js?
LiteGraph.js is a JavaScript library for creating and editing node-based graphs, similar to Unreal Engine's Blueprints system. It provides a visual programming environment where developers can design, test, and execute graphs in the browser or on a server. The library solves the problem of building complex interactive systems, data pipelines, and visual scripting tools without heavy dependencies.
Web developers and creative coders building visual programming interfaces, dataflow applications, game logic editors, or interactive multimedia tools in the browser.
Developers choose LiteGraph.js for its lightweight, dependency-free design, built-in editor, and flexibility to run graphs both client-side and server-side. Its ease of integration and support for custom node creation make it ideal for embedding visual scripting into existing projects.
