GDI.js - Javascript runtime for windows

API Documentation: https://gdi.sh/docs v8 Documentation: https://v8.dev/docs JS Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript

About

GDI.js is an experimental javascript runtime that implements win32 api calls into v8 interface. Started as a personal digital assistant project at 2009. Switched from Mozilla's spidermonkey to Google's V8 engine at 2014. It's gained attraction in corporate environment and eventually became a drop-in replacement of node.js with extra arms.

Key differences

• Multithreading: While other runtimes driven by async event loops to maximize I/O throughput, GDI.js uses standard windows message loop with multithreaded operations for sake of simplicity.
• Native desktop: GDI.js is just a native desktop application. It can directly access to serial ports, activex objects, desktop, network, gpu, external DLL's without requiring any extra module.
• Smaller payload: Bare minimum stack, GDI.exe and engine.dll is just 13.4mb while implementing modern ECMA-262 standard (for comparison, node.exe is around 90mb today)

Usage scenerios

• Rapid JS prototyping hence the fast bootup
• Build monitoring applications for your arduino projects
• Create data sources for your desktop widgets
• Connect to web services, process and manipulate data, send it back

Building instructions

• Fork the engine repository and build the engine.dll by using visual studio 2015. Main branch pre-configured for dll deployment.
• Fork the boot repository and create the engine.js by running merge.bat
• Drop the both files into project sources and run res.bat resources.rc to generate resource file
• Generate the executable by compiling gdi.dpk
