CppCon 2015

Session presents Open Service Platform (OSP) - an application server engine inspired by OSGi, consisting of C++ and JavaScript runtime environments; OSP is based on the POCO C++ Libraries, with embedded Google V8 JavaScript engine.

A brief overview of the application server and underlying technologies will be given, followed by dissection of the most interesting implementation details - C++-to-JavaScript bridging mechanism and WebSocket-based messaging mechanism for transparent intra- and inter-process scalable communications. The language bridging mechanism exposes the C++ classes to JavaScript code without a need for manually written glue code or separate IDL constructs for interfaces. The messaging mechanism provides a unified, event-based interface for the in-process entities as well as those reachable over the network - be it TCP/HTTP server or a web browser.

Key design aspects, advantages, as well as trade-offs will be examined; a live example demonstrating key technologies in action will be presented.
