Introducing cpp.js.org: Revolutionizing C++ and JavaScript Bridging

Küçük describes cpp.js.org as a toolset for C++ developers who want to bring existing skills and code to web and mobile. The goal is to write application logic in regular C++ and build the interface with React Native, while supporting other JavaScript environments too.

The project setup starts with `npm create cppjs@latest`; the first installation may take five to ten minutes. Templates cover web, mobile, backend, cloud, and libraries. In the Hello World example, JavaScript imports a C++ header, waits for `initCPPJS`, then calls C++ functions and creates objects.

Küçük outlines tools that generate interfaces between C++ and JavaScript, including CPPJS, SWBind, Emscripten Plus, and JSI++. Web builds use Emscripten, while mobile builds use the Android NDK or Xcode to produce native binaries for ARM64 and x86-64 simulators. Bundler plugins connect headers to projects; Küçük says they cover about 90% of available bundlers.

Küçük says 15 libraries are already available to import, including SQLite. He demonstrates a hiking app that could use GDAL to query large digital elevation model files offline, and describes using ZIP through an app config and import. To port another library, developers provide its source repository and version in build and config files, then run `cppjs build`.

Küçük invites library experts to contribute and shares contact details for cpp.js.org and a new library email address. He says C++ can outperform equivalent JavaScript code, while the bridge matches Emscripten performance; primitive values are copied and objects are shared through pointers. Functions that return pointers and object cleanup may need manual handling.
