RegisterConsoleCallback

Since: IVPrismaUI2

virtual void RegisterConsoleCallback(
    PrismaView view,
    ConsoleMessageCallback callback
) noexcept = 0;

Receives every console.log/warn/error/debug/info call from the view's JS context.

Parameters​

  • view - Target view handle.
  • callback - Receives the view, the ConsoleMessageLevel, and the message text. Pass nullptr to unregister.

Threading​

Fires on the main game thread.

Best practice​

Register this during development for every view - without it, JS errors are otherwise completely silent, which makes a broken page look identical to one that just hasn't loaded yet.

Example​

api->RegisterConsoleCallback(view,
    [](PrismaView, PRISMA_UI_API::ConsoleMessageLevel lvl, const char* msg) {
        using L = PRISMA_UI_API::ConsoleMessageLevel;
        const char* tag = lvl == L::Error   ? "[JS ERR] "
                        : lvl == L::Warning ? "[JS WARN]"
                                            : "[JS LOG] ";
        logger::info("{} {}", tag, msg);
    });
