Modern, Header-Only Key-Value Store for C++.

PolyKV C++ provides a clean, standardized interface for persisting data in desktop applications. No external libraries required* (*uses standard STL).

One API, Everywhere. This library is part of the PolyKV ecosystem. Use the same consistent API across 12+ languages.

• ⚡️ Header-Only Easy integration. Just drop it in your include path and go. No complex linking required.

• 🖥 Cross-Platform Uses std::filesystem to handle paths gracefully across macOS, Windows, and Linux.

• 🛠 Standard API Follows the same setString / getMap naming convention as the high-level SDKs, simplifying porting.

#include "polykv.hpp"
#include <iostream>

int main() {
    polykv::PolyKV kv("MyApp");

    // 1. Save
    kv.set_string("mode", "dark");
    kv.set_number("width", 1920);

    // 2. Read
    std::cout << "Mode: " << kv.get_string("mode") << std::endl;

    // 3. Update
    kv.set_string("mode", "light");

    // 4. Delete
    kv.remove("width");

    // 5. Clear All
    kv.clear();
    
    return 0;
