A simple utility to check network status (online/offline) and listen for changes in the connection.

// index.js
export function useNetworkStatus(onChange) {
    const handleConnectionChange = () => {
      if (navigator.onLine) {
        onChange("online");
      } else {
        onChange("offline");
      }
    };
  
    // Add event listeners on mount
    const mount = () => {
      window.addEventListener("online", handleConnectionChange);
      window.addEventListener("offline", handleConnectionChange);
      handleConnectionChange();  // initial check
    };
  
    // Remove event listeners on unmount
    const unmount = () => {
      window.removeEventListener("online", handleConnectionChange);
      window.removeEventListener("offline", handleConnectionChange);
    };
  
    return { mount, unmount };
  }
