Examples

SpawnDev.SpawnJS Mapping Note: The JavaScript examples below show the standard Web API usage. In SpawnDev.SpawnJS, the same API is available with C# conventions:

• Properties and methods use PascalCase (e.g., readyState becomes ReadyState)
• Events use ActionEvent with +=/-= (e.g., addEventListener("click", fn) becomes OnClick += handler)
• Async methods return Task<T> instead of Promise<T>
• Objects should be disposed with using statements
• Access via JS.Get<WakeLock>(...) or constructor new WakeLock(...)

try {
  const wakeLock = await navigator.wakeLock.request("screen");
} catch (err) {
  // the wake lock request fails - usually system related, such being low on battery
  console.log(`${err.name}, ${err.message}`);
}
