## Build from source

## Usage

Create a new NoSleep object and then enable or disable it when needed as follows:

``` javascript
var noSleep = new NoSleep();

function enableNoSleep() {
  noSleep.enable();
  document.removeEventListener('touchstart', enableNoSleep, false);
}

// Enable wake lock.
// (must be wrapped in a user input event handler e.g. a mouse or touch handler)
document.addEventListener('touchstart', enableNoSleep, false);

// ...

// Disable wake lock at some point in the future.
// (does not need to be wrapped in any user input event handler)
noSleep.disable();
```
