Package Exports

guard

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (guard) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

guard

Trivial guard: triggers callback when internal counter reaches 0.

API

Create guard passing callback function. Call on() and off() to increase and decrease internal counter.

g = guard(function() {
  console.log('Done...')
});
g.on();
g.on();
g.off();
g.off(); // prints 'Done...'

You can initialize the counter when creating a new guard.

g = guard(function() {
  console.log('Done...')
}, 2);
g.on();
// call off 3 times
g.off();
g.off();
g.off(); // prints 'Done...'

In addition to done callback you can setup callbacks when counter reaches a certain value during on or off

g = guard()
  .onCallback(100, function() {
    // called when internal counter is 100 after increment
  })
  .offCallback(10, function() {
    // called when internal counter is 10 after decrement
  });
