Make all calls to a function queued and asynchronously guarded
Install the module with: npm install asynccallguard
var AsyncCallGuard = require('asynccallguard');
var w = 100;
var f = function(){console.log(Array.prototype.slice.call(arguments));};
var f2 = AsyncCallGuard(f, function MyGuard(fcall){
//
// ... Some complex logic here...
//
w *= 2;
console.log('MyGuard was called, waiting for '+w+'ms before running f');
setTimeout(fcall, w);
});
// Make multiple calls
f2();
f2(1,2);
f2(3,4);
f2(5,6,7);
// Produce:
// MyGuard was called, waiting for 200ms before running f
// []
// MyGuard was called, waiting for 400ms before running f
// [ 1, 2 ]
// MyGuard was called, waiting for 800ms before running f
// [ 3, 4 ]
// MyGuard was called, waiting for 1600ms before running f
// [ 5, 6, 7 ]v1.0.0 - Initial commit (13 apr. 2012)
