Wrap and run promises in order (not at once) Like Q.all() but functions will run one after the other
Usage
Install
npm install --save seqprom
Create the seqprom object by passing in the function you need to loop through
var Seqprom = require('seqprom');
//we want to call this function sequentially
function wrapMe(arg1, arg2){
var deferred = Q.defer();
setTimeout(function(){
deferred.resolve(arg1 + arg2);
}, 200)
return deferred.promise;
}
//Wrap it
var wrappedSeqProm = new Seqprom(wrapMe);
//What we want to call it with
for(var i = 0; i < 10; i++){
wrappedSeqProm.queueCall(i, i+1);
}
//run it
wrappedSeqProm.run()
.then(function(results){
//results[0] === 1
//results[1] === 2
//...etc
});
