asyncSeries.setArgs(/*args*/)
	.setErrorHandler(/*handler function*/);

setArgs

Set the arguments passed through every function. Can passed multiple arguments.

setErrorHandler

Set the handler function to handle error thrown by next(err).

Asynchronous Function

The last argument of target function must be a function next.(Similar to Express)

Example

var flow = require('asynchronous-flow');

function func1(arg, next){
	console.log(arg.val++);
	next();
}

function func2(arg, next){
	console.log(arg.val++);
	next('error test');
}

var args = {val: 0};

var tmp = new flow();
tmp.setArgs(args)
	.setErrorHandler((err) => {console.log('Error : ', err)})
	.flow(func1, func2, (arg) => {
		console.log(arg.val);
	});
