ExecStack

Installation

$ npm install exec-stack

Example

var ExecStack = require('exec-stack');

var stack = new ExecStack();

stack.push(function(next) {
    console.log('This is called for every execution of the stack!');
    next();
});

stack.push('event', function(next) {
    console.log('This is called whenever `event` is being executed!');
    next();
});

stack.execute(); 
// OUTPUT: This is called for every execution of the stack!

stack.execute('event');
// OUTPUT: This is called for every execution of the stack!
// OUTPUT: This is called whenever `event` is being executed!

Options

Options are passed to the constructor.

strict (false)

If true, only functions subscribed to the executed event are being called by .execute().

Methods

Optional arguments are written in cursive.

.push(event, callback)

Push a function on the stack. If event is ommited, the callback will be called for every execution of the stack. Returns the position of the item in the stack.

.remove(item)

Removes a specified item from the stack. The item is being referenced by a number representing its position, just like in an array.

.execute(event, callback, context, [...])

Execute the stack in the given context (context is set to an empty object by default). If callback is a function, it will be called when the stack has finished.
Any other argument that is given to .execute() will also be passed to the functions in the stack.
