Outlet

Plugin architecture w/ control flow model

WIP: Do not use! Unlicensed

Features

Hierarchical stack syntax for triggers

Example

outlet.trigger('math/count/inc');

Triggers the follow stack. Calls an ordered control flow stack with passable arguments between functions in the stack. After the control flow registered listeners are called with the arguments object.

[ '*:before',
  'math:before',
  'math/*:before',
  'math/count:before',
  'math/count/*:before',
  'math/count/inc:before',
  '*',
  'math',
  'math/*',
  'math/count',
  'math/count/*',
  'math/count/inc',
  'math/count/inc:after',
  'math/count/*:after',
  'math/count:after',
  'math/*:after',
  'math:after',
  '*:after' ]

Simple control flow

Trigger the control flow with initial arguments and log our results

var args = {count: 1};
outlet.trigger('math/count/inc', args);
console.log(args);
// {count: 2}

Export the increment function from our plugin (index.js)

module.exports = {
    increment: function(outlet, args) {
        // get 'step' config value from test plugin
        var step = outlet.settings.get('device:test:increment:step');

        // init count if not passed
        args.count = args.count?args.count:0;
        // increment count by step
        args.count = args.count+step;

        // trigger the next workflow with updated args
        outlet.next(outlet, args);
    }
};

Declare our settings and 'wiring' in our plugins package.json

{
  "name": "device-inc",
  "version": "0.2.0",
  "device": {
    "settings": {
      "increment": {
        "step": 1
      }
    },
    "wiring": [
      {
        "type": "workflow",
        "trigger": "math/count/inc",
        "action": "increment"
      }
    ]
  },
  "main": "index.js"
}
