i11e robot

Usage:

create a robot

You can create a new Robot model with createRobot method

const Robot = require('i11e-robot');

var MyRobot = Robot.createRobot({
  initRobot() {
    // optional, init your robot here
    console.log(this.options);
  },

  getModel() {
    return 'MyRobotModel';  // optional, the model name. default: Unnamed Robot
  },

  isSync() {
    return false;   // optional, if the robot works in sync model, default: false;
  },

  process(box, done) {
    // process the box and return it with done callback (async mode)
    done(null, box);  // accepts an error and the return box
  }
});

var robotInstance = new Robot({
  //options
});

create a sync robot

You can create a sync robot with isSync() method returning true. In sync mode, the process(box) method does not accept the second callback function, instead, it returns the box directly.

const Robot = require('i11e-robot');

var MySyncRobot = Robot.createRobot({
  getModel() {return 'MySyncRobot'},
  isSync() {return true},
  process(box) {
    box.set('v', 100);
    return box;
  }
});

var mySyncRobot = new MySyncRobot();

create a filter

A filter is a special robot, which returns a boolean value to indicate if the box need to be processed or not. You need to implement the isFilter() method and return true to turn the robot in filter mode.

Note: a filter MUST work in sync mode, you don't need to implement the isSync() method, as it will automatically set to true when working in filter mode.

const Robot = require('i11e-robot');

var MyFilter = Robot.createRobot({
  isFilter() {return true},
  process(box) {
    return box.get('v') > 100; // only process the box with v greater than 100
  }
});

var myFilter = new MyFilter();

shortcuts to create robot/filter

Besides the createRobot method, there are three shortcut methods to help you create robot / filter.

• Robot.robot(fn, options)
• Robot.filter(fn, options)

Robot.robot(fn, options)

Create a robot instance with a function

• fn: function (box, done) if options.sync = false otherwise function (box)
• options:
  • name: the name of the robot
  • model: the model of the robot
  • comment: the comment of the robot
  • sync: the working mode of the robot, default false

const Robot = require('i11e-robot');
var myRobot = Robot.robot((box, done) => {
  box.set('greeting', 'Hello World!');
  done(null, box);
});

Robot.filter(fn, options)

Create a filter robot with a function

• fn: function (box, done) if options.sync = false otherwise function (box)
• options:
  • name: the name of the robot
  • model: the model of the robot
  • comment: the comment of the robot

const Robot = require('i11e-robot');
var filter = Robot.filter((box) => {
  return box.get('v') > 100;
});
