program-generator

About

The program generator module takes a specified instruction set and handles managing all new MaM data coming into the stream. If a new message triggers the the "program", it posts an action.

Install

# npm
npm install --save @iftt/program-generator

# yarn
yarn add @iftt/program-generator

How to Use

NOTE: This module assumes the MaM module @iftt/mam has already been instantiated with a provider and ready to request/post messages from/to said provider.

// ES6
import ProgramGenerator from '@iftt/program-generator'
// ES5
const ProgramGenerator = require('@iftt/program-generator').default

// grab the instruction set:
const weatherProgram = require('./test/weatherProgram.json')

const programGenerator = new ProgramGenerator(weatherProgram) // using the default 5 second delay

programGenerator.on('action', action => {
  // do stuff
})

API

Type Service

type Service = {
  protocol: { string: { string: any } },
  getRoot: string
}

Type Program

type Program = {
  condition: Object,
  action: { key: string, value: any }
}

Type Instructions

type Instructions = {
  service: Service,
  program: Program
}

new ProgramGenerator (instructions: Instructions, intervalTime?: number = 5000): ProgramGenerator extends EventEmitter

• instructions: Instructions instruction set to create the program
• intervalTime: number defaults to 5,000 milliseconds (5 seconds); timeout until checking if the latest MaM message update

deconstruct (): void

• null: void used to remove any active intervals looking for new messages
