nv-facutil-reactivize

• nv-facutil-reactivize is a very simple util to make methods-of-Class listenable

install

• npm install nv-facutil-reactivize

usage

  const {reactivize,CMMN_METHODS_FILTER} = require("nv-facutil-reactivize");
  
  //reactivize(PCls,specific_fltr,cmmn_fltr)
  //PCls : Parent-Class
  //specific_fltr: filter-of-methods-in-parent-class
  //cmmn_fltr:     common-filter,such as construtcor

example

//specific_fltr for Array
const ARRAY_METHODS_FILTER = []

var RArray = reactivize(Array,ARRAY_METHODS_FILTER,CMMN_METHODS_FILTER)

var arr = new RArray()

//listen for push method
// e.data = {rslt:<the returned rets>,params:<the arguments>}
//
arr.regis_$push$_handler(e=>{console.log(e,e.data)})

> arr.push(10)

  type: 'push',
  defaultPrevented: false,
  cancelable: false,
  timeStamp: 49738.11588096619
