Xorderedlist NPM

XOrderedList

A useful tool to manage array of object.

Introduction

Sometimes it would be a headache to maintain and to manipulate an array of object. ListStore is just a Map wrapper Object that enhances the original Map object. It looks like a small "database" which will help you manage arrays in a rather comfortable way.

How to use it

install

npm install xorderedlist

example

import OrderedList from 'xorderedlist'

const list = new OrderedList([{ id: 1, name: 'one' }])
console.log(list.size) // 1

list.push([{ id: 2, name: 'two' }])

list.unshift([{ id: 0, name: 'zero' }])

list.update([{ id: 1, name: 'update one'}])

list.insertOne({id: 1.5, name: 'one point five' }, 1)

list.delete([2])

list.findOne(0)

list.findList([1, 2])

list.mutate((orderedList) => {
  return orderedList.values.map(v => {
    v.name = 'mutate ' + v.name
  })
})
