JSPM – reiterator@1.0.0

Package Exports

reiterator

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (reiterator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ReIterator is a node.js module which helps you avoid errors while accessing json from the big bad internet (and your own apis)

About

I created this package to simplify iterating across arrays and objects without hitting into errors. The Iterator is chainable, making it possible to access items as i.$('first').$(0).$('second).value()

Quick Start

yarn install reiterator

const i = require('reiterator')
const value = i.Iterator({'key': 'abc'})
console.log(value)

The response should be abc

The complete API

Iterator functions

The package supports the following functions on the iterator

const obj = { 'abc': [1,2,3,4,5], 'def': { 'ghi': 'jkl', 'mno': 10 }}
i = new Iterator(obj)
i.$('abc').keys() // [1,2,3,4,5]
i.$('def').keys() // []
i.$('def').$('ghi').string() // 'jkl'
i.$('def').$('mno').string() // '10
i.$('def').$('mno').value() // 10

What makes it easy is that

keys() always returns an array or []
string() always returns a string or ''

Object functions

The package support the following functions on objects

const array = i.objects.isArray([123])
const object = i.objects.isObject({ 'key': 'abc'})
const number = i.objects.isNumber(123)
const string = i.objects.isString('asdf')
const hasKey = i.objects.hasKey({'abc':'def'}, 'abc')
