json-chop

Minimal object-to-json formatting and chopping tool.

Installation

npm install --save json-chop

Description

If you don't want rely on libraries like lodash to do minimal object manipulation you can just use JSON.stringify's built-in filter capabilities - or this library, which abstracts a thin layer over it.

This is believed to be much more performant then walking trees.

No dependencies.

Usage

'use strict'
const chop = require('json-chop')
// an arbitrary object
let obj = {
  somekey: {
    nestedKey: 'hello',
    _id: 12234555,
    version: null,
    __v: '0.8.0',
    oneHunrdred: 100
  }
}
// define key and or value you want to finlter. `undefined` and empty
// arrays will be filtered automatically
let options = {
  keyBlacklist: ['__v', '_id'],
  valueBlacklist: ['', 100, null]
}
// async version with a callback
chop.chop(obj, options, (res) => {
  console.log(res)
  // {"somekey":{"nestedKey":"hello"}}
})
// sync version returns the value from the function
let res = chop.chop(obj, options)
console.log(res)
// {"somekey":{"nestedKey":"hello"}}

Roadmap

• ~~Test suite~~
• Type checking for dev input
• optionally return an object
• safe mode (try ... catch)
• Chopping array of nulls
