diggs

A lightweight utility to safely dig into nested properties – because safety is number one priority.

Installation

To install diggs:

npm install --save diggs

That's it!

Why diggs?

diggs allows you to access deeply nested properties without having to worry about undefined properties, null, or TypeErrors.

// Uncaught TypeError: Cannot read property 'foo' of null
// Uncaught TypeError: Cannot read property 'foo' of undefined

Examples

import { get } from 'diggs';

let data = {
  a: {
    b: {
      c: ['foo', { d: 'bar' }],
    }
  },
  z: null,
}

// retrieve deeply nested properties
get(data, 'a.b.c')      // => ['foo', { d: 'bar' }]

// even array items
get(data, 'a.b.c[1].d') // => 'bar'

// returns undefined instead of throwing TypeErrors
get(data, 'z.a')        // => undefined

// returns a default value
get(data, 'z.a', false) // => false

API

get(object, path, defaultValue)

Returns the value at the specified path of object. If the value is not found (undefined), defaultValue will be returned instead.

Arguments

• object (Object): The object to query
• path (String): The path of the property to get
• [defaultValue] (Any): The value returned for undefined values
