dot-values

dot-values is a collection of dot path object mutators (get-value, has-value, set-value, unset-value) with one neat addition...

You can query arrays of objects

const _ = require('dot-values')
 
let request = {
    header: {
     content_type: 'application/json'
    },
    body: {
     parts: [
            {
             content: '...',
                featured: true
            },
            {
             content: '!!!'
            }
        ]
    }
}
 
_.get(request, 'header.content_type')
// "application/json"
 
_.get(request, 'body.parts.1.featured')
// true
 
_.get(request, 'body.parts.*.content')
// ['...', '!!!']
 
_.has(request, 'body.parts.*.featured')
// false
// only true if all items have the attribute
 
_.set(request, 'body.parts.*.bool', true)
// now all parts would have an attribute bool: true
 
// but you can go even deeper like
_.get(request, 'body.users.*.permissions.*.name')
// ['admin', 'editor', 'publisher', 'admin' ...]
// be aware that this does not return unique values, but all the values in order
// if you want unique values though, you can do something like
// https://stackoverflow.com/questions/1960473/get-all-unique-values-in-an-array-remove-duplicates

So just to clarify, you can reference arrays of objects with an asterisk (*).

Also _.get takes a default return value as the third argument (that applies to array values too).

Otherwise everything works as the original modules.
