Dot Object Expander

A small module that expands object keys with dot notation into full objects.

It is a simple recursive wrapper around the dot-object library dot.object method. It also checks for circular references before attempting to parse.

This was built primarily to parse API nested object queries into proper format for MongoDB, as some versions of MongoDB drivers do not support dot notation in key names.

Installation

npm i @thefoot/dot-object-expander --save

Usage

NodeJS

const dotObjectExpander = require ( '@thefoot/dot-object-expander' );

console.log( dotObjectExpander ( {
    string         : 'bar',
    int            : 123,
    float          : 1.234,
    boolean        : true,
    'obj.foo'      : {
        'bar.baz': 123
    },
    'org.user.type': {
        admin: {
            'has.permissions.admin': true
        },
        ary  : [ 1, 2, 3 ]
    }
} ) );

// Result:
{
    "string": "bar",
    "int": 123,
    "float": 1.234,
    "boolean": true,
    "obj": {
        "foo": {
            "bar": {
                "baz": 123
            }
        }
    },
    "org": {
        "user": {
            "type": {
                "admin": {
                    "has": {
                        "permissions": {
                            "admin": true
                        }
                    }
                },
                "ary": [
                    1,
                    2,
                    3
                ]
            }
        }
    }
}

ES Module

ES Module-aware environments such as Webpack and Rollup bundlers should automatically use the dist/parser.esm.js export.

import dotObjectExpander from '@thefoot/dot-object-expander';

dotObjectExpander({
    'org.user.type': {
        admin: {
            'has.permissions.admin': true
        },
        ary  : [ 1, 2, 3 ]
    }
});
