Valky

A simple utility to deep search an object and return a key of a value.

Quickstart

Install the module from npm as shown

npm install valky

Define an object as shown

var myObject = {
    name: 'Application',
    port: 9001,
    database: {
        host: 'localhost',
        ports: {
            one: 27012,
            two: 27013
        },
        user: 'user',
        pass: 'pass'
    }
};

To get the key of a specific value, use the valky lib as shown

var valky = require('valky');
 
var appKey = valky(myObject, 'Application');
var dbUserKey = valky(myObject, 'user');
var dbPassKey = valky(myObject, 'pass');
 
var dbHostOne = valky(myObject, 27012);
var dbHostTwo = valky(myObject, 27013);
 
console.log(appKey);
console.log(dbUserKey);
console.log(dbPassKey);
 
// Logs out name
// Logs out database.user
// Logs out database.pass
 
console.log(dbHostOne);
console.log(dbHostTwo);
// Logs out database.ports.one
// Logs out database.ports.two

Valky also works with custom delimiters, specify it as a third parameter.

var valky = require('valky');
 
var dbHostOne = valky(myObject, 27012, '_');
var dbHostTwo = valky(myObject, 27013, '_');
 
console.log(dbHostOne);
console.log(dbHostTwo);
// Logs out database_ports_one
// Logs out database_ports_two

NOTE: If the value of two keys are same, the key-val pair first detected takes precedence.
