Key Mirror Nested

Tiny helper to create const in js, just like react/lib/keyMirror, but support nested object and more features.

Install

npm install key-mirror-nested --save

Usage

`` js
var keyMirror = require('key-mirror-nested');

var options = {
connChar: '.',
// connect char, default use '.'
custFunc: function(oldVal, newVal) {
return newVal;
}
// cust const val before replace
};

var OUTPUT_OBJ = keyMirror(inputObj, options);
`

Example

` js
var keyMirror = require('key-mirror-nested');

var DUMMY_CONST = {
ACTIONS: {
LOGIN: {
SUCCESS: null,
ERROR: undefined
},
SOME_OTHER_ACTION: ''
},
EVENTS: {
A: 123,
B: 456
},
SOME_OTHER: 789
};

console.log(keyMirror(DUMMY_CONST));
/*
=>
{
ACTIONS: {
LOGIN: {
SUCCESS: 'ACTIONS.LOGIN.SUCCESS',
ERROR: 'ACTIONS.LOGIN.ERROR'
},
SOME_OTHER_ACTION: 'ACTIONS.SOME_OTHER_ACTION'
},
EVENTS: {
A: 'EVENTS.A',
B: 'EVENTS.B'
},
SOME_OTHER: 'SOME_OTHER'
}
*/
`
with options:
` js
var keyMirror = require('key-mirror-nested');

var DUMMY_CONST = {
ACTIONS: {
LOGIN: {
SUCCESS: null,
ERROR: undefined
},
ACTIONB: ''
},
EVENTS: {
A: 123,
B: 456
},
SOMEOTHER: 789
};

console.log(keyMirror(DUMMY_CONST, {
connChar: '_',
custFunc: function(oldVal, newVal) {

// you can do something with const val here
if(typeof(oldVal) === "number") {
newVal = newVal + '_' + oldVal
}

return newVal;
}
}));

/*
=>
{
ACTIONS: {
LOGIN: {
SUCCESS: 'ACTIONS_LOGIN_SUCCESS',
ERROR: 'ACTIONS_LOGIN_ERROR'
},
ACTIONB: 'ACTIONS_ACTIONB'
},
EVENTS: {
A: 'EVENTS_A_123',
B: 'EVENTS_B_456'
},
SOMEOTHER: 'SOMEOTHER_789'
}
*/
