deepmerge2

Merge the enumerable attributes of two objects deeply.

What's the difference between deepmerge and deepmerge2?

Reason of creating this fork is inactivity of original deepmerge plugin. This version has several bug fixes.

example

var util = require('util');
var merge = require('deepmerge2');

var x = {
  foo: { bar: 3 },
  array: [ { does: 'work', too: [ 1, 2, 3 ] } ]
};
var y = {
  quux: 5,
  foo: { baz: 4 },
  array: [ { does: 'work', too: [ 4, 5, 6 ] }, { really: 'yes' } ]
};

console.log(util.inspect(merge(x, y), false, null));

output:

{
  quux: 5,
  foo: { bar: 3, baz: 4 },
  array: [ { does: 'work', too: [ 1, 2, 3, 4, 5, 6 ] }, { really: 'yes' } ]
}

methods

var merge = require('deepmerge2');

merge(x, y)

Merge two objects x and y deeply, returning a new merged object with the elements from both x and y.

If an element at the same key is present for both x and y, the value from y will appear in the result.

The merge is immutable, so neither x nor y will be modified.

The merge will also merge arrays and array values.
