Add map url to merge - Githubissues

Motivation

I needed a way to only map specific parts of a request response leaving the rest untouched.

New dependencies

deepmerge: used to perform object deep merge react-json-view: used to pretty print, collapse and edit JSON.

Changes

Added functionality to add a "url to merge" mapping. Now is possible to map a url to a deep merge JSON.

Let's say that we have a request that returns:

{
    "a": 1,
    "b": {
        "c": 2,
        "d": 3
    }
}

And we want to merge it with:

{
    "b": {
        "d": 4
    }
}

The result will be:

{
    "a": 1,
    "b": {
        "c": 2,
        "d": 4
    }
}

For arrays it will fully replace the array:

Request:

{
    "a": 1,
    "b": {
        "c": [ 1, 3, 4 ], 
        "d": 3
    }
}

Merge:

{
    "b": {
        "c": [ 3, 4, 5 ]
    }
}

Result:

{
    "a": 1,
    "b": {
        "c": [ 3, 4, 5 ], 
        "d": 3
    }
}
