# Ember JSON Mapper

### What is it?

Small mapper for JSONs. It allows you to convert one object to another with minimal effort.

### Installing

````

bower i ember-json-mapper

````

### Usage examples

Basic

````javascript

var map = { a: 'a', c: 'b' };

var source = { a: 1, b: 2 };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, c: 2 }

````

Nested objects

````javascript

var map = { a: 'a', d: 'b.c' };

var source = { a: 1, b: { c: 2 } };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: 2 }

````

Nested keys

````javascript

var map = { a: 'a', 'd.e': 'b' };

var source = { a: 1, b: 2 };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: { e: 2 } }

````

Nested objects and nested keys

````javascript

var map = { a: 'a', 'd.e': 'b.c' };

var source = { a: 1, b: { c: 2 } };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: { e: 2 } }

````

Objects as keys

````javascript

var map = { a: 'a', c: { key: 'b' } };

var source = { a: 1, b: 2 };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, c: 2 }

````

With default value

````javascript

var map = { a: 'a', c: { key: 'b', default: 3 } };

var source = { a: 1, b: 2 };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, c: 2 }

````

Set value without mapping from source

````javascript

var map = { a: 'a', c: { default: 3 } };

var source = { a: 1, b: 2 };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, c: 3 }

````

Custom getter

````javascript

var map = { a: 'a', 'b': { custom: function (source) {

  return Ember.get(source, 'b.c') + 1;

} } };

var source = { a: 1, b: { c: 2 } };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, b: 3 }

````

Array-properties mapping

````javascript

var map = { a: 'a', d: { key: 'b', map: { c: 'c' } } };

var source = { a: 1, b: [

  {c: 1, d: 1},

  {c: 2, d: 2}

] };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: [ {c: 1}, {c: 2} ] }

````

````javascript

var map = { a: 'a', d: { key: 'b', map: { c: 'c', f: { default: 2 } } } };

var source = { a: 1, b: [

  {c: 1, d: 1},

  {c: 2, d: 2}

] };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: [ {c: 1, f: 2}, {c: 2, f: 2} ] }

````

Multi-nesting

````javascript

var map = { a: 'a', d: { key: 'b', map: { c: 'c', v: { key: 'd', map: { e1: 'e', f1: 'f' } } } } };

var source = { a: 1, b: [

  {c: 1, d: [

    { e: 3, f: 4 }

  ] },

  {c: 2, d: [

    { e: 5, f: 6 }

  ] }

] };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: [ {c: 1, v: [ { e1: 3, f1: 4 } ] }, {c: 2, v: [ { e1: 5, f1: 6 } ] } ] }

````

Custom getter for nested objects

````javascript

var map = { a: 'a', d: { key: 'b', map: { c: 'c', v: { key: 'd', map: { e1: 'e', f1: { custom: function(source) {

  return Ember.get(source, 'f') + 1;

} } } } } } };

var source = { a: 1, b: [

  {c: 1, d: [

    { e: 3, f: 4 }

  ] },

  {c: 2, d: [

    { e: 5, f: 6 }

  ] }

] };

var expected = { a: 1, d: [

  {c: 1, v: [

    { e1: 3, f1: 5 }

  ] },

  {c: 2, v: [

    { e1: 5, f1: 7 }

  ] }

] };

var mapped = Ember.JsonMapper.map(source, map); // { a: 1, d: [ {c: 1, v: [ { e1: 3, f1: 5 } ] }, {c: 2, v: [ { e1: 5, f1: 7 } ] } ] }
