##PDP JSON Layouting

###Basic Structure of JSON Layout

We'll refer the following structure as a node. A node is an equivalent of HTML Node (e.g, <div>, <span> ..)

{
  "type"  : "...",
  "value" : "...",
  "attr"  : {},
  "children": [
     {}
   ]
}

type, value, attr, children.. are node attributes, where,

• type - type of node, which can be one of [type]
• value - value of node, which can be one of [value]
• attr - the list of attributes for current node
• children - list of nodes to be wrapped inside current node

Apart from the above attributes, node type column has special attributes,

• width - in case of type as column use width to specify the column width e.g, 12, {"small": 6, "medium": 12}
• visible - visibility options for column e.g, ["large", "medium"]
• variations - used to specify push, pull, offset width e.g, {"offset": 2}, {"push": 3}

NOTE

• In JSON format , will not be there for last attribute, the rest of the lines will end with a ,

###Analogy between JSON Node and HTML node

Consider the following simpe HTML markup

<div id="title" data-catalog-sku="SM-S3-NEO-I9300">
</div>

Lets see the JSON equivalent of following:

1. Create a JSON with type as html_tag and value as div

{
  "type": "html_tag",
  "value": "div"
}

2. Lets add attribute to the node, HTML attributes of a tag can be specified in attr attribute of the node

{
  "type" : "html_tag",
  "value": "div",
  "attr" : {
    "id" : "title",
    "data-catalog-sku":"SM-S3-NEO-I9300"
  }
}

In the above example to get a <span> instead of <div> we just need to replace "value": "div" with "value": "span", similarly for any html tag. Consider a complex html markup,

<div class=" row">
  <div class="col-md-5 col-sm-5">
  </div>
  <div class="col-md-7 col-sm-7">
  </div>
</div>

Lets create the JSON equivalent of the above HTML,

1. The below node makes up for a row

{
  "type": "row"
}

2. The below node makes up for a 5 column

{
  "type": "column",
  "width": 5
}

3. The below node makes up for a 7 column

{
  "type": "column",
  "width": 7
}

4. All we have to do is to make 5-column and 7-column node as a children of row. The final JSON will look like

{
  "type": "row",
  "children": [
    {
      "type": "column",
      "width": 5
    },
    {
      "type": "column",
      "width": 7
    }
  ]
}

5. What if we needed to add classes for breakpoint like below

<div class=" row">
  <div class="col-md-5 col-sm-6 col-xs-6">
  </div>
  <div class="col-md-7 col-sm-6 col-xs-6">
  </div>
</div>

Simple, pass breakpoint widths to width as,

{
  "type": "column",
  "width": {
    "large" : 5,
    "medium": 6,
    "small" : 6
  }
}

The equivalent JSON with column breakpoint widths is,

{
  "type": "row",
  "children": [
    {
      "type": "column",
      "width": {
        "large" : 5,
        "medium": 6,
        "small" : 6
      }
    },
    {
      "type": "column",
      "width": {
        "large" : 7,
        "medium": 6,
        "small" : 6
      }
    }
  ]
}

NOTE

• The type of children is always Array []
• In JSON layout,
• • large corresponds to md
• • medium corresponds to sm
• • small corresponds to xs

                }
              ]
            }
          ]
        },

        },

          "width": 4
        }
      ]
