Node.js: Extract data from JSON response

Question

I'm fetching product details using an API which gives the response as a JSON object.

{
    "productBaseInfo": {
        "productIdentifier": {
            "productId": "EKTDDD23232zYHR94E4",
        },
        "productAttributes": {
            "title": "Nova KT 72BC 1 Electric Kettle",
            "imageUrls": {
                "400x400": "http://img5a.flixcart.com/image/electric-kettle/4/e/4/nova-kt-722-c-kt-722c-400x400-imadddh2fdvuzpxz.jpeg",
                "75x75": "http://img6a.flixcart.com/image/electric-kettle/4/e/4/nova-kt-722-c-kt-722c-75x75-imadddh2fdvuzpxz.jpeg",
            },
            "sellingPrice": {
                "amount": 599.0,
                "currency": "INR"
            },
            "productUrl": "http://dl.mykart.com/dl/nova-kt-722c-1-electric-kettle/p/itmdddf398rhhhz2?pid=EKTDDDEGXYHR94E4&affid=userid"
        }
    }
}

Now I want to get the productId, title in ProductAttributes, and all the image urls and productURL. I tried

var productURL = JSON["productAttributes"].productUrl

But it returns an error productUrl not found error. Looking for suggestion on how to extract the data. Thanks in advance.

productAttributes is inside productBaseInfo. So you need to access it like this

console.log(JSON.productBaseInfo.productAttributes.productUrl);
// http://dl.mykart.com/dl/nova-kt-722c-1-electric-kettle/p/itmdddf398rhhhz2?pid=EKTDDDEGXYHR94E4&affid=nikhilgeo

Thanks for the reply. I tried this out but I'm getting an error " TypeError: Cannot read property 'productAttribures' of undefined.

Can you show the actual code which you tried? I think you are getting it as a string.

Hey I got it right I forgot to convert the json object to javascript object. Now it works fine.. Thank you very much

In case of imageurls: To retrive it I used jsObject.productBaseInfo.productAttributes.imageUrls.400*400; but node.js shows SyntaxError:Unexpected token ILLEGAL error at 400*400. How could I get image link with out refering to 400*400

@NikhilGeorge * is not a valid character for an attribute name, so you should access it like this jsObject.productBaseInfo.productAttributes.imageUrls["400*400"]
