Get a value from Nested JSON - javascript

I am completely new to Node.js. I have to read specific value from a API responded Nested JSON. I have tried to figure out but getting Undefined instead of the value. Whenever I am trying to read the base object I am getting the responded value but whenever I am trying to read the object under array then I am getting Undefined value.
Code Snippet:
var https = require('https');
var optionget = {
host: 'api-dev.dataoverflow.com',
port: 443,
path: '/test1/test2/',
method: 'GET',
HEADERS: {
'Authorization': 'Basic grege==',
'X-PruAppID : '
PlainCardPortal '
}
};
console.info(optionsget)
var reqGet = htttps.request(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
res.on('data', function(d) {
process.stdout.write(d);
process.stdout.write(jsonobj);
var Value = jsonobj.items.item.topping.type;
console.log(Value)
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.error(e);
});
var optionsgetmsg = {
host: 'api-dev.dataoverflow.com',
port: 443,
method: 'GET'
};
console.info(optionsgetmsg);
var reqGet = https.request(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
res.setEncoding('utf-8')
res.on('data', function(data) {
process.stdout.write(data);
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.error(e);
});

I want to read type : Glazed from this JSON only but I am getting Undefined.

You have to iterate over the values in an array. You cannot access them using . notation. Use map to iterate over the array and get they types in the topping array
var jsonobj = {
"items": {
"item": [{
"id": "0001",
"type": "donut",
"name": "Cake",
"ppu": 0.55,
"batters": {
"batter": [{
"id": "1001",
"type": "Regular"
},
{
"id": "1002",
"type": "Chocolate"
},
{
"id": "1003",
"type": "Blueberry"
},
{
"id": "1004",
"type": "Devil's Food"
}
]
},
"topping": [{
"id": "5001",
"type": "None"
},
{
"id": "5002",
"type": "Glazed"
},
{
"id": "5005",
"type": "Sugar"
},
{
"id": "5007",
"type": "Powdered Sugar"
},
{
"id": "5006",
"type": "Chocolate with Sprinkles"
},
{
"id": "5003",
"type": "Chocolate"
},
{
"id": "5004",
"type": "Maple"
}
]
}
]
}
}
var Value = jsonobj.items.item.map(e=>e.topping)[0].map(x=>x.type);
console.log(...Value)

How to update a value in a complex fhirBundle JSON?

Given a bewildering fhir document like https://raw.githubusercontent.com/Notarise-gov-sg/api-notarise-healthcerts/master/test/fixtures/v2/pdt_art_with_nric_unwrapped.json
I need to update the part the JSON from { "id": "NRIC-FIN", "value": "S9098989Z" } to { "id": "NRIC-FIN", "value": "foobar" } and then emit the whole JSON again with that change.
I just about know how to access the value.
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value;
console.log(nric);
Though I am puzzled how to update this value since it's so difficult to access. Am I missing a trick? I don't want to use regex btw!
You seem to be very close - why not just set .value using the syntax you already have...?
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value = 'foobar';
console.dir(art.fhirBundle.entry)
... results in:

... clearly showing foobar set as you seem to desire. (Feel free to test with this Repl.it).
To "emit the full JSON" again you would just re-stringify it:
let fullJSON = JSON.stringify(art);
Instead of traversing the object manually you can use library like Jsonpath:
function replace() {
data = JSON.parse(data);
jsonpath.apply(data,
'$.fhirBundle.entry[?(#.resource.resourceType == "Patient")].resource.identifier[?(#.id == "NRIC-FIN")].value',
function(value) {
document.body.innerHTML += `value=${value}<br>`;
return 'foobar';
});
document.body.innerHTML += `updated JSON:<br> <pre>${JSON.stringify(data, undefined, 2)}</pre`;
}
let data =

If you are flat out replacing values without any other logic, and in case if you decide to use RegEx, then you can use String.replace().

}
}`
let targetId = 'NRIC-FIN';
let find = new RegExp(`(?<=${targetId}.*value":\\s*").*?(?=")`, 'ig');
data = data.replace(find, 'foobar');;
document.write(`<pre>${data}</pre>`);
Note: In the regular expression, I have used i flag for case insensitive search. Used g flag to replace all occurrences of the id. If the id is unique and there is going to be only one occurrence in entire .json file then don't use g flag.

How to print huge number of items from the json array

How to dynamically create and iterate Json Object inside a Json Array using Postman - Javascript

I have a payload like mentioned below :
{
"id": "0001",
"type": "donut",
"name": "Cake",
"ppu": 0.55,
"batters": {
"batter": [
{
"id": "1001",
"type": "Regular"
},
{
"id": "1002",
"type": "Chocolate"
},
{
"id": "1003",
"type": "Blueberry"
},
{
"id": "1004",
"type": "Devil’sFood"
}
]
},
"topping": [
{
"id": "5001",
"type": "None"
},
{
"id": "5002",
"type": "Glazed"
},
{
"id": "5005",
"type": "Sugar"
},
{
"id": "5007",
"type": "PowderedSugar"
},
{
"id": "5006",

},
{
"id": "5003",
"type": "Chocolate"
},
{
"id": "5004",
"type": "Maple"
}
]
}
**I want to increment the json objects dynamically(it can be a duplicate as well) which is inside the array topping based on the array size. For example if mention the array size as topping[10] it is suppose to create a payload of 10 objects and push those 10 objects of similar type inside the array topping ** Is it possible to dynamically create json objects and post the request in postman??
Kind note : The size of the array should be parameterized. Please let me know.
Please find the image highlighted in green. I want to dynamically increase the payload(topping array size based on the index using postman
You could do this:
Tab Pre-request
let req = {
"id": "0001",
"type": "donut",
"topping": []
};
let numberOfTopping = 5;
for (let i = 0; i < numberOfTopping; i++) {
let toppingItem = {
"id": `${_.random(5001, 5010)}`,
"type": `${_.sample(["Glazed", "Sugar", "None"])}`
};
req.topping[i] = toppingItem;
}
pm.variables.set("req", JSON.stringify(req));
Tab body
Result
{
"id": "0001",
"type": "donut",
"topping": [
{
"id": "5006",
"type": "Glazed"
},
{
"id": "5001",
"type": "Sugar"
},
{
"id": "5006",
"type": "Glazed"
},
{
"id": "5006",
"type": "None"
},
{
"id": "5008",
"type": "Sugar"
}
]
}

I am just getting the name in here. Can someone please help me how to get Name, Node Name and Phase Values? find the below JSON as well.
Thanks, Much Appreciated
You were close with the code you posted. You just needed items[0] instead of items[1]. Remember the first element of an array is always 0. Other than that its as easy as checking the open and close brackets [] or {} to see where each nested object/array starts and ends.
Code:
var name = data.items[0].metadata.name
var nodeName = data.items[0].spec.nodeName
var phase = data.items[0].status.phase

var data = {

var x =localStorage.getItem("offlinecurries1");
this line returns a string!
you need to parse the string into a json object, add this line right after
var x =localStorage.getItem("offlinecurries1");
x = JSON.parse(x)
Try this. You need to strigify when saving and while retrieving you need to parse the json using JSON.parse so it can be converted back to array.
var json = { "totalSize": 497, "done": true, "records": [{ "attributes": { "type": "PricebookEntry", "url": "/services/data/v36.0/sobjects/PricebookEntry/01u36000001de83AAA" }, "Id": "01u36000001de83AAA", "Name": "P-0025", "Pricebook2Id": "01s36000004AGVLAA4", "Product2": { "attributes": { "type": "Product2", "url": "/services/data/v36.0/sobjects/Product2/01t36000001To1lAAC" }, "Product_Image_URL__c": null, "Description": "ACHAPPAM175GMS X12PKT", "Family": null, "Product_Image__c": "" }, "Product2Id": "01t36000001To1lAAC", "Pricebook2": { "attributes": { "type": "Pricebook2", "url": "/services/data/v36.0/sobjects/Pricebook2/01s36000004AGVLAA4" }, "Name": "UK Pricebook" } }, { "attributes": { "type": "PricebookEntry", "url": "/services/data/v36.0/sobjects/PricebookEntry/01u36000001de84AAA" }, "Id": "01u36000001de84AAA", "Name": "P-0026", "Pricebook2Id": "01s36000004AGVLAA4", "Product2": { "attributes": { "type": "Product2", "url": "/services/data/v36.0/sobjects/Product2/01t36000001To1mAAC" }, "Product_Image_URL__c": null, "Description": "ADA RICE 200 x 30", "Family": null, "Product_Image__c": "" }, "Product2Id": "01t36000001To1mAAC", "Pricebook2": { "attributes": { "type": "Pricebook2", "url": "/services/data/v36.0/sobjects/Pricebook2/01s36000004AGVLAA4" }, "Name": "UK Pricebook" } }] };
