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 data =
`{ "identifier": [
{
"id": "PPN",
"type": {
"coding": [
{

],

"gender": "female",
"birthDate": "1990-01-15"
}
}`
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 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",
"type": "ChocolatewithSprinkles"
},
{
"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"
}
]
}

Get a value from Nested JSON

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);

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",

{
"id": "1002",
"type": "Chocolate"
},
{
"id": "1003",
"type": "Blueberry"

{
"id": "1004",

var Value = jsonobj.items.item.map(e=>e.topping)[0].map(x=>x.type);

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.

I have a json object that I obtained from drafter and I only want the schema

I am using node to call drafter in order to generate the json schema for an application. My goal is to get rid of all the extra output that is spit out by drafter. I end up with a huge thing of json but I only need a small portion of it.
This is what is output:

The bit below is what I need.
content = {
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"question": {
"type": "string"
},
"published_at": {
"type": "string"
},
"url": {
"type": "string"
},
"choices": {
"type": "array"
}
},
"required": [
"question",
"published_at",
"url",
"choices"
]
}
This is the code I have as of right now and it is not working the way I am envisioning. If you need any more information to help me please ask.
App.js
var fs = require('fs');
var edit = require('string-editor');
var lodash = require('lodash');
var _ = require('underscore');
const util = require('util');
const exec = require('child_process').exec;
exec('drafter -f json test.apib' , function(error, stdout, stderr) {
const json = JSON.parse(stdout);
//console.log(json)
var res
function loopThrough(obj){
for(var key in obj){
if(!obj.hasOwnProperty(key)) continue;
if(typeof obj[key] !== 'object'){
//if (cond) var x = {'$schema': };
//if (_.hasIn(obj, '$schema')) {
res = res + "\n" + (key+" = "+obj[key]);
//}
} else {
loopThrough(obj[key]);
}
}
}
loopThrough(json);
//parse = JSON.parse(test);
//string = JSON.stringify(test, null, ' ');
//string = string.replace(/\\n/g, '');
fs.writeFile('test.json', res, function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});
if (error !== null) {
console.log('exec error: ' + error);
}
});
This is the ouput I am down to.

You could try running it through an online JSON schema generation tool like this: http://jsonschema.net/#/
You will also want to consider reading up on the proposed JSON Schema specification here: http://json-schema.org/documentation.html
UPDATED: If you would like to generate the schema at runtime via Node, you could leverage a module like json-schema-generator.
UPDATED AGAIN: I am not sure I follow you but, from looking at your data, you should be able to use the following to grab all content with the contentType of application/schema+json like so:
var _ = require('lodash');
var schemas = [];
function isSchemaType(contentItem) {
return _.get(contentItem, 'attributes.contentType') == 'application/schema+json';
}
function parseContent(content) {
if (_.isObject(content) && _.isArray(content.content)) {
_.forEach(content.content, parseContent);
} else if (isSchemaType(content)) {
schemas.push(JSON.parse(content.content));
}
}
parseContent(jsonData);
console.log(schemas);
Here is a working jsfiddle: https://jsfiddle.net/k7dcd6s2/
