What would be the ES import equivalent for the following require import.
const {
Parser,
transforms: { unwind },
} = require("json2csv");
Right now i am doing it in multiple steps , but is it possible to do that at once in a single line.
import { Parser, transforms } from "json2csv";
const { unwind } = transforms;

How to use TypeToken + generics with Gson in Kotlin

I have JSON string as below
var purchases = "[{\"contentId\":\"861723b2-78e4-42ea-8479-40fa0850c314\",\"purchaseType\":\"RENT\"},{\"contentId\":\"138bc762-b539-4749-8706-de2f0eea4b61\",\"purchaseType\":\"PURCHASE\"}]"
I am trying to convert it into list of data class objects
val userPurchases: List<UserPurchases> = Gson().fromJson(purchases,List<UserPurchases>)
This is my data class
data class UserPurchases(
val contentId: String,
val purchaseType: String)
Solved by below
val purchase: List<UserPurchases> = GsonBuilder().create().fromJson(userPurchases, Array<UserPurchases>::class.java).toList()

How to parse JSON in Java

I know this topic was discussed pretty often and I guess it is not a diffucult thing.
I want to use a JSON Object from my session in a JSP. The Object has the following structur:
{
"addedUsers":[
{
"city":"Los Angeles",
"name":"Doe",
"forname":"John",
"title":"Dr.",
"userId":2
}
],
"allUsers":[
{
"city":"Los Angeles",
"name":"Doe",
"forname":"John",
"title":"Dr.",
"userId":2
},
{
"city":"New York",
"name":"Peter",
"forname":"Parker",
"title":"Dr.",
"userId":3
}
]
}
Now I want to grab the Objects by name for example doing a for each on the "addedUsers" Object and grab the properties. It is important not just to iterate over the whole Object. I have to call them by name.

I'm receiving a json object that has a known-static structure inside a key that varies between 10 different values.
Consider lastname can be any in a list of 10 lastnames:
var lastnames = [...]string { "Smith", "Johnson", "Williams", "Brown", "Jones", "Miller", "Davis", "Garcia", "Rodriguez", "Wilson" }
Now, this is how the json looks:
{
(lastname here):
{
"position": value,
"user_email": value
}
}
I tried to unmarshall it using the following structs, but I only get null values:
type Inside struct {
Rol string `json:"position"`
Email string `json:"user_email"`
}
type Outside struct {
Key Inside
}
...
var outside Outside
json.Unmarshal([]byte(body), &outside)
Is it possible to unmarshall this directly without creating 10 different structs? Is there possible workaround?

How to parse JSON using Node.js? [closed]

Closed 4 years ago.
I want to validate a JSON object without the help of any libraries in nodejs.
Just by parsing it, using JSON.parse function:
function isValidJSON(text){
try{
JSON.parse(text);
return true;
}
catch (error){
return false;
}
}
console.log(isValidJSON("hello")); // false
console.log(isValidJSON("{}")); // true

Safely turning a JSON string into an object
(28 answers)
Closed 5 years ago.
I have this JS object:
{ validator: myValidator }
myValidator is a java JAVASCRIPT function NAME that will be declared somewhere else. I am planning to use it like:
<TableHeaderColumn dataField='status' editable={ { validator: myValidator } }>Job Status</TableHeaderColumn>
where TableHeaderColumn is a react component. So, the question is: What is the JSON string that after using JSON.parse or a similar command I will obtain the { validator: myValidator } object where myValidator is "the name of a function", not a string. This is not clear for me inclusive at the referenced solution.
To convert a JS Object to JSON, you can use json = JSON.stringify(jsObject)
To convert JSON to a JS Object, just use jsObject = JSON.parse(json)
