npm install json2json-transformTransform, set default value and perform operations on JSON objects. Pulls data from an object using JSONPath and generate a new objects based on a template and performs operations on the new JSON object.
``shell`
npm install json2json-transform
`js`
var jsonTojson = require('json2json-transform');
Data
`js`
var data = {
"user": [
{
"userStatus": "ACTIVE",
"userFName": "Tom",
"userLName": "Smith",
"id": 123456789,
"lastUpdated": "2016-03-25T00:13:21Z",
"accountType": "Administrator",
"refreshinfo": {
"statusCode": 0,
"statusMessage": "OK"
},
"balance": {
"amount": 99.99,
"currency": "USD"
}
},
{
"userStatus": "ACTIVE",
"userFName": "Harry",
"userLName": "Pott",
"id": 234567890,
"lastUpdated": "2016-03-25T00:13:21Z",
"accountType": "Power User",
"refreshinfo": {
"statusCode": 0,
"statusMessage": "OK"
},
"balance": {
"amount": 0.00,
"currency": "USD"
}
}
]
};
Template:
`js`
var template = {
"RequestHeader": {
"RequestType": "UserAdd",
"RequestCreatedDate": ""
},
"RqMsg": ['$.user',
{
"RequestID": '$.id',
"RqMsgCreatedDt": '',
"UserRecord": {
"UserId": "$.id",
"UserInfo": {
"UserStatusCode": "$.userStatus",
"UserIdent": {
"UserFirstName": "$.userFName",
"UserLastName": "$.userLName"
},
"UserType": "$.accountType"
},
"UserStatus": {
"StatusCode": "$.refreshinfo.statusCode"
}
}
}
]
}
Operations:
`js
var operate= [
{
run: function () {
var d = new Date();
var n = d.toJSON().toString();
return n;
},
on: "RequestCreatedDate"
},
{
run: function () {
var d = new Date();
var n = d.toJSON().toString();
return n;
},
on: "RqMsgCreatedDt"
}
];
`
Run:
`js`
var result = jsonTojson.transform(data, template, operate);
console.log(JSON.stringify(result));
To set default value just insert the default value in the template. Make sure there is no object with the same name as default value.
Example:
`html`
"RequestType": "UserAdd",
"RequestCreatedDate": "2016-03-25T00:13:21Z"
Pass operations array to the transform
`js
var operate= [
{
run: function () {
var d = new Date();
var n = d.toJSON().toString();
return n;
},
on: "RequestCreatedDate"
},
{
run: function () {
var d = new Date();
var n = d.toJSON().toString();
return n;
},
on: "RqMsgCreatedDt"
}
];
var result = jsonTojson.transform(data, template, operate);
console.log(JSON.stringify(result));
