Filter nested array with objects given a certain ID

I need to get data from a nested array of objects, given an ID that I have.
I have been trying to get data from it so that I can pass it in to Angular Gridster 2, but even when using array.filter, I am struggling to get the results I want.
Data I start with:
[
{
"0": {
"cols": 15,
"id": "5-1564645705217",
"rows": 7,
"type": 0,
"x": 0,
"y": 0
},
"1": {
"cols": 15,
"id": "5-1564645705217",
"rows": 7,
"type": 1,
"x": 15,
"y": 0
},
"2": {
"cols": 15,
"id": "5-1564645705217",
"rows": 8,
"type": 2,
"x": 0,
"y": 7
},
"id": "1zk66HvI97C03751LNQm"
},
{
"0": {
"cols": 5,
"id": "5-1564545",
"rows": 7,
"type": 0,
"x": 0,
"y": 0
},
"1": {
"cols": 5,
"id": "5-1564545",
"rows": 7,
"type": 1,
"x": 15,
"y": 0
},
"id": "8gdfg897C03751LNQm"
}
]
I have an id (such as 1zk66HvI97C03751LNQm) and want to be able to fetch the contents so that I end up with:
[
{
"cols": 15,
"id": "5-1564645705217",
"rows": 7,
"type": 0,
"x": 0,
"y": 0
},
{
"cols": 15,
"id": "5-1564645705217",
"rows": 7,
"type": 1,
"x": 15,
"y": 0
},
{
"cols": 15,
"id": "5-1564645705217",
"rows": 8,
"type": 2,
"x": 0,
"y": 7
}
]

Using Array.prototype.find you can easily locate element you want (granted it will only return first found entry, so if your id can be non unique you should use filter instead) after which i remove id from the found object, and turn the rest of the data into desired format.
const data = [{"0": {"cols": 15, "id": "5-1564645705217", "rows": 7, "type": 0, "x": 0, "y": 0}, "1": {"cols": 15, "id": "5-1564645705217", "rows": 7, "type": 1, "x": 15, "y": 0}, "2": {"cols": 15, "id": "5-1564645705217", "rows": 8, "type": 2, "x": 0, "y": 7}, "id": "1zk66HvI97C03751LNQm"}, {"0": {"cols": 5, "id": "5-1564545", "rows": 7, "type": 0, "x": 0, "y": 0}, "1": {"cols": 5, "id": "5-1564545", "rows": 7, "type": 1, "x": 15, "y": 0}, "id": "8gdfg897C03751LNQm"}]
const searchId = "1zk66HvI97C03751LNQm";
const {id, ...elementFound} = data.find(({id})=> id === searchId) || {}; // skip id as unnecessary, return empty object in case of no entries matching search criteria
const elementParsed = Object.values(elementFound); // get values of other fields
console.log(elementParsed);

Check properties that changed since last interval in NodeJS

In nodeJS, let's say that I have a little setInterval:
setInterval(() => {
// ...
}, 50)
And it sends to client entities:
setInterval(() => {
socket.emit("entities", { ... })
}, 50)
Entities looks like this:
{
"0": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 1970,
"y": 1477
},
"uid": 0,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
},
"1": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 1240,
"y": 1866
},
"uid": 1,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
},
"2": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 2195,
"y": 2034
},
"uid": 2,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
}
}
How do I, at every interval, only send updated properties from the all entities, and if all the entity didn't change, only send true?
Received entities should look like this:
{
"0": true,
"1": {
"health": 99,
"position": {
"x": 1245, /** position and health changed, send them **/
"y": 1866 /** even if only the x changed, send y too **/
}
},
"2": true /** all the entity stayed the same, so send `true` **/
}

Node Red smart Thermostat

I need help with increments in Node Red (on Raspberry Pi). I am trying to make a smart thermostat with a LCD touchscreen and an app for remote access (ex. coming home on a cold winter day and want to start heating your apartment).
Some suggestions on how to connect to the Raspberry Pi over the Internet (not local network) with an android and a link on a tutorial or example would be much appreciated.
P.S. I am doing this for a friend and I promised him some good results.
Sorry for messy code... => cleaned it up in the edit
I have tried everything I could think of to make my code work as I am not very experienced with NodeRed nor JS.
Global variables May just do the trick... I haven't figured it out yet...
Another barrier I have encountered is the ability to access and interact with the code outside the local network.

The old thermostat was basically an automated relay switch. I have to make it smart and my best bet is a raspberry pi.
The increment part can replace the slider(I have Backups) and has to be triggered by a button in the Dashboard UI.
Everything except of what I mentioned works corectly.
Thank you for your help!! (or at least your time)

How to delete an object from Javascript object

I'd like to delete an object element from an object. I have tried the following but it returns the same without deleting an element. jsfiddle. I am trying to delete clock object.
How can I delete it?
var position = '{"weather":{"id":"weather","x":0,"y":0,"width":12,"height":9},"google_calendar":{"id":"google_calendar","x":0,"y":10,"width":12,"height":9},"clock":{"id":"clock","x":0,"y":19,"width":3,"height":3},"todo":{"id":"todo","x":3,"y":19,"width":6,"height":4}}';
var name = "clock";
console.log(position);//before delete
delete position.name;
//delete position.name;
console.log(position);//after delete
I'd like to achieve this.
{"weather":{"id":"weather","x":0,"y":0,"width":12,"height":9},
"google_calendar{"id":"google_calendar","x":0,"y":10,"width":12,"height":9},
"todo":{"id":"todo","x":3,"y":19,"width":6,"height":4}}

First off position is a string, not an object.
Second off, position.name operates on the .name property. If you want to operate on the property whose name is in the name variable, then you use position[name], not position.name.
So, if you remove the quotes from the declaration of position or call JSON.parse() on it to make it into an object so it's this:
var position = {
"weather": {
"id": "weather",
"x": 0,
"y": 0,
"width": 12,
"height": 9
},
"google_calendar": {
"id": "google_calendar",
"x": 0,
"y": 10,
"width": 12,
"height": 9
},
"clock": {
"id": "clock",
"x": 0,
"y": 19,
"width": 3,
"height": 3
},
"todo": {
"id": "todo",
"x": 3,
"y": 19,
"width": 6,
"height": 4
}
};
Then, you can do this:
var name = 'clock';
delete position[name];
console.log(position);
And, that will end up deleting the clock property from your object.

var position = {
"weather": {
"id": "weather",
"x": 0,
"y": 0,
"width": 12,
"height": 9
},
"google_calendar": {
"id": "google_calendar",
"x": 0,
"y": 10,
"width": 12,
"height": 9
},
"clock": {
"id": "clock",
"x": 0,
"y": 19,
"width": 3,
"height": 3
},
"todo": {
"id": "todo",
"x": 3,
"y": 19,
"width": 6,
"height": 4
}
};
Below statement will do your job.
delete position["clock"]

Browsing a complex JSON

first of all, excuse me for my English, I'm French.
I am coming to you because I have a problem. I would like help browsing a complex JSON object with a loop in Javascript (because it generates itself with JOINTJS) but I am not being able to do it. I can do it manually by json [ "cells"] ["7"] ["attrs"] ["text"] ["text"]. Here is an example of JSON for one element:
{"cells":[
{
"type":"basic.Image",
"position":{
"x":50,
"y":350
},
"size":
{
"width":100,
"height":50
},
"angle":0,
"id":"4a2802a8-0bd6-4d06-9343-921092a1decd",
"z":1,
"attrs":{
"text":{
"text":"230004",
"fill":"black"
},
"image":{
"xlink:href":"/uploads/documents/computer.png",
"width":100,
"height":50
}
}
}
]}
and parse JSON :
I would get the "text": "230004" (which changes depending on the item).
Thank you in advance for your help !

You can access the object like this: obj.cells[7].attrs.text.text, where obj is a variable holding the object.
Also note that as the cells property holds an array, you can loop through that array and get each individual value separately, like this:
var obj = {
"cells": [{
"type": "basic.Image",
"position": {
"x": 50,
"y": 350
},
"size": {
"width": 100,
"height": 50
},
"angle": 0,
"id": "4a2802a8-0bd6-4d06-9343-921092a1decd",
"z": 1,
"attrs": {
"text": {
"text": "230004",
"fill": "black"
},
"image": {
"xlink:href": "/uploads/documents/computer.png",
"width": 100,
"height": 50
}
}
}, {
"type": "basic.Image",
"position": {
"x": 50,
"y": 350
},
"size": {
"width": 100,
"height": 50
},
"angle": 0,
"id": "4a2802a8-0bd6-4d06-9343-921092a1decd",
"z": 1,
"attrs": {
"text": {
"text": "230005",
"fill": "black"
},
"image": {
"xlink:href": "/uploads/documents/computer.png",
"width": 100,
"height": 50
}
}
}, {
"type": "basic.Image",
"position": {
"x": 50,
"y": 350
},
"size": {
"width": 100,
"height": 50
},
"angle": 0,
"id": "4a2802a8-0bd6-4d06-9343-921092a1decd",
"z": 1,
"attrs": {
"text": {
"text": "230006",
"fill": "black"
},
"image": {
"xlink:href": "/uploads/documents/computer.png",
"width": 100,
"height": 50
}
}
}]
}
obj.cells.forEach(function(cell) {
console.log(cell.attrs.text.text);
});
