Joining only matching elements - node.js

I want to join more than two collections in MongoDB . Is it possible to join?
I have 2 collections and I want to join them based by their ids
news collection
{
"lang": "ru",
"news": [{
"title": "title",
"content": "desc",
"image": "path",
"categoryId": {
"$oid": "6171499e0ba3d75082823c9a"
},
"createdAt": {
"$date": "2021-10-21T12:30:33.215Z"
},
"_id": {
"$oid": "61715d7990905adefcf314d1"
}
}]
}
and I have got newscategory collection like that
[
{
"lang": "ru",
"categories": [{
"name": "sdfsdsdcsdf",
"_id": {
"$oid": "6171499e0ba3d75082823c9a"
}
}]
},
{
"lang": "en",
"categories": [{
"name": "ooo",
"_id": {
"$oid": "61712980f8ee795c6a569dcb"
}
}, {
"name": "yuy",
"_id": {
"$oid": "61712980f8ee795c6a569dcc"
}
}, {
"name": "rtyrty",
"_id": {
"$oid": "61712980f8ee795c6a569dcd"
}
}]
}
]
Expected Output:
[
{
"_id": "61715d7990905adefcf314d0",
"lang": "ru",
"news": [
{
"title": "sdf",
"content": "sdf",
"image": "asdas",
"categoryId": "6171499e0ba3d75082823c9a",
"caregory": [
{
"name": "sdfsdsdcsdf",
"_id": "6171499e0ba3d75082823c9a"
},
]
"createdAt": "2021-10-21T12:30:33.215Z",
"_id": "61715d7990905adefcf314d1"
}
],
Match is based on both "category_id" and "categories._id".
How can I achieve result like that ?

How to set up aggregation pipeline for specific use case in MongoDB

`I have two collections in MongoDB. One is users and the other is companies. I need to be able to populate the users.endpoints with the endpoints from companies that match ObjectID's which are in the user.endPoints property. It is a bit hard for me to wrap my head around considering there are two steps.
This is the companies collection.

This is the users collection.

"endpoints": [
// I need to populate to endpoints here!!!! //
"c80bd1ab-ca8d-4649-9d35-56d64ef8fab5"

}
I can do a single step aggregation, but this is a little complicated for me.`

My background is php/mysql. I understand the basics here just can't put it together. Any help would be greatly appreciated.
Thanks
I have the basics of the typescript started to grab all the appropriate documents. I don't know how to go about combining some of the data and updating it back to mongo
Here is the basic code I am starting with
makeScript({
module,
db: true,
init: async _argv => {
await Pv2.find({
attributes: {
$elemMatch: {
type: 'allergens'
},
},
})
.limit(10)
.cursor()
.eachAsync(async (oldPv2s: Pv2Doc | Pv2Doc[]) => {
// not sure what goes here
});
}
});

Aggregation query

Node js using mongoose as ORM. I have set of documents like below
I want to calculate the average time for createdAt in ISO String(format) field in duration of hours on
grouping the category field. I have tried many ways to use aggregate but couldn't get the result.

const foundUser= await User.find({"user":req.body.user},("Orders") ).exec()

You can use an aggregation pipeline with a $filter for this:
db.collection.aggregate([
{
$match: {
"user": "jon"
}
},
{
$project: {
ORDERS: {
$filter: {
input: "$ORDERS",
as: "item",
cond: {$ne: ["$$item.Trackingnumber", 0]}
}
}
}
}
])
Playground example

User.find({"Orders" : {"Trackingnumber": 0} })

Mongodb apply condition on $lookup fetched data

I am having data from two different collections on which I am applying $lookup with $match which is working fine. What I am trying to do is on lookup's result I am applying $match again which is having some conditions. Here is the collection of User on which I am applying lookup.
Users collection :-
{
"_id": {
"$oid": "5b714631faaae220d7cc07cf"
},
"name": "abc",
"surname": "xyz",
"email": "abc#gmail.com",
"hotel_data": [
{
"location": {
"type": "Point",
"coordinates": [
30.7052881,
76.84470799999997
]
},
"_id": {
"$oid": "5b7fb8559849fd485dc47240"
},
"status": true,
"activityname": "Sparrow",
},
{
"location": {
"type": "Point",
"coordinates": [
30.733315,
76.779419
]
},
"_id": {
"$oid": "5b7f9ecb9960053dac7ce6f1"
},
"status": true,
"activityname": "Raj Hotel",
},
]
}
and this is my availabilities collection on which I am applying $lookup with $match.
{
"_id": {
"$oid": "5b867766d63c4e2cdd5534d2"
},
"businessid": {
"$oid": "5b7fb8559849fd485dc47240"
},
"userid": {
"$oid": "5b714631faaae220d7cc07cf"
},
"hotel_filters": [
{
"_id": {
"$oid": "5b867766d63c4e2cdd5534d3"
},
"hotelservice": [
{
"service_id": "5b472fff25556c3f02a875aa",
"service_name": "Pool",
"_id": {
"$oid": "5b867767d63c4e2cdd5534d7"
}
},
{
"service_id": "5b472fdb25556c3f02a875a9",
"service_name": "AIR",
"_id": {
"$oid": "5b867767d63c4e2cdd5534d8"
}
}
],
"location_type": [
{
"locationtype_id": "5b18f4d08c63f42019763b12",
"locationtype_name": "Scenic View",
"_id": {
"$oid": "5b867767d63c4e2cdd5534d5"
}
},
{
"locationtype_id": "5b18f4e38c63f42019763b13",
"locationtype_name": "Central",
"_id": {
"$oid": "5b867767d63c4e2cdd5534d6"
}
}
],
"hotel_type": [
{
"hoteltype_id": "5b081452edefe23318834a28",
"hoteltype_name": "3 Star",
"_id": {
"$oid": "5b867767d63c4e2cdd5534d4"
}
}
]
}
]
}
and what I am trying to do is- after $lookup I only want those availabilities data which are having "hotelservice.service_id" and "location_type.locationtype_id" that I will pass. And I have tried this by applying this query to it(In this query I have only applied "hotelservice.service_id" but later on I also want to apply query with $and on "location_type.locationtype_id").
User.aggregate([
{
$match:{
"hotel_data.location": {
"$geoWithin": {
"$centerSphere": [
[30.7052881, 76.84470799999997], 50/ 6371
]
}
}
}
},{
"$unwind": "$hotel_data"
},
{
$match:{
"hotel_data.location": {
"$geoWithin": {
"$centerSphere": [
[30.7052881, 76.84470799999997], 50/ 6371
]
}
}
}
},
{
$lookup: {
from: "availabilities",
localField: "hotel_data._id",
foreignField: "businessid",
as: "availabilitiesdata"
}
},
{$match:{$and: [{"availabilitiesdata.hotel_filters.hotelservice.service_id":{$in:[5b472fb725556c3f02a875a8]}}]}}
], function(err, data) {
if (err) {
return res.send({data: err, status: false, msg:"No Hotel Found" });
}else{
return res.send({status: true, msg:"Hotel Found", data:data });
}
});
This query gives me result as follow.

I want only those availabilities which match the condition on my $lookup availability data. can someone help me out.

You can use $lookup pipeline variant to apply the $match inside the joined collection in 3.6
Something like ( replace $lookup & $match stage with below lookup pipeline )
{"$lookup":{
"from":"availabilities",
"let":{"hotel_data_id":"$hotel_data._id"},
"pipeline":[
{"$match":{
"hotel_filters.hotelservice.service_id":{"$in":["5b472fb725556c3f02a875a8"]},
"hotel_filters.location_type.locationtype_id":{"$in":["5b18f4798c63f42019763b11"]},
"$expr":{"$eq":["$$hotel_data_id","$businessid"]}
}}
],
"as":"availabilitiesdata"
}}
