Mongoose Aggregate with $match on date range or local time zone - node.js

Question

I have invoice Model as following
{
...
"itemDetails": [
{
"item": "593a1a01bbb00000043d9a4c",
"purchasingPrice": 100,
"sellingPrice": 150,
"qty": 200,
"_id": "59c39c2a5149560004173a05",
"discount": 0
}
],
"payments": [],
"status": "PENDING",
"created": {
"$date": "2017-09-21T11:02:02.675Z"
},
...
}
Sample Invoice Document is as follows.
{
"_id": {
"$oid": "59c39c2a5149560004173a04"
},
"customer": {
"$oid": "5935013832f9fc0004fa9a16"
},
"order": {
"$oid": "59c1df8393cbba0004a0e956"
},
"employee": {
"$oid": "592d0a6238880f0004637e84"
},
"status": "PENDING",
"deliveryStatus": "PROCESSING",
"created": {
"$date": "2017-09-21T11:02:02.675Z"
},
"discount": 0,
"payments": [],
"itemDetails": [
{
"item": {
"$oid": "593a1a01bbb00000043d9a4c"
},
"purchasingPrice": 100,
"sellingPrice": 150,
"qty": 200,
"_id": {
"$oid": "59c39c2a5149560004173a05"
},
"discount": 0
}
],
"__v": 0
}
Item details Item is an object Id which refers to Item collection.
I'm writing a mongoose Aggregate query to get the sale by Item. for that I need to filter the invoice from a given date range and status does not equal to "CANCELED". for that, I have written following code
module.exports.saleByItem = (req, res) => {
let fromDate;
let toDate;
if ((req.query.fromDate && moment(req.query.fromDate, config.dateFormat, true).isValid()) && (req.query.toDate && moment(req.query.toDate, config.dateFormat, true).isValid())) {
fromDate = moment(req.query.fromDate, config.dateFormat).startOf('day');
toDate = moment(req.query.toDate, config.dateFormat).endOf('day');
}
Invoice.aggregate([
{
"$match": {
"created": {
"$gte": fromDate
? fromDate.toDate()
: undefined,
"$lte": toDate
? toDate.toDate()
: undefined
},
"status": {
"$ne": "CANCELED"
}
}
}, {
"$unwind": "$itemDetails"
}, {
"$group": {
"_id": "$itemDetails.item",
"qty": {
"$sum": "$itemDetails.qty"
},
"value": {
"$sum": {
"$multiply": [
"$itemDetails.qty", {
"$subtract": ["$itemDetails.sellingPrice", "$itemDetails.discount"]
}
]
}
},
"avarageSellingPrice": {
"$avg": {
"$subtract": ["$itemDetails.sellingPrice", "$itemDetails.discount"]
}
}
}
}, {
"$sort": {
"value": -1
}
}, {
"$lookup": {
from: "items",
localField: "_id",
foreignField: "_id",
as: "item"
}
}, {
"$unwind": "$item"
}, {
"$project": {
_id: 1,
itemName: "$item.itemName",
qty: 1,
value: 1,
avarageSellingPrice: 1
}
}
]).then(salesFigures => {
res.status(200).json(salesFigures);
}).catch((err) => {
res.status(422).json(err);
});
};
The issue is when I put today date to both dates it returns sale of today. Gives []
How to handle date ranges in $match with local time-zone?
