How to get the data between two dates | NodsJs | MongoDB - node.js

Question

I am trying to create an api to get the data between two dates in NodeJS. My database is mongoDB, my data looks like this
_id:ObjectId("60ff19125474fa0ec45c2d1a")
username:"abc"
Date:"2021-7-26"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
_id:ObjectId("6101f4a4676d8b2b743a2d58")
username:"abc"
Date:"2021-7-27"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
_id:ObjectId("6102e1357ad1ed20d4642db0")
username:"abc"
Date:"2021-7-28"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
_id:ObjectId("6104717cb025c025e8b2d15e")
username:"abc"
Date:"2021-8-01"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
i want to fetch the data between two dates, i create an api to fetch data by date (single), need some modification to fetch it between two dates.
here is api to fetch data by date:
fetchHistorybydate =(req,res)=>{
var HistoryList = []
User.find({"username":req.body.username, "leave":{ $exists : false} },function(err,data){
for(var i =1 ;i<data.length;i++){
var NDate = data[i].Date;
if(NDate==req.body.date){
HistoryList.push(data[i])
}
}
if(err)
{res.status(300).json("Error")}
else{
var token = jwt.sign({
data: 'foobar'
}, 'secret', { expiresIn: "30 minute"})
res.status(200).json({AccessToken: token,data:HistoryList})
}
})
}
for example:
let say there are two calender on frontend one is for Fromdate and second is for Todate, if user select date from Fromdate calender this 2021-7-26 and from Todate calender this 2021-7-28 then it will only fetch the records from these dates.
the output should be, according to above data
_id:ObjectId("60ff19125474fa0ec45c2d1a")
username:"abc"
Date:"2021-7-26"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
_id:ObjectId("6101f4a4676d8b2b743a2d58")
username:"abc"
Date:"2021-7-27"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
_id:ObjectId("6102e1357ad1ed20d4642db0")
username:"abc"
Date:"2021-7-28"
TimeIn:"2:02 PM"
TimeOut:"2:02 PM"
Please help me how to do this.

You have to update the store Date object in the Date parameter of your database. After that, you'll be able to query by two date ranges. Currently, your Date parameter is a string, but, you have to convert it to a Date object.
Here is the solution after converting into Date object:
fetchHistorybydate = (req, res) => {
var query = {
username: req.body.username,
Date: {
$gte: new Date(req.body.Fromdate).toISOString(),
$lte: new Date(req.body.Todate).toISOString()
},
leave: { $exists: false }
}
User.find(query, function (err, data) {
if (err) { return res.status(300).json("Error") }
else {
return res.status(200).json({ data: data })
}
})
}
Note: No need to loop through the entire array again after retrieving the data. Because we already query from our database with the $gte and $lte parameters. Where $gte means greater than or equal and $lte means less than or equal.
You can also use $gt (greater than) and $lt (less than).
