currently i am finding today data . also need to find current week data and current month data.

exports.getData = function(req,res)
{
getMyData().then(function(data){
res.status(200).json({
msg:'true',
data: data
});
}).catch(function(err){
res.status(401).json({
msg:'Not Logged In',
error: err
});
});
function getMyData(){
return new Promise(function(resolve,reject){
var token = req.headers['x-access-token'];
if (!token)
return reject({'msg':'No Token'});
jwt.verify(token,config.secret,function(err,decode){
if(err)
{
reject({'msg':'Failed to authenticate token.'});
}
else{
var start = new Date();
start.setHours(0,0,0,0);
var end = new Date();
end.setHours(23,59,59,999);
Data.find({userId: decode.id,created: {$gte: start, $lt: end}},function(err,data){
if(err){
reject(err);
}
else
{
resolve(data);
}
});
}
});
});
}
}
here is my schema
var DataSchema = new Schema({
userId: {
type: String,
required: 'Kindly enter your Report'
},data: {
type: String,
required: 'Kindly enter your Report'
},
created:{
type:Date,
default:Date.now
}
});

You can call find query based on different conditions from node.js.
async function getMyData() {
var token = req.headers['x-access-token'];
if (!token)
throw {
'msg': 'No Token'
};
jwt.verify(token, config.secret, function (err, decode) {
if (err) {
throw err;
} else {
let today = new Date();
today.setHours(0, 0, 0, 0)
let first = today.getDate() - today.getDay();
let last = first + 6;
let firstday = new Date(today.setDate(first)).toUTCString();
let lastday = new Date(today.setDate(last)).toUTCString();
let firstDayMonth = new Date(today.setDate(1));
let lastDayMonth = new Date(today.getFullYear(), today.getMonth() + 1, 0)
lastDayMonth.setHours(23, 59, 59, 0);
today = new Date().setHours(0, 0, 0, 0);
return await Promise.all([
Data.find({
userId: decode.id,
created: {
$gte: today
}
}).exec(),
Data.find({
userId: decode.id,
created: {
$gte: firstday,
$lte: lastday
}
}).exec(),
Data.find({
userId: decode.id,
created: {
$gte: firstDayMonth,
$lte: lastDayMonth
}
}).exec()
]);
}
});
}
MongoDB Aggregate query : only problem I'm seeing is $cond else block returns "". That you can handle in node js.
var today = new Date().setHours(0, 0, 0, 0);
var first = today.getDate() - today.getDay();
var firstDayWeek = new Date(today.setDate(first));
var lastDayWeek = new Date(today.setDate(first + 6));
var firstDayMonth = new Date(today.setDate(1));
var lastDayMonth = new Date(today.getFullYear(), today.getMonth() + 1, 0)
lastDayWeek.setHours(23, 59, 59, 0);
lastDayMonth.setHours(23, 59, 59, 0);
today = new Date().setHours(0, 0, 0, 0);
db.getCollection('TEST').aggregate([{
$match: {
userId: decode.id
}
}, {
$group: {
"_id": "",
"today": {
$push: {
$cond: {
if: {
$gte: ["$created", new Date(today)]
},
then: "$$ROOT",
else: ''
}
}
},
"week": {
$push: {
$cond: [{
$and: [{
$gte: ["$created", new Date(firstDayWeek)]
},
{
$lte: ["$created", new Date(lastDayWeek)]
}
]
},
"$$ROOT",
''
]
}
},
"month": {
$push: {
$cond: [{
$and: [{
$gte: ["$created", new Date(firstDayMonth)]
},
{
$lte: ["$created", new Date(lastDayMonth)]
}
]
},
"$$ROOT",
''
]
}
}
}
}])
//If you want to filter in mongo query
.forEach(function (data) {
data.today = data.today.filter(e => e != "")
data.week = data.week.filter(e => e != "")
print(data);
})
Output
{
"_id": "",
"today": [{
"_id": ObjectId("5aaa2605d52a86d42a362479"),
"created": ISODate("2018-03-15T07:51:33.014Z")
}
