MongoDB - sort by words - mongodb

Question

Having data like below.
{
"summary": "testing api1",
"UpdatedDate": {
"$date": "2018-12-30T00:00:00.000Z"
},
"status": "draft"
},
{
"summary": "testing api2",
"UpdatedDate": {
"$date": "2018-12-30T00:00:00.000Z"
},
"status": "published"
},
{
"summary": "testing api3",
"UpdatedDate": {
"$date": "2018-12-30T00:00:00.000Z"
},
"status": "delete"
}
I want to sort based "status"
For ex: If I have given sort by status "published" then I need data like below
{
"summary": "testing api2",
"UpdatedDate": {
"$date": "2018-12-31T00:00:00.000Z"
},
"status": "published"
},
{
"summary": "testing api1",
"UpdatedDate": {
"$date": "2018-12-30T00:00:00.000Z"
},
"status": "draft"
},
{
"summary": "testing api3",
"UpdatedDate": {
"$date": "2019-01-01T00:00:00.000Z"
},
"status": "delete"
}
It's possible in mongodb? or anything available similar like this?

Ideally, you would assign a numerical value. But you can do it just as you have it with Aggregation framework.
Something like this with $addFields and $cond:
db.getCollection("yourcollection").aggregate([
{
$addFields: {
sortNum: {
$cond: [
{ $eq: ["$status", "published"] },
0,
{ $cond: [{ $eq: ["$status", "draft"] }, 1, 2] }
]
}
}
},
{
$sort: {
sortNum: 1
}
}
]);
OR With $switch
db.collection.aggregate([{
$addFields: {
sortNum: {
$switch: {
branches: [
{
case: {
$eq: ["$status", "published"]
},
then: 1
},
{
case: {
$eq: ["$status", "delete"]
},
then: 2
},
{
case: {
$eq: ["$status", "draft"]
},
then: 3
}
],
default: 0
}
}
}
},
{
$sort: {
sortNum: 1
}
}]);
