MongoDB: How to find the exact version of installed MongoDB
MongodbMongodb Problem Overview
I have mongoDB 3.2 installed locally for Windows 7. I would like to find out its specific version (like is it 3.2.1, or 3.2.3 or...). How could I find it? If I open the database shell (mongo.exe), I can see it outputs:
> MongoDB shell version: 3.2.0
But that's just the shell version, and I'm not sure whether it's the same as my real database version.

Solution 6 - Mongodb
Sometimes you need to see version of mongodb after making a connection from your project/application/code. In this case you can follow like this:
mongoose.connect(
encodeURI(DB_URL), {
keepAlive: true
},
(err) => {
if (err) {
console.log(err)
}else{
const con = new mongoose.mongo.Admin(mongoose.connection.db)
con.buildInfo( (err, db) => {
if(err){
throw err
}
// see the db version
console.log(db.version)
})
}
}
)
Hope this will be helpful for someone.
