get installed mongodb version from mongoose

[aakrem]

After taking a look on the links below it seems that the solution is outdated.
node-mongodb-native is not available even in package.json
So anyone has a solution to get the installed mongodb version from mongoose ?

The solutions aren't outdated. node-mongodb-native isn't in the package.json because node-mongodb-native is the github repo name, the npm package is mongodb.

Here's what mongoose uses internally to determine the version of the mongodb instance its talking to.

  mongoose.connection.on('open', function() {
    var admin = mongoose.connection.db.admin();
    admin.serverStatus(function(err, info) {
      if (err) return cb(err);
      var version = info.version.split('.').map(function(n) { return parseInt(n, 10); });
      cb(null, version);
    });
  });

@aakrem You can also use serverInfo() which has a version string property.

console.log((await mongoose.connection.db.admin().serverInfo()).version);
