Can't Connect To MongoDB Atlas Cluster

Issue type:

[ ] question [X] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [X] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [ ] postgres [ ] sqlite [ ] sqljs [ ] react-native [ ] expo

TypeORM version:

[X] latest [ ] @next [ ] 0.x.x (or put your version here)

Steps to reproduce or a small repository showing the problem:

I have a valid connection string to a Mongo Atlas DB that I am trying to use with TypeORM. I know the connection string works because I have used it from Python and from the Mongo shell. But it doesn’t work from typeorm. I have tried both the mongodb:// and mongo+srv synax. Not sure how to debug or figure this one out. Here is the error:

(node:19257) DeprecationWarning: current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.
{ MongoNetworkError: connection 5 to cluster0-XXXX.mongodb.net:27017 closed

After few tries I have two valid configurations for typeorm and mongo atlas:

const connection = await createConnection({
            type: "mongodb",
            useNewUrlParser: true,
            url: "mongodb://admin:[e-mail]:27017,testcluster0-shard-00-01-1cmyo.mongodb.net:27017,testcluster0-shard-00-02-1cmyo.mongodb.net:27017/test?ssl=true&replicaSet=TestCluster0-shard-0&authSource=admin&retryWrites=true",
            ssl: true,
            authSource: "admin",
            replicaSet: "TestCluster0-shard-0"
        });

and second one

const connection = await createConnection({
            type: "mongodb",
            url: "mongodb+srv://admin:[e-mail]/test?retryWrites=true",
            ssl: true,
            authSource: "admin",
            replicaSet: "TestCluster0-shard-0"
        });

But I think @pointtoken is right. Calling mongodb connect method with undefined option properties overwrites settings from url.

So the below worked for me. I am using Nestjs

{
  "type": "mongodb",
  "url": "mongodb+srv://<user>:<password>@cluster0.somethingsomething.mongodb.net/<dbname>?retryWrites=true&w=majority",
  "useNewUrlParser": true,
  "synchronize": true,
  "logging": true,
  "useUnifiedTopology": true,
  "entities": ["dist/**/*.entity{.ts,.js}"]
}
