[@types/mongodb] Property 'isConnected' does not exist on type 'Server'

[fabiooshiro]

Hi @rifler

• [x] I tried using the @types/mongodb package and had problems.

import { MongoClient, Db } from "mongodb";
let db: Db = /*async getDb... */
db.serverConfig.isConnected()

error TS2339: Property 'isConnected' does not exist on type 'Server | ReplSet | Mongos'.
  Property 'isConnected' does not exist on type 'Server'.

You think I broke it in https://github.com/DefinitelyTyped/DefinitelyTyped/pull/43279 ?

@fabiooshiro which version of driver api you're using?

[fabiooshiro]

Hi, the version is "@types/mongodb": "^3.5.3",

I'm seeing the same with client.isConnected()

Property 'isConnected' does not exist on type 'Mongo'.

I'll try to be on the same page, I believe MongoClient.isConnected({}?) method works OK, with current types and driver 3.6,

const client = new MongoClient('mongodb://localhost:27017', {
  useUnifiedTopology: true,
});
(async () => {
    await client.connect()
    if (client.isConnected()) {
        await client.close();
    }
})();

The server fires events, including 'connected', has no direct API on the surface to check connection status IMO: http://mongodb.github.io/node-mongodb-native/3.6/api/Server.html#event:connect (I could be wrong on this, never had to write a code to check the server status that way, client is enough)
