[charlieroth]

Issue type:

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

Database system/driver:

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

TypeORM version:

[ ] latest
[ ] @next
[x] 0.2.9 (or put your version here)

package.json:

{
   "name": "...",
   "version": "...",
   "description": "...",
   "devDependencies": {
      "ts-node": "7.0.1",
      "@types/node": "^10.12.9",
      "typescript": "3.1.6"
   },
   "dependencies": {
      "@types/dotenv": "^6.1.0",
      "dotenv": "^6.1.0",
      "mongodb": "^3.1.10",
      "reflect-metadata": "^0.1.10",
      "tslint": "^5.11.0",
      "typeorm": "0.2.9"
   },
   "scripts": {
      "start": "..."
   }
}

Steps to reproduce or a small repository showing the problem:

import * as dotenv from "dotenv";
import "reflect-metadata";
import { createConnection } from "typeorm";

dotenv.config();
createConnection({
    cli: {
        entitiesDir: "src/entity",
        migrationsDir: "src/migration",
        subscribersDir: "src/subscriber",
    },
    entities: [
        "src/entity/**/*.ts",
    ],
    logging: true,
    migrations: [
        "src/migration/**/*.ts",
    ],
    subscribers: [
        "src/subscriber/**/*.ts",
    ],
    synchronize: true,
    type: "mongodb",
    url: `mongodb+srv://${process.env.MONGODB_ATLAS_USERNAME}:${process.env.MONGODB_ATLAS_PASSWORD}@inquisitive-cluster-1-j18op.mongodb.net/inquisitive-db?retryWrites=true`,
}).then(async (connection) => {
    console.log("Connection succesful");
    console.log("Connection: ", connection);
}).catch((error) => {
    console.log("Connection failed");
    console.log(error);
});

When I run npm start I get the following error:

(node:3634) 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.

I see older issues with a similar problem and was wondering if an update in the MongoDB node driver is causing this or if this is due to my configuration settings?

I've never used MongoDB Atlas Cluster before, but I think you need to include useNewUrlParser: true in your createConnection options.

import * as dotenv from "dotenv";
import "reflect-metadata";
import { createConnection } from "typeorm";

dotenv.config();
createConnection({
    cli: {
        entitiesDir: "src/entity",
        migrationsDir: "src/migration",
        subscribersDir: "src/subscriber",
    },
    entities: [
        "src/entity/**/*.ts",
    ],
    logging: true,
    migrations: [
        "src/migration/**/*.ts",
    ],
    subscribers: [
        "src/subscriber/**/*.ts",
    ],
    synchronize: true,
    useNewUrlParser: true
    type: "mongodb",
    url: `mongodb+srv://${process.env.MONGODB_ATLAS_USERNAME}:${process.env.MONGODB_ATLAS_PASSWORD}@inquisitive-cluster-1-j18op.mongodb.net/inquisitive-db?retryWrites=true`,
}).then(async (connection) => {
    console.log("Connection succesful");
    console.log("Connection: ", connection);
}).catch((error) => {
    console.log("Connection failed");
    console.log(error);
});

I'm seeing this as well. But the issue for me isn't just getting a warning; I can't connect via typeorm to a mongodb atlas cluster at all. What are the tricks for getting typeorm to connect to a mongodb atlas cluster? (Works fine against a local mongodb instance)

@charlieroth if this issue is only about warning please, please see this comment #2650 (comment).

If there is problem with connect to mongo atlas please check this answer #3347 (comment)

Let me know if this help.

This issue should be fixed by #3366 and will be in next release. Feel free reopen if problem persists.
