import { MongoClient } from "https://deno.land/x/[email protected]/mod.ts";
import { env } from "../config.ts";

const client = new MongoClient();

// Connecting to a Mongo Atlas Database
await client.connect({
  db: "dip",
  tls: true,
  servers: [
    {
      host: env.MONGO_HOSTNAME,
      port: 27017,

  credential: {
    username: env.MONGO_USER_NAME,
    password: env.MONGO_USER_PASSWORD,
