Mongoose Type Error

This is my mongodb connection code

await mongoose.connect("mongodb://127.0.0.1:27017", {
  autoIndex: false,
  retryWrites: true,
})

await mongoose.connect("mongodb://127.0.0.1:27017", {
  autoIndex: false,
  retryWrites: true,
})

But the problem is Deno showing this error:

Argument of type '{ autoIndex: false; retryWrites: true; }' is not assignable to parameter of type 'ConnectOptions'.
  Type '{ autoIndex: false; retryWrites: true; }' is missing the following properties from type 'ConnectOptions': family, hints, localAddress, localPort, lookupdeno-ts(2345)
(property) ConnectOptions.autoIndex?: boolean | undefined
Set to false to disable automatic index creation for all models associated with this connection.

What's the problem? In node we can modify the mongoose connection options but what's the problem here? In our team we heavily relay on Mongoose and Redis and Kafka, Stripe, NodeMailer. I'm trying to implement our back-end now on Deno. Can anyone ensure me that all those packages will work properly with deno? In previous I've tried to do this but face a lot's of problem. But this time I am trying again.

I apologize, but I wasn't able to find the answer to your question in the official Deno documentation. However, based on the error message you've provided, it seems that the options object you're passing to mongoose.connect may not be matching the expected ConnectOptions type that the function expects. Please note that Mongoose is a library that is traditionally used with Node.js, and Deno does not support Node.js modules out of the box due to differences in the runtime environments. Deno uses a different set of APIs and module system (ES Modules), and it does not have built-in support for npm packages without some form of compatibility layer or porting effort. Regarding the other packages you mentioned (Redis, Kafka, Stripe, NodeMailer), you would need to find Deno-compatible versions or alternatives, as the Node.js versions of these packages will not work directly in Deno. For example, Deno has its own set of modules for interacting with Redis, and there are third-party modules available for other services, but they may not have the same API as the Node.js versions you're used to. The advice provided here is not based on the Deno documentation, and I recommend double-checking the accuracy of this advice and looking for Deno-specific modules or libraries that can provide the functionality you need. For MongoDB, you might want to look into Deno's native database drivers or modules that are designed to work with Deno. For further assistance, you may want to explore the Deno third-party module registry (https://deno.land/x) or reach out to the community for modules that are compatible with Deno for the services you are using.

Fixed Using This:

async databaseConnection() {
    const options: Partial<ConnectOptions> = {
      autoIndex: false,
      retryWrites: true,
      dbName: "YOUR_DB_NAME",
      connectTimeoutMS: 12000,
    }

    await mongoose
      .connect(Deno.env.get("MONGODB_URL") || "", options as ConnectOptions)
      .then(() => console.log("Database Connected... 🔌⚡✅"))
  }

async databaseConnection() {
    const options: Partial<ConnectOptions> = {
      autoIndex: false,
      retryWrites: true,
      dbName: "YOUR_DB_NAME",
      connectTimeoutMS: 12000,
    }

    await mongoose
      .connect(Deno.env.get("MONGODB_URL") || "", options as ConnectOptions)
      .then(() => console.log("Database Connected... 🔌⚡✅"))
  }

This no longer works even with @types/mongoose 😦
