I am building a nextjs ecommerce and after adding mongoose and trying to connect to mongodb local server from api route, it throws:

 ⨯ src\utils\mongoHelper.ts (7:31) @ mongoDBUri
 ⨯ (0 , mongoose__WEBPACK_IMPORTED_MODULE_1__.createConnection) is not a function
   5 |
   6 | let mongoConnect = async () => {
>  7 |  let client = createConnection(mongoDBUri);

my code:

import Product from "@/models/product";
import mongoose, { connect, connection, createConnection } from "mongoose";

const mongoDBUri = process.env.DB_URI as string;

let mongoConnect = async () => {
    let client = createConnection(mongoDBUri);

    if (client.readyState == 1) {
        return;
    }

    await connect(mongoDBUri);
};

export default mongoConnect;

turns out exporting a runtime config from api route that handles the mongo connection and retrive/post data breaks mongoose

// export const config = {
//     runtime: "edge",
// };

Hi @<Milind ツ /> , if you are still encountering with this problem, I can help you.
import mongoose from "mongoose";

const connect = async() => {
    try {
        await mongoose.connect(process.env.DATABASE_URL!, {
            dbName:"<YOUR DB NAME>",
            authSource:"admin"
        });
        console.log("MongoDB connection successfully established")
    } catch(err){
                throw new Error("Error occured while connecting mongodb");
    }
}

export default connect;
you can use this approach too.
don't forget to remove dbName and authSource from your database URL
DATABASE_URL="mongodb+srv://admin:password@<cluster_name>.89234234.mongodb.net/"

Removing the edge runtime config from api route did the trick for me back then. Now I switched to prisma so not an issue anymore
I forgot to mark this answered hmm
