I have idea for support multiple collection.

[renogies]

class MongoConnection {
private env: any;

constructor(env: any) {
    this.env = env;
}
// Generic method to return a collection of a specific type
collection<T>(): MongoDBAPI<T> {
    return new MongoDBAPI<T>(this.env);
}

}

---

// Create a MongoConnection instance
const connection = new MongoConnection(env);

// Get the collections
const taskCollection = connection.collection();
const taskItemCollection = connection.collection();

const task = await taskCollection.findOne({ status: { $eq: "complete" } });
console.log("Found task:", task);

const taskItem = await taskItemCollection.findOne({ status: { $eq: "complete" } });
console.log("Found taskItem :", taskItem );
