async function main() {
  const uri = "your_mongodb_connection_string";
  const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

  try {
    await client.connect();
    const config = {
      dbName: "your_database_name",
      collection: "your_collection_name",
      sort: { _id: -1 },
      pageSize: 10,
    };

    const baseDao = new BaseDao(config, client);

    // Create a new document
    const newData = { name: "John Doe", age: 30 };
    const createdData = await baseDao.create(newData);
    console.log("Created Data:", createdData);

    // Find documents
    const foundData = await baseDao.find();
    console.log("Found Data:", foundData);
		
    // Find documents
		baseDao.match = { name: "John Doe", age: 30 };
    const foundData = await baseDao.find();
    console.log("Found Data:", foundData);

    // Update a document
    baseDao.id = createdData[0]._id;
    const updatedData = await baseDao.update({ age: 31 });
    console.log("Updated Data:", updatedData);

    // Delete a document
    const deletedData = await baseDao.delete();
    console.log("Deleted Data:", deletedData);

  } catch (err) {
    console.error(err);
  } finally {
    await client.close();
  }
}

main().catch(console.error);

Explanation:

• Import Statements: The code imports the necessary modules: MongoClient from the mongodb package and BaseDao from the mongodb-dao-es6 package.
• Connection Setup: It establishes a connection to your MongoDB database using the provided connection string (uri).
• Configuration: The config object defines the database name, collection name, sorting criteria, and page size for pagination.
• BaseDao Instance: A new instance of the BaseDao class is created, using the provided configuration and the established client.
• CRUD Operations: The code demonstrates the following CRUD operations:
  • Create: The create method is used to insert a new document into the collection.
  • Find: The find method retrieves documents from the collection.
  • Update: The update method modifies an existing document.
  • Delete: The delete method removes a document from the collection.
• Error Handling: A try...catch block handles potential errors during the database operations.
• Connection Closure: The finally block ensures that the database connection is closed properly, even if an error occurs.

Important Notes:

• Replace Placeholders: Remember to replace "your_mongodb_connection_string", "your_database_name", and "your_collection_name" with your actual MongoDB connection details.
• Package Installation: Make sure you have the mongodb-dao-es6 package installed in your project. You can install it using npm install mongodb-dao-es6.
