example usage:
import { MongoClient } from "mongodb";
import BaseDao from "mongodb-dao-es6";
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: 
MongoClientfrom themongodbpackage andBaseDaofrom themongodb-dao-es6package. - Connection Setup:  It establishes a connection to your MongoDB database using the provided connection string (
uri). - Configuration:  The 
configobject defines the database name, collection name, sorting criteria, and page size for pagination. - BaseDao Instance:  A new instance of the 
BaseDaoclass is created, using the provided configuration and the established client. - CRUD Operations: The code demonstrates the following CRUD operations:
- Create:  The 
createmethod is used to insert a new document into the collection. - Find:  The 
findmethod retrieves documents from the collection. - Update:  The 
updatemethod modifies an existing document. - Delete:  The 
deletemethod removes a document from the collection. 
 - Create:  The 
 - Error Handling:  A 
try...catchblock handles potential errors during the database operations. - Connection Closure:  The 
finallyblock 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-es6package installed in your project. You can install it usingnpm install mongodb-dao-es6.
