AI Explanation

This Go program establishes a connection to a MongoDB database using the official MongoDB Go driver. Here's a breakdown of the code: 1. The program imports necessary packages including context, fmt, log, time, and the MongoDB driver packages. 2. In the `main()` function: - It creates a new MongoDB client using `mongo.NewClient()` with options specifying the connection URI. This URI includes a username, password, and address of the MongoDB server. - If there's an error in creating the client, it logs the error and exits. - It then initializes a context with a timeout of 10 seconds. - The program attempts to connect to the MongoDB server using the client's `Connect()` method with the timeout context. If an error occurs during the connection, it logs the error and exits. - If the connection is successful, it prints "Successfully connected to MongoDB!". - Finally, it defers disconnecting the client using `Disconnect()` method with the context. 3. The connection URI in `ApplyURI()` function should be modified to include the actual username, password, and the correct address of the MongoDB server. 4. The program demonstrates connecting to a MongoDB database in Go, handling errors, and ensuring proper disconnection from the database after the operation. Overall, this code snippet demonstrates a basic connection setup to MongoDB using Go.
