How to use go mongo to connect to a MongoDB instance?
To connect to a MongoDB instance using the go mongo driver, follow these steps:go mongo driver, follow these steps:

1. Install the go mongo driver:

   <code class="bash">go get go.mongodb.org/mongo-driver</code>

   Copy after login

2. Import the mongo-driver package into your Go program:

   <code class="go">import (
    "context"
    "fmt"
    "go.mongodb.org/mongo-driver/mongo"
   )</code>

   Copy after login

3. Create a mongo.Client object to establish a connection to the MongoDB instance:

   <code class="go">client, err := mongo.Connect(context.Background(), options.Client().ApplyURI("mongodb://localhost:27017"))
   if err != nil {
    // Handle error.
   }
   defer client.Disconnect(context.Background())</code>

   Copy after login

What are the benefits of using go mongo for MongoDB interactions?
Using go mongo for MongoDB interactions offers several benefits:

• Efficient and Type-Safe: go mongo provides type-safe wrappers for MongoDB operations, ensuring data integrity and reducing errors.
• Concurrency Support: It handles concurrent requests effectively, allowing multiple operations to run simultaneously.
• Rich Feature Set: Supports a comprehensive range of MongoDB features, including querying, aggregation, and indexing.
• API Compatibility: Provides a consistent API across MongoDB versions, simplifying code maintenance and migration.
• Extensibility: Offers hooks and interfaces for customizing functionality and creating reusable components.

How can I perform CRUD operations using go mongo?
go mongo supports the following CRUD (Create, Read, Update, Delete) operations for MongoDB:
Create: func (c *Collection) InsertOne(ctx context.Context, document interface{}, opts ...InsertOneOptions) (*InsertOneResult, error)
Read: func (c *Collection) Find(ctx context.Context, filter interface{}, opts ...FindOptions) (*Cursor, error)
Update:

Update One: func (c *Collection) UpdateOne(ctx context.Context, filter interface{}, update interface{}, opts ...UpdateOptions) (*UpdateResult, error)
Update All: func (c *Collection) UpdateMany(ctx context.Context, filter interface{}, update interface{}, opts ...UpdateOptions) (*UpdateResult, error)
Delete: func (c *Collection) DeleteOne(ctx context.Context, filter interface{}, opts ...DeleteOptions) (*DeleteResult, error)
Delete Many: func (c *Collection) DeleteMany(ctx context.Context, filter interface{}, opts ...DeleteOptions) (*DeleteResult, error)
Example of Create

<code class="go">// Create a document in the "users" collection.
result, err := coll.InsertOne(ctx, bson.D{{"name", "John Doe"}})
if err != nil {
    // Handle error.
}

fmt.Println("Inserted a single document: ", result.InsertedID)</code>
