mongo remove all dbs

To remove all databases in MongoDB using the Go programming language, you can follow these steps:

1. Import the necessary packages:

import (
    "context"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

1. Establish a connection to the MongoDB server:

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

1. Access the admin database:

adminDB := client.Database("admin")

1. List all databases:

databases, err := adminDB.ListDatabases(context.Background(), bson.M{})
if err != nil {
    // Handle error
}

1. Iterate over the list of databases and drop each one:

for _, db := range databases.Databases {
    err := client.Database(db.Name).Drop(context.Background())
    if err != nil {
        // Handle error
    }
}

This code first connects to the MongoDB server using the provided URI. It then accesses the admin database and retrieves a list of all databases. Finally, it iterates over the list and drops each database using the Drop function.
