How to remove a single document from MongoDB using Go

The following example demonstrates how to delete a single document with the name "Foo Bar" from a people collection in test database on localhost, it uses the Remove() method from the API:

// Get session
session, err := mgo.Dial("localhost")
if err != nil {
    fmt.Printf("dial fail %v\n", err)
    os.Exit(1)
}
defer session.Close()

// Error check on every access
session.SetSafe(&mgo.Safe{})

// Get collection
collection := session.DB("test").C("people")

// Delete record
err = collection.Remove(bson.M{"name": "Foo Bar"})
if err != nil {
    fmt.Printf("remove fail %v\n", err)
    os.Exit(1)
}

MongoDB officially supports golang. Here is a demostration of deleting an item from MongoDB:

// Assuming you've setup your mongoDB client
collection := client.Database("database_name").Collection("collection_hero")

deleteResult, _ := collection.DeleteOne(context.TODO(), bson.M{"_id": 
primitive.ObjectIDFromHex("_id")})
if deleteResult.DeletedCount == 0 {
    log.Fatal("Error on deleting one Hero", err)
}
return deleteResult.DeletedCount
