The following example shows how to delete a document using the name"Foo Bar" from the collection of peoplethe database teston localhostit uses of the API: Remove()

// 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{})

MongoDB officially supports golang. Here is an example of removing 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
