In modern backend applications, many programming languages can be chosen, including Go—a programming language that provides high performance with concise syntax and can also be used to develop backend applications, including REST API and GraphQL applications. This course will cover many tools that can be used to develop a backend application, including fiber for REST API application, gqlgen for GraphQL application, and apitest for testing purposes.

In this course, you’ll learn about the main concepts of web applications, including HTTP, REST API, databases, and GraphQL. You’ll cover how to develop a backend application and deploy the application as well. 

By the end of the course, you’ll be able to develop a backend application using REST API and GraphQL approach. Also, you’ll be able to test and deploy the backend application that has been developed.

Building a Backend Application with Go

# Add CRUD functionality to the service component

In the previous lesson, the service component uses local storage with a slice in Go. Because persistent storage will be used, we change the local storage to persistent storage using the MySQL database for all functionalities.
## Get all items

Inside the `services.go` file, we change the implementation of the function used for getting all items.

func GetAllItems() []models.Item {
	// create a variable to store items data
	var items []models.Item = []models.Item{}

	// get all data from the database order by created_at
	database.DB.Order("created_at desc").Find(&items)

	// return all items from the database
	return items
}


routes/routes.go

In the code above, the variable called `items` is created to store the item data from the database. The `Find()` method is used to get all the data from the database. All data or records from the database are stored in the `items` variable, then this variable is returned.

## Get item by ID

Inside the `services.go` file, we change the implementation for getting items by ID.
