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

## Use hot reload

Hot reload mode can be enabled while creating applications in Go. The hot reload reloads the application if changes occur in the source code. To enable hot reload, we install a library called  air with the following command (this command is available in Go version 1.16 or above):

```sh
go install github.com/cosmtrek/air@latest
```

Check the installation with the following command:

```sh
air -v
```

Initialize the hot reload configuration with the following command:
```sh
air init
```

We create the hot reload configuration file i in the `.air.toml` file. To run the application with a hot reload mechanism, we use the `air` command.

```sh
air
```

The hot reload is enabled in the application. We try to make changes in the source code, then save it. If the changes are detected, the application will be reloaded.
