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

# Introduction

This application is created with the Go programming language and with some additional libraries. The libraries that are used in this project are:

- gqlgen: Used for creating a server with its handler.
- UUID: Used for creating an ID for data or records inside the storage.

# Initialize the project

You may use the following commands to initialize the project if you have to set it up on a local machine. However, it has already been set up for you on the Educative platform.


```sh
go mod init domain_name/username/project_name
```

This is an example of initializing the project command.

```sh
go mod init github.com/nadirbasalamah/go-gql-blogs
```

After the project is initialized, install the following libraries.


```sh
go get github.com/99designs/gqlgen@v0.17.10
```

```sh
go get github.com/google/uuid
```

# Initialize the application

Initialize the GraphQL application with this command.

```sh
go run github.com/99designs/gqlgen init
```

# Define the schema

The `schema.graphqls` contains the schema definition for the GraphQL application that contains the default schema for the application. We define the schema for the blog application in that file.


Learn how to set up the GraphQL application.
