# Go Backend Clean Architecture
A Go (Golang) Backend Clean Architecture project with Gin, MongoDB, JWT Authentication Middleware, Test, and Docker.
**You can use this project as a template to build your Backend project in the Go language on top of this project.**
Before creating this project, I have gone through more than 20 projects related to the Go(Golang) Clean Architecture on GitHub.
Thanks to all those projects, I learned a lot from all of those. As I keep saying:
> The best way to learn to code is to code. But, to write good code, you will also have to read good code. Make a habit of reading good code. You can find many open-source projects on GitHub and start reading.
Then for the implementation part, I combined all of my ideas, experiences, and learnings from those projects to create this project.
And as always I would love to get feedback on my project. This helps everyone and most importantly me.
Learn about this project architecture in detail from the blogs mentioned below:
- [Go Backend Clean Architecture](https://amitshekhar.me/blog/go-backend-clean-architecture)
- [Go JWT Authentication Middleware](https://amitshekhar.me/blog/go-jwt-authentication-middleware)
- [Configuration with Viper in Go](https://amitshekhar.me/blog/configuration-with-viper-in-go)
- [Test with Testify and Mockery in Go](https://amitshekhar.me/blog/test-with-testify-and-mockery-in-go)
## Architecture Layers of the project

## About me
Hi, I am [**Amit Shekhar**](https://amitshekhar.me), I have mentored many developers, and their efforts landed them high-paying tech jobs, helped many tech companies in solving their unique problems, and created many open-source libraries being used by top companies. I am passionate about sharing knowledge through open-source, blogs, and videos.

## Major Packages used in this project
- **gin**: Gin is an HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need a smashing performance, get yourself some Gin.
- **mongo go driver**: The Official Golang driver for MongoDB.
- **jwt**: JSON Web Tokens are an open, industry-standard RFC 7519 method for representing claims securely between two parties. Used for Access Token and Refresh Token.
- **viper**: For loading configuration from the `.env` file. Go configuration with fangs. Find, load, and unmarshal a configuration file in JSON, TOML, YAML, HCL, INI, envfile, or Java properties formats.
- **bcrypt**: Package bcrypt implements Provos and Mazières's bcrypt adaptive hashing algorithm.
- **testify**: A toolkit with common assertions and mocks that plays nicely with the standard library.
- **mockery**: A mock code autogenerator for Golang used in testing.
- Check more packages in `go.mod`.

### How to run this project?
We can run this Go Backend Clean Architecture project with or without Docker. Here, I am providing both ways to run this project.
- Clone this project
```bash
# Move to your workspace
cd your-workspace
# Clone this project into your workspace
git clone https://github.com/amitshekhariitbhu/go-backend-clean-architecture.git
# Move to the project root directory
cd go-backend-clean-architecture
```
#### Run without Docker
- Create a file `.env` similar to `.env.example` at the root directory with your configuration.
- Install `go` if not installed on your machine.
- Install `MongoDB` if not installed on your machine.
- Important: Change the `DB_HOST` to `localhost` (`DB_HOST=localhost`) in `.env` configuration file. `DB_HOST=mongodb` is needed only when you run with Docker.
- Run `go run cmd/main.go`.
- Access API using `http://localhost:8080`
#### Run with Docker
- Create a file `.env` similar to `.env.example` at the root directory with your configuration.
- Install Docker and Docker Compose.
- Run `docker-compose up -d`.
- Access API using `http://localhost:8080`
### How to run the test?
```bash
# Run all tests
go test ./...
```
### How to generate the mock code?
In this project, to test, we need to generate mock code for the use-case, repository, and database.
```bash
# Generate mock code for the usecase and repository
mockery --dir=domain --output=domain/mocks --outpkg=mocks --all
# Generate mock code for the database
mockery --dir=mongo --output=mongo/mocks --outpkg=mocks --all
```
Whenever you make changes in the interfaces of these use-cases, repositories, or databases, you need to run the corresponding command to regenerate the mock code for testing.
