Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. Although the package provides access to low-level networking primitives.

Package net/http provides HTTP client and server implementations.

1. Create a new project with Fiber:

cgapp create # Choose a backend framework: # > net/http # fiber # chi

2. Rename .env.example to .env and fill it with your environment values.

3. Install Docker and the following useful Go tools to your system:

   • golang-migrate/migrate for apply migrations
   • github.com/swaggo/swag for auto-generating Swagger API docs
   • github.com/securego/gosec for checking Go security issues
   • github.com/go-critic/go-critic for checking Go the best practice issues
   • github.com/golangci/golangci-lint for checking Go linter issues

4. Run project by this command:

make docker.run

5. Go to API Docs page (Swagger): 127.0.0.1:5000/swagger/index.html

Folder with business logic only. This directory doesn't care about what database driver you're using or which caching solution your choose or any third-party things.

• ./app/controllers folder for functional controllers (used in routes)
• ./app/models folder for describe business models and methods of your project
• ./app/queries folder for describe queries for models of your project
• ./app/validators folder for describe validators for models fields

Folder with API Documentation. This directory contains config files for auto-generated API Docs by Swagger.

Folder with project-specific functionality. This directory contains all the project-specific code tailored only for your business use case, like configs, middleware, routes or utils.

• ./pkg/configs folder for configuration functions
• ./pkg/middleware folder for add middleware (Fiber built-in and yours)
• ./pkg/routes folder for describe routes of your project
• ./pkg/utils folder with utility functions (server starter, error checker, etc)

Folder with platform-level logic. This directory contains all the platform-level logic that will build up the actual project, like setting up the database or cache server instance and storing migrations.

• ./platform/database folder with database setup functions (by default, PostgreSQL)
• ./platform/migrations folder with migration files (used with golang-migrate/migrate tool)
