A simple and experimental URL shortening service written in Go

Shorter is a lightweight web service that allows you to shorten long URLs using a minimal web interface.
The project was created as an experimental implementation of a URL shortener with support for multiple databases and Redis caching.

• ✅ Shorten URLs via a web interface
• ✅ Cache popular links using Redis
• ✅ Support for two databases: PostgreSQL or MySQL (selected via build tags)
• ✅ Authentication using JWT

• Go (Golang) — primary programming language
• Redis — caching of URLs
• PostgreSQL / MySQL — data storage (chosen at build time)
• JWT — API protection
• HTML/JS — minimal frontend UI

1. Clone the repository:

   git clone https://github.com/tamper000/shorter.git
   cd shorter

2. Install dependencies:

   go get ./...

3. Create a config file:

   cp config.example.yaml config.yaml

4. Open config.yaml and adjust settings to match your environment:

   • Database settings (MySQL or PostgreSQL)
   • Redis configuration
   • Server and JWT settings

5. Run the app:

   go run cmd/main.go

6. Open in browser:

   http://localhost:8080
   

To run tests:

go test ./...

Example config: config.example.yaml.
The project uses a YAML-based configuration file where you can set:

• MySQL or PostgreSQL settings
• Redis parameters
• JWT configuration
• Server port
