URL Shortener Application

Local Development Setup

Prerequisites

• Go 1.25 or later
• Redis (local installation)

Installation

1. Install Redis locally:

   # macOS
   brew install redis
   
   # Start Redis
   brew services start redis
   # OR
   redis-server

2. Install Go dependencies:

   go mod download

3. Set up environment variables: Edit .env if needed (defaults should work for local Redis):

   • APP_PORT: Port for the API server (default: 8080)
   • DB_ADDR: Redis address (default: localhost:6379)
   • DB_PASS: Redis password (leave empty for local Redis without password)

4. Run the application:

   go run .

   The API will be available at http://localhost:8080
