GoVisual Multi-Storage Example

This example demonstrates how to use GoVisual with different storage backends:

• In-memory storage (default)
• PostgreSQL
• Redis

Running the Example

You can run the example using Docker Compose, which will set up all necessary services:

# Start all services
docker-compose up -d

# View logs
docker-compose logs -f

By default, the application will use in-memory storage. You can change the storage backend by modifying the environment variables in docker-compose.yml:

Using In-Memory Storage (Default)

environment:
  - PORT=8080
  # No additional environment variables needed for in-memory storage

Using PostgreSQL Storage

environment:
  - PORT=8080
  - GOVISUAL_STORAGE_TYPE=postgres
  - GOVISUAL_PG_CONN=postgres://postgres:postgres@postgres:5432/govisual?sslmode=disable
  - GOVISUAL_PG_TABLE=govisual_requests

Using Redis Storage

environment:
  - PORT=8080
  - GOVISUAL_STORAGE_TYPE=redis
  - GOVISUAL_REDIS_CONN=redis://redis:6379/0
  - GOVISUAL_REDIS_TTL=86400

Using SQLite Storage

environment:
  - PORT=8080
  - GOVISUAL_STORAGE_TYPE=sqlite
  - GOVISUAL_SQLITE_DBPATH=/data/govisual.db
  - GOVISUAL_SQLITE_TABLE=govisual_requests

Using MongoDB Storage

GOVISUAL_STORAGE_TYPE=mongodb
GOVISUAL_MONGO_URI=mongodb://root:root@localhost:27017/
GOVISUAL_MONGO_DATABASE=logs
GOVISUAL_MONGO_COLLECTION=request_logs

Accessing the Application

Once the application is running, you can access it at:

• Main application: http://localhost:8080
• GoVisual dashboard: http://localhost:8080/__viz

Available Endpoints

• GET /: Home page with instructions
• GET /api/users: List users (JSON)
• POST /api/users: Create user (expects JSON body)
• GET /api/products: List products (JSON)
• POST /api/products: Create product (expects JSON body)

Running Without Docker

If you prefer to run the example without Docker, you can use:

# In-memory storage (default)
go run main.go

# PostgreSQL storage
GOVISUAL_STORAGE_TYPE=postgres \
GOVISUAL_PG_CONN="postgres://postgres:postgres@localhost:5432/govisual?sslmode=disable" \
go run main.go

# Redis storage
GOVISUAL_STORAGE_TYPE=redis \
GOVISUAL_REDIS_CONN="redis://localhost:6379/0" \
go run main.go
