### 1.2 Core Features
1. Confession submission
2. Image generation from confessions
3. Moderation system
4. Gallery of approved confessions
5. Reply system for confessions

### 1.3 Technical Requirements

}

type User struct {
    ID       string `json:"id" surreal:"id"`

    Password string `json:"-"` // Password hash, not exposed in JSON
    IsAdmin  bool   `json:"isAdmin"`
}
```

## 4. Database Setup

### 4.1 SurrealDB Installation
Follow the official SurrealDB documentation to install and set up SurrealDB on your system.

### 4.2 Database Connection
Create `internal/database/surrealdb.go`:

```go
package database

import (
    "github.com/surrealdb/surrealdb.go"
    "github.com/yourusername/confession-image-generator/internal/models"
)

type SurrealDBClient struct {
    DB *surrealdb.DB
}

func Connect(connectionString string) (*SurrealDBClient, error) {
    db, err := surrealdb.New(connectionString)
    if err != nil {
        return nil, err
    }
    return &SurrealDBClient{DB: db}, nil
}

// Implement CRUD operations for Confession, Reply, and User
func (c *SurrealDBClient) CreateConfession(confession *models.Confession) error {
    // Implementation
}

func (c *SurrealDBClient) GetConfession(id string) (*models.Confession, error) {
    // Implementation

    // Implementation
}

// Implement similar functions for Reply and User
```

## 5. Image Generation Module

Create `internal/image/generator.go`:

```go
package image

}

func GenerateImage(confession *models.Confession, config ImageConfig) ([]byte, error) {
    dc := gg.NewContext(config.Width, config.Height)
    
    // Draw background gradient
    drawGradient(dc, config)
    
    // Add day number
    addDayNumber(dc, confession.DayNumber, config)
    
    // Add confession text
    addConfessionText(dc, confession.Content, config)
    
    // If there's a reply, add it
    if len(confession.Replies) > 0 {
        addReplyText(dc, confession.Replies[0].Content, config)
    }
    
    // Convert to PNG
    return dc.EncodePNG()
}

func drawGradient(dc *gg.Context, config ImageConfig) {
    // Implementation
}

func addDayNumber(dc *gg.Context, dayNumber int, config ImageConfig) {
    // Implementation
}

func addConfessionText(dc *gg.Context, text string, config ImageConfig) {
    // Implementation
}

func addReplyText(dc *gg.Context, text string, config ImageConfig) {
    // Implementation
}
```

## 6. API Development

### 6.1 API Handlers
Create `internal/api/handlers.go`:

```go

```go
package api

import "github.com/gin-gonic/gin"

func AuthMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {
        // Implement authentication logic
    }
}

func AdminMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {
        // Implement admin authentication logic
    }
}
```

## 7. Frontend Development

### 7.1 HTML Templates
Create the following files in `web/templates/`:

1. `index.html`: Main page with confession submission form
2. `gallery.html`: Gallery of approved confessions
3. `admin.html`: Admin interface for moderation

### 7.2 Static Assets
1. Create `web/static/css/styles.css` for styling
2. Create `web/static/js/main.js` for frontend interactivity

## 8. Main Application

Create `cmd/server/main.go`:

```go
package main

import (
    "github.com/gin-gonic/gin"
    "github.com/yourusername/confession-image-generator/internal/api"
    "github.com/yourusername/confession-image-generator/internal/database"
    "github.com/yourusername/confession-image-generator/internal/image"
    "github.com/yourusername/confession-image-generator/internal/config"
)

func main() {
    // Load configuration
    cfg := config.Load()

    // Initialize database
    db, err := database.Connect(cfg.DatabaseURL)
    if err != nil {
        // Handle error
    }

    // Set up Gin router
    router := gin.Default()

    // Load HTML templates
    router.LoadHTMLGlob("web/templates/*")

    // Serve static files
    router.Static("/static", "./web/static")

    // Initialize handler
    handler := &api.Handler{
        DB: db,
        ImageConfig: cfg.ImageConfig,
    }

    // Set up routes
    router.GET("/", handler.Home)
    router.GET("/gallery", handler.Gallery)
    router.POST("/confessions", handler.SubmitConfession)
    router.GET("/confessions/:id", handler.GetConfession)
    router.POST("/confessions/:id/replies", handler.SubmitReply)
    router.POST("/login", handler.Login)
    router.POST("/logout", handler.Logout)

    // Admin routes
    admin := router.Group("/admin", api.AdminMiddleware())
    {
        admin.GET("/", handler.AdminDashboard)
        admin.POST("/confessions/:id/moderate", handler.ModerateConfession)
    }

    // Start server
    router.Run(cfg.ServerAddress)
}
```

## 9. Configuration

Create `internal/config/config.go`:

```go
package config

import (
    "github.com/yourusername/confession-image-generator/internal/image"
)

type Config struct {
    DatabaseURL   string
    ServerAddress string
    ImageConfig   image.ImageConfig
}

func Load() *Config {
    // Load configuration from environment variables or config file
    // Return populated Config struct
}
```

## 10. Testing

### 10.1 Unit Tests
Create test files for each package, e.g., `internal/database/surrealdb_test.go`, `internal/image/generator_test.go`, etc.

### 10.2 Integration Tests
Create `internal/api/handlers_test.go` for testing API endpoints.

### 10.3 End-to-End Tests
Create a separate package for end-to-end tests that simulate user interactions.

## 11. Deployment

### 11.1 Dockerfile
Create a `Dockerfile` in the root directory for containerizing the application.

### 11.2 Docker Compose
Create a `docker-compose.yml` file for easy local deployment and testing.

### 11.3 CI/CD Pipeline
Set up a CI/CD pipeline using GitHub Actions or GitLab CI.

## 12. Documentation

### 12.1 README.md
Update the `README.md` file with:
- Project overview
- Setup instructions
- Usage guide
- API documentation
- Contributing guidelines

### 12.2 Code Comments
Add comprehensive comments to all functions and types across the project.

### 12.3 API Documentation
Use a tool like Swagger to generate API documentation.

## 13. Security Considerations

- Implement proper input validation and sanitization
- Use HTTPS for all communications
- Implement rate limiting to prevent abuse
- Securely store and handle user passwords (use bcrypt for hashing)
- Implement CSRF protection
- Use secure sessions for user authentication

## 14. Monitoring and Logging

- Implement structured logging throughout the application
- Set up monitoring using tools like Prometheus and Grafana
- Implement error tracking (e.g., using Sentry)

## 15. Scaling Considerations

- Implement caching for frequently accessed data (e.g., using Redis)
- Design the system to be horizontally scalable
- Consider using a message queue for handling image generation asynchronously

## 16. Maintenance

- Set up automated backups for the database
- Implement a system for easy database migrations
- Create a process for regular security audits and dependency updates

This comprehensive plan covers all aspects of the project, from initial setup to ongoing maintenance. It provides a step-by-step guide for implementing each component of the system, ensuring that all elements are properly defined before they're referenced. A developer following this plan should have all the information needed to build the confession image generator application in Go.
