### Create HTTP Server and Routes

Source: https://context7.com/ltick/tick-framework/llms.txt

Sets up an HTTP server with a custom router, defining routes for various HTTP methods, enabling metrics and pprof, and configuring a reverse proxy. Ensure necessary imports for http, access, and cors are available.

```go
package main

import (
    "time"
    ltick "github.com/ltick/tick-framework"
    "github.com/ltick/tick-framework/api"
    "github.com/ltick/tick-routing/cors"
)

func main() {
    registry, _ := ltick.NewRegistry()
    engine := ltick.New(registry)

    // Create a router with options
    router := engine.NewServerRouter(
        ltick.ServerRouterRequestTimeout("30s"),
        ltick.ServerRouterAccessLogFunc(customAccessLog),
        ltick.ServerRouterCors(&cors.Options{
            AllowOrigins: "*",
            AllowHeaders: "*",
            AllowMethods: "GET,POST,PUT,DELETE",
        }),
    )

    // Create server with configuration
    server := engine.NewServer(router,
        ltick.ServerPort(8080),
        ltick.ServerGracefulStopTimeoutDuration(30*time.Second),
        ltick.ServerReadTimeoutDuration(10*time.Second),
        ltick.ServerWriteTimeoutDuration(30*time.Second),
    )

    // Define routes with host-based routing
    server.Get([]string{"*"}, "/api/v1", "/users/<id>", &GetUserHandler{})
    server.Post([]string{"*"}, "/api/v1", "/users", &CreateUserHandler{})
    server.Put([]string{"*"}, "/api/v1", "/users/<id>", &UpdateUserHandler{})
    server.Delete([]string{"*"}, "/api/v1", "/users/<id>", &DeleteUserHandler{})

    // Enable metrics and pprof endpoints
    server.Metrics([]string{"*"}, "/metrics", nil)
    server.Pprof([]string{"*"}, nil)

    // Setup reverse proxy
    server.Proxy([]string{"*"}, "/proxy", "/*", "http://backend:8081/<:path>")

    // Register server with engine
    engine.RegisterServer("main", server)

    engine.Startup()
    engine.ListenAndServe()
}

func customAccessLog(req *http.Request, res *access.LogResponseWriter, elapsed float64) {
    log.Printf("%s %s %d %.3fms", req.Method, req.URL.Path, res.Status, elapsed)
}
```

### Initialize TICK Engine

Source: https://context7.com/ltick/tick-framework/llms.txt

Demonstrates how to initialize the TICK Engine with custom configuration sources, built-in components, and lifecycle callbacks. Ensure configuration files and .env files exist.

```go
package main

import (
    ltick "github.com/ltick/tick-framework"
)

func main() {
    // Create a new registry for components
    registry, err := ltick.NewRegistry()
    if err != nil {
        panic(err)
    }

    // Use built-in components
    registry.UseComponent("Log", "Database", "Kvstore", "Queue")

    // Create engine with configuration options
    engine := ltick.New(registry,
        ltick.EngineConfigFile("./config/app.json"),
        ltick.EngineConfigDotenvFile("./.env"),
        ltick.EngineConfigEnvPrefix("MYAPP"),
        ltick.EngineCallback(&AppCallback{}),
    )

    // Startup the engine (initializes all components)
    if err := engine.Startup(); err != nil {
        panic(err)
    }

    // Start listening for HTTP requests
    engine.ListenAndServe()
}

// AppCallback implements lifecycle hooks
type AppCallback struct{}

func (c *AppCallback) OnStartup(e *ltick.Engine) error {
    // Initialize application-specific resources
    return nil
}

func (c *AppCallback) OnShutdown(e *ltick.Engine) error {
    // Clean up resources
    return nil
}
```

--------------------------------

### Register Components and Configure Dependency Injection

Source: https://context7.com/ltick/tick-framework/llms.txt

Register custom components with the registry and use the inject tag to automatically populate struct fields with dependencies.

```go
package main

import (
    "context"
    ltick "github.com/ltick/tick-framework"
    "github.com/ltick/tick-framework/database"
    "github.com/ltick/tick-framework/kvstore"
)

// UserService component with injected dependencies
type UserService struct {
    Database *database.Database `inject:"true"`
    Kvstore  *kvstore.Kvstore   `inject:"true"`
}

func (s *UserService) Prepare(ctx context.Context) (context.Context, error) {
    return ctx, nil
}

func (s *UserService) Initiate(ctx context.Context) (context.Context, error) {
    // Initialize service-specific resources
    return ctx, nil
}

func (s *UserService) OnStartup(ctx context.Context) (context.Context, error) {
    // Called when engine starts
    return ctx, nil
}

func (s *UserService) OnShutdown(ctx context.Context) (context.Context, error) {
    // Clean up on shutdown
    return ctx, nil
}

func main() {
    registry, _ := ltick.NewRegistry()

    // Use built-in components
    registry.UseComponent("Database", "Kvstore")

    // Register custom component
    registry.RegisterComponent(&ltick.Component{
        Name:          "UserService",
        Component:     &UserService{},
        ConfigurePath: "components.userService",
    }, false)

    // Register values for injection
    registry.RegisterValue("AppName", "MyApplication")

    engine := ltick.New(registry)
    engine.Startup()
}
```

--------------------------------

### Kafka Producer and Consumer Operations

Source: https://context7.com/ltick/tick-framework/llms.txt

Demonstrates producing and consuming JSON messages using Kafka with the Tick Framework's queue component. Ensure Kafka handler and producer/consumer configurations are correctly set up.

```go
package main

import (
    "context"
    "github.com/ltick/tick-framework/queue"
    "encoding/json"
)

type OrderEvent struct {
    OrderID   string `json:"order_id"`
    UserID    string `json:"user_id"`
    Amount    float64 `json:"amount"`
    Timestamp int64  `json:"timestamp"`
}

func kafkaOperations(q *queue.Queue) {
    ctx := context.Background()

    // Get Kafka handler
    handler, err := q.GetKafkaHandler("default")
    if err != nil {
        panic(err)
    }

    // Create a producer
    producer, err := handler.NewProducer(ctx, "orders", func(ctx context.Context, topic, msg string, err error) {
        log.Printf("Producer error: topic=%s, message=%s, error=%v", topic, msg, err)
    })
    if err != nil {
        panic(err)
    }

    // Produce messages
    event := OrderEvent{
        OrderID:   "ORD-12345",
        UserID:    "USER-001",
        Amount:    99.99,
        Timestamp: time.Now().Unix(),
    }

    data, _ := json.Marshal(event)
    producer.Produce(data)

    // Create a consumer group
    consumer, err := handler.NewConsumer(ctx, "order-processor", "orders")
    if err != nil {
        panic(err)
    }
    defer consumer.Close()

    // Consume messages
    for msg := range consumer.Messages() {
        var event OrderEvent
        if err := json.Unmarshal(msg.Value, &event); err != nil {
            log.Printf("Failed to unmarshal: %v", err)
            continue
        }

        // Process the event
        processOrder(event)

        // Mark message as processed
        consumer.MarkOffset(msg)
    }
}

func processOrder(event OrderEvent) {
    log.Printf("Processing order: %s for user: %s", event.OrderID, event.UserID)
}

```

--------------------------------

### Implement Custom Middleware in Go

Source: https://context7.com/ltick/tick-framework/llms.txt

Define middleware by implementing the required interface methods. Use dependency injection tags to provide necessary services like KV stores or configuration.

```go
package middleware

import (
    "context"
    "github.com/ltick/tick-routing"
)

// AuthMiddleware implements MiddlewareInterface
type AuthMiddleware struct {
    // Dependencies can be injected
    SecretKey string `inject:"true"`
}

func (m *AuthMiddleware) Prepare(ctx context.Context) (context.Context, error) {
    return ctx, nil
}

func (m *AuthMiddleware) Initiate(ctx context.Context) (context.Context, error) {
    return ctx, nil
}

func (m *AuthMiddleware) OnRequestStartup(c *routing.Context) error {
    // Extract token from header
    token := c.Request.Header.Get("Authorization")
    if token == "" {
        c.Response.WriteHeader(401)
        c.Response.Write([]byte(`{"error": "Unauthorized"}`))
        c.Abort()
        return nil
    }

    // Validate token
    userID, err := validateToken(token, m.SecretKey)
    if err != nil {
        c.Response.WriteHeader(401)
        c.Response.Write([]byte(`{"error": "Invalid token"}`))
        c.Abort()
        return nil
    }

    // Store user info in context
    c.Set("user_id", userID)
    return nil
}

func (m *AuthMiddleware) OnRequestShutdown(c *routing.Context) error {
    // Cleanup after request
    return nil
}

// RateLimitMiddleware limits requests per client
type RateLimitMiddleware struct {
    Kvstore *kvstore.Kvstore `inject:"true"`
    Limit   int
    Window  int64 // seconds
}

func (m *RateLimitMiddleware) OnRequestStartup(c *routing.Context) error {
    clientIP := c.Request.RemoteAddr
    key := fmt.Sprintf("ratelimit:%s", clientIP)

    pool, _ := m.Kvstore.GetRedisHandler("default")
    count, _ := pool.Get(key)

    if count != nil && count.(int) >= m.Limit {
        c.Response.WriteHeader(429)
        c.Response.Write([]byte(`{"error": "Rate limit exceeded"}`))
        c.Abort()
        return nil
    }

    pool.Set(key, count.(int)+1)
    pool.Expire(key, m.Window)
    return nil
}
```

--------------------------------

### Manage User Sessions in Go

Source: https://context7.com/ltick/tick-framework/llms.txt

Utilize the API context to set, retrieve, and destroy session data. Ensure handlers are structured to handle authentication states.

```go
package handlers

import (
    "github.com/ltick/tick-framework/api"
)

type LoginHandler struct {
    Username string `param:"<in:formData> <name:username> <required>"`
    Password string `param:"<in:formData> <name:password> <required>"`
}

func (h *LoginHandler) Serve(ctx *api.Context) error {
    // Authenticate user
    user, err := authenticate(h.Username, h.Password)
    if err != nil {
        return ctx.Response.Write(api.NewResponseData("AccessDenied", nil))
    }

    // Store user in session
    ctx.SetSession("user_id", user.ID)
    ctx.SetSession("user_role", user.Role)

    return ctx.Response.Write(api.NewResponseData("Success", user))
}

type ProfileHandler struct{}

func (h *ProfileHandler) Serve(ctx *api.Context) error {
    // Get user from session
    userID := ctx.GetSession("user_id")
    if userID == nil {
        return ctx.Response.Write(api.NewResponseData("AccessDenied", nil))
    }

    user, _ := getUserByID(userID.(int64))
    return ctx.Response.Write(api.NewResponseData("Success", user))
}

type LogoutHandler struct{}

func (h *LogoutHandler) Serve(ctx *api.Context) error {
    // Destroy session
    ctx.DestroySession()
    return ctx.Response.Write(api.NewResponseData("Success", nil))
}
```

--------------------------------

### Application Configuration with Tick Framework

Source: https://context7.com/ltick/tick-framework/llms.txt

Configures the Tick Framework engine with custom options, including environment variable interpolation, default values, and hot-reloading. Access configuration values using type-specific getter methods.

```go
package main

import (
    ltick "github.com/ltick/tick-framework"
    "github.com/ltick/tick-framework/config"
)

func main() {
    registry, _ := ltick.NewRegistry()

    // Define custom configuration options
    customConfigs := map[string]config.Option{
        "API_KEY":        {Type: config.String, EnvironmentKey: "API_KEY"},
        "MAX_CONNECTIONS": {Type: config.Int, Default: 100, EnvironmentKey: "MAX_CONNECTIONS"},
        "ENABLE_CACHE":   {Type: config.Bool, Default: true, EnvironmentKey: "ENABLE_CACHE"},
        "TIMEOUT":        {Type: config.String, Default: "30s", EnvironmentKey: "TIMEOUT"},
    }

    engine := ltick.New(registry,
        ltick.EngineConfigFile("./config/app.json"),
        ltick.EngineConfigDotenvFile("./.env"),
        ltick.EngineConfigEnvPrefix("MYAPP"),
        ltick.EngineConfigConfigs(customConfigs),
    )

    // Access configuration values
    apiKey := engine.GetConfigString("API_KEY")
    maxConns := engine.GetConfigInt("MAX_CONNECTIONS")
    enableCache := engine.GetConfigBool("ENABLE_CACHE")
    timeout := engine.GetConfigDuration("TIMEOUT")

    // Access nested configuration
    dbHost := engine.GetConfigString("components.database.host")

    // Get configuration as map
    dbConfig := engine.GetConfigStringMap("components.database")

    engine.Startup()
}

```

--------------------------------

### Define API Handlers with Parameter Binding

Source: https://context7.com/ltick/tick-framework/llms.txt

Use struct tags to automatically bind path, query, header, JSON body, and multipart form data parameters to handler fields.

```go
package handlers

import (
    "github.com/ltick/tick-framework/api"
)

// GetUserHandler binds path, query, and header parameters automatically
type GetUserHandler struct {
    // Path parameter (required by default)
    ID int64 `param:"<in:path> <name:id> <required>"`

    // Query parameters
    Fields  string `param:"<in:query> <name:fields>"`
    Include string `param:"<in:query> <name:include>"`

    // Header parameters
    Authorization string `param:"<in:header> <name:Authorization> <required>"`
}

func (h *GetUserHandler) Serve(ctx *api.Context) error {
    // Parameters are automatically bound from the request
    user, err := getUserByID(h.ID)
    if err != nil {
        return ctx.Response.Write(api.NewResponseData("NotFound", nil))
    }

    return ctx.Response.Write(api.NewResponseData("Success", user))
}

// CreateUserHandler binds JSON body to struct
type CreateUserHandler struct {
    // Body parameter for JSON payload
    Body CreateUserRequest `param:"<in:body>"`
}

type CreateUserRequest struct {
    Name     string `json:"name"`
    Email    string `json:"email"`
    Password string `json:"password"`
}

func (h *CreateUserHandler) Serve(ctx *api.Context) error {
    // h.Body is automatically populated from JSON request body
    user, err := createUser(h.Body)
    if err != nil {
        return ctx.Response.Write(api.NewResponseData("BadRequest", nil, err.Error()))
    }

    ctx.Response.WriteHeader(201)
    return ctx.Response.Write(api.NewResponseData("Success", user))
}

// FormUploadHandler handles multipart form data with file uploads
type FormUploadHandler struct {
    File     *multipart.FileHeader   `param:"<in:formData> <name:file> <required> <maxmb:10>"`
    Files    []*multipart.FileHeader `param:"<in:formData> <name:files>"`
    Category string                   `param:"<in:formData> <name:category>"`
}

func (h *FormUploadHandler) Serve(ctx *api.Context) error {
    // Process uploaded file
    file, err := h.File.Open()
    if err != nil {
        return ctx.Response.Write(api.NewResponseData("BadRequest", nil))
    }
    defer file.Close()

    // Save file or process content
    return ctx.Response.Write(api.NewResponseData("Success", map[string]string{
        "filename": h.File.Filename,
        "size":     fmt.Sprintf("%d", h.File.Size),
    }))
}
```

--------------------------------

### Handle API Responses in Go

Source: https://context7.com/ltick/tick-framework/llms.txt

Register custom response codes globally and use the framework's response helper to return structured JSON data.

```go
package main

import (
    "github.com/ltick/tick-framework/api"
    "net/http"
)

func init() {
    // Register custom response codes
    api.RegisterResponseOption("ValidationError", http.StatusUnprocessableEntity, "Validation failed")
    api.RegisterResponseOption("DuplicateEntry", http.StatusConflict, "Resource already exists")
    api.RegisterResponseOption("PaymentRequired", http.StatusPaymentRequired, "Payment is required")
}

type CreateOrderHandler struct {
    Body OrderRequest `param:"<in:body>"`
}

func (h *CreateOrderHandler) Serve(ctx *api.Context) error {
    // Validate request
    if err := validate(h.Body); err != nil {
        return ctx.Response.Write(api.NewResponseData("ValidationError", nil, err.Error()))
    }

    // Check for duplicate
    if exists, _ := orderExists(h.Body.ID); exists {
        return ctx.Response.Write(api.NewResponseData("DuplicateEntry", nil))
    }

    // Create order
    order, err := createOrder(h.Body)
    if err != nil {
        return ctx.Response.Write(api.NewResponseData("InternalError", nil))
    }

    // Return success with data
    ctx.Response.WriteHeader(201)
    return ctx.Response.Write(api.NewResponseData("Success", order))
}
```

--------------------------------

### Perform MySQL Database Operations with GORM

Source: https://context7.com/ltick/tick-framework/llms.txt

Utilize the database component to handle migrations, CRUD operations, transactions, and raw SQL execution. Requires a configured MySQL handler from the framework's database module.

```go
package main

import (
    "github.com/ltick/tick-framework/database"
)

// User model
type User struct {
    ID        uint   `gorm:"primary_key"`
    Name      string `gorm:"size:255"`
    Email     string `gorm:"unique_index"`
    CreatedAt time.Time
    UpdatedAt time.Time
}

func databaseOperations(db *database.Database) {
    // Get MySQL handler
    handler, err := db.GetMysqlHandler("default")
    if err != nil {
        panic(err)
    }

    // Auto migrate tables
    handler.AutoMigrate(&User{})

    // Create record
    user := &User{Name: "John", Email: "john@example.com"}
    handler.Create(user)

    // Query records
    var users []User
    handler.Where("name LIKE ?", "%John%").
        Order("created_at DESC").
        Limit(10).
        Find(&users)

    // Find single record
    var singleUser User
    handler.First(&singleUser, "email = ?", "john@example.com")

    // Update record
    handler.Model(&singleUser).Updates(map[string]interface{}{
        "name": "John Doe",
    })

    // Transaction
    tx := handler.Begin()
    if err := tx.Create(&User{Name: "Jane"}).Error(); err != nil {
        tx.Rollback()
        return
    }
    tx.Commit()

    // Raw SQL
    var result []map[string]interface{}
    handler.Raw("SELECT * FROM users WHERE id > ?", 0).Scan(&result)

    // Execute SQL
    handler.Exec("UPDATE users SET status = ? WHERE id = ?", "active", 1)
}
```

--------------------------------

### Perform Redis Cache Operations

Source: https://context7.com/ltick/tick-framework/llms.txt

Manage Redis data structures including strings, hashes, sets, and sorted sets using the kvstore component. Includes support for connection pooling and cursor-based scanning for large datasets.

```go
package main

import (
    "github.com/ltick/tick-framework/kvstore"
)

func redisOperations(kv *kvstore.Kvstore) {
    // Get Redis handler
    pool, err := kv.GetRedisHandler("default")
    if err != nil {
        panic(err)
    }

    // String operations
    pool.Set("user:1:name", "John Doe")
    value, _ := pool.Get("user:1:name")

    // Set expiration
    pool.Set("session:abc123", "user_data")
    pool.Expire("session:abc123", 3600) // 1 hour

    // Check existence
    exists, _ := pool.Exists("user:1:name")

    // Delete key
    pool.Del("user:1:name")

    // Hash operations
    pool.Hset("user:1", "name", "John")
    pool.Hset("user:1", "email", "john@example.com")
    pool.Hmset("user:2", "name", "Jane", "email", "jane@example.com")

    name, _ := pool.Hget("user:1", "name")
    allFields, _ := pool.Hgetall("user:1")

    // Set operations
    pool.Sadd("tags:post:1", "golang", "framework", "web")
    count, _ := pool.Scard("tags:post:1")

    // Sorted set operations
    pool.Zadd("leaderboard", 100, "player1", 200, "player2", 150, "player3")
    topPlayers, _ := pool.Zrevrange("leaderboard", 0, 9)
    score, _ := pool.Zscore("leaderboard", "player1")

    // Scan operations for large datasets
    cursor := "0"
    for {
        nextCursor, keys, _ := pool.Scan(cursor, "user:*", 100)
        for _, key := range keys {
            // Process each key
        }
        if nextCursor == "0" {
            break
        }
        cursor = nextCursor
    }
}
```
