## 📦 **Installation**
```bash
go get github.com/SeaSBee/go-cachex
```
## 🚀 **Quick Start**
### Basic Usage
```go
package main
import (
"context"
"fmt"
"time"
"github.com/SeaSBee/go-cachex"
)
func main() {
// Create Redis configuration
config := &cachex.RedisConfig{
Addr: "localhost:6379",
Password: "",
DB: 0,
PoolSize: 10,
}
// Create Redis client
client, err := cachex.CreateRedisClient(config)
if err != nil {
panic(err)
}
defer client.Close()
// Create Redis cache with JSON codec
cache := cachex.NewRedisCache(client, nil, nil, nil)
defer cache.Close()
// Create typed cache for User
typedCache := cachex.NewTypedCache[User](cache)
ctx := context.Background()
user := User{ID: 1, Name: "John Doe", Email: "john@example.com"}
// Set a value
result := <-typedCache.Set(ctx, "user:1", user, 10*time.Minute)
if result.Error != nil {
panic(result.Error)
}
// Get a value
result = <-typedCache.Get(ctx, "user:1")
if result.Error != nil {
panic(result.Error)
}
fmt.Printf("User: %+v\n", result.Value)
}
type User struct {
ID int `json:"id"`
Name string `json:"name"`
Email string `json:"email"`
}
```
### Advanced Configuration
```go
// Create Redis configuration with advanced options
config := &cachex.RedisConfig{
Addr: "localhost:6379",
Password: "secret",
DB: 0,
PoolSize: 20,
MinIdleConns: 5,
MaxRetries: 3,
DialTimeout: 5 * time.Second,
ReadTimeout: 3 * time.Second,
WriteTimeout: 3 * time.Second,
HealthCheckInterval: 30 * time.Second,
HealthCheckTimeout: 1 * time.Second,
}
// Create Redis client
client, err := cachex.CreateRedisClient(config)
if err != nil {
panic(err)
}
defer client.Close()
// Create custom codec with options
jsonCodec := cachex.NewJSONCodecWithOptions(&cachex.JSONCodecOptions{
AllowNilValues: true,
PrettyPrint: false,
})
// Create key builder for namespaced keys
keyBuilder, err := cachex.NewBuilder("myapp", "production", "secret-key")
if err != nil {
panic(err)
}
// Create Redis cache with custom components
cache := cachex.NewRedisCache(client, jsonCodec, keyBuilder, nil)
defer cache.Close()
// Create typed cache
typedCache := cachex.NewTypedCache[User](cache)
// Use with context
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
// Cache operations
user := User{ID: 1, Name: "John Doe", Email: "john@example.com"}
result := <-typedCache.Set(ctx, "user:1", user, 10*time.Minute)
```
### Key Building System
```go
// Create key builder with namespacing
keyBuilder, err := cachex.NewBuilder("myapp", "production", "secret-key")
if err != nil {
panic(err)
}
ctx := context.Background()
// Build entity keys
userKey := keyBuilder.Build("user", "123")
// Returns: "app:myapp:env:production:user:123"
// Build list keys with filters
filters := map[string]any{
"status": "active",
"role": "admin",
}
listKey := keyBuilder.BuildList("user", filters)
// Returns: "app:myapp:env:production:list:user:"
// Build composite keys
compositeKey := keyBuilder.BuildComposite("user", "123", "org", "456")
// Returns: "app:myapp:env:production:user:123:org:456"
// Build session keys
sessionKey := keyBuilder.BuildSession("session-abc123")
// Returns: "app:myapp:env:production:session:session-abc123"
// Convenience methods
userKey = keyBuilder.BuildUser("123") // Same as Build("user", "123")
orgKey := keyBuilder.BuildOrg("456") // Same as Build("org", "456")
productKey := keyBuilder.BuildProduct("789") // Same as Build("product", "789")
orderKey := keyBuilder.BuildOrder("012") // Same as Build("order", "012")
// Parse keys back to components
entity, id, err := keyBuilder.ParseKey(userKey)
// Returns: entity="user", id="123", err=nil
```

MGet(ctx context.Context, keys []string) <-chan AsyncCacheResult[map[string][]byte]
MSet(ctx context.Context, items map[string][]byte, ttl time.Duration) <-chan AsyncCacheResult[bool]
Del(ctx context.Context, keys []string) <-chan AsyncCacheResult[int64]
Exists(ctx context.Context, key string) <-chan AsyncCacheResult[bool]
TTL(ctx context.Context, key string) <-chan AsyncCacheResult[time.Duration]
IncrBy(ctx context.Context, key string, delta int64) <-chan AsyncCacheResult[int64]
Close() error
}
```
**KeyBuilder Interface**
```go
type KeyBuilder interface {
Build(entity, id string) string
BuildList(entity string, filters map[string]any) string
BuildComposite(entityA, idA, entityB, idB string) string
BuildSession(sid string) string
}
```
**Codec Interface**
```go
type Codec interface {
Encode(v any) ([]byte, error)
Decode(data []byte, v any) error
Name() string
}
```
### Type-Safe Cache
```go
// Create typed cache for any type T
typedCache := cachex.NewTypedCache[User](cache)
// All operations are type-safe
result := <-typedCache.Get(ctx, "user:1")
if result.Error == nil {
user := result.Value // Type: User
fmt.Printf("User: %+v\n", user)
}
```
