Addons

Coming Soon

All official addon packages are under active development. The interfaces they implement are stable today — you can build your own adapters while the official packages ship.

Addons are separate Go modules that implement the core interfaces. Install only what you need.

Building Your Own Adapter

Every addon is just a struct that implements a core interface. You can build your own today:

// Implement Cache with in-memory storage
type InMemoryCache struct {
    mu    sync.RWMutex
    store map[string][]byte
}

func (c *InMemoryCache) Get(ctx context.Context, key string) ([]byte, error) {
    c.mu.RLock()
    defer c.mu.RUnlock()
    v, ok := c.store[key]
    if !ok {
        return nil, errors.New("key not found")
    }
    return v, nil
}

// ... implement Set, Delete, Exists
