go-store

Group-namespaced SQLite key-value store with TTL expiry, namespace isolation, quota enforcement, and a reactive event system. Backed by a pure-Go SQLite driver (no CGO), uses WAL mode for concurrent reads, and enforces a single connection to keep pragma settings consistent. Supports scoped stores for multi-tenant use, Watch/Unwatch subscriptions, and OnChange callbacks for go-ws event streaming.

Quick Start

package main

import (
	"fmt"
	"time"

	"dappco.re/go/core/store"
)

func main() {
	storeInstance, err := store.New("/path/to/store.db") // or store.New(":memory:")
	if err != nil {
		panic(err)
	}
	defer storeInstance.Close()

	storeInstance.Set("config", "theme", "dark")
	storeInstance.SetWithTTL("session", "token", "abc123", 24*time.Hour)
	value, err := storeInstance.Get("config", "theme")
	fmt.Println(value, err)

	// Watch for mutations
	watcher := storeInstance.Watch("config", "*")
	defer storeInstance.Unwatch(watcher)
	go func() {
		for event := range watcher.Events {
			fmt.Println(event.Type, event.Key)
		}
	}()

	// Scoped store for tenant isolation
	scopedStore, _ := store.NewScoped(storeInstance, "tenant-42")
	scopedStore.Set("prefs", "locale", "en-GB")
}
