Laravel Hyper-Cache-IO

Laravel Hyper-Cache-IO is an ultra-fast, distributed cache driver for Laravel applications. By combining L1 in-memory caching with a persistent SQLite WAL backend, it delivers exceptional performance and reliability without the overhead of Redis or Memcached.

Designed for modern PHP environments like FrankenPHP, Swoole, and traditional Nginx/FPM, it features a lightweight internal HTTP API for seamless multi-server synchronization.

⚡ Features

• 🚀 High Performance: Built on SQLite WAL (Write-Ahead Logging) for lightning-fast reads and writes.
• 🧠 L1 In-Memory Cache: Ephemeral memory caching for instant access during the request lifecycle.
• 🐹 Go Server (New): Optional standalone Go-based binary for high-concurrency inter-server synchronization.
• 🔄 Active-Active HA Mode: Fully synchronized multi-node clusters using binary TCP replication.
• 🛡️ Service Management: Built-in support for running as a systemd (Linux) or launchd (macOS) service with auto-restart.
• 🔒 Distributed Locking: Full support for atomic locks across multiple servers.
• ⚡ Atomic Operations: Native support for Cache::add() and atomic increment/decrement.
• 🌐 HTTP Synchronization: Robust Primary/Secondary architecture for multi-node setups.
• 🧹 Background GC: Proactive background cleanup of expired items and locks to ensure memory efficiency.
• 🛡️ Secure: Token-based authentication protects your internal cache API.
• ✅ Modern Compatibility: Fully supports Laravel 10.x, 11.x, and 12.x.

📦 Installation

Install the package via Composer:

composer require iperamuna/laravel-hypercacheio

Run the installation command to configure the package:

php artisan hypercacheio:install

⚙️ Configuration

1. Set the Cache Driver

Update your .env file to use hypercacheio:

CACHE_DRIVER=hypercacheio

2. Configure Server Roles

Hyper-Cache-IO uses a simple Primary/Secondary architecture. You can also run it in standalone mode (Primary only).

Primary Server (Writer)

A single "Primary" node handles all write operations to the database. You can optionally list secondary server URLs so the primary replicates writes to them.

HYPERCACHEIO_SERVER_ROLE=primary
HYPERCACHEIO_API_TOKEN=your-secr3t-t0ken-here

# Optional: comma-separated list of secondary server URLs for replication.
# Invalid URLs are silently ignored. Whitespace around URLs is trimmed.
HYPERCACHEIO_SECONDARY_URLS="https://s2.example.com,https://s3.example.com"

# Optional: fire-and-forget async replication (default: true)
HYPERCACHEIO_ASYNC=true

Secondary Server (Reader)

"Secondary" nodes read from their local copy (synced via shared volume or future replication features) and forward writes to the Primary via HTTP.

HYPERCACHEIO_SERVER_ROLE=secondary
HYPERCACHEIO_PRIMARY_URL=https://primary.example.com/api/hypercacheio
HYPERCACHEIO_API_TOKEN=your-secr3t-t0ken-here

3. Advanced Configuration

Publish and fine-tune the config file at config/hypercacheio.php:

return [
    // Server role: 'primary' or 'secondary'
    'role' => env('HYPERCACHEIO_SERVER_ROLE', 'primary'),

    // Primary server API URL (used by secondary nodes)
    'primary_url' => env('HYPERCACHEIO_PRIMARY_URL', 'http://127.0.0.1/api/hypercacheio'),

    // Comma-separated secondary server URLs for write replication
    // Invalid URLs are silently discarded to prevent misconfiguration
    'secondaries' => HypercacheioSecondaryUrls(env('HYPERCACHEIO_SECONDARY_URLS', ''), ','),

    // Shared secret for inter-server authentication (X-HyperCacheio-Token header)
    'api_token' => env('HYPERCACHEIO_API_TOKEN', 'changeme'),

    // HTTP timeout in seconds for peer-server requests (recommended: 1–3)
    'timeout' => 1,

    // Fire-and-forget async replication (lower latency, silent failures)
    'async_requests' => env('HYPERCACHEIO_ASYNC', true),

    // SQLite database directory (auto-created by the install command)
    'sqlite_path' => storage_path('hypercacheio'),
];

4. Environment Variables Reference

🐹 Go Server Implementation (Experimental)

For high-traffic applications, you can use the standalone Go server instead of the built-in Laravel routes. This provides ultra-low latency and handles concurrent synchronization requests more efficiently.

With version 1.5.0, the Go server now connects directly to the SQLite database (storage/hypercacheio/hypercacheio.sqlite) to process caching and locks natively using PHP serialization bindings, bypassing the php artisan bootstrap entirely. Response times drop from ~50ms down to < 1ms.

Binaries are stored in resources/hypercacheio/bin/ and can be committed to your repository for seamless deployment without requiring a Go compiler on production servers.

1. Enable Go Server

Update your .env:

HYPERCACHEIO_SERVER_TYPE=go
HYPERCACHEIO_GO_DIRECT_SQLITE=true

# External IP that secondary servers use to reach this node
HYPERCACHEIO_GO_HOST=10.80.3.131
HYPERCACHEIO_GO_PORT=8185

# IP the daemon binds to — 0.0.0.0 (default) listens on all interfaces.
HYPERCACHEIO_GO_LISTEN_HOST=0.0.0.0

2. Active-Active HA Mode (TCP Replication)

As of version 1.6.0, Hyper-Cache-IO supports a robust Active-Active HA architecture. Multiple application servers can each run their own local Go cache node, with all nodes synchronizing state in real-time over a dedicated binary TCP protocol.

• Full-Mesh Replication: Every write on one node is instantly broadcast to all configured peers.
• Bootstrap Sync: When a new node joins the cluster, it automatically requests a full state dump from existing peers.
• Zero-Wait Primary: No more bottlenecking on a single "Primary" URL. Your app talks to its local node, and replication happens in the background.

To enable HA Mode, configure your peers in .env:

HYPERCACHEIO_HA_ENABLED=true
HYPERCACHEIO_REPL_PORT=7400

# Comma-separated list of peer IP:REPL_PORT addresses
HYPERCACHEIO_PEER_ADDRS=10.0.0.2:7400,10.0.0.3:7400

The hypercacheio:go-server command will automatically configure the Go binary to use your application's absolute database path (config('hypercacheio.sqlite_path')) and cache prefix (config('cache.prefix')).

2. Compile & Start

The package includes a full management CLI for the Go daemon:

# 🛠️ Compile the binary for your system (detects macOS/Linux, all architectures)
php artisan hypercacheio:go-server compile

# 🚀 Start the server as a background process
php artisan hypercacheio:go-server start

# 📊 Check daemon status (PID / systemd / launchd / process scan)
php artisan hypercacheio:go-server status

# 🔄 Restart the daemon (Artisan managed)
php artisan hypercacheio:go-server restart

# 🛑 Stop the daemon
php artisan hypercacheio:go-server stop

3. Run as a System Service

Generate service configuration files for your OS, then install and manage them via Artisan:

# Step 1: Generate the service file (systemd for Linux, launchd for macOS)
php artisan hypercacheio:go-server make-service

# Step 2: Install the service (one-time manual step per OS):
# Linux:  sudo cp hypercacheio-server.service /etc/systemd/system/
# macOS:  cp iperamuna.hypercacheio.server.plist ~/Library/LaunchAgents/

# Step 3: Manage via Artisan
php artisan hypercacheio:go-server service:start   # Load and start the service
php artisan hypercacheio:go-server service:restart # Cycle the service
php artisan hypercacheio:go-server service:stop    # Stop the service
php artisan hypercacheio:go-server service:status  # View service status (systemd/launchd output)
php artisan hypercacheio:go-server service:remove  # Disable and remove the service

🔌 Connectivity Check

To verify that your server can communicate with the configured Primary/Secondary nodes, run the built-in connectivity check command:

php artisan hypercacheio:connectivity-check

This command:

• Identifies server type (LARAVEL or GO) with host and port
• Pings the local node first via 127.0.0.1 (falls back to configured host)
• Tests Ping, Add, Get, Put, Delete, Lock against all configured endpoints
• Reports OS-specific firewall advice (ufw, firewalld, socketfilterfw) when a connection fails

🛠️ Usage

Use the standard Laravel Cache Facade. No new syntax to learn!

use Illuminate\Support\Facades\Cache;

// ✅ Store Data
// Automatically handles L1 memory + SQLite persistence + Primary sync
Cache::put('user_preference:1', ['theme' => 'dark'], 600);

// ✅ Retrieve Data
// Checks L1 memory first, then SQLite
$prefs = Cache::get('user_preference:1');

// ✅ Atomic Addition
// Only adds if key doesn't exist (concurrency safe)
Cache::add('job_lock:123', 'processing', 60);

// ✅ Atomic Locking
// Distributed locks work across all servers
$lock = Cache::lock('processing-job', 10);

if ($lock->get()) {
    // Critical section...
    
    $lock->release();
}

🔌 Internal API

The package exposes a lightweight internal API for node synchronization. Each endpoint is secured via X-Hypercacheio-Token.

✅ Testing

You can run the full test suite (Unit & Integration) using Pest:
