goobs-cache

A versatile and efficient caching and state management solution for TypeScript and JavaScript applications. goobs-cache features multiple storage options, encryption, compression, and flexible data management across different environments.

Features

• Multiple storage options:
  • Serverless caching with LRU strategy
  • Client-side storage (cookies and session storage)
• Two-layer caching: Automatically syncs between serverless and client-side storage for optimal performance and offline capabilities.
• Cross-environment support: Works seamlessly in both client-side and server-side environments.
• Unified state management: Provides functionality similar to React's useContext and useState.
• Enhanced security: Implements AES-GCM encryption for data protection.
• Optimized storage: Utilizes compression to reduce storage footprint.
• TypeScript support: Offers strong typing for improved developer experience.

Installation

npm install goobs-cache

Or using yarn:

yarn add goobs-cache

Basic Usage

Here's a simple example of how to use goobs-cache:

import { serverless, session, cookie, twoLayer } from 'goobs-cache';

// Two-layer caching (automatically syncs between serverless and client-side)
await twoLayer.update('userProfile', 'userStore', { name: 'Alice', age: 28 });
const userProfile = await twoLayer.get('userProfile', 'userStore');
console.log(userProfile); // { name: 'Alice', age: 28 }

// Serverless caching
const serverlessAtom = serverless.atom('serverData', 'dataStore');
await serverlessAtom.set('Hello, Serverless!');
const serverValue = await serverlessAtom.get();
console.log(serverValue); // 'Hello, Serverless!'

// Client-side caching (session storage)
const sessionAtom = session.atom('Hello, Session!');
const [sessionValue, setSessionValue] = session.useAtom(sessionAtom);
console.log(sessionValue); // 'Hello, Session!'
setSessionValue('Updated Session Value');

// Client-side caching (cookies)
const cookieAtom = cookie.atom('cookieData', 'cookieStore');
await cookieAtom.set('Hello, Cookies!');
const cookieValue = await cookieAtom.get();
console.log(cookieValue); // 'Hello, Cookies!'

// Removal
await twoLayer.remove('userProfile', 'userStore');
await serverlessAtom.remove();
await cookieAtom.remove();

// Clearing all caches
await twoLayer.clear();
await serverless.clear();
await cookie.clear();

// Updating configuration
twoLayer.updateConfig();
serverless.updateConfig();
session.updateConfig();
cookie.updateConfig();

Advanced Features

goobs-cache offers advanced capabilities for complex use cases:

• Two-layer caching: Automatically synchronizes data between serverless and client-side storage, providing seamless offline capabilities and improved performance.
• Automatic client-side caching: When using the serverless mode on the client-side, data is automatically cached in session storage for faster subsequent access.
• Flexible storage options: Choose between twoLayer, serverless, session, and cookie modes to best suit your application's needs.

Configuration

Configure goobs-cache using a .cache.config.ts file in your project's root. Here's a comprehensive example:

import { CacheConfig, EvictionPolicy, LogLevel } from 'goobs-cache';

const cacheConfiguration: CacheConfig = {
  serverless: {
    cacheSize: 10000,
    cacheMaxAge: 86400000,
    persistenceInterval: 600000,
    maxMemoryUsage: 1073741824,
    evictionPolicy: 'lru' as EvictionPolicy,
    prefetchThreshold: 0.9,
    forceReset: false,
    compression: {
      compressionLevel: -1,
    },
    encryption: {
      algorithm: 'aes-256-gcm',
      encryptionPassword: 'your-secure-encryption-password-here-serverless',
      keyCheckIntervalMs: 86400000,
      keyRotationIntervalMs: 7776000000,
    },
  },
  session: {
    cacheSize: 5000,
    cacheMaxAge: 1800000,
    evictionPolicy: 'lru' as EvictionPolicy,
    compression: {
      compressionLevel: -1,
    },
    encryption: {
      algorithm: 'aes-256-gcm',
      encryptionPassword: 'your-secure-encryption-password-here-session',
      keyCheckIntervalMs: 86400000,
      keyRotationIntervalMs: 7776000000,
    },
  },
  cookie: {
    cacheSize: 1000,
    cacheMaxAge: 604800000,
    maxCookieSize: 4096,
    evictionPolicy: 'lru' as EvictionPolicy,
    compression: {
      compressionLevel: -1,
    },
    encryption: {
      algorithm: 'aes-256-gcm',
      encryptionPassword: 'your-secure-encryption-password-here-cookie',
      keyCheckIntervalMs: 86400000,
      keyRotationIntervalMs: 7776000000,
    },
  },
  global: {
    keySize: 256,
    batchSize: 100,
    autoTuneInterval: 3600000,
    loggingEnabled: true,
    logLevel: 'debug' as LogLevel,
    logDirectory: 'logs',
  },
};

export default cacheConfiguration;
