@lti-tool/memory

Installation

npm install @lti-tool/memory

Quick Start

import { LTITool } from '@lti-tool/core';
import { MemoryStorage } from '@lti-tool/memory';

// Generate keypair (use proper key management in production)
const keyPair = await crypto.subtle.generateKey(
  {
    name: 'RSASSA-PKCS1-v1_5',
    modulusLength: 2048,
    publicExponent: new Uint8Array([1, 0, 1]),
    hash: 'SHA-256',
  },
  true,
  ['sign', 'verify'],
);

const storage = new MemoryStorage();

const ltiTool = new LTITool({
  stateSecret: new TextEncoder().encode('your-secret'),
  keyPair,
  storage,
});

Features

• Zero Dependencies - No external storage required
• Fast Performance - Sub-millisecond operations
• Development Ready - Perfect for local development
• Auto-cleanup - Expired nonces and sessions removed automatically

API Reference

• API Reference - Complete API documentation

Configuration

Basic Usage

const storage = new MemoryStorage();

With Logger

import pino from 'pino';

const storage = new MemoryStorage({
  logger: pino(),
});

Limitations

• No Persistence - Data lost on restart
• Single Instance - Not suitable for multi-server deployments
• Memory Usage - All data stored in RAM
• No Clustering - Cannot share state across processes

Performance

• All operations: <1ms
• Memory efficient: Automatic cleanup of expired data
• No I/O blocking: Synchronous operations
