api-cache 🗄️

A tiny, flexible HTTP response caching middleware for Node.js. Supports in-memory, Redis, and custom backends.

Features

• ⚡ In-memory LRU cache out of the box
• 🔴 Optional Redis backend for distributed caching
• 🎯 Route-level cache control with pattern matching
• 🔑 Smart cache key generation (method + path + query + headers)
• 📊 Cache hit/miss headers for debugging
• 🧹 Automatic TTL-based expiration
• 🪶 Express & Koa compatible

Quick Start

import express from 'express';
import { apiCache } from 'api-cache';

const app = express();

// Cache all GET requests for 60 seconds
app.use(apiCache({ ttl: 60 }));

// Route-specific caching
app.get('/api/users', apiCache({ ttl: 300 }), (req, res) => {
  res.json(users);
});

// Skip cache for authenticated requests
app.use(apiCache({
  ttl: 120,
  skip: (req) => !!req.headers.authorization,
}));

Redis Backend

import { apiCache, RedisStore } from 'api-cache';

app.use(apiCache({
  ttl: 300,
  store: new RedisStore({ url: 'redis://localhost:6379' }),
}));
