Express.js caching middleware

Install

yarn install express-rc

Usage

'use strict';

const express = require('express');
const redis = require('redis');
const cache = require('cache');

const app = express();

app.use(cache({
    ttl: 60 // How long (in seconds) to hold onto cached responses
    enabled: true, // Enable caching (setting exists to easily disable in specific environments)
    includeBody: true, // Include the body in hashing the request
    disabled: [ // Specify some routes that shouldn't be cached
        '/ping',
        '/auth'
    ],
    headers: [ // Any unique headers you want to include when hashing the request
        'X-Access-Token'
    ],
    client: redis.createClient() // A node redis client
}));

app.use('/', (req, res) => {
    res.ttl(5) // Optionally override the global ttl in middleware
    return next();
});
