FastBoot Memcached Cache

This is similar to tomdale/fastboot-redis-cache, and its Memcached version.

Installation

$ npm install --save ursm/fastboot-memcached-cache

Please install either memjs or memcached according to your preference.

$ npm install --save memjs
(or)
$ npm install --save memcached

Tip: Since all Memcached add-ons of Heroku require SASL authentication, you should use memjs. Strangely, Memcached in Google App Engine does not work well with memjs.

Usage

const FastBootAppServer = require('fastboot-app-server');
const MemcachedCache    = require('fastboot-memcached-cache');

const cache = new MemcachedCache({
  servers: 'localhost:11211',
  expiration: 5 * 60,

  cacheKey(path, request) {
    return path;
  }
});

const server = new FastBootAppServer({
  cache
});

Configuration Options

expiration (optional)
