koa-rest-cache

Very simple cache middleware for restful apis in koa. This aims to be a very thin wrapper over your restful APIs. It simply stores the response body of requests matching a given pattern in memory. There is no way to read, write, or clear the cache, it should just work.

Installation

npm install koa-rest-cache

Usage

var app = require('koa')();
var cache = require('koa-rest-cache');

app.use(cache({
  pattern: "/api/**/*",
  maxAge: 600000 // ms
}));

API

cache(options) A function that takes a single options argument, and returns a function generator that is intended to be passed to koa's app.use function.

Options

• pattern A String or Array of Strings to match incoming request paths against. Supports glob matching and other features provided by minimatch. If no pattern is provided all requests will be cached.
• maxAge A length of time in milliseconds that something should remain in the cache. Defaults to 600000ms (10 minutes).
• method A String or Array of Strings to match incoming request methods against. Defaults to GET
