express-lru

express-lru

Express middleware that serves as a stopgap for Varnish – for times when you don't have time to set up Varnish or want something simpler. A few notes:

• It will only cache 200-status responses.
• Response headers (like Content-Type) will be cached and served like normal.
• Supports JSON, Buffers, and Strings.
• Has a "skip" option that allows for control of what requests bypass the cache. In most cases you’ll want to return true for logged in users.

Example Usage

var expresslru = require('express-lru');
var cache = expresslru({
	max: 1000,
	ttl: 60000,
	skip: function(req) {
		return !!req.user;
	}
});

app.get('/myroute', cache, function(req, res, next) {
    // ...
});
