quickstart
var express = require('express');
var taters = require('taters');
var app = express();
app.set('view engine', 'hbs'); // or jade or whatevs
app.set('views', __dirname + '/views');
// let tater setup the magic
// you don't have to do anything else to get fingerprinting
app.use(taters({ cache: true || false });
// you can now serve static content with the regular static middleware
// no need to set a longer cachetime or anything since taters does that for us
app.use(express.static(__dirname + '/public'));
// render your views as before
// tater will replace script, link, img urls with fingerprinted ones
app.get('/', function(req, res, next) {
res.render('index');
});api
taters(opt, [middleware])
middleware is an optional function which will be called when /static/ middleware is encountered. You can do things like set longer expiries, better cache headers, etc...
By default, taters middleware sets an expiry of 1 year. This lets browsers, proxies, and CDNs cache the resource for a long time since the hash changes when the resource changes.
options
Taters accepts some options to configure behavior
| option | type | default | description |
|---|---|---|---|
| cache | Boolean | false | true will cache url hashes to be cached |
| prefix | String | prefix all changed url with this path |
CDN
Taters makes it very easy to use a CDN in production. Simply set the prefix option to the domain of your CDN and your resources will be served via CDN.
