cache-bust
Use cache busting in express. Adds a version query string to ressources.
Usage with express
var express = require('express');
var cacheBust = require('cache-busted');
var app = express();
cacheBust.handler(app);This exposes the function cacheBust in your app locals. Enabling you to do the following (example using jade):
head
title Hello World
!= cacheBust('/public/js/app.js')
!= cacheBust('/public/css/style.css')
!= cacheBust('/public/css/style', 'css')Output:
<head>
<title>Hello World</title>
<script type="text/js" src="/public/js/app.js?v=1.0.0" />
<link rel="stylesheet" href="/public/css/style.css?v=1.0.0" />
<link rel="stylesheet" href="/public/css/style.css?v=1.0.0" />
</head>Options
Add the options to the handler call: cacheBust.handler(app, options)
version: Use this exact version. Default: null which will make this module look for a package.json in the folder below
packageLocation: Path to the package.json. Defaults to ../../package.json.
Difference production and development
The above example is the output if the NODE_ENV environment variable is set to production or integration. Otherwise it also appends the current timestamp so that each request will load all new dependencies. Example:
<link rel="stylesheet" href="/public/css/style.css?v=1.0.0-1432576223502" />
