omni-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)
cacheBust.handler(app,{
version: '1.1',
packageLocation: '../yourpackagelocation',
minifiedDir: ['/dir1/', '/dir2/']
});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.
minifiedDir: path of all your self-minified static file. All the minified file must locate in the same directory with original file.
Production Setting
You can set production parameter in your package.json, default is false. If it is false, all minified file will be change to original file in front side.
Difference production and development
The above example is the output if the production parameter is false. 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" />
