Nodejs minification middleware for express/connnect with in memory caching support
Nodejs css/js minification middleware for connect/express with in-memory caching support
minimonster was created because I needed a css/js minification middleware for my express stack that had the following requirements:
- minify BOTH css and js files
- switch between different minification frameworks out there (google closure, yui, uglify, swish)
- add in memory support so minified css and js could be served from memory instead of hitting the disk every time (recommended for high performance production environments)
- graceful degredation on any type of failure and let express.static() serve as a fallback
- module could be used as an object outside of middleware (express/connect) environment
npm install minimonster
If you find any bugs, please help me fix them! Thanks.
You can just drop minimonster into your express middleware stack. The minimum you need is the
src option, which is the path to the directory containing all your public css and js files.
var minimonster = require'minimonster'middleware;appuseminimonsterminifysrc: __dirname + '/public';
If you are using minimonster as middleware in an express/connect app. Make sure that minimonster is above the
appuseexpresscompress;// minimonster needs to comes before express.static in the middleware stack or it will never work!!!appuseminimonsterminifysrc: __dirname + '/public';// express.static will service as a fallback in case minimonster cannot serve the request for whatever reasonappuseexpressstatic__dirname + '/public' maxAge: 86400000 ;
appuseminimonsterminifysrc: __dirname + '/public' // requireduseInMemoryCache: true // defaults to trueinMemoryCacheTTL: 10800 // defaults to 3 hourscacheDirectoryName: "_mm" // defaults to "_mm"cacheExtension: ".mini" // defaults to ".mini"debugMode: false // defaults to falsecssCompressor: 'yui-css' // defaults to "yui-css"jsCompressor: 'uglifyjs' // defaults to "uglifyjs"maxAge: 86400000 // default to 1 day;
This is the path to the public directory containing all your css and js files. This is the folder minimonster will look into to compress and serve files from.
Flag telling minimonster to store results in memory cache or not. If this is set to true then minimonster will agressively cache all minified content into it's in-memory cache so that it minimizes physical disk access. This is recommended for high performance production environments.
Time to live in milliseconds of in memory cache objects before eviction
Name of the directory that cached versions of the minified files are saved into. This is not to be confused with the in memory cache. Once a file has been minified, it will be stored into this directory so that minification does not need to happen again. As minification is a relatively CPU intensive process, we do not want to minify something we've already minified.
This gets appended to the name of minified files. For instance if you have a file called
application.js the new minified file will be called
Gives verbose output to console if set to true
The compression engine for css files. Options are "yui-css", "sqwish"
The compression engine for js files. Options are "gcc" (google closure compiler), "yui-js", "uglifyjs"
The maxAge of the http Cache-Control headers for static files in milliseconds.
As of node-minify v0.8.1 it supports the following compression schemes:
It will throw an error if you try with CSS files.
It will throw an error if you try with CSS files.
Sqwish can compress only CSS files.
It assumes you have Java installed on your environment for both GCC and YUI Compressor. To check, run:
inMemoryCacheTTL option can be used to control the TTL of in memory cache objects. The cache eviction cycle is run every 120 seconds.
Minimonster does a check against the last-modified timestamp on a file before compression, so if a cached version is out of date, then it will automatically re-cache a copy of the file - this should not be confused with the in-memory-cached copy, which must expire before minimonster will stop serving it.
Stopping and restarting your app will destory all in-memory cache values.
