README

[DEPRECATED]

Please I have no longer time for maintaining this package. Previous version depended on old version of uglify-js which had security issues https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-8857 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-8858 PLEASE DO NOT USE THIS PACKAGE

jcash

This project is mostly for adapting solutions out there for my personal use. For the size of the image you have to install GraphicsMagick (http://www.graphicsmagick.org/)

Basic server setup

var express = require('express');
var staticHandler = require('jcash');
var app = express.createServer();
var jsManager = staticHandler.getJsManager();
var cssManager = staticHandler.getCssManager();
var imageManager = staticHandler.getImageManager({path : __dirname + '/public/img', hasGm : true});

/* parsing the configuration */
jsManager.parseConfig(staticConfig.js);
cssManager.parseConfig(staticConfig.css);


/* for serving the contents */
staticHandler.bootstrap(app);

/* Adding template functions */
app.dynamicHelpers(staticHandler.dynamicHelpers);

/* generate the cache */
jsManager.preRenderAll();
cssManager.preRenderAll();
imageManager.fetchFiles();

Content template (ejs templates)

<% addBottomScript('some javascript including script-tag here') %>
<%- renderImageTag('/img/icons/loading.gif') %>

layout template with automatic location mapping

<html>
    <head>
    <%- renderStyleTags() %>
    </head>
    <body>
    <%- body %>
    <%- renderScriptTags() %>
    <%- renderBottomScripts() %>
    <script type="text/javascript">
    $(function(){
        VNF.util.Loading.loadingImage = "<%- getImageUrl('/img/icons/loading.gif') %>";
    });
    </script>
    </body>
</html>
