Because of Stefano Fois comment<\/a> I decided to write\u00a0an example about how to create a minimizer servlet for Domino which compresses JavaScript resources on the fly. This is, again, a simple Proof-Of-Concept, nothing more and nothing less.<\/p>\n

First, I\u00a0downloaded\u00a0the YUICompressor<\/a>, a Java based minimizer for JavaScript code from the project page. There are other compressors outside, I decided to use this one because it was the first result in my StartPage.com search<\/a>.<\/p>\n

The project is a single jar file and can be\u00a0easily\u00a0imported into an existing Domino database, in my case to my demonstration NAPI.nsf<\/em>.<\/p>\n

\"\"<\/p>\n

The next step is to create a servlet and a servlet factory, the basics are described here<\/a>. To enable the servlet, an additional service file\u00a0is required.<\/p>\n

\"\"<\/p>\n

The file com.ibm.xsp-adapter.servletFactory<\/em>\u00a0contains the name of the factory class:<\/p>\n

ch.hasselba.jsf.servlet.MinimizerServletFactory<\/code><\/pre>\n
The servlet factory is simple, it just defines the servlet class to use and the path which the servlet listens to requests:<\/p>\n
package ch.hasselba.jsf.servlet;\r\n\r\nimport javax.servlet.Servlet;\r\nimport javax.servlet.ServletException;\r\n\r\nimport com.ibm.designer.runtime.domino.adapter.ComponentModule;\r\nimport com.ibm.designer.runtime.domino.adapter.IServletFactory;\r\nimport com.ibm.designer.runtime.domino.adapter.ServletMatch;\r\n\r\npublic class MinimizerServletFactory implements IServletFactory {\r\n\r\n\u00a0\u00a0 \u00a0private static final String SERVLET_WIDGET_CLASS = \"ch.hasselba.jsf.servlet.MinimizerServlet\";\r\n\u00a0\u00a0 \u00a0private static final String SERVLET_WIDGET_NAME = \"JS Minimizer\";\r\n\r\n\u00a0\u00a0 \u00a0private ComponentModule module;\r\n\r\n\u00a0\u00a0 \u00a0public void init(ComponentModule module) {\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0this.module = module;\r\n\u00a0\u00a0 \u00a0}\r\n\r\n\u00a0\u00a0 \u00a0public ServletMatch getServletMatch(String contextPath, String path)\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0throws ServletException {\r\n\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0String servletPath = \"\";\r\n\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0if (path.contains(\"\/minimizer\")) {\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0String pathInfo = path;\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0return new ServletMatch(getWidgetServlet(), servletPath, pathInfo);\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0}\r\n\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0return null;\r\n\u00a0\u00a0 \u00a0}\r\n\r\n\u00a0\u00a0 \u00a0public Servlet getWidgetServlet() throws ServletException {\r\n\u00a0\u00a0 \u00a0\u00a0\u00a0 \u00a0return module.createServlet(SERVLET_WIDGET_CLASS, SERVLET_WIDGET_NAME, null);\r\n\u00a0\u00a0 \u00a0}\r\n\r\n}<\/code><\/pre>\n
The servlet is now reachable by the following URL<\/p>\n
http:\/\/example.com\/path\/to\/db.nsf\/xsp\/minimizer\/<\/pre>\n
How does the minimizer servlet work? It appends all required files into a single string and compresses the string\u00a0before sending the result to the browser. So the first information needed is which files should be used. This can be done with the parameter „files<\/em>„, the list of files is concatenated with „+<\/em>„:<\/p>\n
http:\/\/example.com\/path\/to\/db.nsf\/xsp\/minimizer\/?files=file1.js+file2.js+ ...<\/pre>\n
The given files are then loaded via NAPI into a large StringBuffer and then compressed and mimimized by YUI and GZIP.<\/p>\n

For testing purposes I imported an uncompressed version of jQuery<\/a>\u00a0and created a file named helloWorld.js<\/em>. The helloWorld.js<\/em> contains a single function only, just to test and verify the outcome of the servlet.<\/p>\n
\"\"<\/p>\n
Then, I created a test.html<\/em>, a simple HTML page which loads the mimimized JavaScript files:<\/p>\n
<html>\r\n <body>\r\n   <h1>Test<\/h1>\r\n   <script src=\".\/xsp\/minimizer\/?files=jquery-1.11.1.js+helloWorld.js\">\r\n   <\/script>\r\n <\/body>\r\n<\/html><\/code><\/pre>\n
This is how the WebContent<\/em> folder looks like in package explorer:<\/p>\n
\"\"<\/p>\n
When opening the test.html<\/em> page, you can see that only a single request is made to load the data from the servlet:<\/p>\n
\"\"<\/p>\n
The size of the response is only 30 % of the original jQuery source request (which is GZIPed too):<\/p>\n
\"\"<\/p>\n
When testing the code in the Firebug console, everything is working as expected. The „HelloWorld“ function shows an alert…<\/p>\n
\"\"<\/p>\n
and jQuery is defined:<\/p>\n
\"\"<\/p>\n
The performance on my test server is very good, without code optimization or caching of the generated JavaScript elements.<\/p>\n","protected":false},"excerpt":{"rendered":"
Because of Stefano Fois comment I decided to write\u00a0an example about how to create a minimizer servlet for Domino which compresses JavaScript resources on the fly. This is, again, a simple Proof-Of-Concept, nothing more and nothing less.
