Fast and simple MCV in nodejs
var app = require("nodejs-mvc");
var appVars = app.getVars();
var server = require("http").createServer(function( request, response, next ) {
app.handleServerResponse( request, response, next );
});
app.sessionCookieName("ssid");
app.sessionDynCookieName("ssid");
app.sessionDynCookieDomain(false);
app.sessionDynAutoUpdate(true);
app.sessionDynExpire(60*60*2);
app.setRootPath( __dirname );
app.setPublicPath( __dirname+'/public');
app.setModulePath( __dirname+'/app/modules');
app.runBootstrap();
server.listen(8080); --------------------------

On template Rendering we have following variables
// variables that a sent from controllers
var vars = {};
var env = {
error : [],
vars : envVars,
path : "", // file path of current rendered template
dirname : "", // dirname of current rendered template
render : function( text, vars, env ) {}, // render function
renderFile : function( file, vars, callback ) {}, // render file function
// callback( error {{ [] or false }}, htm)
};
// env vars sent from app
env.vars = {
response : [object] // http reponse object
} // file app/modules/index/controller/pageviews.js
// file reprezents action pageviews from controller index
var _vars = {
pageviews : 0
};
module.exports = {
public : true,
capture : function( request, response, app, controller, action ) {
// increasing pageviews
// sending pageviews to view
controller.render( response, 'index', { pageviews: (++_vars.pageviews) });
}
