• in app.js

   
       var sledge = require("express-sledge");
   	sledge(app, require("./router.json"),path.join(__dirname, "routes"));
   

• write a controller , index.js

   
   	exports.execute = function(req,res){
   		//just like express.router function
   		
   		//this will render the configured view
   		res.result("success",{data:""});
   		
   		//if something goes wrong , you can render the error view
   		res.result("error");
   		
   		//you can also call the any methods of  express.Response
   		res.send("welcome");
   		
   	}

API

• sledge(urlPattern , config , baseControllerPath);

  • urlPattern any pattern supported by express

  • config Object , see lib/config.json

  • baseControllerPath path of routers directory. require("path").join(__dirname , "routes")

  This will parse the config to express.Router and add function result to express.Response . You can use this function to choose which view to render. Of course , you can still use express.Response.render or other functions.
