• write a controller , index.js

  	```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](./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.
