routes 0.1.2

simple server routing

##ROUTES

Is a simple server routing via a single routes.dart file

routes builds on route and params package route and params

1. add dependencies to pubspec

   route: ">=0.4.6 <0.5.0"
   routes: ">=0.0.1 <0.1.0"
   

2. create a routes file ###ROUTES

inside projectRootFolder/routes.dart

   part of sampleServerGui;
  
   final Map serverRoutes={
     'byeJs':{'url':new UrlPattern(r'/byeJs'),'action': byeJs },
     'helloDart':{'url':new UrlPattern(r'/helloDart'),'method':'GET','action': helloDart }
   };

here we see 2 routes 'byeJs' and 'helloDart'

routes always have a

url -> url pattern and an

action -> called method and an optional

method -> that currently handels 'PUT' and 'GET'

3. create the simple server with functions for each specified action (helloDart,byeJs) ###SERVER

projectRootFolder/bin/simpleServer.dart

   library sampleServerGui;
   
   import "dart:io";
   import 'dart:convert';
   import 'package:route/url_pattern.dart';
   import 'package:routes/server.dart';
  
   part '../routes.dart';
  
   void main() {
     HttpServer.bind("127.0.0.1", 8079).then((server) {
       var router = initRouter(server, serverRoutes);
     }, onError: printError);
   }
  
   void printError(error) => print(error);
  
   helloDart(Map params, HttpResponse res){
     Map newMap = {"language":params["language"]};
     if(params["language"] == "Dart"){
       newMap["text"]="Hello";
     }else{
       newMap["text"]="GOODBYE";
     }
     res.write(JSON.encode(newMap));
     res.close();
   }

   byeJs(Map params, HttpResponse res){
     //do stuff
   }

now you can talk to the server eg with http://127.0.0.1:8079/helloDart?language=Dart

###WHATS HAPPENING

the Magic happens here

  var router = initRouter(server, serverRoutes);

it automatically generates a router that will use the specified routes in routes.dart

the action specified inside the routes will recieve 2 parameters

**a Map params **-> including the parameters send in the request **a HTTPResponse res **
