REST架构网站改写:前端MVC - Angular.js,Web框架 - Express.js, 数据库 - MongoDB

  Coenraets分享了自己开发的一个Single Page Restful网站(http://coenraets.org/blog/2012/10/nodecellar-sample-application-with-backbone-js-twitter-bootstrap-node-js-express-and-mongodb)。

  他利用多种不同的前后端技术改写了这个项目,大致有以下这些:

  CSS库 - Bootstrap;

  前端MVC - Backbone.js,Angular.js;

  Web框架 - Express.js(Node.js)、PHP、Java ;

  数据库 - MongoDB、MySQL。

  其中,我最感兴趣Angular + Express + MongoDB的组合,Coenraets恰好没有实现;再加之Angular新版本改进颇大,尤其是Coenraets的实现没有使用angular.modular,所以我做了些改写,核心代码如下。

  Express Server部分:监听和响应客户端HTTP请求。

1 app.get('/wines', wine.findAll);
2 app.get('/wines/:id', wine.findById); //retrieve
3 app.post('/wines', wine.addWine);  //create
4 app.put('/wines/:id', wine.updateWine);  //update
5 app.delete('/wines/:id', wine.deleteWine);  //delete

  前端MVC架构:响应用户请求,完成大部分UI逻辑

  controller.js

 1 angular.module('controller', ['service']).
 2     config(function($routeProvider) {
 3         $routeProvider.when('/wines', {templateUrl:'tpl/welcome.html'}).
 4             when('/addWine',{templateUrl:'tpl/wine-details.html', controller:AddWineCtrl}).
 5             when('/wines/:wineId', {templateUrl:'tpl/wine-details.html', controller:WineDetailCtrl}).
 6             otherwise({redirectTo:'/wines'});
 7     });
 8 
 9 function WineListCtrl($scope, Wine) {
10     Wine.query(function(wines) {
11         $scope.wines = wines;
12     });
13 }
14 
15 function AddWineCtrl($scope, $location,  Wine) {
16     // POST /wines
17     $scope.saveWine = function() {
18         Wine.save($scope.wine, function() {
19             $location.path("/wines");
20         });
21     };
22 }
23 
24 function WineDetailCtrl($scope, $location, $routeParams, Wine) {
25      
27     // GET /wines/id
28     Wine.get({wineId: $routeParams.wineId}, function(wine){
29         $scope.wine = wine;
30     });
31 
32     // PUT /wines/id
33     $scope.saveWine = function () {
34         Wine.update({wineId: $routeParams.wineId},
35             $scope.wine, function() {
36             $location.path("/wines");
37         });
38     };
39 
40     //DELETE /wines/id
41     $scope.deleteWine = function () {
42         Wine.delete({wineId: $routeParams.wineId}, function() {
43             $location.path("/wines");
44          });
45     };
46 }

  service.js

1 angular.module('service', ['ngResource']).
2     factory('Wine', function($resource) {
3        return $resource('/wines/:wineId', {}, {
4            update: {method:'PUT'}
5        });
6     });

  整个项目前后端完全隔离,通过Restful协议通信;Express框架在Node.js中的地位类似于Django之于Python或Rails之于Ruby,新版Myspace是利用它开发的;Angular.js能大幅度减轻前端MVC工作量,直接进行DOM操纵而无需jQuery。
