Dart Force MVC

LOGO!

Part of the Dart Force Framework.

Serverside MVC based implementation for Dart. Easy to setup and part of the dart force framework!

Remark

We changed the name of WebServer to WebApplication! ForceMVC can now also be used on Google AppEngine.

Walkthrough

Use a Web Application Server with dart very easily, create controllers with annotations ... similar to spring mvc.

First you will setup a new web application.

WebApplication app = new WebApplication(wsPath: wsPath, port: port, host: host, buildPath: buildPath);

Then you use the 'use' method to handle http requests.

app.use(url, (ForceRequest req, Model model) { /* logic */ }, method: "GET");

You can also use the annotation RequestMapping in a dart object

@RequestMapping(value: "/someurl", method: "GET")
void index(ForceRequest req, Model model)

You can also use the annotation @ModelAttribute to add an object to all the scopes in the methods. An @ModelAttribute on a method argument indicates the argument should be retrieved from the model. If not present in the model, the argument should be instantiated first and then added to the model. Once present in the model, the argument's fields should be populated from all request parameters that have matching names.

@ModelAttribute("someValue")
String someName() {
	return mv.getValue();
}

Then you register that object on the WebApplication object.

app.register(someObjectWithRequestMappingAnnotations)

Or you can annotate a class with @Controller and then it will be registered automatically in the force WebApplication.

@Controller
class SomeObject {

}

Starting your web application

You can do this as follow!

app.start();

It is also possible to start a web application with SSL possibilities.

app.startSecure();

ForceRequest

ForceRequest is an extension for HttpRequest

forceRequest.postData().then((data) => print(data));

Interceptors

You can define inteceptors as follow, the framework will pick up all the HandlerInterceptor classes or implementations.

class RandomInterceptor implements HandlerInterceptor {

  bool preHandle(ForceRequest req, Model model, Object handler) { return true; }
  void postHandle(ForceRequest req, Model model, Object handler) {}
  void afterCompletion(ForceRequest req, Model model, Object handler) {}
  
}

Path variables

You can now use path variables in force mvc.

@RequestMapping(value: "/var/{var1}/other/{var2}/", method: "GET")
void pathvariable(ForceRequest req, Model model, String var1, String var2)

This is an alternative way how you can access path variables.

req.path_variables['var1']

You can also use the annotation @PathVariable("name") to match the pathvariable, like below:

  @RequestMapping(value: "/var/{var1}/", method: "GET")
  String multivariable(req, Model model, @PathVariable("var1") variable) {}

Redirect

You can instead of returning a view name, performing a redirect as follow:

@RequestMapping(value: "/redirect/")
String redirect(req, Model model) {
	redirect++;
	return "redirect:/viewable/";
}

Asynchronous Controller

In the controller you can have asynchronous methods to handle for example POST methods much easier.

On the ForceRequest object you have a method .async and his value is the return value that matters for the req.

When a method is asynchrounous you must return req.asyncFuture.

This is an example how you can use it.

@RequestMapping(value: "/post/", method: "POST")
Future countMethod(req, Model model) {
     req.getPostParams().then((map) {
       model.addAttribute("email", map["email"]);
       
       req.async(null);
     });
     model.addAttribute("status", "ok");
     
     return req.asyncFuture;
}

Authentication

You can now add the annotation @Authentication to a controller class. This will make it necessary to for a user to authenticate before accessing these resources.

An authentication in force is following a strategy. You can set a strategy by extending the class SecurityStrategy.

class SessionStrategy extends SecurityStrategy {
  
  bool checkAuthorization(HttpRequest req, {data: null}) {
    HttpSession session = req.session;
    return (session["user"]!=null);
  }   
  
  Uri getRedirectUri(HttpRequest req) {
    var referer = req.uri.toString();
    return Uri.parse("/login/?referer=$referer");
  }
} 

And then add this strategy to the web application.

app.strategy = new SessionStrategy();

Roles

You can also define authorize roles. This can be done as follow.

@Controller @PreAuthorizeRoles(const ["ADMIN"]) class AdminController {

}

ExceptionHandler

This helps in defining methods that will be executed when an error or exception occured.

@ExceptionHandler()
String error_catch(req, Model model) {
	...
}

You can also specify a type, only when an error or exception happend of that Type, that method will be executed.

@ExceptionHandler(type: DoorLockedError)
String doorLockedError(req, Model model) {
	model.addAttribute("explanation", "This is a specific error!");
	return "error";  
}

Logging

You can easily boostrap logging.

app.setupConsoleLog();

Wired

Wired is a dependency injection package. You can use @Autowired and @bean and more in forcemvc find info here

LocaleResolver

In ForceMVC you have a locale resolver to handle locale. The implementation that is been used by default is the AcceptHeaderLocale Resolver, this resolver looks at the request header accept-language.

You can choose for a fixed locale resolver implementation or a cookie locale resolver or just implement your own handling if need.

Development trick

Following the next steps will make it easier for you to develop, this allows you to adapt clientside files and immidiatly see results with doing a pub build.

pub serve web --hostname 0.0.0.0 --port 7777 &&
export DART_PUB_SERVE="http://localhost:7777" &&
pub run bin/server.dart

Example

You can find a simple example with a page counter implementation here - live demo

TODO

  • get more annotations and options for sending the response back
  • writing tests

Changelog

This file contains highlights of what changes on each version of the forcemvc package.
