The Angel Framework/discussion

General discussion about the Angel framework.

Then by calling container.make<Repository>(), it will automatically insert the correct arguments

You just need to have a QueryExecutor singleton before creating the Repository instance

I just realized that the demo file doesn't have an example of this. But that is how Angel.mountController works

By saying, "using dart:mirrors (or reflectable)", you mean the "reflector" parameter in var app = Angel(logger: logger, reflector: MirrorsReflector()); ?

Tobe Osakwe

@thosakwe

Yes

Omar BELKHODJA

@omarbelkhodja

OK, thanks. I will give it a try then :)

Tobe Osakwe

@thosakwe

But if you are in a situation where you cannot use dart:mirrors, there is angel_container_generator. It is currently undocumented.

Omar BELKHODJA

@omarbelkhodja

I think, what you explained now, is writen here https://docs.angel-dart.dev/v/2.x/guides/dependency-injection#in-routes-and-controllers

@omarbelkhodja

But I didn't really understand it, before your explanations now.

Sorry, the correct link is https://docs.angel-dart.dev/v/2.x/guides/dependency-injection#dependency-injected-controllers

I see the annotation @contained in the test file. Is it mandatory ?

Tobe Osakwe

@thosakwe

The documentation is needing improvement. At the time I wrote it, things made sense to me, but now I see that certain fundamental things are mostly glossed over, or not touched upon in full depth.

Yes, you will need @contained. There's also GlobalQuanityCapability, which you may need.

@contained is a specific constant Reflectable object. With package:reflectable, you need to use it as an annotation on any class you want to build reflection for

Ultimately, it's not super convenient, plus reflectable cannot properly reflect functions, so mirrors is preferable

In situations where you absolutely must use AOT, you can still use the container, as the core singleton/factory mechanism doesn't use reflection, but things will get more verbose

The ioc top level function does basically the same thing as controller methods - it uses the provided reflector to inject arguments into a function

Omar BELKHODJA

@omarbelkhodja

What I did right now : created the new MyRepository class, as described in the test file, with the executor as a parameter of the constructor, also added MyRepository as a parameter in the MyController class, and used await app.mountController<MyController>();

Using breakpoints, I can see that MyRepository and MyController instances are created

But the problem now, is that MyController is not handling HTTP requests anymore.

Any idea why ?

Before that, I was using app.configure(MyController().configureServer);

Omar BELKHODJA

@omarbelkhodja

Sorry, I think it is a mistake of mine : I have other routes, not in the controller, that was leading to a misbehavior in the routing.

@thosakwe

Ah ok

Hello guys! Does Angel have template engine? Or best practice use AngularDart for front-end? I'm newer in Dart)

Tobe Osakwe

@thosakwe

Yes, it's called Jael :) https://github.com/angel-dart/angel/tree/master/packages/jael

Docs: https://docs.angel-dart.dev/packages/front-end/jael

@lobanovkirill

Wow!) Thank you for your fast answer!)))

Hmmmm... This link in documentation not working https://dart.academy/using-angel-with-angular2/

Fix this or maybe delete

Tobe Osakwe

@thosakwe

I don't have access to that site, maybe the article was deleted or the site format changed

It looks like dart.academy itself is no longer up

Tobe Osakwe

@thosakwe

Forgot this existed, but the predecessor to Angel: https://github.com/korat-dart/korat_framework

Kirill

@lobanovkirill

Interesting) I can build real-time app in Angel?🤔🙂

Tobe Osakwe

@thosakwe

Sorry for the inactivity - exam season

@lobanovkirill

Good luck in exams!)))

Hello guys,I have a question about ORM.

Tobe Osakwe

@thosakwe

Ask away

zulin

@llinzzi

How to define the model file， whith the case in User & User . Like the frinds of some user.

@thosakwe thank you for the great job, I love angel-dart framework.

Devin Moure

@DevinM4

@serializable
abstract class _User extends Model  {
  @ManyToMany(_Friends)
  List<_User> get users;
}

@orm
@serializable
abstract class _Friends {
    @belongsTo
    _User get user;
}

@llinzzi try

@DevinM4 Thank you

Hello! Im interested in working with Angel-Dart. Im a little confused though, do you install it on an actual server and then have the app (client) communicate with it? Or does Angel-Dart just run a virtual server in the background for local storage? I guess what Im saying is, should I use Angel-Dart for a chat app where people can communicate with others?

Tobe Osakwe

@thosakwe

Angel is ultimately just a set of libraries (though you can get away with just using package:angel_framework). You'll install dart on a Web server, and after doing that, use pub get to install dependencies onto the server. Lastly, you'll need some sort of "executable" Dart file (typically named bin/main.dart or similar) that can be run in the background as a persistent task.

You don't necessarily have to run it in the background, though. While developing locally, you'll typically just run the executable file directly in a terminal.

Yes, you can use Angel for a chat app. You can use it for any kind of HTTP server at this point.

That’s awesome! Thanks for quick reply! @thosakwe
