The Angel Framework/discussion

General discussion about the Angel framework.

I'm working on a small app project that will involve file uploads, so I'm going to experiment with it on my end. I might open an issue to see if people want support for it.

Tobe Osakwe

@thosakwe

This spec is what I'd be looking at: https://github.com/jaydenseric/graphql-multipart-request-spec

Quick look

Tobe Osakwe

@thosakwe

Spitballing here, but server side rendering of flutter_web would be awesome. Not sure if it’s necessarily even possible

@RandalSchwartz

I think it has come up a few times. Might even be a github issue on it

Tobe Osakwe

@thosakwe

I’d bet. I remember seeing people ask about it for AngularDart, so not surprised

Some cool stuff happening in: https://github.com/angel-dart/security/tree/master/example

can you guys help me with this
related to "dart:io"

I want to call stdout.flush but it throws an error
I can't find solid solution ...

Hi, Tobe and everyone! So, I've just started to develop with Angel and I'm reading through the docs, but I can't figure it out how do I specify the Response status code, any thoughts?

@pedrospj

Thx, Tobe, Angel's awesome, keep doing the great job

Tobe Osakwe

@thosakwe

Thanks!!!

Hi, Tobe, for generating migration, I should write the driver as in:
https://docs.angel-dart.dev/v/2.x/orm/migrations#running-migrations
Not like as in Laravel, just type the command?

under <project>/bin?

Yarco

@yarcowang

Hi, is there any tutorial for GraphQL+User Auth+ DB Migration? ( I'm wondering whether they are in experimental or production?)

I feel it is not very clear even I know laravel/express when first-time taste dart/webserver~

Tobe Osakwe

@thosakwe

Correct, you should write the driver file for migrations

There’s no tutorial specifically for that combination, but there are docs for each of those things separately

Yarco

@yarcowang

Not quite sure I'm on the right way~ it responses nothing.

Tobe Osakwe

@thosakwe

You’re not actually running the migrations, you’ve just created a MigrationRunner instance

You need to add a call to “runMigrations(migrationRunner, args)”

You can then run commands like “migrate.dart up” or “migrate.dart —help”

Yarco

@yarcowang

Does any tutorial or doc anywhere relate to this topic? For I can see only https://docs.angel-dart.dev/v/2.x/orm/migrations this page.

Tobe Osakwe

@thosakwe

Each Angel package has a Github repo with additional documentation +examples

Though that page could definitely be improved!

https://github.com/angel-dart/orm/blob/master/angel_migration_runner/example/main.dart

Yarco

@yarcowang

I understand ;) When we do more codes, we are lazy on the doc, and you already did the perfect thing.

Yarco

@yarcowang

@thosakwe Is there any way to list services somehow? Or also objects in the app's container? (Like in Symfony?)

Or also routes ( I mean get informations ) , like artisan route:list

Yarco

@yarcowang

I feel I'm facing black box when deal with Dart, ex.: I can run pub run, but there's no list command to list sub-commands.

Tobe Osakwe

@thosakwe

It may be worth it for you to read the Dartdoc entries for Angel, as all of these functions are also documented there

https://pub.dev/documentation/angel_framework/latest/

List all services: https://pub.dev/documentation/angel_framework/latest/angel_framework/Routable/services.html

Dump the route tree: https://pub.dev/documentation/angel_framework/latest/angel_framework/Angel/dumpTree.html

There’s no way to list things in the app container at this point, as it wasn’t necessary at the time. But if that’s something you’re interested in, send a pull request to angel-dart/container on GitHub

Yarco

@yarcowang

Does there exist staging in Angel initializing process? ex.: Angel app(staging:'RouteLoaded'), I think then it will be quite easy for outputing the route tree.

Tobe Osakwe

@thosakwe

Why not just call app.dumpTree if app.environment.isStaging?

Yarco

@yarcowang

You are right. But I think maybe the initializing process is complicated, and people want to stop at some points.

Tobe Osakwe

@thosakwe

Where might you want to stop?

Yarco

@yarcowang

For example, with or without Database connection

But maybe it is hard to make the decision for asynchronous application. Not quite sure.

Yarco

@yarcowang

Hi, Tobe, I'm trying to add a middleware to the service,

class RegisterService extends Service<String, Map<String, dynamic>> {
  @Middleware(const [requireAuthentication<User>()])
  FutureOr<Map<String, dynamic>> getVerificationCode(Map<String, dynamic> data, [Map<String, dynamic> params]) {

but IntelliJ Idea tells me

error: The values in a const list literal must be constants. (non_constant_list_element at [hello] lib/src/services/register.dart:9)
error: Arguments of a constant creation must be constant expressions. (const_with_non_constant_argument at [hello] lib/src/services/register.dart:9)

And even I remove const keyword, the errror still exist... Running the script returns:

lib/src/services/register.dart:9:22: Error: Method invocation is not a constant expression.
  @Middleware(const [requireAuthentication<User>()])
                     ^^^^^^^^^^^^^^^^^^^^^

Don't know how to solve that.

Yarco

@yarcowang

Em... Does it mean those handlers are at compile time??

Yarco

@yarcowang

Envoloping it seems working:

FutureOr<bool> _auth(RequestContext req, ResponseContext res) async {
  return Future.value(requireAuthentication<User>()(req, res) as bool);
}

But seems not a good solution.
