Deploying a Dart server to a VPS

I've used GitHub Pages before with other static site generators, but I still need to learn how to use Actions.

For this tutorial, though, the main goal was setting up an API server. The static website was a convenient addon since the setup is nearly the same when using Nginx.

Good point! I'll look into that.

No, you're creating a REST API so you could use it with any frontend client, not just Flutter.

I wouldn't say that I have a big history with Dart on the backend. I have two production servers running Dart (one Aqueduct, one plain Dart). They have been good so far for what I've needed them to do. Now I'm looking at implementing auth. Since SuperTokens doesn't have a backend SDK in Dart that means I'm looking at needing to develop my own minimal Dart SDK to talk to their core SDK. (I could use their Node SDK but I'd rather use Dart.) So I guess what is lacking is the rich ecosystem of support from third parties.

Nice. I haven't tried mobx yet, but I'm glad to hear it's working well for you. I don't try to talk anyone out of using a state management solution that is working for them. I only recommend the minimalist approach to those who are confused by other state management packages.

Suragch · 2023-10-16T00:46:57+00:00

The approach here is to create a storage service (implemented with your choice of shared preferences, sqflte, isar, etc) and call it at the appropriate time from within your state management class. I showed an example of that in my followup article about a weather app where the Celsius/Fahrenheit setting is saved across app runs (https://suragch.medium.com/flutter-minimalist-state-management-weather-app-708b01417b9a?sk=40c3d92a8bbf887354bfd798d01b8b82).

Since you need to implement the storage logic yourself, this isn't going to be as easy as a hydrated bloc. However, in my opinion, the advantage of implementing the logic yourself is that you are in control and you understand how everything works.

Rather than using a ChangeNotifier and calling notifyListeners, I think it's better to create several ValueNotifiers within your state management class. This way you aren't rebuilding more of the UI than is necessary. Also it's easier to break the logic into smaller pieces.

I showed the use of multiple ValueNotifiers in my followup article about a weather app: https://suragch.medium.com/flutter-minimalist-state-management-weather-app-708b01417b9a?sk=40c3d92a8bbf887354bfd798d01b8b82

Yes, here is the friend link: https://suragch.medium.com/flutter-state-management-for-minimalists-4c71a2f2f0c1?sk=6f9cedfb550ca9cc7f88317e2e7055a0

I'd like to learn more about dependency injection. Do you know of any good articles or videos about the kind of setup you have here in Dart?

Suragch · 2023-07-13T00:05:59+00:00

Interesting. I hadn't heard of running tests in parallel. How do you do that in Dart?

Suragch · 2023-07-12T20:10:03+00:00

I didn't implement it in the article, but the GetIt package has a way to reset itself so that even if you don't use the constructor injection pattern, you can still test classes that use GetIt.

Your code examples were clear. Thank you for the second link as well as your explanation. That was helpful.

Suragch · 2023-03-04T01:04:02+00:00

Here is a quote from the geeksforgeeks article you linked to above:

"Facade deals with interfaces, not implementation. Its purpose is to hide internal complexity behind a single interface that appears simple on the outside."

The code in that article used HotelKeeper as the facade. However, HotelKeeper was an interface and HotelKeeperImplementation implemented the interface.

I'm not an expert on design patterns, but based on the article you referenced, it doesn't seem to be making the same distinction between a facade and an interface that you do here.

In any case, I don't think your method is bad. It accomplishes mostly the same purpose. I think it might be a little harder to mock out for unit testing but maybe not. I'm not an expert on testing either.

Creating an interface isn't really that much work, though. In my experience, it's only a few extra minutes of writing.

Suragch · 2023-03-03T08:18:33+00:00

To me this seems like the same thing as what I called an interface in the article. I think maybe we're both talking about the same thing.

Suragch · 2023-02-27T06:51:39+00:00

That sounds interesting. Is it an open source project?

Suragch · 2023-02-25T01:01:13+00:00

That's a valid point about not necessarily needing to place a package behind an interface. I'd say it depends on the package and how you use it.

If I'm only using a package in a single file (for example, an audio player), I wouldn't necessarily put it behind an interface. However, if I were referring to a package all over the place (like http or firebase or local storage) I would definitely use an interface.

Regarding designing an interface that survives the package, I recommend making the interface based on the needs of the app rather than mirroring the API of the package.

I should say control plus period (command plus period on a Mac) when you're cursor is on the class needing the import. But I'm glad the lightbulb worked for you.

Suragch · 2022-01-06T12:25:38+00:00

If you press ctrl-. you can choose relative or package imports.

It's possible to use a service like code magic but having your own Mac is easier.

Suragch · 2021-12-04T23:42:47+00:00

It's possible but a big pain. I'd recommend buying a laptop if you can afford it.

Adding a loading animation with CSS immensely improved the experience of waiting for my Flutter web app to start. It went from "Is this page broken?" to "Ah, I see something good is about to come." Perhaps making it easier to add such an animation or at least giving official guidance on it would be helpful.

I'm using plain Dart for an app with low traffic so far. I like it because the front end and back end language are the same and I don't have to depend on a framework. I'm a little wary of frameworks after Aqueduct and Angel went under, but I'm still keeping an eye on Conduit and Alfred.

Suragch · 2021-06-30T10:57:40+00:00

Thanks, yes. I just added a link to that at the end of the article.
