Retrofit VS Feign

from this point on, I will assume, you have a basic understanding of Retrofit. To get the most out of this tutorial I would actually suggest you have a retrofit client already implemented in your application.

Now you might think that in order to make the request we are going to use Retrofit but in reality we are going to be sending out an implicit intent like so:

This particular blog post will be us building on the information from the previous blog post and using the authorization code from the GitHub OAuth API in combination with Retrofit. To finally get a access token, which allows us to make requests to the API on a behalf of a user.

Hey HN!

If you're a fan of Swift you may have noticed that with WWDC 2023 came the (beta) release of macros. They're super powerful and expressive!

I've been wishing Swift had a [Retrofit](https://square.github.io/retrofit/) style API definition library for years, and with macros it seemed like this was now possible.

I'd like to show you all Papyrus, a library that turns your APIs into type-safe Swift protocols.

Would love to get your feedback.

When it comes to consuming APIs I can definitely recommend Retrofit. Hopefully that's enough to get you started on where to look!

For Android you should use a more mobile friendly framework like Retrofit or if you use Kotlin you can use the multi-platform Ktor library with it's client module

for example https://square.github.io/retrofit/ have mentioned it in at the bottom. Similarly there maybe other rules for other dependencies. Usually I search the missing classes error in google and find some proguard rule for it.

Retrofit in combination with OkHttp for fetching data from server (which hopefully already exists)

The first get request is to retrieve a list of objects and the second one is to get a single one. You can read more about RetroFit here.

So I've been playing around with search.maven.org and perhaps I'm not quite understanding it. For example, if I look for Retrofit I'm not seeing anything that resembles retrofit above https://central.sonatype.dev/search?q=Retrofit.

A new, Feign client, to make the get request to https://example.com/themes. This client will expose a get() method.

The actual project for feign is OpenFeign https://github.com/OpenFeign/feign . Spring comes with it's own starter . Add below dependency to the project

Find a community/project that interests you, I've gone with feign. Head on into the issues tab, and you'll see all the potential contributions you could make. Starting out, it's a good idea to search for tags like "bug", or "good first issue".

Feign has support for what you're looking for. https://github.com/OpenFeign/feign/tree/master/jaxrs2

feign-spring4 gives you a type safe client proxy of an interface annotated with Spring MVC annotations.

At the risk of doxxing myself, I'm a contributer attempting to fix this issue with this pr. The project has existed for a while now, and since I'm not part of the openfeign team, so the final solution they end up using isn't up to me. So there's technical debt to deal with (how the project is built and tested currently) and whether or not multi-release jars are the best solution in this case.
