java sdk for OpenFGA

[udayakr]

Any plans to have java sdk for OpenFGA for integrations with spring/springboot ?

Hello @udayakr , thanks for your question. Yes, Java SDK and SpringBoot is part of our roadmap item. Please see https://github.com/orgs/openfga/projects/1/views/1 for details.

Created an issue for this under the SDK Generator for more visibility:

We have a java based micro services that needs to call OpenFGA. Saying that, I have decided to follow what Auth0 does internally and front OpenFGA with another micro-service (written in go) that gates access to Write using an OAuth2 token. OpenFGA at the moment has an all-or-nothing ApiKey approach to calling OpenFGA.

So, our JAVA SDK, isn't from OpenFGA folks at all. It's a grpc service whose proto contracts are used to create clients in all our languages (C#, go, Java, TypeScript, Python).

The only OpenFGA sdk we need is that golang one.

For now, I don't have any auth checks on READ calls, but I have locked down the Write calls into OpenFGA.

Just as an FYI, there is a Quarkus Java SDK (https://github.com/quarkiverse/quarkus-openfga-client).

It's not generated, instead it uses hand coded classes and is built on the Vert.x web client to ensure it's asynchronous and fits into the Quarkus environment.

One of the things we are looking into is replacing the web client with a client generated from gRPC that targets Quarkus/Vert.x gRPC client.

Although, the biggest issue in writing the classes by hand was the authorization model JSON classes which are quite complicated.

I'm closing this Idea since it's already in the roadmap, you can keep discussing it here openfga/roadmap#5
