diana = "0.2.9"

A while ago, I was thinking about how to get serverless GraphQL working with subscriptions. Unfortunately, you can't easily, because subscriptions are state*ful*, and so they have to be run on a server*ful* system. But there's nothing to stop a serverful subscriptions system from being connected to a serverless queries/mutations system!

Diana is a GraphQL system for Rust that does just this. It's mostly a high-level wrapper around the excellent work of async_graphql, but it adds authentication and a bridge between serverful and serverless systems.

Right now, Diana supports integration with Actix Web and AWS Lambda (including derivatives like Netlify) out of the box, with support for more platforms coming soon! You can read Diana's documentation in the book.

Installation

You can easily install Diana by adding this to your Cargo.toml under [dependencies]:

diana = "0.2.3"

All Diana's integrations (currently diana-actix-web and diana-aws-lambda) are kept to the same version as the core library, so everything is always at the same version.

Usage

Diana is pretty easy to use, just define your configuration and set up the integration and you're good to go, with authentication built-in! There's more on how to do this in the docs here.

Closing Words

I've found Diana to be really useful so far for simplifying GraphQL in my own projects, so I hope it helps someone! Please open an issue on the repository if you find a bug or want to propose a new feature!
