gql-dyn

This is a proof of concept for building GraphQL schemas dynamically using juniper.

Start

To run the project, use cargo:

cargo run

This will spin up a graphiql client, which can be accessed in your browser at http://127.0.0.1:8080

Motivation

Generating a dynamic GraphQL API based on the user's context is an advanced use case, but useful in certain scenarios. There's not a clear path on how to implement this type of customization using juniper. Thus, I wanted to explore how/if it would be possible.

Approach

This repository demonstrates one possible approach by leveraging the existing GraphQLValue::TypeInfo to provide a custom configuration during type generation. This configuration specifies which types and fields are available, and these are used to generate the final GraphQL type dynamically.
