Rust + Hasura

This is an example of a Rust server that functions as a remote schema for Hasura.

It demonstrates:

• user login + signup
• JWT authorization w/ refresh cookie
• typesafe GraphQL requests
• uuid package integration

You can learn more about this stack from this talk.

Package Manager

Cargo

Setup

• Your Hasura schema must have a table user, with a id column of type uuid, and also a username column of type text.
• Set an ADMIN_SECRET and a JWT_SECRET on the graphql engine, and share these with the Rust server as environment variables.
• Use graphqurl to generate schema.json
• gq $HASURA_ENDPOINT -H "x-hasura-admin-secret: $ADMIN_SECRET" --introspect --format json > ./graphql/schema.json

Start

• cargo run
