Canduma rust Graphql

A Rust authentication server with GraphQL API, Diesel, PostgreSQL session authentication and JWT

This repository contains a GraphQL server with JWT up and running quickly.

It uses actix-web, Juniper, Diesel and jsonwebtoken

Your own pull requests are welcome!

Security

Important security considerations

We use session cookies for authentication.

Why not JWT authentication?

Stop Using JWT for sessions and why your solution doesn't work

The use of JWT remains secure only if you use adequate storage. This boilerplate is built for use in a micro-services architecture.

JWT can be use for representing claims to be transferred between two parties.

The private key should only be on this micro-service. public key can be used on all other parties to decode the token.

This boilerplate provides a complete example, so we included JWT also.

Generate RSA keys for JWT

In development mode you can keep the one in /keys folder.

// private key
$ openssl genrsa -out rs256-4096-private.rsa 4096

// public key
$ openssl rsa -in rs256-4096-private.rsa -pubout > rs256-4096-public.pem

Logging

Logging controlled by middleware::Logger actix.rs

To enable debug logging set RUST_LOG=debug in .env

Testing

Initialization

First run yarn or npm install to get all required packages

npm run test

To run you can use npm run test or yarn test.

The testing system designed to automatically build canduma offline and start in tests/jest.beforeall.js We starting canduma in order to capture output from both rust and js code using testci target

npm run testci

$ npm run testci

> canduma@ testci /home/olexiyb/b100pro/canduma
> cross-env RUST_LOG=debug DEBUG=canduma:* NODE_ENV=test jest

Determining test suites to run...
$ killall canduma

In example above you see output from jest tests as well as from rust code debug!("user_string={}", user_string);

CLion

I also highly recommend to use CLion as a dev tool. I allows to run all tests or individual with single click and analyze logs
