rust-graphql-docker's Introduction

Dockerize Graphql Rust

More current version at https://github.com/jayy-lmao/rust-cult-graphql-server

This project is currently for demonstrating the use of dataloaders in a rust-based graphql server. This demo uses:

actix-web a high-performance webserver for rust https://www.techempower.com/benchmarks/
juniper a popular rust graphql framework https://github.com/graphql-rust/juniper
A dockerfile which creates a from scratch minimal sized container
Cults (more to be added)

There are definitely some improvements to be made in db requests, pagination etc. Let me know if you spot anything you think is top-priority!

Running locally

simple as docker-compose up, crazy! Then navigate to http://localhost:8000/graphql

TODO

Schema

type Cult {
  id: Int!
  name: String!
  members: [Person!]!
}

type Mutation {
  createPerson(data: NewPerson!): Person!
  createCult(data: NewCult!): Cult!
}

input NewCult {
  name: String!
}

input NewPerson {
  name: String!
  cult: Int
}

type Person {
  id: Int!
  name: String!
  cult: Cult
}

type Query {
  personById(id: Int!): Person!
  persons: [Person!]!
  cultById(id: Int!): Cult!
  cults: [Cult!]!
}

Missing DB column error for cults query

There's a missing column issue with the db. Not sure what changed, but will have to go fix it.
