Rust + Axum + Prisma

A template for creating services in Rust using Axum and Prisma. This uses the super cool Prisma Rust Client.

Getting Started

You'll want to have cargo-watch installed for the best DX, however it isn't required.

cargo install cargo-watch

Then you can run the cargo-watch -x run command to watch for changes and automatically rebuild the project.

Prisma

To set up prisma, run:

cargo prisma generate # outputs client to src/prisma.rs
cargo prisma db push # outputs sqlite db to prisma/dev.db (specified in schema.prisma)
cargo seed # seeds the database with some data (unimplemented, create a seed based on your needs)

For more in-depth information about the prisma client, see the Prisma Client Rust Docs.

Run the Server

To run the server, run:

cargo run # or cargo-watch -x run

GraphQL Playground

Go to localhost:8080/api/graphql to see the playground. You can see the schema and the docs, but a few examples would be:

# Create user
mutation {
  createUser(input: { displayName: "oromei" }) {
    id
  }
}

# Create post
mutation {
  createPost(
    input: {
      content: "Woah there!"
      userId: "5ab80953-c38c-4ec8-8b4b-3ecc4bc1196f"
    }
  ) {
    id
    content
    user {
      displayName
    }
  }
}

# Get all users
query {
  getUsers {
    id
    displayName
  }
}

# Get all posts
query {
  getPosts {
    id
    content
    user {
      displayName
    }
  }
}

Notes

This template uses Axum, but the bulk of the setup is for async_graphql + prisma. You should be able to easily swap out Axum for your preferred framework (e.g. Rocket, actix, etc).

The simple use of async_graphql means that queries are done in a less efficient manner than could be, since fetching relations using with is never utilized and relations are loaded separately. Additionally, dataloader is not utilized because I can't be bothered.
