Rusty Todos 🦀

A fun little experiment to help me brush up on my Rust.

This is a simple little GraphQL ToDo Api built with:

• Rust (obviously)
• Async Graphql
• AWS Lambda (via SAM and cargo-lambda)
• DynamoDB
• serde_dynamo 🙂

Schema:

type CompleteResult {
        username: String!
        task: String!
}

type Mutation {
        addTodo(username: String!, task: String!): Todo!
        markTodoComplete(username: String!, task: String!): CompleteResult!
}

type Query {
        user(username: String!): User!
        users: [User!]!
}

type Todo {
        task: String!
        completed: Boolean!
}

type User {
        username: String!
        todos: [Todo!]!
}

schema {
        query: Query
        mutation: Mutation
}

To Deploy to a test AWS Account 📦

1. Make sure you have an aws profile configured via: aws configure (You will need access creds configured on your profile).
2. In the root of this repo: sam build
3. sam deploy (Follow the prompts)
4. Query Away

If I have Time:

• Refactor the graphql error handling to not be a hack... 🙈
• Learn the best way to unit test this kind of code 🧪
• Learn about better dependency injection practices with Rust 🏗️
