Set Up a GraphQL API with AWS AppSync and Amazon Aurora Serverless

This use case is a simple demo that shows how to create a GraphQL API using AWS AppSync and an Amazon Aurora Serverless database as the data source.

Customizing the Demo

Change the values for the variables in the variables.tf file to customize the demo (for example, region, database name, etc.).

Accessing the API

After the apply command is run without errors, you should be able to access the API via the AppSync console. The console will show the URL for the GraphQL endpoint, which includes an API named roles-api. You can also access and invoke the API using the AWS CLI, the AWS SDKs, etc.

Example queries, mutations, and subscriptions to interact with the API:

mutation MyMutation1 {
    createRole(id: "3", name: "ROLE NAME") {
        id
        name
        description
    }
    updateRole(id: "3", name: "DUMMY_USER", description: "Dummy User") {
        id
        name
        description
    }
}

query Query {
    listRoles {
        id
        name
        description
    }
}

mutation MyMutation2 {
    deleteRole(id: "3") {
        id
    }
}

subscription MySubscription {
    onDeleteRole {
        id
        name
        description
    }
}

API Schema and Resolvers

The schema and resolvers for the API are defined in the schema file and resolvers directory, respectively.
