Prerequisites

To integrate with AWS Cognito, you will need the following environment variables in the root of your project.

COGNITO_USER_POOL_ID=
AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=

Create the Cognito User Entity

Use the createAwsCognitoUserResolver to create a CognitoUser resolver using the environment variables described above.

in backend/cognito/index.ts

export const cognitoUser = createAwsCognitoUserResolver({
		userPoolId: process.env.COGNITO_USER_POOL_ID,
		region: process.env.AWS_DEFAULT_REGION,
	});

createAwsCognitoUserResolver returns an object that contains a resolver, an entity, and a provider for AWS Cognito.

The resolver must be added to your Graphweaver resolvers:

backend/schema/index.ts

import { cognitoUser } from '../cognito';

export const resolvers = [cognitoUser.resolver];

backend/index.ts

import { resolvers } from './schema';

const graphweaver = new Graphweaver<AuthorizationContext>({
	resolvers,
});

export const handler = graphweaver.handler();
