Appsync Repo -

const table = new dynamodb.Table(this, 'ItemsTable', { ... }); const dataSource = api.addDynamoDbDataSource('ItemsDS', table);

import { util } from '@aws-appsync/utils'; export function request(ctx) { const userId = ctx.identity.claims.sub; return { operation: 'GetItem', key: { id: ctx.args.id, userId } }; } Store subscription resolvers separately. Use @aws_subscribe directives in your schema to link mutations to subscriptions. Your repo should include directives. Testing Your AppSync Repo An AppSync repo without tests is risky. Implement three layers: Unit Tests (Jest + @aws-appsync/utils ) Test resolver logic without AWS infrastructure. appsync repo

Start today: create a new GitHub repository, initialize a CDK app, add your schema.graphql , write one resolver, and deploy it. Once you have that working, expand with data sources, pipelines, and real-time subscriptions. Your future self — and your team — will thank you. const table = new dynamodb

An AppSync repo is not just about storing code; it is about treating your GraphQL API as a first-class, version-controlled, testable, and automatable component of your cloud architecture.
