Appsync Repo May 2026

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.

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. import { util } from '@aws-appsync/utils'; export function

In the modern cloud development landscape, building real-time applications requires a robust backend that can handle GraphQL queries, mutations, and subscriptions without forcing developers to manage servers. AWS AppSync has emerged as a leading managed GraphQL service. However, as projects scale, developers often search for the term "AppSync repo" — a concept that goes beyond a simple code repository. It represents the structured management of an AppSync project: the schema, resolvers, data sources, pipelines, and CI/CD integration. Testing Your AppSync Repo An AppSync repo without
