Approach B: Custom Composition with CDK

Using AWS CDK or Terraform, you can write a synthesis step that: Canonical GraphQL schema files

A unified repository for AppSync addresses these challenges by providing a single source of truth for all related code. Benefits include:

// Inline resolvers (stored as assets) api.createResolver('QueryGetPostJS', typeName: 'Query', fieldName: 'getPost', code: Code.fromAsset(path.join(__dirname, 'resolvers/Query.getPost.js')), runtime: FunctionRuntime.JS_1_0_0, );

export function request(ctx) return get( key: id: ctx.args.id );
