AWS AppSync JavaScript Resolver Skill

Write resolvers using the AppSync JavaScript (APPSYNC_JS) runtime. Resolvers connect GraphQL operations to data sources using familiar JavaScript syntax.

Core Pattern

Every resolver exports a request function and a response function:

export function request(ctx) {
    // Build the data source request using ctx.args, ctx.identity, ctx.source, etc.
    return { /* data source request */ };
}

export function response(ctx) {
    // Transform and return the data source response
    return ctx.result;
}
