I am using the serverless appsync plugin to generate a full appsync app. I just want a lambda function as my datasource (no dynamoDB or elastic search). The plugin does indeed create the appSync API with graphQL and resolving template. There is even a link to a Lamba function in AWS AppSync > myApi > Data Sources , but the actualy Lambda function isn’t present in the AWS Lambda console. See my github issue for more github issue
