Sebastian Muller wrote this article / tutorial about AWS AppSync, a serverless GraphQL with support for custom data sources using AWS Lambda. To enable easy access to his RSS feed, author created a simple GraphQL API using AWS AppSync.
Tricky part was the deployment of the API due to lack of CloudFormation support for AWS AppSync. In the tutorial, you will find:
- AWS Lambda function to fetch and parse RSS feed
- Serverless Application Model to deploy Lambda function
- AppSync GraphQL API setup using AWS CLI
Tutorial then describes in detail what dependencies are, how to install Golang packages, configure environment and deploy using AWS Serverless Application Model. And finally you will learn how to use the GraphQL API. Great article!
