Resolver tutorials (JavaScript)
Data sources and resolvers are how Amazon AppSync translates GraphQL requests and fetches information from your Amazon resources. Amazon AppSync has support for automatic provisioning and connections with certain data source types. Amazon AppSync supports Amazon Lambda, Amazon DynamoDB, relational databases (Amazon Aurora Serverless), Amazon OpenSearch Service, and HTTP endpoints as data sources. You can use a GraphQL API with your existing Amazon resources or build data sources and resolvers. This section takes you through this process in a series of tutorials for better understanding how the details work and tuning options.
