Best practices for AWS AppSync GraphQL APIs

The article discusses best practices for building GraphQL APIs using AWS AppSync, covering security, performance, coding standards, and deployment.

Specifically, the article covers:

• Security best practices, including authentication methods (OIDC, Cognito User Pools, API keys, etc.) and secrets management
• Performance best practices, such as caching at the resolver level or data source level (e.g., DynamoDB Accelerator)
• Coding best practices, like using pipeline resolvers instead of unit resolvers, leveraging native resolvers, and preferring JavaScript over Apache VTL for resolvers
• Deployment best practices, including using AWS Amplify for CI/CD pipelines, Infrastructure as Code with AWS CDK, and choosing between the native AWS AppSync CDK construct or the Amplify API CDK construct
