Introduction
AWS Amplify is a development platform that provides a set of tools and services for building cloud-powered mobile and web applications. Among the many services provided by AWS Amplify is the ability to create and deploy AWS Lambda functions, which can be used to perform a variety of tasks and backend operations.
When creating a Lambda function using AWS Amplify, one of the key considerations is how the function will be triggered. Triggering a Lambda function is the process of invoking the function in response to an event, such as a file being uploaded to an S3 bucket or an API Gateway request being received. In this article, we’ll discuss how AWS Amplify manages triggers for Lambda functions and how you can use this functionality to build more powerful and efficient serverless applications.
