This blog is part 4 of the “Getting started with serverless for developers” series, helping developers start building serverless applications from their IDE. Many “getting started” guides demonstrate how to build serverless applications from within the AWS Management Console. However, most developers spend the majority of their time building from within their local integrated development […]
