Building REST-based services is pretty common when it comes to the backend world. When it comes to developing the service in a serverless world, it's a trend, but it comes with a lot of pain. For instance, we need to write a function in the language of our choice, then need to build a provisioning script like cloud formation or terraform to chain the set of services used for building the solution.
In this article, we will be building a REST-based service on AWS lambda, API gateway, and PostgreSQL database. The key part is that we will be developing it completely using a low code integration tooling and runtime framework, Kumologica.
