Compile TypeScript code to AWS "Functionless" Step Functions and Event Bridge Pipes

Functionless is an attempt to compile TypeScript code into AWS "Functionless" definitions (e.g. Step Functions or Event Bridge Pipes).

It primarily focused on transforming a TypeScript function into an AWS Step Function workflow definition, but Step Functions weren't Turing Complete (lacked JSONAta back then), so ultimately failed.

import { StepFunction } from "@functionless/aws-stepfunctions";

import MyDatabase from "./table";

export default StepFunction(async (input: { todoId: string }) => {
  await StepFunction.waitSeconds(10);

  await MyDatabase.attributes.delete({
    Key: {
      pk: {
        S: "todo",
      },
      sk: {
        S: input.todoId,
      },
    },
  });
});

The lesson learned from this project is to find solutions that don't necessitate static analysis and compiler tools. "Don't fight your language".
