Code example

The lambda code has two major parts:

• main.ts - exports lambda factory. It should take all of the dependencies necessary to inject. This factory can be imported directly from tests and used to inject any mocks we need.

• index.ts - the main entry point used by webpack for production bundle generation. It takes the lambda factory from the main file, injects all necessary dependencies, and exports the ready-to-deploy handler.
