Elixir Helpers for Seamless Pipelines

In Elixir, code is often designed to work seamlessly with pipelines, but sometimes developers encounter breaks that disrupt the flow. This article presents two helpful functions, `then` and `tap`, which can be used to intervene in a pipeline without breaking it. Using a `conn` pipeline as an example, it demonstrates how to inspect a flash assign using `dbg` without stopping the pipeline flow. `then` is a function that lets you perform an operation and continue passing the modified value down the pipeline, while `tap` lets you perform a side-effect without changing the returned value. These functions are beneficial when you need to debug or interact with the data within a pipeline but want to maintain a clean and uninterrupted flow of data.
