🔎 Overview

Fixes #4047

  • Added validation to the file(s) passed in to the --file option by resolving the argument to an absolute path and check for its existence. We now log a warning and exit if the file does not exist.
    • the errors for --require bubble up to the middleware in lib/cli/run.js. See here. This specific error occurs in lib/cli/run-helpers.js in the singleRun method when we load files asynchronously. Since we were lacking error handling there, the errors appeared the way they previously did before these changes.
  • Added a test to assert our changes

Screenshot from 2024-02-07 00-34-30

- added error handling when using the --file flag to do it the way
  --require does
- added a test to assert that we throw the same type of error

- require.resolve() by Node.js follows a Node.js module resolution algo
  which includes checking if the resolved path actually exists on the
  file system.

Cool! 😎

Requesting changes on adding a bit more testing. But also let's talk about the direction a bit - I feel nervous adding in process.exit/throws deep within code. Thanks for sending!
