Overview

Right now, after someone runs npx template-typescript-node-package, the create setup script will run a few commands to autofix / clean up files:

Those feel broadly useful to me for all the other two setup script forms too: initialize and migrate. Let's run the same bit of code at the end of all three of them!

Additional Info

I see that initializeWithOptions and migrateWithOptions already run a couple of those commands:

I don't know why they don't run all three 😂. This is probably a good sign that there should be a single shared function to call the three scripts. For reference, initializeGitHubRepository is another shared function that's run in all three setup scripts.

This was done... at some point.
