I'm still uneasy about things that are auto-formatting code built into the process. I would be in favor of having the script available, but not as part of the commit process.

I'm still uneasy about things that are auto-formatting code built into the process.

I'd encourage giving it a try.

Take a look at the format commit 0042254.
The code output is arguably very readable and an improvement over the existing code style, code that is written by competent, experienced, and intelligent people.
A tool like prettier can provide that highly readable code experience not just to experienced developers, but to anyone who contributes to the project, with no friction of a broken build because of code style.

I would be in favor of having the script available, but not as part of the commit process.

the npm run format command is included in this PR.
However relying on developers to manually run a formatter has proved problematic in the past.
uPortal-home's build has been broken for 4 days and counting because of a code style issue.

Does this automatically re-format to use Google's code style or does this use a separate style that we would have to match to Google's?

This version will exactly follow Google code style.
It passes code through prettier to handle graceful line breaks, then into the official Google ESLint formatter for additional tuning.

I think we can be way more open to experimental friction and risk in modules that we're less likely to need to release frequently for adoption by other teams.
widget-creator is much lower risk, in that its audience is developers.

Widget creator was suggested as a proving ground for the uPortal-app-framework team to be able to try this process out and see if its a good fit for the team dynamic.

edit corrected typos
edit 2 uPortal-home build has been fixed

Let's try it.
