For #5432 (comment)

@javiercn here's a project that's the output of these changes with individual auth: https://github.com/HaoK/Random/tree/haok/temp/reactind

I verified that things seemed to work via
dotnet run
npm run build
npm run test
npm run lint
npm run start

There are a bunch of npm audit errors related to https://npmjs.com/advisories/1677 but its not clear to me how to manually fix those (I tried explicitly installing hosted-git-info, but that didn't help, guessing its all the packages that use it that also need updating), we can do that in a follow up PR since things are working right now

Looks great! I imagine this one is much easier to update because the react template is pretty much barebones

Why not use UseReactDevelopmentServer anymore

Hi @f-nicefield-esdc. It looks like you just commented on a closed PR. The team will most probably miss it. If you'd like to bring something important up to their attention, consider filing a new issue and add enough details to build context.
