I was reading the doc and learned that React StrictMode is for development only, and it explains why we have double invoke.

That's great, but does it mean I have to disable the StrictMode manualy for my production, or does react build command does it on its own?

Stright from the Beta docs:

Strict Mode enables the following checks in development:

• Your components will re-render an extra time to find bugs caused by impure rendering.
• Your components will re-run Effects an extra time to find bugs caused by missing Effect cleanup.
• Your components will be checked for usage of deprecated APIs.

All of these checks are development-only and do not impact the production build.
