• Expose flag to disable "duplicate atom key" checking / logging, as it was too noisy in environments such as NextJS or some dev environments using Fast Refresh. (#733, #2020, #2046)
  • Import RecoilEnv from the recoil package, and set RecoilEnv.RECOIL_DUPLICATE_ATOM_KEY_CHECKING_ENABLED = false in code to disable the checking and logging.
  • We also support process.env.RECOIL_DUPLICATE_ATOM_KEY_CHECKING_ENABLED=false in NodeJS environments such as NextJs
  • Caution: This disables all checks for duplicate atom keys including legitimate errors, so use with caution!
• Workaround for React 18 environments with nested renderers that don't support useSyncExternalStore(). (#2001, #2010)
