We use
babelCore.loadPartialConfig
in Parcel and noticed that after creating a.babelrc
in a directory where non previously existed, this config was not picked up without restarting the process. This was due to Babel caching the fact that the file did not exist indefinitely. This is not a safe assumption, as the user can create a config file without restarting the process. Always checking the mtime should do the trick.Happy to add a test if someone can point me to a good place to do it. 😄
