### Working Directory for Scripts

Scripts are always run from the root of the package folder, regardless of what the current working directory is when `npm` is invoked. This means your scripts can reliably assume they are running in the package root.

If you want your script to behave differently based on the directory you were in when you ran `npm`, you can use the `INIT_CWD` environment variable, which holds the full path you were in when you ran `npm run`.

#### Historical Behavior in Older npm Versions

For npm v6 and earlier, scripts were generally run from the root of the package, but there were rare cases and bugs in older versions where this was not guaranteed. If your package must support very old npm versions, you may wish to add a safeguard in your scripts (for example, by checking process.cwd()).
