+title: Set package-level Prettier configuration
+description: Keep the project's root folder clean from extra configuration files while enforcing an organization-wide codestyle.

+By setting the Prettier configuration directly in `package.json`, you avoid both the issue of saturating your workspace's root folder with another config file as well as arguably more importantly also completely eliminating inconsistencies in Prettier rules between projects.
