Do you enforce Prettier in all Next.js projects?

I’ve been working mostly with Next.js projects recently and noticed that some teams treat Prettier as non-negotiable, while others skip it entirely and rely on ESLint rules or manual formatting.

I’m curious how people here approach this in real projects.

Do you: - enforce Prettier strictly in CI? - allow developers to format however they want? - use something else instead? - skip formatting tools entirely?

Has Prettier ever caused friction in your workflow or improved team velocity?
