`prettier-plugin-xquery` adds XQuery support to the Prettier code‑formatter, letting developers automatically format XQuery and XQuery‑Update files with the same opinionated style options (tabs, print width, quotes, etc.) that Prettier provides for other languages. It’s aimed at XQuery programmers who want consistent, editor‑agnostic formatting—especially those using tools like ExistDB or MarkLogic—by installing the npm package and configuring it in a Prettier setup.
