prettier-plugin-compactify

library0.1.6jsnpmunverified

A Prettier plugin that preprocesses JavaScript/TypeScript code to collapse object literals into compact single-line formatting. Version 0.1.6, actively maintained but early-stage. Unlike other Prettier plugins, it hooks into the parsing stage to enforce compact object notation, addressing a long-standing Prettier issue with unwanted newlines after opening braces. Requires Prettier >=2.x.
