prettier-plugin-sort-package-json

Prettier plugin that automatically sorts the keys in package.json files. Current stable version is 1.1.0, released in April 2025. This plugin is a zero-dependency, opinionated tool that works out of the box with no configuration. It supports all keys defined in the npm v11 package.json documentation and also provides a custom parser for sorting package.json-like files. Unlike alternatives (e.g., sort-package-json standalone CLI), it integrates directly into Prettier's workflow, enabling auto-formatting on save and consistent sorting across teams without extra scripts.
