prettier-plugin-packagejson

A Prettier plugin that automatically sorts the keys of package.json files using sort-package-json. The current stable version is 3.0.2, released March 2026. It releases frequently (multiple versions per month) and only supports Prettier v3+ (dropped v2 support in v3.0.0). Key differentiators: provides a customizable sort order via the `packageSortOrder` option, ships TypeScript type declarations, and integrates seamlessly with Prettier's plugin system.
