Overview

Root npm package manifest that defines the promptfoo package metadata, build scripts, dependencies, entry points, and workspace configuration.

Description

The Package_Manifest (package.json) is the root npm configuration for the promptfoo package. It defines the package as an ESM module (type: module), specifies dual entry points (ESM index.js and CJS index.cjs), configures binary commands (promptfoo and pf), lists 100+ dependencies, defines 30+ npm scripts for building, testing, linting, and development, and sets up workspaces for src/app (web UI) and site (docs). The engines field constrains Node.js to ^20.20.0 || >=22.22.0.

Usage

This file is consumed by npm/pnpm/yarn for dependency installation, script execution, and package publishing.
