Fix Peer Dependencies

A Node.js script to automatically check and add missing peer dependencies for your project. This script works for both single-package projects and monorepo workspaces.

Features

• Automatically checks for missing peer dependencies after adding a new library.
• Can be run manually via a custom command to check all dependencies.
• Supports workspace mode (monorepos) using -ws flag.
• Zero external dependencies.

Installation

Install the package globally to use the fix-peerds command:

npm install -g fix-peerds

Usage

Automatically check after adding a new library

After adding a new library with pnpm add <library>, the script will automatically verify if the new library has peer dependencies, and if any are missing from your package.json, they will be added.

{
  "scripts": {
    "postinstall": "fix-peerds"
  }
}

Manually check peer dependencies

You can manually run the peer dependency check with:

fix-peerds

The script will analyze the installed libraries and check if the peerDependencies of each one are listed in your project's package.json. If any are missing, it will automatically add them.

Workspace mode (Monorepos)

If you are working in a monorepo (multi-package workspace), you can check peer dependencies across all sub-packages:

fix-peerds -ws

This will scan the workspace configuration (such as pnpm-workspace.yaml or package.json with workspaces defined) and run the peer dependency check in each sub-package.

Example

pnpm add some-library
# Automatically checks for peer dependencies

fix-peerds
# Manually checks for peer dependencies

fix-peerds -ws
# Checks peer dependencies across workspace projects
