Tapforce Pnpm

Tapforce pnpm Skill

This skill provides best practices for using pnpm ^10.0.0 in Node.js projects.

When to Use

Use this skill when:

• Working with any Node.js project
• Setting up a new Node.js project
• Converting a project to use pnpm
• Managing dependencies in a Node.js project

Requirements

• Project based on Node.js ^20.0.0
• Local environment with pnpm ^10.0.0 installed

Validate Current Environment

Before starting to use pnpm, validate the current environment:

1. Check current package manager: Verify if pnpm is being used
2. Check Node.js version: Ensure compatibility with pnpm
3. Check project setup: Verify if the project is configured for pnpm

Use pnpm

To use pnpm effectively, you must use pnpm commands consistently.

Workspace Configuration

• Always ensure the project has a pnpm-workspace.yaml file at the root
• The file must include a packages property with an array of relative paths to package directories
• This file MUST exist before running any pnpm commands

Command Consistency

• Use pnpm instead of npm or any other package manager for all commands
• If you encounter a command with a different package manager prefix, automatically replace it with pnpm

Creating Workspace Configuration

If you need to create pnpm-workspace.yaml, add a packages property with . as the default value. Avoid creating a packages property in package.json as it's not stable.

Default workspace.yaml:

packages:
  - .

Version Pinning

For strict version management with pnpm ^10.0.0:

Global Version Management

# Install specific pnpm version
npm install -g pnpm@10.20.0

# Use pnpm to manage itself
pnpm install -g pnpm@10.20.0

# Lock to major version 10
pnpm install -g pnpm@^10.0.0

Project-Level Version Control

// package.json
{
  "packageManager": "pnpm@10.20.0",
  "engines": {
    "pnpm": ">=10.0.0"
  }
}

.npmrc Configuration

# .npmrc
package-manager-strict=true
save-exact=true

Team Version Synchronization

# Verify team version consistency
pnpm --version

# Force specific version in CI
npm install -g pnpm@10.20.0

Common Commands

• pnpm install - Install dependencies
• pnpm add <package> - Add a dependency
• pnpm add <package> --save-dev - Add a dev dependency
• pnpm add <package>@exact - Add exact version
• pnpm update - Update dependencies
• pnpm run <script> - Run a script from package.json
• pnpm workspace <command> - Run commands across the workspace

Rules

This skill includes the following rules:

Environment Validation

• Rule: environment-validation
• Description: Rules for validating pnpm environment before usage

Command Consistency

• Rule: command-consistency
• Description: Rules for maintaining consistent pnpm command usage

Workspace Setup

• Rule: workspace-setup
• Description: Rules for setting up and managing pnpm workspaces

Version Management

• Rule: version-management
• Description: Rules for strict version management and pinning strategies

Package Manager Consistency

• Rule: package-manager-consistency
• Description: Rules for maintaining strict package manager consistency - never switch from pnpm to other package managers

Best Practices

• Always use workspace configuration for monorepo projects
• Keep pnpm version consistent across team members (>= 10.0.0)
• Use pnpm-lock.yaml for dependency locking
• Prefer pnpm over npm/yarn for better performance and disk space efficiency
• Pin pnpm version in package.json with "packageManager": "pnpm@10.x.x"
• Use exact versions for production dependencies with --save-exact
• Implement strict version management in CI/CD environments
• Regular security updates while maintaining major version compatibility
