Dependency Management Guide

This document outlines the process for updating NPM dependencies in the LiveStore project. We use pnpm update as our primary tool with syncpack for validation. Update all dependencies across the entire monorepo.

Quick Start

# 0. Update PNPM itself first
pnpm --version  # Check current version
pnpm view pnpm version  # Check latest version

Enforce Explicit Value Comparisons

Detects shorthand value usage patterns (implicit truthiness/falsiness checking) in JavaScript/TypeScript code. This rule helps identify places where explicit comparisons might be preferred for clarity and type safety. Common cases include checking for undefined/null, empty strings, zero values, and boolean states.
