⚖️ @elilands/npm-weight

The elite CLI to calculate the real cost, weight, and health of your npm dependencies.

Ever wondered how much bloat you are actually shipping to your users? Not all dependencies are created equal. Some are lightweight and actively maintained, while others are massive, outdated, and silently killing your app's performance.

npm-weight scans your local package.json, bridges directly with the NPM Registry and Bundlephobia, and generates a visual dashboard of your project's health. It separates your client-side payload from your dev-tools, grades them with a strict Health Score, and even auto-updates outdated packages for you.

✨ Features

• 🧠 Contextual Health Scores: Automatically grades your packages (A, B, C, F) based on their GZIP size and age. It smartly forgives devDependencies for being heavy, but strictly audits your dependencies.
• 🌐 Network Orchestration: Fetches real-time data from NPM and Bundlephobia concurrently to give you the exact physical weight of your code.
• 🔧 Interactive Auto-Fix: Detects outdated packages and interactively asks if you want to auto-update them to their latest versions using your native package manager.
• 🤖 CI/CD & GitHub PR Ready: Export pure JSON for your pipelines or raw Markdown tables to paste directly into your Pull Request comments.
• ⚡ Zero Bloat: Built with modern TypeScript and ESM. Fast, reliable, and strictly typed.
