Roest 📦

A lightweight CLI tool to analyze package freshness in your Node.js or Web projects. Roest - meaning "Rust" in Dutch - helps you identify outdated packages by checking when they were last updated, making it easier to keep your dependencies current and secure.

Usage

Basic Usage

Navigate to your project directory and run:

npx roest check

This will analyze your package-lock.json file and display package update information.

Analyze GitHub Repository

You can also analyze any GitHub repository directly. In order to do this, you need to make sure you have the GITHUB_TOKEN environment variable set. You can create a new GitHub token here.

Once you have your token, run the following command:

npx roest repo owner/repository

This will find and analyze all lock files in the specified GitHub repository.

Generate HTML Report

After running an analysis, you can generate a visual HTML report:

npx roest show

This will read the output.json file and generate a report.html file with a visual representation of your package freshness data.

You can also specify custom input and output paths:

npx roest show ./custom-output.json -o ./custom-report.html
