Microsoft introduces the JavaScript/TypeScript Modernizer, an AI-powered VS Code extension that automates upgrading npm packages and fixing breaking changes in JS/TS projects. Available in VS Code Insiders as part of the GitHub Copilot App Modernization extension, it analyzes package.json files, proposes upgrade plans, updates dependencies to latest versions, and suggests necessary code changes through an interactive Copilot Chat experience. The tool requires VS Code Insiders, Node.js/npm, GitHub Copilot access, and enabling an experimental feature flag. Currently in preview with limitations including single-project support and potential rough edges.
