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. ## Full article daily.dev links to this article rather than hosting it.
