Dependency Diagnostics

Dependency Diagnostics is a Visual Studio Code extension that automatically checks whether the dependencies declared in all package.json files in your workspace are installed and match the expected versions, making it suitable for monorepos and multi-package repositories.

If a dependency is missing or out of sync, Dependency Diagnostics highlights it and lets you fix the issue quickly.
