Uninstalling npm packages removes unused dependencies from your Node.js project, keeping your codebase clean and reducing bundle size. As the creator of CoreUI, a widely used open-source UI library, I’ve managed countless package installations and removals across different project configurations. From my expertise, the npm uninstall command properly removes packages from both your node_modules folder and package.json dependencies. This approach ensures clean dependency management and prevents unused packages from bloating your project.
