Identify unused npm packages in your project
If you’re working on a large codebase, chances are you might have installed a lot of npm packages in your project. And you might have used some of them just for the sake of trying them out. But, you might have forgotten to remove them from your package.json file.
These unused packages can unnecessarily increase the bundle size of your project. So, it’s better to remove them from your project.
Here’s how you can identify the unused npm packages in your project.
