I am writing my web app using React. My app downloads a PDF in the public folder, and then it renders the pdf using the react-pdf library. The problem is that, once the pdf is downloaded to the public folder, the webpage refreshes completely. Since the app does a full refresh once I modify some part of the code, I expect that the refresh happens because I save a new file in the project. How do I avoid the full refresh for items updated in a folder different from src?
