I just installed Next.js and created a new app. After running npm run dev, the app successfully loads the default Next.js page. However, when I make changes to page.js, the changes don’t take effect and aren’t reflected on the page.

Hi @worthy umbra. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the knowledge sources, it appears you're experiencing an issue with hot reloading in Next.js. This is a common problem that can occur for various reasons. Here are some potential solutions and things to check:

  1. Make sure you're using the latest version of Next.js. Some older versions had issues with hot reloading that have been fixed in newer releases.

  2. Check if you're using a custom server setup. According to this issue, hot reloading might not work properly with custom server configurations.

  3. Verify that you're running the development server correctly. As mentioned in the Next.js documentation, you should:

    • Run npm run dev to start the development server
    • Visit <http://localhost:3000> to view your application
    • Edit the app/page.tsx file (or pages/index.tsx if you're using the Pages Router) and save it to see the updated result in your browser

  4. If you're using the App Router, make sure your layout file is correctly set up. As suggested in this comment, wrapping the {children} in html and body tags might help:

    <html>
  <body>{children}</body>
</html>

  5. Double-check your imports and make sure there are no typos or errors in your code that might prevent hot reloading from working correctly.

  6. If you're using Docker, be aware that hot reloading might not work out of the box. This is a known issue as mentioned in this GitHub issue.

#

If none of these solutions work, you might want to try creating a new Next.js project using the latest version and see if the issue persists. If it does, consider opening an issue on the Next.js GitHub repository with detailed information about your setup and the steps to reproduce the problem.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
