Additional context

My project was running on dev server. I closed the server to install axios, which happend with no issues. I runned the npm run dev command and the server never rendered, it is frozen on the "ready" message. I created a new folder, installed Next again, with the npx create-next-app command and copied all my project files into that folder and it was running with no issues, even with axios installed. I took another pause and when I went back to the project, the same issue happend: the project is not rendering and is stuck on the "ready" message, as the image below shows:

extent analysis

TL;DR

  • Try reinstalling dependencies or checking for file system issues to resolve the "ready" message freeze in the Next.js dev server.

Guidance

  • Verify that the issue persists after running npm install to ensure all dependencies are properly installed and up-to-date.
  • Check the file system for any potential issues, such as file corruption or permissions problems, that could be causing the dev server to freeze.
  • Attempt to run the dev server with the --verbose flag to gather more detailed output and potentially identify the source of the issue.
  • Consider trying a different version of Node.js, as the issue may be related to the current version (22.14.0) being used.

Example

No specific code snippet is applicable in this case, as the issue appears to be related to the development environment and file system rather than a specific code problem.

Notes

  • The issue seems to be intermittent and may be related to the specific environment or file system being used.
  • The fact that creating a new project and copying files into it resolves the issue suggests that the problem may be related to the project's configuration or file system state.

Recommendation

  • Apply workaround: Try reinstalling dependencies or checking for file system issues, as this may resolve the "ready" message freeze without requiring a version upgrade.
