Why do I have to restart the Next.js dev server to see changes?

I have a Next.js project that has been a real delight to work on until recently when changes stopped showing up in the browser. Normally the browser hot reloads, but now even hitting refresh won't show changes to the code—I have to shut down the dev server and run npm run dev again to get the changes to show up. This doesn't happen in all my Next.js projects—just one of them.

I've tried deleting the .next/ directory, but that didn't fix the problem. Any other ideas of where I could look to get this back to normal?

I experienced a similar issue, and in my case, it was due to case sensitivity.

I had renamed one of my components with only a minor change in the letter case (e.g., MyNextComponent.tsx -> MynextComponent.tsx). I updated all the import paths accordingly, but missed one small typo in one of the pages: import MyNextComponent from '@/component/MynextComponent.tsx'.

Everything seemed to work fine after restarting the server, but hot reload or even a browser refresh didn't reflect the changes, just like the original poster described. Once I fixed the typo, everything started working correctly again.

So, double-check for any case sensitivity issues or typos in your import paths. Fixing these can resolve the need to restart the server to see changes.

I have the same issue. Check Import's uppercase and lowercase of your file name to resolve it import ConfirmApplications from "@/components/dos/candidate/confirmApplication";

to

import ConfirmApplications from "@/components/dos/candidate/ConfirmApplication";

If you are using next.js. Simply use

npm run dev

and make sure you have "scripts":{"dev": "next dev"} line added to your package.json.

Hope it helps

I had the same issue. In my case it was case sensitivity.

It turned out I renamed one of my components where the new name only had a letter changed from uppercase to lowercase (e.g. MyCOmponent.tsx -> MyComponent.tsx).

I made all the changes everywhere but missed one, the import path of the component in one of the pages. I had: import MyComponet from '../../MyCOmponent.tsx'

Everything still worked when restarting the server, but hot reload or even browser refresh wouldn't, same as OP. Fixing the typo fixed everything.

I faced the same issue. I created a new file with a different name and copied all the content which was inside the file that did not show the changes. Then it started showing the changes in the browser.
