This does not seem to be a bug of Vue, as the rerender and reload functions of HMR are not executed after changing the file.

Could you open an issue in Vite and preferably provide a minimal reproduction without other third-party dependencies?

I'll close this for now. If you have any new problems on vue, please reopen this issue. Thanks!

@zhangzhonghe hello, the reproduction has some problem. I updated it. Removed almost all dependences. Now the bug can be exactly trigged. You can simply disable/enable this bug by comment/uncomment the line 17 of /src/pages/login/modules/requests. Can you check again about it?

You should not import the main.ts file directly here. It causes the app.mount('#app'); runs multiple during HMR.

The console has a warning when triggering HMR:

Ohhh, thank you for the checking of it. I will rearrange my codes like this case in the project.
