@CHOYSEN did you test what happens when you have two dev servers running (port 3000 and 3001) and change the port?

[CHOYSEN]

It works as expect, i try to change the first dev server from 3000 to 3001. @patak-dev

test@C02FV5VTMD6M vite-config-issue 2 % pnpm dev

> vite-config-issue@0.0.0 dev /Users/test/Desktop/vite-config-issue 2
> vite


  vite v2.7.1 dev server running at:

  > Local: http://localhost:3000/
  > Network: use `--host` to expose

  ready in 403ms.

下午5:03:26 [vite] vite.config.ts changed, restarting server...
Port 3001 is in use, trying another one...
下午5:03:26 [vite] server restarted.


  > Local: http://localhost:3002/
  > Network: use `--host` to expose

For strictPort, we print the error and waiting for user to change the port again.

import { defineConfig } from "vite";

export default defineConfig({
  server: {
    port: 3000,
    strictPort: true
  }
});

Change to port 3001:

test@C02FV5VTMD6M vite-config-issue 2 % yarn dev
yarn run v1.22.10
warning package.json: No license field
$ vite

  vite v2.7.1 dev server running at:

  > Local: http://localhost:3000/
  > Network: use `--host` to expose

  ready in 380ms.

上午11:30:31 [vite] vite.config.ts changed, restarting server...
Error: Port 3001 is already in use

Change to port 3002:

上午11:31:07 [vite] vite.config.ts changed, restarting server...
上午11:31:07 [vite] server restarted.

It would be nice to handle host as well so we can close #5996.

Not sure what's up with CI, but this looks good to me.

I re-run the jobs, CI is a bit moody lately. We need to move away from Jest, we are working on it 😉
