Describe the bug

The base property would be changed when it got base on configResolved hook.

Reproduction

  base: 'http://localhost:8000/',
  plugins: [
    {
      name: 'test',

      configResolved(config) {
        console.log(config.base);
      },
    }
  ]
});

it prints '/' not 'http://localhost:8000/'

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn’t already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it’s a Vue SFC related bug, it should likely be reported to https://github.com/vuejs/vue-next instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.

Don’t want to increase the noise here, so I edited my previous comment.

In most cases, users that want to provide a full origin to base in development should use server.origin instead, which was added in:

We also discussed in the last meeting that this is intentional. Vite will resolve the base for it’s internal use. You can use server.origin for other cases.
