• Type: string | string[]
  • Default: undefined

Uniformly set the prefix of server-side routes (commonly used in situations where multiple applications share the same domain name to distinguish traffic).

export default defineConfig({
  server: {
    // All generated routes will automatically have the prefix `/base`
    // Generated server-side route file path: dist/route.json
    baseUrl: '/base'

    // Multiple baseUrl
    baseUrl: ['/base-new', '/base-old']

After running dev, you will see that the route access will have the corresponding prefix added:

> Local:    http://localhost:8080/base/
  > Network:
