• Type: Object
  • Default: undefined

Set SSR options by entry, and the properties inside the option are the same as ssr. The specified value will be replaced and merged with the content of the SSR attribute, for example:


The "entry name" defaults to the directory name. In a few cases, when defining an entry through source.entries, the entry name is the key of the source.entries object.

export default defineConfig({
  server: {
    ssr: true,
    ssrByEntries: {
      // page-a does not enable SSR
      'page-a': false,

In the above configuration, the project enables SSR as a whole, but the SSR rendering ability is disabled for the page-a entry.
