# server.ssrByEntries

- **Type:** `Object`
- **Default:** `undefined`

Set SSR options by entry, and the properties inside the option are the same as [ssr](/configure/app/server/ssr.md). The specified value will be replaced and merged with the content of the SSR attribute, for example:

:::info
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.

:::

```ts title="modern.config.ts"
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.
