{/* The content of this doc is shared between the app and pages router. You can use the `<PagesOnly>Content</PagesOnly>` component to add content that is specific to the Pages Router. Any shared content should not be wrapped in a component. */}

Next.js 提供了一些选项，让你可以控制服务器在开发环境中如何处理或保留已构建的页面。

要更改默认设置，请打开 `next.config.js` 并添加 `onDemandEntries` 配置：

```js filename="next.config.js"
module.exports = {
  onDemandEntries: {
    // period (in ms) where the server will keep pages in the buffer
    maxInactiveAge: 25 * 1000,
    // number of pages that should be kept simultaneously without being disposed
    pagesBufferLength: 2,
  },
}
