## Caveats

- With `next export`, we build an HTML version of your app. At export time, we call [`getStaticProps`](/docs/basic-features/data-fetching.md#getstaticprops-static-generation) for each page that exports it, and pass the result to the page's component. It's also possible to use the older [`getInitialProps`](/docs/api-reference/data-fetching/getInitialProps.md) API instead of `getStaticProps`, but it comes with a few caveats:

- It's also possible to use the older [`getInitialProps`](/docs/api-reference/data-fetching/getInitialProps.md) API instead of `getStaticProps`, but it comes with a few caveats:

- `getInitialProps` cannot be used alongside `getStaticProps` or `getStaticPaths` on any given page. If you have dynamic routes, instead of using `getStaticPaths` you'll need to configure the [`exportPathMap`](/docs/api-reference/next.config.js/exportPathMap.md) parameter in your [`next.config.js`](/docs/api-reference/next.config.js/introduction.md) file to let the exporter know which HTML files it should output.
- When `getInitialProps` is called during export, the `req` and `res` fields of its [`context`](/docs/api-reference/data-fetching/getInitialProps.md#context-object) parameter will be empty objects, since during export there is no server running.
