| description: Configuration options for the on-screen indicator that gives context about the current route you're viewing during development. | |
| --- | |
| `devIndicators` allows you to configure the on-screen indicator that gives context about the current route you're viewing during development. | |
| ```ts filename="Types" | |
| devIndicators: false | { | |
| position?: 'bottom-right' | |
| | 'bottom-left' | |
| | 'top-right' | |
| | 'top-left', // defaults to 'bottom-left', | |
| }, | |
| ``` | |
| Setting `devIndicators` to `false` will hide the indicator, however Next.js will continue to surface any build or runtime errors that were encountered. | |
| ## Troubleshooting | |
| ### Indicator not marking a route as static | |
| If you expect a route to be static and the indicator has marked it as dynamic, it's likely the route has opted out of static rendering. | |
| You can confirm if a route is [static](/docs/app/getting-started/partial-prerendering#static-rendering) or [dynamic](/docs/app/getting-started/partial-prerendering#dynamic-rendering) by building your application using `next build --debug`, and checking the output in your terminal. Static (or prerendered) routes will display a `β` symbol, whereas dynamic routes will display a `Ζ` symbol. For example: | |
| ```bash filename="Build Output" | |
| Route (app) Size First Load JS | |
| β β /_not-found 0 B 0 kB | |
| β Ζ /products/[id] 0 B 0 kB | |
| β (Static) prerendered as static content | |
| Ζ (Dynamic) server-rendered on demand | |
| ``` | |
| <AppOnly> | |
| There are two reasons a route might opt out of static rendering: | |
| - The presence of [Dynamic APIs](/docs/app/getting-started/partial-prerendering#dynamic-rendering) which rely on runtime information. | |
| - An [uncached data request](/docs/app/getting-started/fetching-data), like a call to an ORM or database driver. | |
| Check your route for any of these conditions, and if you are not able to statically render the route, then consider using [`loading.js`](/docs/app/api-reference/file-conventions/loading) or [`<Suspense />`](https://react.dev/reference/react/Suspense) to leverage [streaming](/docs/app/getting-started/linking-and-navigating#streaming). | |

| When exporting [`getServerSideProps`](/docs/pages/building-your-application/data-fetching/get-server-side-props) or [`getInitialProps`](/docs/pages/api-reference/functions/get-initial-props) from a page, it will be marked as dynamic. | |
