devIndicators

devIndicators allows you to configure the on-screen indicator that gives context about the current route you're viewing during development.

  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 or dynamic by building your application using next build --debug, and checking the output in your terminal. Static (or prerendered) routes will display a ○ symbol, whereas dynamic routes will display a ƒ symbol. For example:

Route (app)                              Size     First Load JS
┌ ○ /_not-found                          0 B               0 kB
└ ƒ /products/[id]                       0 B               0 kB
 
○  (Static)   prerendered as static content
ƒ  (Dynamic)  server-rendered on demand

When exporting getServerSideProps or getInitialProps from a page, it will be marked as dynamic.
