-Any route that starts with a prefix listed in `ignore` will be ignored.

+Any route specified in `routes` will be fetched during the build and copied to the `.output/public` directory as a static asset.

+If `crawlLinks` option is set to `true`, nitro starts crawling `/` by default (or all routes in `routes` array) and for HTML pages extracts `<a href="">` tags and prerender them as well. Nitro also reads from the `x-nitro-prerender` header send back to crawl extra routes.
 
-If `crawlLinks` option is set to `true`, nitro starts with `/` by default (or all routes in `routes` array) and for HTML pages extracts `<a href="">` tags and prerender them as well.
+The `ignore` option accepts an array of string or regex to specify the routes to ignore. Routes that starts with the string or matches the regex will be ignored.
