This updates the docs to better support Next.js v16. Update the recommended usage pattern for
nextJsApiRouter()to exportconfigas a static literal. Deprecate theconfigproperty on theApiRoutereturn type.Next.js 16 uses Turbopack as the default bundler. Turbopack reads the AST of route files at compile time to extract config values like
api.bodyParser. It only recognizes inline export declarations (export const config = ...) and does not trace references from export specifiers (export { config }) back to their declarations. See the custom config examples.The previously recommended pattern re-exported
configfrom thenextJsApiRouter()return value, which produces an AST node with no inline initializer. Turbopack treats this as a fatal error (upgraded from warning in vercel/next.js#83297).Contributes towards #1645
