    Suggested: We strongly suggest you enable Strict Mode in your Next.js application to better prepare your application for the future of React.

    React's Strict Mode is a development mode only feature for highlighting potential problems in an application. It helps to identify unsafe lifecycles, legacy API usage, and a number of other features.

    The Next.js runtime is Strict Mode-compliant. To opt-in to Strict Mode, configure the following option in your next.config.js:

    module.exports = {
      reactStrictMode: true,

    If you or your team are not ready to use Strict Mode in your entire application, that's OK! You can incrementally migrate on a page-by-page basis using <React.StrictMode>.
