This example demonstrates how to use next-pwa to implement fallback routes for page, image or font when fetch error. Fetch error usually happens when offline. (Note fetch is successful even when server returns error codes 404, 400, 500, ...)

Simply add a /_offline page such as pages/_offline.js or pages/_offline.jsx or pages/_offline.tsx. Then you are all set! No configuration needed for this.

You can configure fallback routes for other type of resources

pwa: {
  // ...
  fallbacks: {
    image: '/static/images/fallback.png',
    // document: '/other-offline',  // if you want to fallback to a custom    page other than /_offline
    // font: '/static/font/fallback.woff2',
    // audio: ...,
    // video: ...,
  },
  // ...
}
