Express server help

[jwilson114]

I am trying to add next boost to my existing next app with a custom express server. From the express example I am struggling to understand how to implement the render method. I have a couple of urls that are nested categories and route to the same next.js page so I use the app.render method. How can this be done using the CachedHandler... from the example I can only see that the CachedHandler().handler is available.

await app.render(req, res, '/b', query)

The above is taken from https://nextjs.org/docs/advanced-features/custom-server

Thanks
