3. If we don’t possess a cache entry for this request, we continue with normal Universal SSR and we save the effect HTML in the cache before we return it as the response. Be careful using what you cache! You should only cache the webpages that truly exist on the application or website, or make sense to cache. So stay away from the caching of non-existing webpages.

This could potentially lead to a memory-issue on your server.404 not found web pages. Consequently, your server will become very slow and might eventually even crash. A straightforward way to mitigate this risk is by using (a variant of) your sitemap.xml to whitelist the allowed pages. This is implemented on lines 11-13 of the code shown above. In this case we are just allowing the /, and /contact pages to be cached /about.

The concepts described above only touch the fundamentals of implementing a caching strategy and infrastructure. There are several improvements possible that I will explain briefly. Rather than letting the first visitor of your website is responsible for generating the first cached version of specific pages, we can generate the static versions of all the pages of our application at build time. We can do that for example after producing our sitemap.xml.

At that point we realize all the available urls of our program/website and we can generate the static variations of those webpages and put them in the cache. Maintaining the cache of a small website such as this one is easy. Everytime a new version is available, I clear the cache completely. The first visitor of a specific page is responsible for creating the cached version now.

In bigger applications a user interface to dynamically update and clean the cache is required. For instance, when using a CMS to include a full page or blog post you can result in a cache-request immediately after saving this content. In the event that you delete a page, you can wipe out the cache, to make sure your visitors are not seeing a page that has already been deleted. Make sure to apply some security on this interface.

You don’t want someone destructive messing with your cache. On this example we have applied caching at the amount of the offering software. This lovers our server software to the caching infrastructure straight. A far more advanced approach would be to install a caching layer right before the application form server. This may either be a very different (virtual) machine or run as a supplementary service on the same machine as the one operating our Node.js Express server.

This way we can decouple our caching infrastructure completely from our offering application. In some instances it could not be asked to SSR and cache all web pages of the application. You might have a public facing part of the application and a private part that will require a login. This content of the private part could be very volatile, so caching is not your best option there perhaps.
