You can go one of two routes (get it? routes?):
Although there are plenty of alternatives at this point, you’re probably using Webpack. Your best option, in this case, is probably prerender-loader, a Webpack plugin. It relatively painless to set up, but you might have a hard time setting it up for multiple routes.
If you’re using Parcel, you’re in luck. This guide can walk you through how to set up SSR. Yes, you will have to go through some boilerplate (which is ironically, exactly what Parcel is supposed to help you avoid), but your existing code shouldn’t see many changes. However, you can still use React Router, along with routing animations, styled-components, etc.
I personally don’t like either of these approaches, partly because of the boilerplate, but mostly because there is a better option - prerendering.
Uses Headless Chrome to crawl all the routes of your app and generates static HTML for each of them. It works with create-react-app, Preact and Vue. There’s close to no configuration and the authors have even provided a chart comparing it to similar solutions. Apart from the caveats mentioned in the Readme you should be aware that if you’re using some type of CI or Docker you’ll likely have to set up Pupeteer so the postbuild script that executed during deployment will be successful.
This service is paid for apps with more than 25 pages. The set-up consist of installing a package and adding a line of code to your server (there’s support for all the popular backend frameworks). It’s open-source and recommended by Google. Note that the middleware is only used when a web crawler is visiting your app. Users won’t see a benefit from this (apart from finding your app more easily due to the improved SEO). Which is why i recommend react-snap, because of the added performance boost. If you want to use prerender.io, but want to avoid the monthly fees you can run it in your own server. Here’s a docker image to get you started.
Whichever method you chose, you’ll benefit from better SEO of your app and your users will experience faster loading speeds. So if you haven’t already, consider investing some time to make your app isomorphic.
