pwix:seo-prerender

What is it ?

A Meteor server-only package which adds to your application a prerendering feature, suitable for SEO purposes.

Its good behavior relies on the availability somewhere of an external prerendering service, which can be either prerender.io, prerender.com, or your own local prerender service. The prerender service must be addressed by the PRERENDER_SERVICE_URL (server-side) environment variable, and must be able to address your site (be cautious when testing from a local application being developed).

It is based on prerender-node package.

On server-side, prerender-node acts as a man-in-the-middle and redirects all requests from an identified bot to the prerendering service.

What isn't ?

This is NOT a server-side rendering in the same sense that for example when using ReactJS Server Components. Here we are just caching rendered pages in order to be able to serve the for SEO usage. In particular, there is no user data provided, nor any sort of javascript hydration.

This is not either something like Meteor server-render package. This later implements some generic support for "server-side rendering in Meteor applications, by providing a mechanism for injecting fragments of HTML into the and/or of the application’s initial HTML response."

Though documentation examples are rather React-oriented, it appears clear to me that the developer has to implement in the application the code needed to render the pages. Even if the templating system (React, Blaze or any one) provides some APIs, there is still a rather amount of work to do to actually render the whole things.
