Statically rendered user pages + concept pages

[rohitpaulk]

We've been pre-rendering track pages and challenge pages by enumerating over all available tracks and challenges. We now need to find a way to statically generate user pages (there are 1000s of these), and concept pages (we'll have 100s of these in the near future).

Vercel's Prerender functions API is supposed to allow for generating these on demand and caching. Let's implement this and also see if we can expose this as a generic ember plugin that others can use.

@VasylMarchuk can you look into this please?

@VasylMarchuk this is a bit time-sensitive, let's try to have it out by Feb 10

For additional context - the reason we can't use the existing pre-rendering setup for these is that there are 1000s of these pages, and our deploys would take hours if we were to pre-render all of these pages.

Looking into this. Also, is my suspicion correct that since we're now going to render user-generated content (their user pages), we need to fix the DOMPurify sanitize issue? @rohitpaulk

Or would this not be really related? I'm currently still reading all the docs about prerender and serverless functions to understand how they work and trying to revive all my vercel knowledge.

@VasylMarchuk yeah, we'll need to do something about that since user pages can contain UGC. It's okay if we do this in a hacky manner for now though - for example, if we just HTML-escaped all content when in fastboot mode (so it doesn't insert things like <script> tags), that might work. We can then re-visit getting DOMPurify to work properly in a different issue.
