I use createPages and I get hot reloading when running gatsby develop.

I also just figured out how to trigger hot reloading for sources that normally don’t trigger it (markdown files which I was manually processing).

Basically, I discovered that gatsby will hot-reload when it sees a change in code files (.tsx). So I created an essentially empty _rebuild-trigger.tsx file and imported that in my main page template.

Now, to change the page content and trigger a hot-reload:

- I have an observable subscribed in createPagesStateful that calls deletePage and createPage - Then write to the file _rebuild-trigger.tsx file

I need to make a blog post because it works great (and I could tie it to any change source - like file system watcher - during development).
