gatsby-plugin-mdx doesn’t hot reload frontmatter

[leafac]

Description

Hot reloading doesn’t work when I change the frontmatter in an .mdx file. I have to rerun gatsby develop to observe the changes.

Steps to reproduce

Here’s a project that exemplifies the issue:

gatsby-mdx-frontmatter-hot-reload.zip

Run:

$ npm install
$ npx gatsby develop

Visit http://localhost:8000. Change the title in the frontmatter in src/pages/index.mdx. Observe how the contents in the browser don’t change, not even if you refresh the page. You have to restart Gatsby.

Expected result

The frontmatter should hot reload, just like the contents of the page do.

Actual result

The frontmatter doesn’t reload.

Hey @leafac

So sorry it's been 19 days with no response. I'm going to try and look into this soon. Our team is running in a limited capacity due to Covid-19 which is a bit to explain why it took so long. But I just wanted to drop a comment to let you know I'll be looking into this (ideally) this week.

Don’t worry about it. We all have bigger fish to fry.

A quick workaround for me is to rename the mdx file to page.mdx_, then back to page.mdx and save the content again - at least its better than restarting the whole building process.
