[gatsby-plugin-remark] Get the whole content without HTML and Markdown

[Destroy666x]

Summary

As the title says, I see no way to get Markdown content without HTML or Markdown (including frontmatter), I didn't find a custom plugin for that either. I guess you could use excerpt with an enormous value, but that's counterintuitive.

Basic example

internal {
  content
}

returns the whole Markdown structure including frontmatter.

html on the other hand returns HTML version of it without frontmatter.

Motivation

It supports cases such as getting content ready for e.g. indexing for search or RSS in a understandable (not "Why are you getting an excerpt with 999999 size there?") way without the need of postprocessing with JS.

Where do you want this data? In you gatsby-node.js? This seems a bit niche maybe to directly support in the schema — you can just use gray-matter (which is what gatsby-transformer-remark users) to extract the body out from the frontmatter.

But I suppose we could add a field like rawMarkdownBody or something which would do the transformation for you.

This seems a bit niche maybe

Well yeah, there aren't too many use cases, but IMO more than for e.g. timeToRead. And e.g. the RSS use case could appear more times in the future here since the plugin is maintained in the core.

This will be available via rawMarkdownBody thanks to #5557
