Due to the recent changes in plugin loading, Gatsby will no longer run a
gatsby-browser.js
file that doesn't export any Gatsby APIs.This was affecting a couple of plugins which I've fixed up in this PR, along with some tweaks to the Using Remark example site.
There's room for further improvement here, as silently ignoring a plugin file is not very helpful. My suggestion is that when loading a plugin, Gatsby should show a warning for any
gatsby-browser.js
,gatsby-node.js
orgatsby-ssr.js
files that exist, but don't export any valid APIs. Does that sound sensible? Is there a better approach?Closes #4318
