No documention on using files cached by createRemoteFileNode

[ajayns]

While working with remote files, the current documentation that we wrote is pretty clear on how to use the function, but I feel we need to add an example of how to use such files in a Gatsby project.

Makes sense! Would love a quick example added of how you can then query the local file.

Is there any existing use case that you can point me to, so that I can work on a PR? @KyleAMathews

Isn't that specifically for images? Wouldn't it be better to add an example for general files so that they include linking documents, videos and everything else as well. @KyleAMathews

[KyleAMathews]

Your hypothetical example can be about whatever you'd like it to be :-)

So in cases of files, I was thinking the data URL can be queried by relativePath in Gatsby, and then used in the project as <a href="path-here">File</a>.
Is this approach advisable?

[KyleAMathews]

No — createRemoteFileNode is only for use by source/transformer plugins that know about a remote file and want to pull it locally. The downloaded files aren't findable via directly searching. That's why the examples on source-filesystem and source-wordpress have you querying the file through other data.

Oh I wasn't aware of that. So in the case of remote files, say a PDF and maybe even a mp4 video that's stored in the CMS, what's the best approach to sourcing these files in a plugin? @KyleAMathews

Also, I'll try to add an example usage to the wordpress handling images only then.

Before I close this issue, I'd really appreciate a bit of help from the community on how to handle remote files as mentioned above! Any suggestions on best approach are appreciated!
