Going back to this topic. Is there a way to store .md on my gateway and only refer to that using a link?
The goal for me would be to share a set of documents between different gateways and get all files updated at once if needed.
As well, I find it more comfortable to edit my markdown files in VS, then would just drag all updated files in my gateway.
I split this into a new topic since the original OP's question was different.
That said - generally no, at this point in time there's no way to store arbitrary files (in a referenceable way) into Ignition in a way that works very well.
You can mount arbitrary files and folders to expose them over HTTP via the WebDev module (or database records via Phil's free 'Blob Server' module) - but consuming them as HTTP in Perspective would be a manual process involving HTTP bindings.
In some future version of Ignition we're hoping to add a 'platform' level "arbitrary file" resource that would work basically the same as Webdev's current file hook but not require an external module.
