How to check if a link exists?

[awlobo]

Hi! I am using dataviewjs and I was wondering if it is possible to check if a link goes somewhere or not.
I'm using var link = dv.func.link("random name")and basically, I want to display the link to the file if it exists or display just the name if there is no file to go to.

What I want to avoid is to have this dead links:

Thnaks!

Ideally, I'd like an enhancement to the link object to account for this but meanwhile, you could probably use the Obsidian API to find link destinations.

Is the Obsidian API well documented? Last time I checked it was basically a big ts file with the different classes and functions and so on

Haha sadly that's where we're at.

that will do I guess 😆 thanks!

You can just try looking up the page:

var link = dv.func.link("random name")
if (dv.page(link) == null) {
  // doesn't exist
}

Genius! Works like a charm! Thanks!
