DataviewJS - How can I get file URL? ( obsidian://open?vault= ...)

[Another5405]

I was making a text generate function for dv.paragraph( "mermaid text" )
I want to use URL not internal-link because mermaid will render fail with syntax like : "<< Task"
if you need to replace syntax,internal-link will not working.

I did try
let link = this.app.vault.getResourcePath(file.path)

but preview mode return
Evaluation Error: TypeError: Cannot read properties of undefined (reading 'app')

Thanks for help!

I think you should be able to just use app and not this.app, since app is a global variable in Obsidian.

I tried:

let file = app.workspace.getActiveFile();
let link = app.vault.getResourcePath(file.path)

return:
Evaluation Error: TypeError: The "path" argument must be of type string. Received undefined

I don't know what Error mean,sorry
file.path will be a type of string but not working?

Try logging file to console. In fact, execute these commands in console and inspect the output. It's likely that getActiveFile() isn't returning what you expect.

I tried getResourcePath

it return:
app://local/Users/user/....

but I want:
obsidian://open?vault=...

I don't know which code return URL format,
How can I get the file URL?

There is an undocumented API that is prone to change down the road that does this: app.getObsidianUrl(file: TFile)
