Access urlParams

[dipterix]

Is it possible to save the urlParams into the WASM apps so the application can tweak its behaviors according to the URL params? Happy to propose a PR

I was able to hack the shinylive source code to achieve this: https://github.com/rave-ieeg/rave-wasm/blob/a4d4b20a632d202242138cf459f287aff7256b44/compile.r#L466-L477

Here is an Example: the same app has different initializations according to the URL params

Original app: https://rave.wiki/rave-wasm/nsd-ieeg-viewer/index.html

App with urlParams:

This effectively a duplicate of #28; if you follow the threads there you might find some helpful advice.

Thank you. Glad that someone has already posted questions. However, it seems the url params are not set into the inner apps. I tried both

options(passUrlParams = TRUE)
shiny::shinyApp(ui = ui, server = server, options = list(passUrlParams = TRUE))

I wonder if it's possible that I missed anything? Would you mind helping me? Thanks : D

You're not missing anything; that's exactly the way in which your issue overlaps with the issue I linked. We don't currently have a great solution, although there might be some useful details and conversations that link back to the issue I mentioned.

Ah I see... So right now there is no way to pass the urlParams to the wasm apps...

I proposed a PR just to save the params dynamically into the app directory as .urlParams file. The app can optionally use this file. It might be a safe start? As existing apps won't be affected at all.

Thanks for the PR but our overall goal would be to natively support the url* properties in session$clientData as mentioned in your screenshot.

If you own the containing page where the shinylive app is being run, you can use the trick in this comment: rstudio/shiny#4153 (comment)
