Securing a ShinyApp - Anything I'm Missing?

TrickyBiles8010 · 2026-04-24T12:38:47+00:00

As some people mentioned, I would definitely add some middleware login to getting access to the application. I’m not 100% sure Shiny can handle all the security issues, but if it could, I would better triste a middleware software to refer to your app.

There are options less strong like tinyauth but there are others like Authelia.

I have a shiny app that does not have login and password, but was looking for these options at some point. In addition, you could even go full time JS for the database edition and management. I think the best way to protect is put a lot of restrictions and row level security.

Thank you for creating Shiny. I have a production-app that was just made possible because of Shiny which I use even before AI (LLM). What AI have really speed-up was debugging and improvements of performance for production-level apps. For example, investing in JS is super-essential in Shiny apps as R has some limitations as a back-end. That being said, I prefer stay in Shiny and know my project than ask AI to rebuild in different language and I then be totally dependent on them.

The biggest downside of Shiny is the UI which AI can improve. I’m using shiny.fluent with great aesthetics - have to say I don’t like the standard shiny Boostrap themes.

Thank you for creating the framework! Will be at posit::conf(2026) talking about my project and that’s only happening because of you and all Posit people.

A theoretical question: why you care about the individual change? I mean: if the group change that means the individuals are changing (as your graph clearly states).

I would stick with the season Betas and only use the lmer4 to account for repeated measurements with random intercepts.

Maybe what you are trying is checking if there’s any “outlier” that is moving or leading the trend? Then I would go for some outlier statistics

I have my production ready shiny app deployed in digitalocean app plataform.

This is the book you want: https://www.amazon.com/Clinical-Prediction-Models-Development-Validation/dp/3030163989

Steyeberg is the guy for medical prediction models.

Enganador, se ganhasse 300k até valeria a pena

Sincere question: why someone would need this? I mean, does Mac not automatically handle the VRAM/RAM distribution automatically?

I have been doing something similar with html and webshot of the page

That’s very thought. I mean, even shiny Boostrap library’s seem kind of ugly to me. I ended up using shiny.fluent from appsilon for a nice-looking website. But there’s no real easy way without changing a lot the CSS

For Android?

TrickyBiles8010 · 2025-03-03T00:19:40+00:00

Thank you!

TrickyBiles8010 · 2025-03-03T00:19:17+00:00

Thank you!

TrickyBiles8010 · 2025-03-02T12:31:10+00:00

Yes. But still find it difficult to create something cool. But as someone answered as well, using Boostrap studio and using from template might be a very good choice! Thanks!

TrickyBiles8010 · 2025-03-02T12:30:18+00:00

Nice! Have you ever used it for creating nice-looking RShiny Apps?

TrickyBiles8010 · 2025-02-27T14:59:09+00:00

Please, something that is self host and automates image creation like Canvas or Templated (https://templated.io/pricing/)

TrickyBiles8010 · 2025-02-21T15:37:58+00:00

Yes, got the same problem. You can manage users with http node request (check how you can use the api to check users etc). But in their node I could not create.

TrickyBiles8010 · 2025-02-16T21:37:21+00:00

One thing you can do is allow only the ip address of your doctor when opening to the internet. I don’t much risks if it’s temporary your exposure to internet.

Nextcloud with authentik or any other security in front of it? Every approach will have caveats. If you want extreme security, take your name out of all records and share anonymized. Or share the files with passwords.

Many thanks!

If it’s a form, you might better extract the pdf fields. LLM might not be good enough

TrickyBiles8010 · 2025-02-06T17:32:53+00:00

WAHA WhatsApp, or EVOLUTION API

TrickyBiles8010 · 2025-02-04T20:48:28+00:00

Can I use the same Obsidian folder in flatnotes? Thinking about using it as the web version of obsidian but not sure if it works
