Hey everyone! I created a custom component that triggers Streamlit to rerun on a user-specified interval. I was running across a lot of Streamlit apps using infinite loops, and while we can allow it in a script, I think this custom component will alleviate a lot of the stress of running an infinite…

Hi, Actually the component loading is fine. Currently my issue is dependency on the browser. I have to keep it open and hence my laptop can’t shut down as well. Is there a way to open the tab from a terminal background.

[image] kmcgrady: GitHub - kmcgrady/streamlit-autorefresh: An autorefresh component for Streamlit apps I want to update my app on Streamlit every 30 minutes. This update includes calling an API to update the dataset on server side. For now I should check something like below when user enters…

In that case you would do something like the following st_autorefresh(interval=30*60*1000, key="api_update") That way the Streamlit app does not need a loop or time.sleep to keep updating.

But I think with this, user should stay on that page. I need the update should be run server side every 30 minutes. Is this possible?

@MAmrollahi So there’s two solutions I can think of: an easy one, and a harder one. The easiest one is using st.experimental_memo with a ttl . This will allow every new rerun past a certain time to extract the contents. Depending on how “up to date” the frontend has to be, you can use autorefresh e…

Hi @kmcgrady , I saw this and wanted to use it for my app, which requires a live update every few minutes. However, I get this message when I try to run your trivial example. [image] Any ideas on how to bypass this? Thanks!

Hi @kmcgrady I am getting this error when using autorefresh. My frequency is 1 sec. The autorefresh works well for a while, then it starts giving the following error about “too many open files”, with the file name being the url that I have open. If it matters any, I am using the “pages” feature of…

Hey @HHest Hmmm, based on the error you are providing, it seems like it’s a web socket problem. Let me see if my colleague knows more what’s going on.

Thank you very much @kmcgrady . I’ll try to replicate with a small example as well.
