Would you like to understand the main limitations of the Streamlit Python library for building data web apps, before picking it up for a project?
In this video, I'll cruise through 5 obstacles that regularly come back within the community and multiple ways/hacks/techniques to work around those limits. You'll find out:
- how to hack markdown and iframe to style your app
- if it's possible to alter the Streamlit rerun event loop and Tornado Backend server
- thoughts to build a desktop app from your Streamlit app
- where is the ipywidgets integration into Streamlit at
After you watch me show you all those advanced techniques, you should have a good idea of Streamlit's limits and ways to go around Streamlit's "run from top to bottom philosophy" to meet your ends.

Your videos, specially your Streamlit react component tutorial, have inspired me to dive deeper in the universe of JavaScript. I am planning to go the route of learning React.js, Next.js and TailwindCSS. Do you think it's a wise option to develop more large scale applications with authentication and data viz JS libraries? What path would you recommend?

@andfanilo 4 ай бұрын

Eheh :) I feel the deeper insight of my channel is to not be scared of JS and try it at least once One day at work, I was "attacked" by a senior architect telling me he would never put Dash code in production because he couldn't trust any Python framework generating React code. That's the day I started working on 2 Vue.js projects and going into the JS journey. Maybe it is still subconscious in my videos 😂 Maybe not "large-scale", but I do think it's good to build a small SPA in full JS with 2-3 input + graphs and some CSS animations at least once in your life (not FastAPI serving Next.js, but going the full Node.js route). Then you get a grasp of how Streamlit/Dash generate React code, if you need to explain architects how those can be optimized. Ultimately you should feel comfortable with Python libraries like Solara or NiceGUI, or even spin your FastAPI serving HTMX/Alpine.js or SvelteKit/Next.js, for tools that are more "flexible", less "black-box magic" than Streamlit React/Next.js is a great option, React has so many great libraries. Yet if I were to do a new side project for a video right now, I'd look at Svelte/SvelteKit, the barrier of entry looks far lower and closer to HTML/CSS/JS than React is, so you "should" get at quicker results. Plus you can write Svelte components in both Streamlit and Gradio, a good win. I'd keep Tailwind for CSS.

I actually wanted to know the exact the about the libraries you shown in the video. Also I understood all of it, as I have developed in streamlit for a year them switched to nicegui also got the honour to provide a contribution to the library component of nicegui, have used panel little bit. But I am a bit disappointed you missed out flet and streamsync. These libraries deserve more love I believe. Still don't feel like God level status but ya some of my peers do say that while referring to me, but I am also hungry for even more more coding knowledge. 😅

@andfanilo 4 ай бұрын

@@pranitrock i did talk about flet at the end of the video 😁 I also missed on streamsync , taipy, chainlit, there are so many libraries to read about, try, compare, contribute to… so we must keep learning and pushing the boundaries of Python web apps! I personally don’t consider myself a god of Python ahah, I’m just a curious tech saavy user who loves to produce videos about my experiences :) Glad you’re enjoying the journey with NiceGUI. It’s a library I wanted to talk about in a video for a while, looking forward to have time to do one about it. If I could I would do a separate video for each of those libraries, but eh time is scarce 🤣

Insightful. I tried to convert my streamlit app to desktop using electronJs but it seems like it doesn't support threading or queue. Similarly, I would appreciate if you could suggest some framework/libraries with modern ui components (like that of streamlit) for quick desktop app, which can be converted to executable file.

@andfanilo 4 ай бұрын

Hey, I've recommended Flet ( flet.dev/ ) in the video, that may be the one with the most "modern" look and uses Flutter SDK instead of PyInstaller to package. That *may* work around the threading/queue part The more native libraries like PySimpleGUI/Gooey/PyQT5 create executables that look pretty much like you classical Desktop app, but maybe if you're in a rush they will be helpful for you Packging a Python web app as an executable is an absolute pain, which is why I prefer to recommend deploying on an on-prem server or in the Cloud and send the URL to your colleague...I know it's not always possible but really, packaging web to desktop is a much worse experience 😕

The more you dig deep in Streamlit more dead ends you will find. It is not for any serious stuff, even thinking of using websocket as data pipe in Streamlit is prohibited .

What about mobile apps? If I want to have a multi/cross-platform code, is streamlit suitable? or do you recommend another similar tool/framework?

@andfanilo Ай бұрын

Streamlit builds a responsive web app, so you can access the url from a smartphone and the app will adapt to the screen size But it’s not a native mobile app. The only Python alternative I heard about for cross platform is Flet, though I have not tried it yet If you do try it, I’d love your feedback here!

Can you confidently sell Streamlit apps (eg. Llm Chat Rag App) to clients or would you more lile switch to an alternative?

@andfanilo 4 ай бұрын

I've seen multiple manual monetization strategies: - Stripe integration + Google Auth with st-paywall github.com/tylerjrichards/st-paywall (could probably build an easier way through Gumroad License keys for example) - embedding a Streamlit app in an of a paywalled website, or as an external web service behind a Javascript paywall - deploying a private Streamlit app to Streamlit Cloud and adding authorized email accounts of people that paid - just selling an app as a final product of a paid consultation, deployed on their servers or in your own Cloud project with limited access But so far no native answer for this. I do think the other Python solutions require as much stitching as Streamlit. Though managing subscription might be easier in other solutions like Dash, they will require a bit of coding I should write this down as a video idea for later 🤔

I was trying create a streamlit app to plot a 2D slice of a brain region and I want to add and delete points from that 2D slice respresentation. Is it possible through the streamlit app to make it interactive? Like the user can click on any co-ordinate and add a point or click on an existing point and delete it? Is it possible or should I use some other app? Please can you guide me?

@andfanilo 13 күн бұрын

Hello! I think it would be possible with drawable canvas, but I wonder with the switching between multiple 2D slices + manipulating add/deletion for each 2D slice level and storing all point info in session state, all with Streamlit rerunning on every interaction, if Streamlit is the best bet... Haven't tried it, but usually I check Gradio after Streamlit before checking Panel/Dash/Solara...Gradio seems to let you access clicked point coordinates of the image eventdata with the Image.select() method natively ( github.com/gradio-app/gradio/pull/3786 & github.com/gradio-app/gradio/blob/main/demo/image_selections/run.py ) and you can edit the slice after reacting to the event. I can't try it yet, because I'm out of home for a few days to film a corporate event, but this right now would be my first try. I'll let you know if I stumble on another idea. I hope my writing while travelling makes a bit of sense :)
