How to Convert a Streamlit App to an .EXE Executable

Yuichiro (a.k.a whitphx, also the creator of streamlit-webrtc) is a Streamlit Creator who singlehandedly implemented stlite, a port of Streamlit to WebAssembly powered by Pyodide/ This enables us to use Streamlit in a web page without installing Python locally.
With this + Electron, it is possible to build a Desktop Executable out of this Pyodide-powered project! This currently makes it the easiest way, literally 3 commands, to bundle a Streamlit project into an executable to send to your friends and family!

Hey y’all! One fix that made the altair issue work for me was -> running the following in the powershell visual studio code command (windows): ~> npm outdated And then ~> npm update Please note, there’s no need for the altair

[@andfanilo]

Thanks for sharing, lemme pin your comment for some time :)

​@@andfanilo !!!!!!!QUICK UPDATE!!!!!!! [[[How to create a Streamlit desktop app]]] Create the following package.json file to start a new NPM project. Edit the name field. { “name”: “xxx”, “version”: “0.1.0”, “main”: “./build/electron/main.js”, “scripts”: { “dump”: “dump-stlite-desktop-artifacts”, “serve”: “cross-env NODE_ENV=production electron .”, “pack”: “electron-builder --dir”, “dist”: “electron-builder”, “postinstall”: “electron-builder install-app-deps” }, “build”: { “files”: [“build/**/*”], “directories”: { “buildResources”: “assets” } }, --------------------------------------------------------------- “devDependencies”: { “@stlite/desktop”: “^0.25.0”, “cross-env”: “^7.0.3”, “electron”: “23.1.1”, “electron-builder”: “^23.6.0” } } Here you should change it to the following: ->->->->->->->->->->->->->->->->->->->->->-> }, “devDependencies”: { “@stlite/desktop”: “^0.31.0”, “cross-env”: “^7.0.3”, (check your version, by running npm show cross-env in the command) “electron”: “23.1.1”, (check your version - for me it was 23.1.1) “electron-builder”: “^24.4.0” (depending on the version) } } 2. Run npm update (instead of npm install). 3. Create streamlit_app directory. o Any directory name can be used here. 4. Create streamlit_app/streamlit_app.py. o Change the directory name if you used a different name in the previous step. 5. Write your Streamlit app code in streamlit_app/streamlit_app.py. o The file name streamlit_app.py is not configurable now. 6. Optionally, you can add more contents in the directory, including pages/*.py for multi-page apps, any data files, and so on. 7. Run npm run dump streamlit_app - -r requirements.txt (the requirements file includes like the following: streamlit plotly pandas 8. Run npm run serve (or similar to the video -servewindows) 9. Run npm run dist or yarn dist for packaging. o This command bundles the ./build directory created in the step above into application files (.app, .exe, .dmg etc.) in the ./dist directory. To customize the built app, e.g. setting the icon, follow the electron-builder instructions.

Tired this out my self a few weeks back and it really is a great step forward! Unfortunately, I couldn’t persist a local database due to Electron security restrictions. I also tried MongoDB and Firebase for cloud storage, but I believe the imports included C-extensions, preventing it from working. Great video by the way 👍🏼

[@andfanilo]

Thanks for mentioning. I had seen an issue on this (github.com/whitphx/stlite/issues/463), I just forgot to script this and the general issues on interacting back with the local filesystem 🥲 . Hope other viewers will catch your comment. And that sucks for the external databases, we'll have to wait for the C-extension packages...I'm generally hopeful the Python with WASM ecosystem will keep growing with the efforts on PyScript, and this solution is still easier to setup than PyInstaller/PyOxidizer, so fingers crossed Have a nice day, thanks for watching!

Nice video. Does this process work for a multipage streamlit app that uses several other packages like streamlit extras, streamlit drawable canvas, st_aggrid, tensorflow, some pre-trained deep learning based libraries/modules etc?

[@andfanilo]

Thanks for the support! It works until you use a Python package that does not have a Pyodide counterpart. I haven't tested Tensorflow but I don't think this one would work for example. It unfortunately then becomes a game of testing each package...if you're doing a really complex app with a lot of dependencies, maybe you're better off hosting it in the Cloud or on an on-premise server, until the Pyodide ecosystem gets bigger :/

[@DrSIyer]

Great tutorial!! Thank you ! Will a streamlip app that web-scrapes live data from websites (using requests, beautifulSoup etc), still work when converted to a standalone executable?

[@andfanilo]

Thanks for the support! The list of Pyodide maintained packages can be found here pyodide.org/en/stable/usage/packages-in-pyodide.html which beautifulsoup is in, and to that you'll have to add all pure Python packages. I believe requests is pure python but I haven't tried, maybe you can try packaging a very small requests-beautifulsoup4 app to test it out If you do let us know :) I'd love to hear back, that looks like a very interesting use case!

Hey! I know this issue is tracked somewhere, let me find it...ah, github.com/whitphx/stlite/issues/463 As you say, I don't think it's possible to interact with the user computer for now.

Hey! From memory you're stuck on Python 3.10 for now, I read this somewhere on the stlite docs but can't find the link right now :/ I know Pyodide and Streamlit independently integrated Python 3.11 end of January. Maybe you can ask on github.com/whitphx/stlite/issues for a 3.11 version. Have a nice day!

[@ege.the.engineer]

Unfortunately this doesn't work if your code contains modules/packages that written other languages than python, and/or if it can't find .whl package of that module my issue was the first one. I have bunch of module that written in other languages such as c++ etc on my python-streamlit project. Any suggestion for this will be appreciated.

[@andfanilo]

Hello! Yes, Pyodide clearly won't be able to manage any of those non pure-python packages, as you may have seen in other comments :/ you may have more luck with Pyinstaller but I find packaging Streamlit with Pyinstaller to be extra painful.. Unfortunately, I don't think it will be easy to install multiple non-python binaries on non tech-saavy people's computers, and for now my preferred way of doing would be to Dockerize the app or install it yourself on a private server/in a VM in the cloud and provide an URL to your audience. If I find any other easy way I'll write it down in a community post Have a nice day!

[@maxlgemeinderat9202]

They are also preparing for Snowflake Summit in April, which will come with some more announcements I think (I'm not in the dev team, they don't tell me those kinds of secrets ^^).

Hey! shoot, I think an earlier viewer commented the same issue if you scroll in the comments :/ I'm going to copy part of the answer here. There is a fix going on with github.com/streamlit/streamlit/pull/6618 which should enable Altair 5 to work with Streamit when merged in around 2 weeks I think... unfortunately Altair 5 is installed by default by stlite and conflicts with the current altair.vegalite.v4, and you can't downgrade it So I think you'll have to wait for 2 weeks, or ask the stlite developer to release a version with a downgraded version of altair (which I don't honestly think he will, but we never know).

Hey! I may have forgotten to mention in the video...you can't install a newer version of Streamlit in stlite (there's a pyodide issue preventing users to install a newer version of a package), so the version of stlite hardcodes the version of Streamlit. For now you may have to remove Streamlit for the list of requirements.txt.

Hi, Great tutorial. I have a request. I built an app on streamlit and now my UI team has built an interface on React. Now how do I integrate my streamlit app into UI? like how to create API endpoints? Please make some video on this. It will be of great help _/\_ .

[@andfanilo]

Hey there! I'm not totally sure I understood your question, so sorry if I miss the mark. From what I understood I imagine two ways to integrate your Streamlit app into React. They revolve around the fact that Streamlit works over the Tornado Python webserver 1. stlite is Serverless Streamlit, it detaches Streamlit UI from Tornado, so for Streamlit code that doesn't use more complex Python packages, you can integrate Streamlit code in HTML directly in a new React route. It sounds easy, but there are quite some limitations if you're using packages like Pandas pyodide.org/en/stable/usage/packages-in-pyodide.html 2. Otherwise, you'll have to host your Streamlit + Tornado somewhere (Streamlit Cloud, HF Spaces, your own platform) and your app in a HTML page in your React app as a separate route or in an existing route (one example docs.streamlit.io/streamlit-community-cloud/share-your-app/embed-your-app if your app is on Streamlit Cloud). Note that your Streamlit and React app can't easily pass information, you won't be able to get Streamlit slider variable from your React app, Streamlit is fully embedded and independent Hope this helps a little; have a nice day, Fanilo

Damn this video is a bit old already, I'll probably do a slower version in the future behind a paywall to keep it updated The most detailed tutorial you'll have for this is github.com/whitphx/stlite/tree/main/packages/desktop in the meantime (npm is installed at the same time as you install nodejs)

[@abdulrahmansabri4547]

great video as always sir. I tried your method but I get an error in the step " npm run dump streamlit_app ". The error is : ModuleNotFoundError: The module 'micropip' is included in the Pyodide distribution, but it is not installed. Could you help me with this error please

[@mikhwan97]

I also experience this issue. Anyone able to solved this?

[@edustemlab]

Use the requirements.txt method

Glad you liked it :D

Didn't work for me. It got stuck in Install [3 .whl files ] while trying "npm run dump streamlit_app -- -r requirements.txt"

[@andfanilo]

Ah shoot 😯 for better support you could open an issue on github.com/whitphx/stlite/issues with your environment and dependencies you're trying to have added. The dump is mostly copying files to tmp directories and downloading Pyodide versions of dependencies from the web, so one of those 2 may be stuck...

I got some problems, when I use "npm serverwindows" app runs correctly but my download buttons don't work. I tried to build an app anyway. When I run exe I get this error: ModuleNotFoundError: No module named 'altair.vegalite.v4'

Hey! shoot, I think an earlier viewer commented the same issue if you scroll in the comments :/ I'm going to copy part of the answer here. There is a fix going on with github.com/streamlit/streamlit/pull/6618 which should enable Altair 5 to work with Streamit when merged in around 2 weeks I think... unfortunately Altair 5 is installed by default by stlite and conflicts with the current altair.vegalite.v4, and you can't downgrade it So I think you'll have to wait for 2 weeks, or ask the stlite developer to release a version with a downgraded version of altair (which I don't honestly think he will, but we never know). Sorry :/ EDIT: Or check the pinned comment for a quick workaround

Oh that's odd...do you have more logs before this line? I would suggest putting the full logs and eventual smaller reproducible project on github.com/whitphx/stlite/issues, easier to debug than in KZbin comments :/

[@ErenBoi-gz3jz]

hello @gekacrazy, did you find any solution because I am also facing the same issue. Thank you in advance.

[@nicolo1140]

Same here 😭. Did you find any solutions?
