[Feat] Add support for streamlit

[goncaloalves]

Is it possible to add support for Streamlit?

I think that using the components API from streamlit and a Jinja template that puts the HTML and Javascript file into one this is possible.

PyGWalker is an amazing library. Congrats for your job. I have the same issue the @goncaloalves . For me will be very useful if it could use PyGWalker together streamlit.

Hello, welcome to make an early trial of Streamlit support with

!pip install git+https://github.com/Kanaries/pygwalker.git@streamlit-dev

import pygwalker as pyg
pyg.walk(df, env='Streamlit')

UPD: the branch streamlit-dev was only for trial and has been deleted after being merged into main.

released in pygwalker>=0.1.4.9.

thank you, it seems I can only visit on localhost, but from network url, it returns error:

tornado.websocket.WebSocketClosedError
tornado.iostream.StreamClosedError: Stream is closed

Thanks for your feedback, we'll take care of it later.

I'm sorry I don't have a lot of experience with streamlit. But the problem seems to arise frequently during use.
One problem is that I'm not sure what network means. Does it mean access to streamlit that someone else has deployed, or some streamlit that is in the cloud, or some service that integrates stremlit
Is there a link to your code that you can provide, so that we can try to troubleshoot?

hi, this one it means access to streamlit that someone else has deployed,
I developed some streamlit apps so that my collegues can use it.
other elements rendered fine, only [pygwalker] not responsing correctly with regard to above error msg.
some code:

#app.py
import streamlit as st
import pandas as pd
import pygwalker as pyg
df = pd.read_csv(' ./data.csv') 
pyg.walk(df, env='Streamlit') 

then host in command line:
streamlit run app.py
the returned msg would be:

You can now view your Streamlit app in your browser.
  Local URL: http://localhost:8504
  Network URL: http://123.45.6.78:8504

---

on local host side :
say http://localhost:8504/
everything works fine.
on my other machine
http://123.45.6.78:8504
no return.,

plus:
I did not use pip install git+https://github.com/Kanaries/pygwalker.git@streamlit-dev
since it seems not working.
I simply pip isntall pygwalker

thank you!

Hello!
I did not find similar situation after many experiments.
I first turned on streamlit on my win11 machine, and the network url got the correct data.
Then I used ec2 of aws for testing, and network url was also able to obtain data correctly.
I found some of the similar bugs you mentioned on the web, and I wonder if this is a problem caused by the configuration of streamlit or some other component.

PS:
The python version of win11 is 3.10
The python version of ec2 is 3.7

@fyenne You can update the module to 0.1.6.0
