Here's an elementary example of using dstack. The application takes real-time stock exchange data from Yahoo Finance for the FAANG companies and renders it for a selected symbol.
Here's the Python code that you have to run to make such an application:
from datetime import datetime, timedelta
import dstack.controls as ctrl
import dstack as ds
import plotly.graph_objects as go
import pandas_datareader.data as web
def get_chart(symbols: ctrl.ComboBox):
start = datetime.today() - timedelta(days=30)
end = datetime.today()
df = web.DataReader(symbols.value(), 'yahoo', start, end)
fig = go.Figure(
data=[go.Candlestick(x=df.index, open=df['Open'], high=df['High'], low=df['Low'], close=df['Close'])])
return fig
app = ds.app(get_chart, symbols=ctrl.ComboBox(["FB", "AMZN", "AAPL", "NFLX", "GOOG"]))
result = ds.push("faang", app)
print(result.url)If you run it and click the provided URL, you'll see the application:
