Hi I am relatively new to developing apps using dash.  
I am using JupyterDash(). I am unable to see the updates on the web browser after making a change and saving and refreshing the browser.  
This link ([My web app doesnt update in my browser when i make any changes to the code](https://community.plotly.com/t/my-web-app-doesnt-update-in-my-browser-when-i-make-any-changes-to-the-code/25047)) suggested to changing the port, but then every time I make an update I have to change the port, which I think is not the correct way of doing this.  
Could you please help. Here is a minimal example I am trying at the moment.  
Thanks

app = JupyterDash( **name** )

app.layout = html.Div([  
html.H1(‘My Title’),  
html.P(“Select a date:”),  
dcc.Dropdown(  
id=‘date’,  
options=[‘2022-11-30’, ‘2022-12-31’],  
value = ‘2022-11-30’  
# inline=True  
),  
dcc.Graph(id=“graph”),  
])

app.css.config.serve\_locally = True  
app.scripts.config.serve\_locally = True

if **name** == “ **main** ”:  
app.run\_server(debug=True, host=“0.0.0.0”, port=“8059”, use\_reloader=False)

Welcome to the forums, @dhunfini.

I assume you are using dash in jupiter? There is no need anymore for `JupyterDash` starting with dash v2.11.0.

Concerning your code snippet, this code works on my side.

```python
import dash
from dash import Dash, html, dcc

app = Dash( __name__ )

app.layout = html.Div(
    [
        html.H1('My Title'),
        html.P('Select a date:'),
        dcc.Dropdown(
        id='date',
            options=['2022-11-30', '2022-12-31'],
            value = '2022-11-30'
            # inline=True
        ),
        dcc.Graph(id='graph'),
    ]
)

app.css.config.serve_locally = True
app.scripts.config.serve_locally = True

if __name__ == ' __main__':
    app.run_server(debug=True, use_reloader=False)

```

Thank you @AIMPED

It worked, but when I set mode =‘external’, I do not see a link for the web app.  
Is this how it would be like?
