Hi toddabrams,
I’ve just recently started with VS code and the debugger. I am not sure how to do it directly with dash, but i’ve managed to be able to use the default Flask debugger on a dash app by just pulling out the flask object like this for the first example from here, placed in a file called app.py :
import dash
import flask
import dash_core_components as dcc
import dash_html_components as html
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
f_app = flask.Flask(__name__)
app = dash.Dash(__name__, external_stylesheets=external_stylesheets, server=f_app)
app.layout = html.Div(children=[
html.H1(children='Hello Dash'),
html.Div(children='''
Dash: A web application framework for Python.
'''),
dcc.Graph(
id='example-graph',
figure={
'data': [
{'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'},
{'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name': u'Montréal'},
],
'layout': {
'title': 'Dash Data Visualization'
}
}
)
])
if __name__ == '__main__':
app.run_server(debug=True)
here is how my default flask debugger looks:
{
// Use IntelliSense to learn about possible attributes.

"version": "0.2.0",
"configurations": [
{
"name": "Python: Flask",
"type": "python",
"request": "launch",
"module": "flask",
"env": {
"FLASK_APP": "app.py",
"FLASK_ENV": "development",
"FLASK_DEBUG": "0"
},
"args": [
"run",
"--no-debugger",
"--no-reload"
],
"jinja": true
}
]
}
That seems to work well for me, also enabling debugging of callbacks when they are clicked etc.
But as i said, I’ve only played with it for a couple of minutes.
