This is a documentation issue not a framework issue. For a long time you do client side storing of data with dcc.Store: https://dash.plotly.com/dash-core-components/store https://dash.plotly.com/dash-core-components/store For server side storing of data you should use a simple DB store like Redis. Dash has really matured in the last 2 years and you can actually push the envelope in a lot of places now without having to do incredibly hacky things. The documentation though still isn't great...
