Sharing Data between Multipage App Pages - Plotly Dash

This tutorial will show you how to share data between pages of a multipage app. There are 3 ways to share data in a Dash app:

1. in the app user's browser (dcc.Store),
2. on the disk (e.g. databases),
3. server-side memory (e.g. Redis). We will focus on the dcc.Store, where data shared should not exceed 10mb.
