Hello!
The dcc.Store component is a first-class citizen in Dash, and I wanted to write a tutorial covering how it works, how to debug it, and the best practices (at least the ones I know!).
I think it still lacks examples (such as bad uses of dcc.Store, like storing a huge DataFrame), but I figured that could be worth another blog post. 
Let me know what you think about it and if I should elaborate more on some parts.
