Performance

Dash Express takes care of improving performance instead of you, here are the ways built in by default:

Using callbacks on the client side

Most of the callbacks are implemented on the client side, not on the server in Python.

Partial property updates

Graph creation functions are automatically converted to Patch objects, only updating the parts of a property that you want to change

Caching

Dash Express uses the Flash-Caching library, which stores the results in a shared memory database such as Redis, or as a file in your file system.

Data Serialization with orjson

DashExpress uses orjson to speed up serialization to JSON and in turn improve your callback performance
