The dash-extensions package is a collection of utility functions, syntax extensions, and Dash components that aim to improve the Dash development experience. Here is a brief overview,

• The enrich module, which contains various enriched versions of Dash components
• A number of custom components, e.g. the Websocket component, which enables real-time communication and push notifications
• The javascript module, which contains functionality to ease the interplay between Dash and JavaScript
• The logging module, which makes it a breeze to route logs to your Dash UI
• The events module, which facilitates event flows in Dash
• The pages module, which extends the functionality of Dash Pages
• The snippets/utils/validation/streaming modules, which contain a collection of utility functions (documentation limited to source code comments)

The enrich module enables a number of transforms that add functionality and/or syntactic sugar to Dash. Examples include

• Making it possible to avoid invoking a callback if it is already running via the BlockingCallbackTransform
• Improving app performance via the ServersideOutputTransform
• Automated serialization/deserialization of Pydantic models via the BaseModelTransform

to name a few. To enable interactivity, the documentation has been moved to a separate page.

NB: The 2.0.0 version introduces a number of breaking changes, see documentation for details.
