Emitting Fully Nested Python Schemas and Models with SQLModel

I ran into a problem while developing some cool tools. I had a nested Pydantic structure that I needed to migrate to SQLModel. But, I needed to retain the ability to emit fully nested schema and models -- which was lost. So, I had to write a few helper functions and models.

In the realm of modern web development and data-driven applications, managing complex data structures and their relationships can be a daunting task. SQLModel, a powerful library that bridges the gap between SQLAlchemy and Pydantic, offers an elegant solution for defining and interacting with SQL databases using Python. In this small write up, we dive into a practical demonstration of leveraging SQLModel to emit fully nested Python schemas and models. Surprisingly, this doesn't work out of the box.

Our focus is on a versatile script that illustrates how to dynamically generate and manipulate nested data structures. By defining SQLModel-based types, we can seamlessly map th

Redux WebSocket Middleware: Example

This Gist provides some code examples of how to implement WebSocket stream handling using a Redux middleware. Please be aware that this is only provided as an example and that critical things like exception handling have not been implemented.

A more complete version has been packaged, tested, and is available on GitHub as redux-websocket. This library has also been published to npm at @giantmachines/redux-websocket.

Middleware

This module represents the foundation of the middleware and implements the ideas presented above. The exported function is used during the creation of the Redux store (see the following snippet).

What happens if you tell GitHub it's JSON

{
  "hello": "world" // I want my comments!
}

Use jsonc as the language instead
