0.23.0

[buiapp]

0.23.0

Added

• Added ReactiveModel for grouping reactive state and behavior in reusable
  Python classes.
• Added field() for typed, per-instance signals with default values and
  factories.
• Added model-friendly @computed, @effect, @linked, and @resource
  decorators with support for instance methods.
• Added automatic ownership and cleanup of model effects and resources through
  ReactiveModel.dispose().
• Added constructor overrides and mixin guidance for initializing models with
  instance-specific values.

from reaktiv import ReactiveModel, computed, effect, field


class Counter(ReactiveModel):
    count = field(0)

    @computed
    def doubled(self):
        return self.count() * 2

    @effect
    def report(self):
        print(self.count(), self.doubled())


counter = Counter(count=5)
counter.count.update(lambda value: value + 1)
counter.dispose()

Improved

• Expanded type inference coverage and documentation for the new model API.
• Added practical ReactiveModel examples for application state, linked values,
  async resources, cleanup, and custom equality.
• Made documentation examples executable directly in the browser with Pyodide.

API Direction

• Lowercase callable APIs such as computed(), effect(), linked(), and
  resource() are planned to become the preferred style for future
  instantiation and decorators.
