Cubit

Cubit is a simple state container with public mutation helpers.

import { Cubit } from '@blac/core';

class CounterCubit extends Cubit<{ count: number }> {
  constructor() {
    super({ count: 0 });
  }

  increment = () => this.emit({ count: this.state.count + 1 });
  decrement = () => this.update((state) => ({ count: state.count - 1 }));
  reset = () => this.patch({ count: 0 });
}

Methods

• emit(newState)
• update(fn)
• patch(partial) (shallow merge for object state only)

patch() throws if the current state is not an object.
