Nova Reactive Field

An extension of the codebykyle/calculated-field package (github), with more field types.

Unlike codebykyle/calculated-field, each field has listening and broadcast capabilities:

• To broadcast, use ->emit(string $event)
• To listen, first specify th event to listen for ->on(string|string[] $event) then handle it with ->handle(callable $callback).

Example usage can be found in Example.php.

For the listening field, the callback function in ->handle(callable $callback) is provided with a collection of values from broadcasters (Collection $values), then calculates and returns a new value for the listener field.

The only field that has extra is the ReactiveBelongsTo field.

It's a neat idea inspired by manmohanjit/nova-belongs-to-dependency It has a dependsOn(string fieldName) function that filters related resources (for the belongsTo select-field), based on the value(s) returned from ONE broadcaster.
