React Prop

One of the key ideas behind Reactive Search and Reactive Maps is the reactive design pattern, which allows defining how a component reacts to changes in the states of the sensors. This allows almost all ReactiveSearch components to watch each other and update their data reactively. For example, a SingleList component can update its data based on the search term in a DataSearch component.

Usage

<ReactiveMap
    ...
    react={{
      "and": "citySensor",
      "or": "searchSensor"
    }}
>

Props

  • react Object
    react prop is available in components whose data view should reactively update when on or more dependent components change their states, e.g. ReactiveMap, ReactiveList.

    • key String
      one of and, or, not defines the combining clause.

      • and clause implies that the results will be filtered by matches from all of the associated component states.
      • or clause implies that the results will be filtered by matches from at least one of the associated component states.
      • not clause implies that the results will be filtered by an inverse match of the associated component states.
    • value String or Array or Object

      • String is used for specifying a single component by its componentId.
      • Array is used for specifying multiple components by their componentId.
      • Object is used for nesting other key clauses.

An example of a react clause where all three clauses are used and values are Object, Array and String.

<ReactiveMap
  ...
  react={{
    "and": {
        "or": ["CityComp", "TopicComp"],
        "not": "BlacklistComp"
    }
  }}
/>

Here, we are specifying that the map’s UI should update whenever one of the blacklist items is not present and simultaneously any one of city or topics matches.
