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

<data-search
    ...
    :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.

<data-search
  ...
  :react=`{
    "and": {
        "or": ["CityComp", "TopicComp"],
        "not": "BlacklistComp"
    }
  }`
/>

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