Filter

Purpose

The Filter component contains all of the complexity for configuring and rendering the supported @appbaseio/reactivesearch filter components.

Usage

Most implementations will pass the filter object directly from the Filters component as seen in the example below however you could replace that with the useFilter hook for this.

If a render method is not provided a built-in component for that filter will be rendered.

Basic

import React from "react";
import { Filters } from "@usereactify/search";

import { ExampleFilterList } from "./ExampleFilterList";
import { ExampleFilterRange } from "./ExampleFilterRange";
import { ExampleFilterSlider } from "./ExampleFilterSlider";

export const Component: React.FC = () => {
  return (
    <Filters
      render={(filters) => filters.map((filter) => (
        <Filter
          filter={filter}
          renderFilterList={ExampleFilterList}
          renderFilterRange={ExampleFilterRange}
          renderFilterSlider={ExampleFilterSlider}
        />
      )}
    />
  );
};

ExampleFilterList

import React from "react";

export type ExampleFilterListProps = React.ComponentProps<
  NonNullable<FilterProps["renderFilterList"]>

export const ExampleFilterList: React.FC<ExampleFilterListProps> = (props) => {
  return (
    <div className="rs__filter">
      <h3 className="rs__filter__name">{props.filter.name}</h3>
      {props.filter.displayView === "list" ? (
        <ExampleFilterListList {...props} />
      ) : null}
      {props.filter.displayType === "single" &&
