This package has been deprecated

Author message:

package has been renamed to react-optimized-filter, use the new package for future releases

@bsara/react-filter

A simple React component used for array filtering.

NOTE: This component uses a for-loop for filtering rather than the native Array's filter function. This means that filtering will be more performant (see jsperf test for details).

Usage

import React from 'react';
import Filter from '@bsara/react-filter';

export default function MyComponent(props) {
  return (
    {/* ... */}

      <Filter
        items={props.items}
        predicate={_predicate}
        predicateArg={props.predicateArg}
        render={(filteredItems) => (
          // Render filtered items...
        )} />

      {/* ...or... */}

      <Filter items={props.items}
              predicate={_predicate}
              predicateArg={props.predicateArg}>
        {(filteredItems) => (
          // Render filtered items...
        )}
      </Filter>

    {/* ... */}
  );
}

function _predicate(item, index, predicateArg) {
  // Determine if item should be included in filtered list...
}

Props

• items ?Array

  Array of items to be filtered and passed to render prop.

• render(filteredItems) or children(filteredItems) !Function - REQUIRED

  Render function (or function as child) called after items filtering is complete.

• predicate(item, itemIndex[, predicateArg]) !Function - REQUIRED

  Function to be called for each item in items. Return true to include item in the resulting filtered items list. Return false to exclude item from the resulting filtered items list.

• predicateArg ?*

  Parameter to be passed as an extra argument in predicate function. This prop is not required and is provided solely for convenience.

• skip ?Boolean

  When true, skips filtering and the value of items prop will be passed to render, unsorted. This is useful in the case where sorting may only be conditionally needed.
