📖 react-paging-indicators

Library of React paging indicator components that work well for carousels, rotators, slideshows or whatever else you could use a simple paging component for.

Install

Via npm:

npm install --save react-paging-indicators

Via Yarn:

yarn add react-paging-indicators

How to use

This library includes a few different components to offer you the flexibility you need for the task at hand.

pagingIndicator (HOC)

Higher order component that handles all of the core functionality for the paging indicators, maintaining the state of the current index, basic onClick handling for the indicators and setup/management of the Timer element, if supplied.

Properties

  • index:Number - Index of the active indicator. (Default: 0)

  • length:Number - Number of indicators to render. (Default: 1)

  • renderIndicators:Function - Function that takes an object and allows you to customize how the indicators are created.

Default:

const renderIndicators = function ({indicator, index = 0, keyPrefix = 'keyPrefix-', length = 0, onIndicatorClick = () => {}, progress = 1}) {
  const indicators = [];

  if (!indicator) {
    return indicators;
  }

  let i = 0;
  while (i < length) {
    indicators.push(
      React.cloneElement(indicator, {
        key: `${keyPrefix}-item-${i}`,
        progress: (i === index) ? progress : 0,
        onClick: onIndicatorClick.bind(this, i),
      })
    );
  };

  return indicators;
};
  • timer:Element - A Timer, (react-timer-wrapper), instance that is used to progress the indicator index.

  • onChange:Function - Callback fired whenever the index is changed, either via a click handler or when a Timer progresses the index. (Default: (index) => {})

Example

import React, {PureComponent} from 'react';
import {pagingIndicator} from 'react-paging-indicators';

class CustomPagingIndicator extends PureComponent {

  ...

}

export default pagingIndicator(CustomPagingIndicator);

CustomIndicator

Instead of using the pagingIndicator (HOC) to develop a custom pager, you can also use the CustomIndicator if all you want to change is the indicator element that is rendered for your pager.

Properties (Supports all props supported by pagingIndicator with the addition of...)

  • indicator:Element - An indicator element to represent each index, with the option of showing Timer progress if available. Works well with, react-indicators.

Example

import React, {Component} from 'react';
import Rotator from 'react-rotator';
import {CustomIndicator} from 'react-paging-indicators';
import FeatureCard from './FeatureCard';
import YourCustomIndicator from './YourCustomIndicator';

class SomethingWithPaging extends Component {
  render() {
    return (
      <Rotator
        indicator={(
          <CustomIndicator indicator={<YourCustomIndicator />} />
        )}
      >
        <FeatureCard>
          <h2>Feature #1</h2>
        </Feature>
        <FeatureCard>
          <h2>Feature #2</h2>
        </FeatureCard>
      </Rotator>
    );
  }
}

BarsIndicator

Component that uses a BarIndicator to represent a paging indicator and optional timing progress.

Properties

  • indicatorClassName:String - Class applied to the indicator items when rendered.

  • renderIndicators:Function - Function that allows you to override the default renderIndicators method.

  • Along with all properties available for the BarIndicator, except for progress, which is supplied via the optional Timer.

Example

import React, {Component} from 'react';
import Rotator from 'react-rotator';
import {BarsIndicator} from 'react-paging-indicators';
import FeatureCard from './FeatureCard';

class SomethingWithPaging extends Component {
  render() {
    return (
      <Rotator
        indicator={(
          <BarsIndicator color="red" />
        )}
      >
        <FeatureCard>
          <h2>Feature #1</h2>
        </Feature>
        <FeatureCard>
          <h2>Feature #2</h2>
        </FeatureCard>
      </Rotator>
    );
  }
}

Exampel w/ Timer

import React, {Component} from 'react';
import Rotator from 'react-rotator';
import Timer from 'react-timer-wrapper';
import {BarsIndicator} from 'react-paging-indicators';
import FeatureCard from './FeatureCard';

class SomethingWithPaging extends Component {
  render() {
    return (
      <Rotator
        indicator={(
          <BarsIndicator timer={<Timer duration={5000} />} color="red" />
        )}
      >
        <FeatureCard>
          <h2>Feature #1</h2>
        </Feature>
        <FeatureCard>
          <h2>Feature #2</h2>
        </FeatureCard>
      </Rotator>
    );
  }
}

More information about the Timer and its available options can be found on GitHub, react-timer-wrapper.

DotsPager

Component that uses a CircleIndicator to represent a paging indicator and optional timing progress.

Properties

  • indicatorClassName:String - Class applied to the indicator items when rendered.

  • renderIndicators:Function - Function that allows you to override the default renderIndicators method.

  • Along with all properties available for the CircleIndicator, except for progress, which is supplied via the optional Timer.

Example

import React, {Component} from 'react';
import Rotator from 'react-rotator';
import {DotsIndicator} from 'react-paging-indicators';
import FeatureCard from './FeatureCard';

class SomethingWithPaging extends Component {
  render() {
    return (
      <Rotator
        indicator={(
          <DotsIndicator fillColor="red" />
        )}
      >
        <FeatureCard>
          <h2>Feature #1</h2>
        </Feature>
        <FeatureCard>
          <h2>Feature #2</h2>
        </FeatureCard>
      </Rotator>
    );
  }
}
