ReactCardFlip

React Card Flip is allows you to use the card flipping animation. Credit for the CSS goes to David Walsh.

Demo & Examples

Live demo: Demo

To build the examples locally, run:

yarn install
yarn start

Then localhost:8080 should open in a browser. If not you can go to that directly.

Installation

The easiest way to use react-card-flip is to install it from NPM with the command:

yarn add react-card-flip

You can also use the standalone build by including lib/react-card-flip.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

Usage

To use this component, first import ReactCardFlip:

import ReactCardFlip from 'react-card-flip';

and then provide it with two child components with keys marked front and back so that the component can tell which component should be in the front and which component should be in the back.

This component only allows for manual card flip so make sure to include a tag that has an onClick handler for each side of the card.

The animation itself will be controlled by the prop isFlipped. Use this to control whether to show the front or the back of the card.

class App extends React.Component {
  constructor() {
    super();
    this.state = {
      isFlipped: false
    };
    this.handleClick = this.handleClick.bind(this);
  }

  handleClick(e) {
    e.preventDefault();
    this.setState(prevState => ({ isFlipped: !prevState.isFlipped }));
  }

  render() {
    return (
      <ReactCardFlip isFlipped={this.state.isFlipped}>
        <YOUR_FRONT_CCOMPONENT key="front">
          This is the front of the card.
          <button onClick={this.handleClick}>Click to flip</button>
        </FrontComponent>

        <YOUR_BACK_COMPONENT key="back">
          This is the back of the card.
          <button onClick={this.handleClick}>Click to flip</button>
        </BackComponent>
      </ReactCardFlip>
    )
  }
}

YOUR_FRONT_CCOMPONENT and YOUR_BACK_COMPONENT here are meant to be the two components that you plan to use for the card, one for the front of the card and one for the back of the card.

The most important part is providing the key props with the values front and back to your two components so that ReactCardFlip can differentiate between the two components. key="front" tells ReactCardFlip to use that component as the front of the card. Similarly, key="back" tells ReactCardFlip to use that component as the back of the card.

Properties

Props	Type	Description	Default
isFlipped	bool	False to show the front of the card, true to show the back	undefined
flipSpeedBackToFront	number	The speed of the flip animation when the card flips from back to front, the higher the number the slower the flip animation	0.6
flipSpeedFrontToBack	number	The speed of the flip animation when the card flips from front to back, the higher the number the slower the flip animation	0.6
infinite	bool	False to rotate in opposite directions on both sides of the card, true to rotate in the same direction	false

Development (`src`, `lib` and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run yarn start. If you just want to watch changes to src and rebuild lib, run yarn watch (this is useful if you are working with npm link).

Testing

To run tests for this project run one of the following commands:

yarn test - Runs tests then exits
yarn test:watch - Runs tests in watch mode
yarn test:coverage - Runs tests and creates a coverage report
