react-cinemagraph

Generic Cinemagraph component, built for React.

The problem

You want a generic, adaptive, React-friendly, and customizable Cinemagraph-style component within your React application.

This solution

This component - react-cinemagraph!

The demo

Right here - https://jac21.github.io/react-cinemagraph-demo/

Installation

$ npm i react-cinemagraph

Usage

import React from 'react';
import { Cinemagraph } from 'react-cinemagraph';

class Demo extends Component {
  state = {
    height: 50,
    maxHeight: 100,
    fallbackImage: './demo/assets/Disco.jpg',
    fallbackImageAlt: 'Disco',
    mp4Source: './demo/assets/Disco.mp4',
    webmSource: './demo/assets/Disco.webm',
    effects: {
      grayscale: 1,
      sepia: 0.35,
      blur: 2,
      contrast: 1.1
    }
  };

  render() {
    return (
      <div>
        <Cinemagraph
          height={this.state.height}
          maxHeight={this.state.maxHeight}
          fallbackImage={this.state.fallbackImage}
          fallbackImageAlt={this.state.fallbackImageAlt}
          mp4Source={this.state.mp4Source}
          webmSource={this.state.webmSource}
          effects={this.state.effects}
        />
      </div>
    );
  }
}

Alternatively (and preferably, if using webpack):

import React from 'react';
import { Cinemagraph } from 'react-cinemagraph';

import discoJpg from './assets/Disco.jpg';
import discoMp4 from './assets/Disco.mp4';
import discoWebM from './assets/Disco.webm';

class Demo extends Component {
  state = {
    height: 50,
    maxHeight: 100,
    fallbackImage: discoJpg,
    fallbackImageAlt: 'Disco',
    mp4Source: discoMp4,
    webmSource: discoWebM,
    effects: {
      grayscale: 1,
      sepia: 0.35,
      blur: 2,
      contrast: 1.1
    }
  };

  render() {
    return (
      <div>
        <Cinemagraph
          height={this.state.height}
          maxHeight={this.state.maxHeight}
          fallbackImage={this.state.fallbackImage}
          fallbackImageAlt={this.state.fallbackImageAlt}
          mp4Source={this.state.mp4Source}
          webmSource={this.state.webmSource}
          effects={this.state.effects}
        />
      </div>
    );
  }
}

Props

Every required and optional prop from react-cinemagraph (height, maxHeight, fallbackImage, fallbackImageAlt, mp4Source, webmSource, effects)

height

Type: Number (Is Required)

Height of Cinemagraph in VW units relative to window's width.

maxHeight

Type: Number (Is Required)

Maximum height of Cinemagraph in VH units relative to window's height.

fallbackImage

Type: String

File path for the fallback image to be rendered on unsupported browsers.

fallbackImageAlt

Type: String

'alt' property for the aforementioned fallback image.

mp4Source

Type: String

File path for the Cinemagraph's mp4 file-type video source

webmSource

Type: String

File path for the Cinemagraph's WebM file-type video source

effects

Type: Object

CSS filter values to apply to the Cinemagraph's video in a composable way.

Supported keys:

• blur
• brightness
• contrast
• dropShadow
• grayscale
• hueRotate
• invert
• opacity
• saturate
• sepia

Examples:

effects={{
  grayscale: 1,
  sepia: 0.35,
  blur: 4,
  contrast: 1.1,
  hueRotate: 45,
  dropShadow: '0 8px 24px rgba(0, 0, 0, 0.25)'
}}

Numeric blur values are treated as pixels, numeric hueRotate values are treated as degrees, and the remaining numeric effect values are passed through directly.

Deprecated props

isBlackAndWhite, isSepia, and isBlurred still work for backwards compatibility, but they are deprecated in favor of effects. If both are provided, explicit effects values win.
