⚡ Installation

yarn install react-chrono

Getting Started

Please make sure you wrap the component in a container that has a width and height.

When no mode is specified, the component defaults to HORIZONTAL mode. Please check props for all the available options.

  import React from "react"
  import { Chrono } from "react-chrono";
  
  const Home = () => {
    const items = [{
      title: "May 1940",
      contentTitle: "Dunkirk",
      contentText:"Men of the British Expeditionary Force (BEF) wade out to..",
      media: {
        type: "IMAGE",
        source: {
          url: "http://someurl/image.jpg"
        }
      }
    }, ...];

    return (
      <div style={{ width: "500px", height: "400px" }}>
        <Chrono items={items} cardHeight={300} />
      </div>
    )
  }

Vertical Mode

To render the timeline vertically use the VERTICAL mode

  <div style={{ width: "500px", height: "950px" }}>
    <chrono
      items={items}
      mode="VERTICAL"
    />
  </div>

Tree

In Tree mode the timeline is rendered vertically with cards alternating between left and right side.

  <div style={{ width: "500px", height: "950px" }}>
    <chrono
      items={items}
      mode="TREE"
    />
  </div>

Slideshow

Play the timeline automatically with the slideShow mode.

  <div style={{ width: "500px", height: "950px" }}>
    <chrono
      items={items}
      slideShow
      mode="TREE"
    />
  </div>

Props

Mode

react-chrono supports three modes HORIZONTAL, VERTICAL and TREE. No additional setting is required.

  <chrono items={items} mode="HORIZONTAL" />

  <chrono items={items} mode="VERTICAL" />

  <chrono items={items} mode="TREE" />

Timeline item Model

{
  title: "May 1940",
  contentTitle: "Dunkirk",
  media: {
    name: "dunkirk beach",
    source: {
      url: "http://someurl/image.jpg"
    },
    type: "IMAGE"
  },
  contentText:
    "Men of the British Expeditionary Force (BEF) wade out to a destroyer during the evacuation from Dunkirk."
}

Keyboard Navigation

The timeline can be navigated via keyboard.

• For HORIZONTAL mode use your LEFT RIGHT arrow keys for navigation.
• For VERTICAL or TREE mode, the timeline can be navigated via the UP DOWN arrow keys.
• To easily jump to the first item or the last item in the timeline, use HOME or END keys.

To disable keyboard navigation set disableNavOnKey to true.

<chrono items={items} disableNavOnKey />

Media

Both images and videos can be embedded in the timeline. Just add the media attribute to the Timeline Item model and the component will take care of the rest.

To embed a image

{
  title: "May 1940",
  contentTitle: "Dunkirk",
  media: {
    name: "dunkirk beach",
    source: {
      url: "http://someurl/image.jpg"
    },
    type: "IMAGE"
  }
}

To embed a video

Videos start playing automatically when active and will be automatically paused when not active. Like images, videos are also automatically hidden when not in the visible viewport of the container.

{
  title: "7 December 1941",
  contentTitle: "Pearl Harbor",
  media: {
    source: {
      url: "/pearl-harbor.mp4",
      type: "mp4"
    },
    type: "VIDEO",
    name: "Pearl Harbor"
  }
}

Slideshow mode

Slideshow can be enabled by setting the slideShow prop to true. You can also set an optional slideItemDuration that sets the time delay between cards.

setting this prop enables the play button in the timeline control panel.

<chrono items={items} slideShow slideItemDuration={4500} />

Item Width

The itemWidth prop can be used to set the width of each individual timeline sections. This setting is applicable only for the HORIZONTAL mode.

Theme

Customize colors with theme prop.

<chrono items={items}  titlePosition="BOTTOM" theme={{primary: "red", secondary: "blue" }} />
