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",
cardTitle: "Dunkirk",
cardSubtitle:"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} />
</div>
)
}
Vertical Mode
To render the timeline vertically use the VERTICAL
mode
<div style={{ width: "500px", height: "950px" }}>
<chrono
items={items}
mode="VERTICAL"
/>
</div>
Vertical Alternating
In VERTICAL_ALTERNATING
mode the timeline is rendered vertically with cards alternating between left and right side.
<div style={{ width: "500px", height: "950px" }}>
<chrono
items={items}
mode="VERTICAL_ALTERNATING"

</div>
Slideshow
Play the timeline automatically with the slideShow
mode. This prop enables the play button on the ui controls.

Keyboard Navigation
The timeline can be navigated via keyboard.
- For
HORIZONTAL
mode use your LEFT RIGHT arrow keys for navigation. - For
VERTICAL
orVERTICAL_ALTERNATING
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 />
Scrollable
With the scrollable prop, you can enable scrolling on both VERTICAL
and VERTICAL_ALTERNATING
modes.
<chrono items={items} scrollable />
The scrollbar is not shown by default. To enable the scrollbar, pass an object with prop scrollbar
to scrollable
prop.
<chrono items={items} scrollable={{scrollbar: true}} />
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",
cardTitle: "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",
cardTitle: "Pearl Harbor",
media: {
source: {
url: "/pearl-harbor.mp4",
type: "mp4"
},
type: "VIDEO",
name: "Pearl Harbor"
}
}
To embed YouTube videos, use the right embed url.
{
title: "7 December 1941",
cardTitle: "Pearl Harbor",
media: {
source: {
url: "https://www.youtube.com/embed/f6cz9gtMTeI",
type: "mp4"
},
type: "VIDEO",
name: "Pearl Harbor"
}
}
Rendering custom content
The component also supports embedding custom content in the Timeline
cards.
To insert custom content, just pass the blocked elements between the Chrono
tags.
For e.g the below snippet will create 2 timeline items. Each div
element is automatically converted into a timeline item and inserted into the timeline card.
The items collection is completely optional and custom rendering is supported on all 3 modes.
<Chrono mode="VERTICAL">
<div>
<p>Lorem Ipsum. Lorem Ipsum. Lorem Ipsum</p>
</div>
<div>
<img src="<url to a nice image" />
</div>
</Chrono>
The items collection will also work nicely with any custom content that is passed. The following snippet sets the the title
and cardTitle
for the custom contents.
const items = [
{title: "Timeline title 1", cardTitle: "Card Title 1"},
{title: "Timeline title 2", cardTitle: "Card Title 2"}
];
<Chrono mode="VERTICAL" items={items}>
<div>
<p>Lorem Ipsum. Lorem Ipsum. Lorem Ipsum</p>
</div>
<div>
<img src="<url to a nice image" />
</div>
</Chrono>
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} theme={{primary: "red", secondary: "blue", cardBgColor: "yellow", cardForeColor: "violet" }} />
