  • Custom Icons: Use your own icons to represent timeline points for a unique look.
  • TypeScript Support: Benefit from type safety and improved developer experience with built-in TypeScript definitions.

Installation

To get started with React Chrono, you’ll need to install it in your React project. You can do this using npm or yarn:

npm install react-chrono
# or
yarn add react-chrono

Basic Usage

Let’s explore how to create a simple timeline using React Chrono:

Importing the Component

First, import the Chrono component and its styles in your React file:

import { Chrono } from "react-chrono";
import "react-chrono/dist/styles.css";

Creating Timeline Items

Next, define an array of items that will populate your timeline:

const items = [
  {
    title: "May 1940",
    cardTitle: "Dunkirk",
    cardSubtitle: "Men of the British Expeditionary Force (BEF) wade out to...",
    cardDetailedText: "On 10 May 1940, Hitler began his long-awaited offensive in the west...",
    media: {
      type: "IMAGE",
      source: {
        url: "http://someurl/image.jpg"
      }
    }
  },
  // Add more items as needed
];

Each item in the array represents a point on the timeline. You can include various properties such as title, subtitle, detailed text, and media to create rich content for each event.

Rendering the Timeline

Now, you can render the Chrono component with your items:

const TimelineComponent = () => {
  return (
    <div style={{ width: "500px", height: "400px" }}>
      <Chrono items={items} mode="VERTICAL" />
    </div>
  );
};

This basic setup will create a vertical timeline with the items you’ve defined. The mode prop determines the layout of the timeline, which can be “VERTICAL”, “HORIZONTAL”, or “VERTICAL_ALTERNATING”.

Advanced Usage

React Chrono offers several advanced features that allow for more complex and customized timelines:

Custom Content Rendering

You can render custom content within timeline cards by passing React elements as children to the Chrono component:

<Chrono mode="VERTICAL">
  <div>
    <h3>Custom Event Title</h3>
    <p>This is a custom event description with rich content.</p>
    <img src="/custom-image.jpg" alt="Custom event" />
  </div>
  {/* Add more custom elements */}
</Chrono>

This approach gives you full control over the content and styling of each timeline item.

Nested Timelines

Create hierarchical timelines by including a nested items array within a timeline item:

const items = [
  {
    title: "Parent Event",
    cardTitle: "Main Milestone",
    items: [
      {
        title: "Sub-event 1",
        cardTitle: "Nested Milestone 1"
      },
      {
        title: "Sub-event 2",
        cardTitle: "Nested Milestone 2"
      }
    ]
  }
];

Nested timelines are particularly useful for representing complex historical events or project structures with multiple levels of detail.

Slideshow Mode

Enable automatic progression through timeline events with the slideshow mode:

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

This feature is great for creating engaging presentations or displays where you want the timeline to progress automatically.

Custom Timeline Point Icons

Personalize your timeline points with custom icons:

<Chrono items={items}>
  <div className="chrono-icons">
    <img src="/icon1.png" alt="Custom icon 1" />
    <img src="/icon2.png" alt="Custom icon 2" />
    {/* Add more icons as needed */}
  </div>
</Chrono>

Custom icons can help to visually distinguish different types of events or add branding elements to your timeline.

Theme Customization

React Chrono allows for extensive theme customization to match your application’s design:

const customTheme = {
  primary: "#ffd700",
  secondary: "#ff4500",
  cardBgColor: "#f5f5f5",
  cardForeColor: "#333",
  titleColor: "#000",
  titleColorActive: "#0000ff"
};

<Chrono items={items} theme={customTheme} />

By defining a custom theme object, you can control various color aspects of the timeline, ensuring it integrates seamlessly with your application’s aesthetic.

Media Integration

Enhance your timeline with rich media content:

const items = [
  {
    title: "Video Event",
    cardTitle: "Embedded Video",
    media: {
      type: "VIDEO",
      source: {
        url: "https://www.youtube.com/embed/dQw4w9WgXcQ"
      }
    }
  },
  {
    title: "Image Event",
    cardTitle: "High-Resolution Image",
    media: {
      type: "IMAGE",
      source: {
        url: "https://example.com/high-res-image.jpg"
      }
    }
  }
];

By including media in your timeline items, you can create more immersive and informative timeline experiences.

Keyboard Navigation

React Chrono comes with built-in keyboard navigation, enhancing accessibility:

<Chrono items={items} enableOutline />

The enableOutline prop ensures that keyboard focus is visible, making it easier for users to navigate the timeline using keyboard controls.
