⚡️ React Headless Timeline

Headless components for building custom timelines for React. Headless means it doesn't provide any UI or styles for the timeline but only handles the logic. Supports both horizontal and vertical timelines.

🚀 Test, build and publish

React Headless Timeline

Features ✨


  • ⚡️ Highly performant and efficient
  • 🔒 Type safe - written in TypeScript
  • 🫧 Doesn't render any UI nor styles - it's totally up to you how you're going to style your timeline
  • 🧩 Supports horizontal and vertical timelines
  • 🏃‍ Small bundle size

Overview 👓


See what this library does and doesn't for you and decide whether it's a good fit for you or not.

👍 What it does for you:

  • It handles the timeline logic
  • It helps you render timeline components in correct position and size

👎 What it doesn't for you:

  • It doesn't provide any pre-styled UI components for you (no need to overwrite styles to make timeline looks like in designer's dream)

npm install react-headless-timeline

Quick start 👨‍💻


import Timeline from 'react-headless-timeline';

function App() {
  const timelineConfig = {
    startDate: new Date(1651201447127), // 29th Apr 2022 05:04:07 CET
    endDate: new Date(1651221447127), // 29th Apr 2022 10:37:27 CET
  }

  const events = [
    { 
      startDate: new Date(1651204649127), // 29th Apr 2022 05:57:29 CET
      endDate: new Date(1651214649127), // 29th Apr 2022 08:44:09 CET
    },
  ];
  
  return (
    <Timeline.Provider {...timelineConfig}>
      <>
        <Timeline.Headers
          render={({ headers, getHeaderStyles }) => (
            <div style={{ position: 'relative', width: '100%', height: 30 }}>
              {headers.map((header) => (
                <span key={header.getTime()} style={getHeaderStyles(header)}>
                  {header.getTime()}
                </span>
              ))}
            </div>
          )}
        />

        <Timeline.Events
          render={({ getEventStyles }) => (
            <div style={{ position: 'relative', width: '100%', height: 30 }}>
              {events.map((evt, i) => (
                <span key={i} style={getEventStyles(evt)}>
                  Event
                </span>
              ))}
            </div>

        />
      </>
    </Timeline.Provider>
  );

API 📚


  • Timeline.Provider

    Core timeline component. You have to wrap all of your timeline components inside provider.

    Props: (* - these are required)

    Name Type Default Description
    startDate * Date
    endDate * Date
    direction "horizontal" / "vertical" "horizontal" Determines timeline direction

    Example:

    import Timeline from 'react-headless-timeline';
    
    // ...
    
    <Timeline.Provider startDate={startDate} endDate={endDate} direction="horizontal">
      {children}
    </Timeline.Provider>

    Other examples: See all ⬇️


  • Timeline.Headers

    Provides headers and helper function to generate headers CSS styles (size and position).

    Props: (* - these are required)

    Name Type Default Description
    cells number 2 Determines how many headers/cells you want to render. For example if you have a timeline with startDate set to today 10AM and endDate set to today 4PM, by default headers will be an array with startDate and endDate. But let's say you want to display headers every 1 hour, you should then set cells to 7 - [10AM, 11AM, 12AM, 1PM, 2PM, 3PM, 4PM]. The minimum value is 2
    render * function Render your UI inside this function. See example below...

    Example:

    import Timeline from 'react-headless-timeline';
    
    // ...
    
    <Timeline.Headers
      render={({ headers, getHeaderStyles }) => (
        <div>
          {headers.map((header) => (
            <span key={header.getTime()} style={getHeaderStyles(header)}>
              {header.getTime()}
            </span>
          ))}
        </div>
      )}
    />

  • Timeline.Events

    Provides helper function to generate event CSS styles (size and position).

    Props: (* - these are required)

    Name Type Default Description
    render * function Render your UI inside this function. See example below...

    Example:

    import Timeline from 'react-headless-timeline';
    
    // ...
    
    <Timeline.Events
      render={({ getEventStyles }) => (
        <div>
          {events.map((evt, i) => (
            <span key={i} style={getEventStyles(evt)}>
              Event
            </span>
          ))}
        </div>
      )}
    />

  • Timeline.Indicators.CurrentTime

    Provides current time indicator with updates (re-renders) every second or full minute. This component will re-render itself.

    Update every full minute means update at 10:45:00, 10:46:00 and so on...

    Props: (* - these are required)

    Name Type Default Description
    updateInterval "second" / "minute" "minute" Determines update interval. In most cases you'll want to use "minute" option to limit re-renders
    render * function Render your UI inside this function. See example below...

    Example:

    import Timeline from 'react-headless-timeline';
    
    // ...
    
    <Timeline.Indicators.CurrentTime
      render={({ currentTime, styles }) => (
        <div style={{ height: '100%', ...styles }}>
          <StyledHeader>{currentTime.getTime()}</StyledHeader>
        </div>
      )}
    />

    Other examples:

  • Timeline.Indicators.Time

    This indicator exposes function to position your component properly. It's useful for events without end date.

    Props: (* - these are required)

    Name Type Default Description
    render * function Render your UI inside this function. See example below...

    Example:

    import Timeline from 'react-headless-timeline';
    
    // ...
    
    <Timeline.Indicators.Time
      render={({ getIndicatorStyles }) => (
        <div style={{ height: '100%', ...getIndicatorStyles(date) }}>
          <StyledHeader>
            {label}
          </StyledHeader>
        </div>
      )}
    />

General rules 📝


  • You should use CSS box-sizing: border-box on your timeline components to prevent sizing bugs.

Roadmap 🗺


  • Create detailed documentation
  • Add more advanced examples of usage of react-headless-timeline
  • (?) Add support for overflow timelines
  • (?) Add possibility to create virtualized timelines
