APIs

ContributionCalendar

ContributionCalendar is the main component of this library. It takes a data property, which is an array of objects representing the contribution data, and a theme property to customize its appearance.

• data: An array of objects, where each object has a date string(YYYY-MM-DD format) as key, and an InputDataProps object as value. Defaults to [].

  • An example data is as follows:

    const data = [
      {
        '2023-07-08': {
          level: 3,
          data: {
            myKey: 'my data',
          },
        },
      },
      {
        '2023-07-09': {
          level: 1,
        },
      },
    ]
    

• theme: Optional. A string that represents a predefined theme name, or an object with custom theme colors. Defaults to grass.

createTheme

createTheme is a helper function to create custom themes. It takes a string representing a predefined theme name or an object containing custom theme colors. This returns a theme object(ThemeProps).

Themes

You can customize the appearance of the <ContributionCalendar /> with the theme property. We provide several built-in themes.

// Replace `theme` attribute with belows 
<ContributionCalendar data={[]} theme={'grass'} />

Custom Theme

import { ContributionCalendar, createTheme } from 'react-contribution-calendar'

function App() {

  /* Define your custom theme */
  const customTheme = createTheme({
    level0: "#ebedf0",
    level1: "#9be9a8",
    level2: "#40c463",
    level3: "#30a14e",
    level4: "#216e39",
  })

  return (
    <ContributionCalendar
      data={[]}
      theme={customTheme}
    />
  )
}

Or you can set theme properties directly,

import { ContributionCalendar } from 'react-contribution-calendar'

function App() {
  return (
    <ContributionCalendar
      data={[]}
      theme={{
        // Assign theme properties directly
        level0: "#ebedf0",
        level1: "#9be9a8",
        level2: "#40c463",
        level3: "#30a14e",
        level4: "#216e39",
      }}
    />
  )
}
