react components which make it simple to create svg arrows in a react app

usage

ArrowSvg

The ArrowSvg component will create a svg component bounding the start and end points you specify and use svg paths to draw the arrow on the svg plane which goes from the "start" position and to the "end" position. The svg is positioned absolutely (position: 'absolute').

example:

is produced by:

  <ArrowSvg start={{ x: 200, y: 300 }} end={{ x: 600, y: 600 }} orientation={LineOrientation.HORIZONTAL} />
  <ArrowSvg start={{ x: 600, y: 300 }} end={{ x: 200, y: 600 }} orientation={LineOrientation.HORIZONTAL} />
  <ArrowSvg start={{ x: 200, y: 600 }} end={{ x: 600, y: 300 }} orientation={LineOrientation.HORIZONTAL} />
  <ArrowSvg start={{ x: 600, y: 600 }} end={{ x: 200, y: 300 }} orientation={LineOrientation.HORIZONTAL} />

Highlighting can be added using the highlight and highlightColor attributes (where highlightColor is any CSS-recognised color name, defaulting to pink if none is specified).

example

is produced by:

  <ArrowSvg start={{ x: 0, y: 0 }} end={{ x: 500, y: 300 }} orientation={LineOrientation.HORIZONTAL} highlight={true} highlightColor="cyan" />

ArrowBetweenDivs

The ArrowBetweenDivs component will keep track of the coordinates of registered divs on the page, so that you can create arrows between them by name (i.e., the id). Tracking the coordinates of the divs on the page is handled by the ArrowsBetweenDivsContextProvider.

example:

is produced by

  import { Bathtub, DriveEta, Work, Hotel, Computer, Kitchen } from '@material-ui/icons';

  // ...

  <ArrowsBetweenDivsContextProvider debug>
    {({ registerDivToArrowsContext }) => (
      <>
        {/* the arrows can be placed anywhere, as they position themselves absolutely and will wait to display until coordinates are registered */}
        <ArrowBetweenDivs
          from={{ id: 'sleep', placement: ArrowAnchorPlacement.TOP }}
          to={{ id: 'code', placement: ArrowAnchorPlacement.BOTTOM }}
          orientation={LineOrientation.VERTICAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'code', placement: ArrowAnchorPlacement.RIGHT }}
          to={{ id: 'shower', placement: ArrowAnchorPlacement.LEFT }}
          orientation={LineOrientation.HORIZONTAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'shower', placement: ArrowAnchorPlacement.RIGHT }}
          to={{ id: 'driveToWork', placement: ArrowAnchorPlacement.LEFT }}
          orientation={LineOrientation.HORIZONTAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'driveToWork', placement: ArrowAnchorPlacement.BOTTOM }}
          to={{ id: 'work', placement: ArrowAnchorPlacement.TOP }}
          orientation={LineOrientation.VERTICAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'work', placement: ArrowAnchorPlacement.LEFT }}
          to={{ id: 'driveFromWork', placement: ArrowAnchorPlacement.RIGHT }}
          orientation={LineOrientation.HORIZONTAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'driveFromWork', placement: ArrowAnchorPlacement.LEFT }}
          to={{ id: 'eat', placement: ArrowAnchorPlacement.RIGHT }}
          orientation={LineOrientation.HORIZONTAL}
        />
        <ArrowBetweenDivs
          from={{ id: 'eat', placement: ArrowAnchorPlacement.LEFT }}
          to={{ id: 'sleep', placement: ArrowAnchorPlacement.RIGHT }}
          orientation={LineOrientation.HORIZONTAL}
        />
