- Screenshot Of double elimination bracket out of the box
I was scouring the world wide web for a good component library for visualizing single elimination brackets or double elimination brackets but most of them had complicated data structures or didn't allow for easy styling, and so I had to build my own, and decided to share it with the world.
You only need to have react installed in your project to use this project.
Note: default browser css is reset using the minireset.css package in the storybook demos. To fully control what the match component looks like you can build and supply your own view component for it
This project is hosted on the public npm registry, here's the link to the npm page
npm install @g-loot/react-tournament-bracketsimport { SingleEliminationBracket, DoubleEliminationBracket, Match, MATCH_STATES, SVGViewer } from '@g-loot/react-tournament-brackets';
| Component | Description |
|---|---|
| SingleEliminationBracket | Component for displaying single elimination bracket |
| DoubleEliminationBracket | Component for displaying double elimination bracket |
| Match | Default component for rendering matches that can be overridden |
| MATCH_STATES | Constant containing enum for Match states and Participants statuses |
| SVGViewer | Optional component for displaying the bracket in a fixed size window with panning and zooming functionality |
This component generates an SVG of all your bracket matches, you can use the supplied optional component <SVGViewer /> like in the following example to wrap the SVG in a fixed size window with panning and zooming functionality, Note that you're also free to come up with your own solution for allowing the user to navigate giant brackets with ease.
import { SingleEliminationBracket, DoubleEliminationBracket, Match, SVGViewer } from '@g-loot/react-tournament-brackets';
export const DoubleElimination = () => (
<DoubleEliminationBracket
matches={matches}
matchComponent={Match}
svgWrapper={({ children, ...props }) => (
<SVGViewer width={500} height={500} {...props}>
{children}
</SVGViewer>
)}
/>
);
export const SingleElimination = () => (
<SingleEliminationBracket
matches={matches}
matchComponent={Match}
svgWrapper={({ children, ...props }) => (
<SVGViewer width={500} height={500} {...props}>
{children}
</SVGViewer>
)}
/>
);- If you want the
SVGViewerto fit it's container you will need some sort of hook to achieve that, like useWindowSize(), useComponentSize or your own custom solution
import { DoubleEliminationBracket, Match, SVGViewer } from '@g-loot/react-tournament-brackets';
export const DoubleElimination = () => {
const [width, height] = useWindowSize();
const finalWidth = Math.max(width - 50, 500);
const finalHeight = Math.max(height - 100, 500);
return (
<DoubleEliminationBracket
matches={matches}
matchComponent={Match}
svgWrapper={({ children, ...props }) => (
<SVGViewer width={finalWidth} height={finalHeight} {...props}>
{children}
</SVGViewer>
)}
/>
);

matchesprop structure with double finals, Keep the same structure and add a nextMatchId + nextLooserMatchId pointing to a new match in the same bracket (the finals can be in upper or in lower bracket) _For more examples of valid double finals data, check out the mock data folder specifically data-double-last-game-lower.ts and data-double-last-game-upper-double-playoffs.ts _

This component's default theme is the dark theme in the screenshot, you can use the function createTheme which is exported from the library to create a theme and then pass it to either single or double bracket on the theme prop
A few notes:
- Some colors like the roundHeaders, and connectors aren't tied to the theme yet, you'll need to style those through the
optionsprop manually for now, In the very near future they will be tied to the theme as well!
import { SingleEliminationBracket, Match, SVGViewer, createTheme } from '@g-loot/react-tournament-brackets';
const WhiteTheme = createTheme({
textColor: { main: '#000000', highlighted: '#07090D', dark: '#3E414D' },
matchBackground: { wonColor: '#daebf9', lostColor: '#96c6da' },
score: {
background: { wonColor: '#87b2c4', lostColor: '#87b2c4' },
text: { highlightedWonColor: '#7BF59D', highlightedLostColor: '#FB7E94' },
},
border: {
color: '#CED1F2',
highlightedColor: '#da96c6',
},
roundHeader: { backgroundColor: '#da96c6', fontColor: '#000' },
connectorColor: '#CED1F2',
connectorColorHighlight: '#da96c6',
svgBackground: '#FAFAFA',
});
export const WhiteThemeBracket = () => {
const [width, height] = useWindowSize();
const finalWidth = Math.max(width - 50, 500);
const finalHeight = Math.max(height - 100, 500);
return (
<SingleEliminationBracket
matches={simpleSmallBracket}
matchComponent={Match}
theme={WhiteTheme}
options={{
style: {
roundHeader: {
backgroundColor: WhiteTheme.roundHeader.backgroundColor,
fontColor: WhiteTheme.roundHeader.fontColor,
},
connectorColor: WhiteTheme.connectorColor,
connectorColorHighlight: WhiteTheme.connectorColorHighlight,
},
}}
svgWrapper={({ children, ...props }) => (
<SvgViewer
background={WhiteTheme.svgBackground}
SVGBackground={WhiteTheme.svgBackground}
width={finalWidth}
height={finalHeight}
{...props}
>
{children}
</SvgViewer>
)}
/>
);
};If themes aren't enough for you you can always supply your own Match view component and use the props passed to it to override the match view rendering, Again you'll need to style the round headers and connector lines using options prop
import { SingleEliminationBracket, SVGViewer } from '@g-loot/react-tournament-brackets';
export const CustomMatchBracket = () => {
const [width, height] = useWindowSize();
const finalWidth = Math.max(width - 50, 500);
const finalHeight = Math.max(height - 100, 500);
return (
<SingleEliminationBracket
matches={simpleSmallBracket}
options={{
style: {
roundHeader: { backgroundColor: '#AAA' },
connectorColor: '#FF8C00',
connectorColorHighlight: '#000',
},
}}
svgWrapper={({ children, ...props }) => (
<SvgViewer
background="#FFF"
SVGBackground="#FFF"
width={finalWidth}
height={finalHeight}
{...props}
>
{children}
</SvgViewer>
)}
matchComponent={({
match,
onMatchClick,
onPartyClick,
onMouseEnter,
onMouseLeave,
topParty,
bottomParty,
topWon,
bottomWon,
topHovered,
bottomHovered,
topText,
bottomText,
connectorColor,
computedStyles,
teamNameFallback,
resultFallback,
}) => (
<div
style={{
display: 'flex',
flexDirection: 'column',
justifyContent: 'space-around',
color: '#000',
width: '100%',
height: '100%',
}}
>
<div
onMouseEnter={() => onMouseEnter(topParty.id)}
style={{ display: 'flex' }}
>
<div>{topParty.name || teamNameFallback}</div>
<div>{topParty.resultText ?? resultFallback(topParty)}</div>
</div>
<div
style={{ height: '1px', width: '100%', background: '#FF8C00' }}
/>
<div
onMouseEnter={() => onMouseEnter(bottomParty.id)}
style={{ display: 'flex' }}
>
<div>{bottomParty.name || teamNameFallback}</div>
<div>{bottomParty.resultText ?? resultFallback(topParty)}</div>
</div>
</div>
)}
/>
);
