Create your Seatchart component:
// Seatchart.tsx
import React, { forwardRef, useEffect, useRef } from 'react';
import SeatchartJS, { Options } from 'seatchart';
interface SeatchartProps {
options: Options;
}
function setForwardedRef<T>(ref: React.ForwardedRef<T>, value: T) {
if (typeof ref === 'function') {
ref(value);
} else if (ref) {
ref.current = value;
}
};
const Seatchart = forwardRef<SeatchartJS | undefined, SeatchartProps>(({ options }, ref) => {
const seatchartRef = useRef<SeatchartJS>();
const elementRef = useRef<HTMLDivElement>(null);
useEffect(() => {
if (elementRef.current && !seatchartRef.current) {
seatchartRef.current = new SeatchartJS(elementRef.current, options);
setForwardedRef(ref, seatchartRef.current);
return () => {
seatchartRef.current = undefined;
setForwardedRef(ref, undefined);
};
}
}, []);
return (
<div ref={elementRef} />
);
});
export default Seatchart;Import it and use it:
// App.tsx
import React, { useRef } from 'react';
import SeatchartJS, { Options } from 'seatchart';
import Seatchart from './Seatchart';
import 'seatchart/dist/seatchart.min.css';
import './App.css';
const options: Options = {
map: {
rows: 7,
columns: 7,
seatTypes: {
default: {
label: 'Economy',
cssClass: 'economy',
price: 10,
},
},
},
};
const App = () => {
const seatchartRef = useRef<SeatchartJS>();
const handleClick = () => {
const index = { row: 0, col: 6 };
const seat = seatchartRef.current?.getSeat(index);
seatchartRef.current?.setSeat(index, {
state: seat?.state === 'selected' ? 'available' : 'selected',
});
};
return (
<div>
<button onClick={handleClick}>Toggle Seat</button>
<Seatchart ref={seatchartRef} options={options} />
</div>
);
}
export default App;And don't forget to style your seats:
/* App.css */
.economy {
color: white;
background-color: #43aa8b;
}
