Next js with react-leaflet window is not defined when refreshing page


im using react-leaflet in Next js but when reloading page shows "window is not defined" even i am using dynamic import with ssr:false, i saw this question made by others here and tried answers that they offered but didn't work, also tried to make the map mounted after component but again no result, my code:

function ContactPage() {
    const MapWithNoSSR = dynamic(() => import('../Map/Map'), {
        ssr: false,
    })
    return (
        <div className={styles.map}>
            <MapWithNoSSR/>
        </div>
    )
}

function Map(){

const [markers, setMarkers]= useState([
        {cord:[12.3774729,20.446257]},
        {cord:[45.3774729,10.45224757]},
        {cord:[40.3774729,15.4364757]},
    ])

<MapContainer center={[12.374729,22.4464757]} zoom={13} scrollWheelZoom={true} style={{height: "100%", width: "100%",zIndex:'1'}}>
          <TileLayer
              url={`example.com`}
              attribution='Map data &copy; <a>Mapbox</a>'
          />
          {markers?.map((element,idx)=>{
            return <Marker
                position={element?.cord}
                draggable={true}
                animate={true}
                key={idx}
            >
              <Popup>
                Test PopUP
              </Popup>
            </Marker>
          })}
        </MapContainer> 

}}
}

Solution

  • as you were told in the comment, dynamic () has to go outside of the component or screen you are going to return, e. g.

    import dynamic from "next/dynamic"
    
    const MyAwesomeMap = dynamic(() => import("../components/Map/index"), { ssr:false })
    
    export default function inicio() {
    
    return(
     <>
      <p>Example Map</p>
      <MyAwesomeMap />
     </>
     )
    }
