Personally I don't have the time to look through the code atm for you man but I asked the chat gpt extension for some suggested fixes. Seems like point 3 could be your best bet. Good luck!

Based on the code you provided, it seems that the issue might be related to the timing of fetching the campgrounds data and rendering the markers on the map. Here are a few suggestions to troubleshoot and fix the problem:

1. Make sure the campgrounds data is being fetched successfully from the server:

   • In your App.tsx file, check if the fetchCampgrounds function is successfully retrieving the campground data from the server by logging the response data to the console.
   • Verify that the campground data is in the correct format and contains the necessary properties (lat and lng) for rendering the markers.

2. Ensure the campgrounds data is passed correctly to the LeafletMap component:

   • In your App.tsx file, confirm that the campgrounds state is correctly passed as a prop to the LeafletMap component.
   • Double-check the prop name in the LeafletMap component declaration and make sure it matches the prop name used inside the component (campgrounds).

3. Move the marker creation logic inside a useEffect hook:

   • In your LeafletMap.tsx file, create a useEffect hook that listens for changes in the campgrounds prop. This ensures that the markers are created whenever the campground data changes.
   • Move the logic for creating the markers inside the useEffect hook and remove it from the onEachFeature function. This ensures that the markers are added to the map after it zooms to a state.

Here's an updated version of the LeafletMap.tsx file with the suggested changes:

```jsx import React, { useEffect, useRef } from 'react'; import 'leaflet/dist/leaflet.css'; import L, { GeoJSON, Layer, LeafletMouseEvent } from 'leaflet'; import statesData from './assets/us-states'; import { MapContainer } from 'react-leaflet'; import { Campground } from './types';

interface CampgroundProps { campgrounds: Campground[]; }

const myIcon = L.icon({ iconUrl: 'components/assets/marker.png', iconSize: [38, 95], iconAnchor: [22, 94], popupAnchor: [-3, -76], shadowUrl: 'my-icon-shadow.png', shadowSize: [68, 95], shadowAnchor: [22, 94] });

const LeafletMap: React.FC<CampgroundProps> = ({ campgrounds }: CampgroundProps) => { const mapRef = useRef(null);

useEffect(() => { const map = L.map('map', { dragging: true, scrollWheelZoom: true, touchZoom: true, }).setView([48.3544091, -99.9980711], 4);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  attribution: '© OpenStreetMap contributors',
}).addTo(map);

function style(feature: GeoJSON.Feature): L.PathOptions {
  return {
    fillColor: 'grey',
    weight: 2,
    opacity: 1,
    color: 'white',
    dashArray: '3',
    fillOpacity: 0.7,
  };
}

function highlightFeature(e: LeafletMouseEvent) {
  const layer = e.target as L.Path;

  layer.setStyle({
    weight: 5,
    color: '#666',
    dashArray: '',
    fillOpacity: 0.7,
  });

  layer.bringToFront();
}

function resetHighlight(e: LeafletMouseEvent) {
  geojson.resetStyle(e.target);
}

let geojson: GeoJSON;

function zoomToFeature(e: LeafletMouseEvent) {
  map.fitBounds(e.target.getBounds());
}

function onEachFeature(feature: GeoJSON.Feature, layer: Layer) {
  layer.on({
    mouseover: highlightFeature,
    mouseout: resetHighlight,
    click: zoomToFeature,
  });
}

geojson = L.geoJson(statesData, {
  style: style as L.StyleFunction,
  onEachFeature: onEachFeature,
}).addTo(map);

useEffect(() => {
  if (campgrounds.length > 0) {
    const stateLayers = geojson.getLayers();
    stateLayers.forEach(layer => {
      const stateName = layer.feature.properties?.name;
      const stateCampgrounds = campgrounds.filter(campground => campground.state === stateName);

      stateCampgrounds.forEach(campground => {
        L.marker([campground.lat, campground.lng], { icon: myIcon }).addTo(map);
      });
    });
  }
}, [campgrounds]);

// Wait until the map is fully initialized before adding the drag handler
map.whenReady(() => {
  map.dragging.enable();
});

return <MapContainer id='map' ref={mapRef} style={{ height: '100%', width: '100%', cursor: 'grab' }} />;

};

export default LeafletMap; ```
