Adding a map component to my app using react leaflet. The map displays fine, along with geoJSONs. Popups will go where I want them but are invisible.

The biggest issue is that the zoom controls (+- buttons) that I see in every online example have not been displaying. Map Component

Here is the code for it:

import React, { PureComponent, Component} from 'react'
import './Map.css'
import 'leaflet/dist/leaflet.css'
import { MapContainer, TileLayer, Marker, GeoJSON, ZoomControl, Popup} from 'react-leaflet'


class MapView extends PureComponent {
  constructor(props) {
    super(props);
  }
  render () {
    var position = [40.8, -74.15]

return (
  
    <MapContainer
      className='Map-Container'
      center={position}
      zoom={14}
      minZoom={10}
      maxZoom={16}
    >
      <ZoomControl position="topleft" />
      <Marker position={position}>
        <Popup>
          A pretty CSS3 popup. <br /> Easily customizable.
        </Popup>
      </Marker>
      <TileLayer
        className='TileLayer'
        url='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}'

      />
    </MapContainer>
)

} }

export default MapView
