React-Leaflet draw circle markers on map - reactjs

Question

I'm new to Leaflet/React-Leaflet and I am trying to plot a circle marker on a map and I'm having trouble. React-Leaflet's documentation is not very good. I have figured out how to add a popup that shows on click though.
Here's my code:
import React from 'react';
import { render } from 'react-dom';
import { Map, Marker, Popup, TileLayer, Tooltip, Circle } from 'react-leaflet';
import DivIcon from 'react-leaflet-div-icon';
import axios from 'axios';
export default class MapView extends React.Component {
constructor(props) {
super(props)
this.state = {
nasaLocations: [],
spacexLocations: []
};
}
componentDidMount() {
axios.get(`https://data.nasa.gov/resource/gvk9-iz74.json`)
.then(res => {
const nasaData = res.data;
this.setState({nasaLocations: nasaData})
console.log(this.state.nasaLocations);
})
axios.get(`https://api.spacexdata.com/v2/launchpads`)
.then(res => {
const spacexData = res.data;
this.setState({spacexLocations: spacexData})
console.log(this.state.spacexLocations);
})
}
render() {
const position = [40.730610, -73.935242];
return (
<Map
style={{height: "100vh"}}
center={position}
zoom={3}>
<TileLayer
url="https://api.mapbox.com/styles/v1/nicknyr/cje7mtk2y6gf92snsydobiahf/tiles/256/{z}/{x}/{y}?access_token=pk.eyJ1Ijoibmlja255ciIsImEiOiJjajduNGptZWQxZml2MndvNjk4eGtwbDRkIn0.L0aWwfHlFJVGa-WOj7EHaA"
attribution="<attribution>" />
<Marker position={position}>
<Popup>
<span>
A pretty CSS3 popup. <br /> Easily customizable.
</span>
</Popup>
</Marker>
</Map>
);
}
}
How can I render a circle on those position coordinates? I've attemped to add a type tag within the Map tag but I can't figure out the proper syntax and how to properly add lat/long coordinates.

Answer 1

I have little experience with Leaflet, but I got a circle to render, here is the example. I passed the latlng coords using an obj. Hope this helps. If this didn't answer the question, let me know. Circles show up on each location, with the pop-up showing the details from the space x api.
import React, { Component } from 'react';
import { Map, TileLayer, Marker, Tooltip,Popup, Circle} from 'react-leaflet';
import axios from 'axios';
const url = 'https://api.spacexdata.com/v2/launchpads';
const leafURL = "https://api.mapbox.com/styles/v1/nicknyr/cje7mtk2y6gf92snsydobiahf/tiles/256/{z}/{x}/{y}?access_token=pk.eyJ1Ijoibmlja255ciIsImEiOiJjajduNGptZWQxZml2MndvNjk4eGtwbDRkIn0.L0aWwfHlFJVGa-WOj7EHaA";
class App extends Component {
constructor(props){
super(props);
this.state = {
latlng: {
lat: 28.5618571,
lng: -80.577366,
},
data: []
}
}
componentWillMount() {
axios.get(url).then(res => {
this.setState({data: res.data})
}).catch(err => {
console.log('error')
})
}
render() {
const {data} = this.state;
console.log(data);
return (
<div>
<Map
style={{height: "100vh"}}
center={this.state.latlng}
zoom={4}>
<TileLayer
url={leafURL}
attribution="<attribution>" />
{data.map((elem, i) => {
return (
<Marker
key={i}
position={{lat:elem.location.latitude, lng: elem.location.longitude}}>
<Popup>
<span>
{elem.full_name}<br />
{elem.status}<br />
{elem.details}<br />
{elem.vehicles_launched.map((elem, i) => {
return ( <p key={i}>{elem}</p>)
})}
</span>
</Popup>
<Circle
center={{lat:elem.location.latitude, lng: elem.location.longitude}}
fillColor="blue"
radius={200}/>
</Marker>
)
})}
</Map>
</div>
);
}
}
export default App;
