If you want the markers to update without a refresh of the page you need to add them to the component state. Since I don't have access to your mongo-db I've used a dummy api just for demo purpose.
And when making api-calls they should be used in Lifecycle-method componentDidMount, not in the constructor.
I've left out the if-statement for local storage and element.userID since I don't know what that is and the component since I don't have access to it.
import React from "react";
import axios from "axios";
export default class Maps extends React.Component {
constructor(props) {
super(props);
this.state = {
dronePosition: []
};
}
componentDidMount() {
this.refreshMarkers();
}
refreshMarkers = () => {
// Clear state to prevent duplicates
this.setState({dronePosition: []});
const config = {
headers: {
Authorization: `Bearer ${localStorage.getItem("token")}`
}
};
axios.get("https://swapi.co/api/starships").then(res => {
res.data.results.forEach(element => {
this.setState({
dronePosition: [...this.state.dronePosition, element]
});
});
console.log(this.state.dronePosition);
});
};
render() {
return(
<div>
<div onClick={this.refreshMarkers}>Click on me to refresh markersdiv>
render the map here...
div>
);
}

I want to move multiple markers on the google map when I get the latitude and longitude from MongoDB. I'm always getting updated latitude and longitude from db, but my markers are not moving, and after refreshing the page, the markers positions are changing, but I need to do it without refreshing the page.
This is my code`
