I am struggling over the way to use Google Map API inside a React component. I did not want to use popular react-google-maps nor google-map-react packages, but rather create my own.
I managed to load the script tag with the Google Map API from the React component. However, how do I manipulate the Google API from here? For example, initializing the map with even basic configuration like below?
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8
});
Here is my component. Any advice is appreciated! thanks!
import React, { Component } from 'react';
// Load Google API in script tag and append
function loadScript(src) {
return new Promise((resolve, reject) => {
let script = document.createElement('script');
script.src = src;
script.addEventListener('load', function() {
resolve();
});
script.addEventListener('error', function(e) {
reject(e);
});
document.body.appendChild(script);
});
}
const script = 'https://maps.googleapis.com/maps/api/js?key=MY_API_KEY';
class MyGoogleMap extends Component {
constructor(props) {
super(props);
this.state = {};
}
componentDidMount() {
// first load the script into html
loadScript(script).then(function() {
console.log('SUCCESS');
// Where do I go from here?
});
}
render() {
return <div />;
}
}
export default MyGoogleMap;Answer
I actually found my own solution, so I am sharing for anyone who would meet the same problem.
The basic logic is to use window object to access google.
So, after I load the script as I did from the question, I initialize my map as:
initMap = () => {
// 'google' could be accessed from 'window' object
const map = new window.google.maps.Map(
document.getElementById('googleMap'),
{
zoom: 14,
center: { lat: LATITUDE, lng: LONGTITUDE }
}
);
// putting a marker on it
const marker = new window.google.maps.Marker({
position: { lat: LATITUDE, lng: LONGTITUDE },
map: map
});
};
render() {
return (
<div id="googleMap" style={width: WIDTH, height: HEIGHT}/>
);
}Any comment is welcomed 🙂
