Wrap React components with this libary to load the Google Maps JavaScript API.

Google Maps JavaScript API React Wrapper

Description

Wrap React components with this library to load the Google Maps JavaScript API.

import { Wrapper } from "@googlemaps/react-wrapper";

const MyApp = () => (
  <Wrapper apiKey={"YOUR_API_KEY"}>
    <MyMapComponent />
  </Wrapper>
);

The preceding example will not render any elements unless the Google Maps JavaScript API is successfully loaded. To handle error cases and the time until load is complete, it is recommended to provide render props.

import { Wrapper, Status } from "@googlemaps/react-wrapper";

const render = (status) => {
  switch (status) {
    case Status.LOADING:
      return <Spinner />;
    case Status.FAILURE:
      return <ErrorComponent />;
    case Status.SUCCESS:
      return <MyMapComponent />;
  }
};

const MyApp = () => <Wrapper apiKey={"YOUR_API_KEY"} render={render} />;

When combining children and render props, the children will render on success and the render prop will be executed for other status values.

import { Wrapper, Status } from "@googlemaps/react-wrapper";

const render = (status: Status): ReactElement => {
  if (status === Status.FAILURE) return <ErrorComponent />;
  return <Spinner />;
};

const MyApp = () => (
  <Wrapper apiKey={"YOUR_API_KEY"} render={render}>
    <MyMapComponent />
  </Wrapper>
);

@googlemaps/js-api-loader

This wrapper uses @googlemaps/js-api-loader to load the Google Maps JavaScript API. This library uses a singleton pattern and will not attempt to load the library more than once. All options accepted by @googlemaps/js-api-loader are also accepted as props to the wrapper component.

MyMapComponent

The following snippets demonstrates the usage of useRef and useEffect hooks with Google Maps.

function MyMapComponent({
  center,
  zoom,
}: {
  center: google.maps.LatLngLiteral;
  zoom: number;
}) {
  const ref = useRef();

  useEffect(() => {
    new window.google.maps.Map(ref.current, {
      center,
      zoom,
    });
  });

  return <div ref={ref} id="map" />;
}
