Google Maps and React With a Custom Marker

google-map-react is a component written over a small set of the Google Maps API. It allows you to render any React component on the Google Map. It is fully isomorphic and can render on a server. Additionally, it can render map components in the browser even if the Google Maps API is not loaded. It uses an internal, tweakable hover algorithm - every object on the map can be hovered.

It allows you to create interfaces like this example (You can scroll the table, zoom/move the map, hover/click on markers, and click on table rows)

Getting started

In the simple case you just need to add lat and lng props to any child of GoogleMapReact component.

source-js
import React, { Component } from 'react';
import GoogleMapReact from 'google-map-react';

const AnyReactComponent = ({ text }) => <div>{text}</div>;

class SimpleMap extends Component {
  static defaultProps = {
    center: {
      lat: 59.95,
      lng: 30.33
    },
    zoom: 11
  };

  render() {
    return (
      // Important! Always set the container height explicitly
      <div style={{ height: '100vh', width: '100%' }}>
        <GoogleMapReact
          bootstrapURLKeys={{ key: /* YOUR KEY HERE */ }}
          defaultCenter={this.props.center}
          defaultZoom={this.props.zoom}
        >
          <AnyReactComponent
            lat={59.955413}
            lng={30.337844}
            text="My Marker"
          />
        </GoogleMapReact>
      </div>
    );
  }
}

export default SimpleMap;

My map doesn’t appear!

• Make sure the container element has width and height. The map will try to fill the parent container, but if the container has no size, the map will collapse to 0 width / height. This is not a requirement for google-map-react, its a requirement for google-maps in general.

Installation

npm:

npm install --save google-map-react

yarn:

yarn add google-map-react

Features

Works with your Components

Instead of the ugly Google Maps markers, balloons and other map components, you can render your cool animated react components on the map.

Isomorphic Rendering

It renders on the server. (Welcome search engines) (you can disable javascript in browser dev tools, and reload any example page to see how it works)

Component Positions Calculated Independently of Google Maps API

It renders components on the map before (and even without) the Google Maps API loaded.

Google Maps API Loads on Demand

There is no need to place a <script src= tag at top of page. The Google Maps API loads upon the first usage of the GoogleMapReact component.

Use Google Maps API

You can access to Google Maps map and maps objects by using onGoogleApiLoaded, in this case you will need to set yesIWantToUseGoogleMapApiInternals to true

source-js
...

const handleApiLoaded = (map, maps) => {
  // use map and maps objects
};

...

<GoogleMapReact
  bootstrapURLKeys={{ key: /* YOUR KEY HERE */ }}
  defaultCenter={this.props.center}
  defaultZoom={this.props.zoom}
  yesIWantToUseGoogleMapApiInternals
  onGoogleApiLoaded={({ map, maps }) => handleApiLoaded(map, maps)}
>
  <AnyReactComponent
    lat={59.955413}
    lng={30.337844}
    text="My Marker"
  />
</GoogleMapReact>

PST: Remember to set yesIWantToUseGoogleMapApiInternals to true.

Example here

Internal Hover Algorithm

Now every object on the map can be hovered (however, you can still use css hover selectors if you want). If you try zooming out here example, you will still be able to hover on almost every map marker.

Examples

• Placing react components on the map: simple (source)

• Custom map options: example (source)

• Hover effects: simple hover (source); distance hover (source)

• GoogleMap events: example (source)

• Example project: main (source); balderdash (same source as main)

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How to make a marker draggable?

To allow users to drag a marker to a different location on the map, set the draggable attribute to true in the marker options.

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
  zoom: 4,
  center: myLatlng
}
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
// Place a draggable marker on the map
var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    draggable:true,
    title:"Drag me!"
});
