Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Google Map React · npm version Build Status PRs Welcome

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.

See it in action at jsbin

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

...

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.

Thank you

(Really big thanks to April Arcus for documentation fixes)
