react-usa-map | A simple SVG USA map rendering on React

This is an alternate version for you that just want a simple customizable map on HTML. This maps shows states delimitations including DC, Alaska, and Hawaii. D3 is not needed.

It uses the Albers projection.

Live Example

Live: http://react-usa-map-demo.herokuapp.com

Code: http://github.com/gabidavila/react-usa-map-demo

Installation

It requires react 16.13.1 or higher. Run:

yarn add react-usa-map

or

npm install react-usa-map --save

Usage

The below example shows the mandatory onClick event.

import React, { Component } from 'react';
import USAMap from "react-usa-map";

class App extends Component {
  /* mandatory */
  mapHandler = (event) => {
    alert(event.target.dataset.name);
  };

  render() {
    return (
      <div className="App">
        <USAMap onClick={this.mapHandler} />
      </div>
    );
  }
}

export default App;

Example with optional props, App.js:

import React, { Component } from 'react';
import './App.css'; /* optional for styling like the :hover pseudo-class */
import USAMap from "react-usa-map";

class App extends Component {
  /* mandatory */
  mapHandler = (event) => {
    alert(event.target.dataset.name);
  };

  /* optional customization of filling per state and calling custom callbacks per state */
  statesCustomConfig = () => {
    return {
      "NJ": {
        fill: "navy",
        clickHandler: (event) => console.log('Custom handler for NJ', event.target.dataset)
      },
      "NY": {
        fill: "#CC0000"
      }
    };
  };

  render() {
    return (
      <div className="App">
        <USAMap customize={this.statesCustomConfig()} onClick={this.mapHandler} />
      </div>
    );
  }
}

export default App;

App.css:

path {
  pointer-events: all;
}
path:hover {
  opacity: 0.50;
  cursor: pointer;
}

All optional props:

prop	description
title	Content for the Title attribute on the svg
width	The width for rendering, numeric, no px suffix
height	The height for rendering, numeric, no px suffix
defaultFill	The default color for filling
customize	Optional customization of filling per state

Additionally each path tag has an abbreviation of the current state followed by a state class:

<path fill="#{custom color or #D3D3D3}" data-name="CA" class="CA state" d="...{polygon dimensions here}..."></path>
