    </div>
  );
}

See examples folder for more example.

Getting started

Read carefully the getting started section of Mapbox GL API.

If you use Webpack, you should add the following parameter in order to properly build your app.

module: {
    noParse: /(mapbox-gl)\.js$/,
}

react-mapbox-wrapper import the corresponding CSS stylesheet from Javascript, you don’t have to do it.

API

MapboxMap

React Component that render a Mapbox Map. Extra props are directly passed to the Map constructor. Following props are handled by wrapper for updating or handling behavior in the React philosophy.

Wrapper is CSS flex-ready for width but you have to set a height for having visible Mapbox.

Props	Type	Default	Description
accessToken	String	required	Mapbox Access Token (find it here)
coordinates	Object	required	Coordinates of the map center
According to the LngLatLike model
className	string	''	className added to map’s wrapper. Your should provide a height in order to render the map (default at 0)
children	Node	null	Rendered children, typically a Marker and/or Circle
minZoom	number	undefined	The minimum zoom level of the map (0-24).
maxZoom	number	undefined	The maximum zoom level of the map (0-24).
zoom	number	15	The viewport zoom
onChange	func	undefined	Callback function called on every viewport change (moveend, zoomend)

Callback receive param with the following shape
{ zoom: 15, coordinates: { lng: 3.4, lat: 1.2 } } |
| onClick | func | undefined | Callback function called on map’s click |
| onLoad | func | undefined | Callback function called on map’s load with current Mapbox instance param |
| onZoomStart | func | undefined | Callback function called on map’s zoomstart |
| onZoomEnd | func | undefined | Callback function called on map’s zoomend with a debounce of 300ms in order to avoid too many render() call |
| renderNotSupported | func | Simple message | Callback function called when browser does not support mapbox-gl |
| mapboxStyle | String | | Mapbox style layer |
| withCompass | bool | false | Show compass Navigation Control |
| withFullscreen | bool | false | Show Fullscreen Control |
| withZoom | bool | false | Show zoom Navigation Control |
| fullscreenControlPosition | string | top-right | Set Fullscreen Control position |
| navigationControlPosition | string | bottom-right | Set Navigation Control position |

Marker

React Component that render a Marker. Extra props are directly passed to the Marker constructor

Props	Type	Default	Description
children	Node	null	Marker HTML DOM, default marker will be used if not provided
coordinates	Object	required	Coordinates of the marker
According to the LngLatLike model
draggable	bool	false	Allow user to drag’n’drop Marker
getRef	func		Callback function called with marker’s ref (useful for calling #moveToTop() function)
map	Object	required	Mapbox Map where marker will be added (can be obtained with MapboxMap#onLoad props fn)
onDragEnd	func		Callback function called on marker’s dragend
onMouseOut	func		Callback function called on marker or popup mouseOut
onMouseOver	func		Callback function called on marker or popup mouseOver
popup	Node		Popup attached to the marker, displayed on click to marker
popupAnchor	string	bottom	Popup anchor param
popupCloseButton	bool	false	Popup closeButton param
popupOffset	number		Popup offset param
popupOnOver	bool	false	Trigger popup show on mouse over (only available if children are provided, default marker cannot be bind)

Circle

React Component that render a Circle. Extra props are directly passed to the Marker constructor

Props	Type	Default	Description
coordinates	Object	required	Coordinates of the marker
According to the LngLatLike model
id	string	required	Identifier of circle, used to name the underlying layer
map	Object	required	Mapbox Map where marker will be added (can be obtained with MapboxMap#onLoad props fn)
onClick	func		Callback function called on circle’s click
paint	Object		Paint option of the layer
radius	number	required	Radius of circle, in kilometers
unit	string	kilometers	Unit of the radius. values can be : kilometers, meters, miles, feet

Helpers

We provide some helpers for interacting with Mapbox Map object, all in Helpers import.

import { Helpers } from react-mapbox-wrapper;

Helpers.convertRadiusUnit(580, 'meters');
// > { radius: 0.58, unit: 'kilometers' }

Helpers.getCircleData({ lat: 48.868526, lng: 2.3434886 }, 800, 'meters')
// > Coordinates for drawing a circle with a 800meters radius at given coordinates

Helpers.coordinatesAreEqual({ lat: 48.868526, lng: 2.3434886 }, [2.3434886, 48.868526]);
// > Check if given coordinates are equal, even in different format

Helpers.newBounds(coordinatesSouthWest, coordinatesNorthEast);
// > Create a new LngLatBounds from Mapbox library

Helpers.newBound(coordinates);
// > Create a new LngLatLike from Mapbox library

Helpers.drawGeoJSON(map, 'foodTruck', data, { 'fill-opacity': 0.2 }, undefined, 'fill');
// > Draw a geoJSON with given data and type. Can be used to also update geoJSON if layer already exist

Helpers.removeGeoJSON(map, 'foodTruck');
// > Remove the layer previously added with #addGeoJSON method

ReactJS: The Javascript Developer’s Guide

This article will walk you through the concepts you would need to know to step into the world of widely used ReactJS.

If you are here, you must be already a web developer with an understanding of javascript. You could be using just plain vanilla Javascript or could be a developer using libraries and frameworks already.

Let’s jump in and refresh some concepts to understand what React has in for us.

Library vs Framework

Libraries are primarily to help you get things done in an efficient way. jQuery was there to avoid complicated code and made it easy to do common functionalities like selecting items on the web page, creating elements, and appending them to either body or another element on the page.

As a web developer, we know there are a million ways to build a web page or a web application. Out of these million ways, there are certain ways that are scalable and can be supported at a large scale, so larger enterprises with varying developers with a wide range of skills can be onboarded and continue building the application.

For such scalability, a comprehensive set of tools to build a web application is necessary and those that get you done using javascript are called Frameworks. AngularJS/Angular is one such framework.

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

• For single line comment in JavaScript we have to use // (double slashes)
• For multiple line comments we have to use / * – – * /

<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>
