Six smart steps to configure Mapbox with ReactJS

Mapbox provides custom maps, search and navigation. It supports many platforms. The tool is powered by programmers as well as millions of devices providing Location Data. It provides developers a platform and a toolset to build customized applications where location-based data can be used to meet a variety of business requirements.
A typical scenario where Mapbox is used:
A service provider uses Mapbox to track locations of their assets or employees in order to provide real-time information to customers or for operational monitoring. This could be a restaurant delivery service, an international transport company or even a fleet operator in a city.
Customizing Mapbox
One of our clients provides data services to monitor the health of agricultural farms. They wished to offer compelling data visualization of agricultural farm images along with other details. We customized mapbox to render this information on the web and mobile devices. There are SDKs available for the Web, iOS and Android.
In this article, we share how we configured mapbox in React JS using custom style to add new fonts, custom icons and publish these styles.Following are the steps involved –
1. Steps to generate the token number and style in Mapbox

• a. Create an account on https://account.mapbox.com
• b. Log in to your account
• c. On the Dashboard look for the Default public token. This Token number can be used for configuration in the Web App. You need to remember that this token number is public and easily accessible from the developer tab.
• d. To get the private Token click on the button ‘Create a Token’ you will get a form. Enter the ‘Token name’ and select the desired ‘Public Scope’ and the ‘Secret Scopes’.
  
• e. Note: – This token will only be accessible from the specific URLs that we add while generating the Token.
  
• f. Now add the list of comma-separated URLs into the URL field and click on the ‘Create Token’. Next you will be asked to confirm with your account password.
• g. You will find the private token at the bottom of the Token list.
  

2. Steps to configure React JS app with Mapbox

• e. Add the map to your Web App.
  • i. var mapboxgl = require(‘mapbox-gl/dist/mapbox-gl.js’);
  • ii. mapboxgl.accessToken = ‘Your Token number’;
  • iii. var map = new mapboxgl.Map({
  • iv. container: ‘YOUR_CONTAINER_ELEMENT_ID’,
  • v. style: ‘mapbox://styles/mapbox/streets-v11’ // Default style link
  • vi. });
• f.  Now you are done with the configuration.
