CARTO for deck.gl

​View on Github​
Introduction
​deck.gl is one of the most popular Open Source map visualization libraries and is the preferred library to use with CARTO. With deck.gl and CARTO you can create highly scalable applications that visualize location data in many different ways. We have created a submodule @deck.gl/carto that you can use to work with CARTO datasets and tilesets in a very easy and straightforward way.
The CartoLayer is the deck.gl layer that provides the integration with the CARTO platform. This layer can be used from different frameworks like React, Angular, or Vue.js. It works with both CARTO 2 and CARTO 3.
About Carto Platform Versions
In this documentation we use the term “CARTO 3” to refer to the latest version of the CARTO platform launched on October 2021, and “CARTO 2” to refer to the previous version. We provide examples for both versions and we add notes when there are differences in the way you need to work with each of them. Note that each platform version has its own set of account credentials.
We have provided many examples that you can study to see how to use the deck.gl library with our platform. Please take a look at the examples section in this site and the examples in the viz-doc repository.
It is important that you begin by learning the core deck.gl concepts. Please check the official deck.gl documentation site.
Are you a React user?
If you are a React user and want to build a web application using CARTO, we recommend you to check CARTO for React.
What does CARTO provide
Starting with version 8.3, deck.gl includes a submodule @deck.gl/carto for integration with the CARTO platform. This module provides all that you need to:
Access data from the CARTO platform. Using the setDefaultCredentials function you supply the parameters needed to connect with the CARTO platform, then you use the CartoLayer to visualize the datasets.
Use CARTO basemaps. With deck.gl you can choose between different basemaps for your visualizations. CARTO provides a set of free basemaps from OpenStreetMap, but you can also use Google Maps, Mapbox, or any other provider with MVT support.
Create data-driven visualizations. Using our style helpers you can easily create choropleth maps for numerical and categorical data.
Installation
Two different flavors are provided:
Scripting. Useful to build prototypes.
NPM Module. You’ll use the NPM module in React applications, Vanilla JavaScript applications, or applications using other frameworks such as Angular or Vue.js.
Using scripting
If you want to use the scripting API, you need to add to your HTML page both the deck.gl JavaScript bundle and the CARTO submodule JavaScript bundle:
<script src="https://unpkg.com/deck.gl@latest/dist.min.js"></script>
<script src="https://unpkg.com/@deck.gl/carto@latest/dist.min.js"></script>
In the Examples section you can find interactive examples using the scripting API, like the Hello World example:
Using the NPM module
You can use the NPM module for Vanilla JavaScript applications or for applications using frameworks like React, Angular, or Vue.js.
You just need to add the @deck.gl/carto dependency to your project using the package manager. When you install this dependency, the CARTO submodule is already included:
npm install @deck.gl/carto
In the Build a public application guide in this documentation we have a fully working repository that you can use as a starting point with NPM.
