ArcGIS Maps SDK for JavaScript

All things Web Development at the Esri Developer and Technology Summit 2026!

By Sneha Suresh

We are excited to see you at the Esri Developer & Technology Summit 2026! Whether you’re joining us in-person or online, you’ll discover extensive technical sessions and inspiring demos. You’ll also have the opportunity to connect with the team behind ArcGIS Maps SDK for JavaScript, Calcite Design System, and ArcGIS Arcade to get all your questions answered.

Here’s a quick guide to help you navigate the conference and make the most of every session.


Build with Web Components

ArcGIS Maps SDK for JavaScript web components are custom HTML elements (e.g, <arcgis-map>) that wrap SDK functionality into reusable UI building blocks. Built using web standards (Custom Elements, Shadow DOM, and HTML Templates), they work natively in modern browsers.

This 4-part series takes developers from core concepts and web components, through framework integration with React and Vite, to building user experiences with Calcite Design System, and finally mastering theming, branding, and customization with design tokens and component slots, providing a complete path to building professional, production-ready web mapping applications.


Visualization

Discover how to transform spatial data into compelling visual stories with the ArcGIS Maps SDK for JavaScript. These sessions highlight practical approaches to 2D data visualization, creative and custom rendering techniques, powerful 3D mapping on the web, and dynamic time-based visualizations, including real-time and historical data, giving developers the tools to build engaging, expressive mapping experiences.

These sessions show developers how to get the most out of layers and data with the ArcGIS Maps SDK for JavaScript. You’ll learn to optimize Feature Layer performance, run powerful client‑side queries, visualizations, and analytics directly in the browser, and work with modern formats like Parquet, GeoJSON, CSV, GeoTIFF, and OGC services. The lineup also highlights imagery workflows, Cloud Optimized GeoTIFFs, client‑side raster processing, and interactive data exploration with the Feature Table, equipping you to build high‑performance, data‑driven web apps at scale.


Build compelling web applications with ArcGIS

These sessions deliver an end‑to‑end view of web app development—from automating data ingestion and managing services to authoring web maps with cartographic best practices and building custom 2D and immersive 3D apps. Explore real-world app showcases, learn core web architecture and low code options, and engage directly with the SDK team in an open, audience driven Q&A.
