Migrating from 3.x

The ArcGIS Maps SDK for JavaScript is Esri's premier web mapping SDK and the successor to version 3.x of ArcGIS API for JavaScript that was retired in 2024. Since version 4.x of the JavaScript Maps SDK has fundamental differences in architecture and coding patterns, migrating a solution from version 3.x often requires an application re-write. This topic aims to assist developers who are transitioning their 3.x-based solutions to the JavaScript Maps SDK.

There are many resources available to help migrate from 3.x to 4.x, including:

• Getting started with 4.x: A guide to help you get started with 4.x.
• Components: Information about the components available in 4.x, including the arcgis-map (2D) and arcgis-scene (3D) components.
• Tutorials: Step-by-step exercises that teach the basics of getting started with JavaScript Maps SDK.
• Samples: Play around with the samples to get a feel for JavaScript Maps SDK capabilities.

Functionality matrix

The functionality matrix provides a comparison of 3.x and 4.x to help you find the equivalent functionality in 4.x. The tables below are organized by module, with the 3.x module name in the first column and the 4.x equivalent in the second column. The third column provides additional notes and information about the differences between the two versions. The tables are not exhaustive, but they cover the most commonly used modules and functionality.
