ArcGIS JavaScript 3.x to 4.x MIGRATION ANALYZER

Why EsriCode?

EsriCode is a specialized toolset designed to streamline the migration process from ArcGIS JavaScript SDK 3.x to 4.x.

We provide line-by-line guidance, relevant documentation links, and code examples to streamline your migration process.

The Esricode tool helps developers facilitate the transition from single Map instances to the new Map-MapView pattern, transform legacy widgets to align with the modern architecture, convert AMD module patterns to ES modules, update deprecated layer and symbol implementations, and modernize event handling systems. 

Our Migration Analyzer streamlines your ArcGIS JS upgrade and saves you valuable development time. Through intelligent pattern detection, instant documentation access, and ready-to-use code suggestions, you can migrate with confidence knowing you’re following proven patterns and best practices. This not only accelerates your migration but turns it into a learning opportunity, providing detailed explanations and up-to-date code examples that enhance your team’s expertise with the 4.x API.

our mission

Our mission is to empower Esri developers with intelligent solutions that simplify the complex transition between these platforms.

We’ve developed a comprehensive migration analyzer that:
– Processes JavaScript and HTML files to identify critical migration points
– Provides side-by-side code comparisons between 3.x and 4.x versions
– Incorporates the latest Esri migration guidelines
– Offers structured code examples

Our platform distills over 7,000 lines of Esri migration documentation into actionable, targeted recommendations. By focusing on essential code changes and providing modern equivalents for deprecated functionalities, we help development teams:
– Reduce migration time and costs
– Minimize the risk of errors during transition
– Maintain application functionality throughout the upgrade process
