How to Utilize Upgrade Adviser to Upgrade Your Ext JS Apps

Upgrading Ext JS from versions 3.x, 4.x, 5.x, or 6.x to latest 7.8 is a significant task. It requires reviewing legacy code, handling deprecated features, and resolving compatibility issues across multiple versions—challenges that can take considerable time and effort for development teams.

To simplify the upgrade process, Sencha provides the Upgrade Adviser—a tool that scans your Ext JS application code to identify issues that need fixing before upgrading. Whether you’re making a major jump from versions 3.x or 4.x to 7.8 or keeping up with incremental updates, the Upgrade Adviser helps reduce risks, save time, and ensure a smoother transition.

What is the Ext JS Upgrade Adviser?

The Ext JS Upgrade Adviser is a powerful tool designed to help developers prepare their applications for upgrading to newer versions of Ext JS. It scans your application’s code to identify potential issues that need attention before upgrading. These issues include:

• Removed Methods: Flags methods that are no longer supported in newer Ext JS versions.
• Private APIs: Identifies the use of private APIs, which should be replaced with public alternatives.
• Deprecated Configs and Properties: Flags outdated configurations and properties that require updating for compatibility.

The Upgrade Adviser uses a custom ESLint plugin built specifically for Ext JS, enabling automated checks. It can be run from the command line or integrated into an IDE, offering developers the ability to fix issues automatically or receive detailed recommendations for resolving upgrade-related problems.

This tool ensures a smoother, more efficient upgrade process by addressing potential compatibility issues before they affect your application.
