(Node.js) Transition from ZipEntry.NextEntry to ZipEntry.GetNext

Provides instructions for replacing deprecated NextEntry method calls with GetNext.

Note: This example requires Chilkat v11.0.0 or greater.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS
