(Node.js) Load JSON Object from HTTP Response Body

Demonstrates how to load the HTTP response body directly into a JSON object.

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJson method. Prior to v9.5.0.89, and application would need to first copy the HTTP response body to a Chilkat StringBuilder object by calling GetBodySb, and then load the JSON object by calling LoadSb.

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