Google Chrome’s “Developer Tools” is what many developers use to debug client-side code. Chrome Logger is an extension that brings server-side code debugging to this tool. It has libraries for PHP, Python, Ruby, .NET, ColdFusion and Node.js. Also, new ones can be created with the documentation provided.
These libraries simply enable us to view variables in Developer Tools.
Although each server-side language has their stronger debugger tools, using the same logging tool for client and server-side makes sense.
