Node.js process.debugPort Property
The process.debugPort property is an inbuilt application programming interface of the process module which is used to get the debugging port used by the debugger if enabled.
Syntax:
process.debugPort
Return Value: This property returns an integer value that specifies the debugging port used by the debugger if enabled.
Below examples illustrate the use of process.debugPort property in Node.js:
Example 1:
// Node.js program to demonstrate the // process.debugPort property // Include process module const process = require('process'); // Printing process.debugPort console.log("debug port is " + process.debugPort); |
Output:
debug port is 9229
Example 2:
// Node.js program to demonstrate the // process.debugPort property // Include process module const process = require('process'); // Printing process.debugPort property value var debug_port = process.debugPort; // Check whether debug port is defined if(debug_port != undefined){ console.log("debug port is defined"); console.log("debug port is " + debug_port); }else{ console.log("debug port is not defined"); } |
Output:
debug port is defined debug port is 9229
Note: The above program will compile and run by using the node filename.js command.
