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.
