Node.js process.uptime() Method
The process.uptime() method is an inbuilt application programming interface of the process module which is used to get the number of seconds the Node.js process is running.
Syntax:
process.uptime();
Parameters: This method does not accept any parameter.
Return Value: It returns a floating-point number specifying the number of seconds the Node.js process is running.
Below examples illustrate the use of process.uptime() method in Node.js:
Example 1:
// Node.js program to demonstrate the // process.uptime() Method // Allocating process module const process = require('process'); // Printing the number of seconds // the Node.js process is running console.log(process.uptime()); |
Output:
0.0842063
Example 2:
// Node.js program to demonstrate the // process.uptime() Method // Allocating process module const process = require('process'); // Checking whether the method // exists or not if (process.uptime) { // Printing uptime() value console.log("The number of seconds the" + " Node.js process is running: " + process.uptime() + " seconds"); var i = 1000000; while(i--); console.log("The number of seconds the" + " Node.js process is running: " + process.uptime() + " seconds"); console.log("In whole seconds: " + Math.floor(process.uptime()) + " seconds"); } |
Output:
the number of seconds the Node.js process is running: 0.077 seconds the number of seconds the Node.js process is running: 0.087 seconds In whole seconds: 0 seconds
Note: The above program will compile and run by using the node filename.js command.
