The process.setgroups() method is an inbuilt application programming interface of the process module which is used to set the supplementary group IDs.
process.setgroups( groups )
Parameters: This method accepts a single parameter as mentioned above and described below.

Return: It doesn’t return anything. For setting group Ids the Node.js process needs root permission as it is a privileged operation.
Note: This function will only work on POSIX platforms. Not available on windows or android platform so will cause to an error i.e. TypeError, setgroups is not a function.
Below examples illustrate the use of process.setgroups() method in Node.js:
