@napi-rs/nice

Get and set process priority on Unix and Windows via Node.js.

Usage

nice

On Unix, nice() adds inc to the nice value for the calling process. (A higher nice value means a low priority.) Only the superuser may specify a negative increment, or priority increase. The range for nice values is described in getpriority(2).

On Windows, it uses the SetThreadPriority function.

// on Unix
import { nice } from '@napi-rs/nice'

nice(2)

// on Windows
import { nice, WindowsThreadPriority } from '@napi-rs/nice'

nice(WindowsThreadPriority.THREAD_PRIORITY_ABOVE_NORMAL)

getCurrentProcessPriority

This function gets the priority of the current process. On Unix, it uses the getpriority(2).

On Windows, it uses the GetThreadPriority function.

Priority Constant	Value	Description
THREAD_MODE_BACKGROUND_BEGIN	0x00010000	Begin background processing mode. The system lowers the resource scheduling priorities of the thread so that it can perform background work without significantly affecting activity in the foreground.
		This value can be specified only if hThread is a handle to the current thread. The function fails if the thread is already in background processing mode.
		Windows Server 2003: This value is not supported.
THREAD_MODE_BACKGROUND_END	0x00020000	End background processing mode. The system restores the resource scheduling priorities of the thread as they were before the thread entered background processing mode.
		This value can be specified only if hThread is a handle to the current thread. The function fails if the thread is not in background processing mode.
		Windows Server 2003: This value is not supported.
THREAD_PRIORITY_ABOVE_NORMAL	1	Priority 1 point above the priority class.
THREAD_PRIORITY_BELOW_NORMAL	-1	Priority 1 point below the priority class.
THREAD_PRIORITY_HIGHEST	2	Priority 2 points above the priority class.
THREAD_PRIORITY_IDLE	-15	Base priority of 1 for IDLE_PRIORITY_CLASS, BELOW_NORMAL_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, ABOVE_NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority of 16 for REALTIME_PRIORITY_CLASS processes.
THREAD_PRIORITY_LOWEST	-2	Priority 2 points below the priority class.
THREAD_PRIORITY_NORMAL	0	Normal priority for the priority class.
THREAD_PRIORITY_TIME_CRITICAL	15	Base priority of 15 for IDLE_PRIORITY_CLASS, BELOW_NORMAL_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, ABOVE_NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority of 31 for REALTIME_PRIORITY_CLASS processes.
