process
process 객체에 대한 확장 기능.
process 객체는 Electron에서 약간 추가적인 기능이 있으며 API는 다음과 같습니다:
Events
Event: 'loaded'
Electron 내부 초기화 스크립트의 로드가 완료되고, 웹 페이지나 메인 스크립트를 로드하기 시작할 때 발생하는 이벤트입니다.
이 이벤트는 preload 스크립트를 통해 node 통합이 꺼져있는 전역 스코프에 node의 전역 심볼들을 다시 추가할 때 사용할 수 있습니다:
// preload.js
const _setImmediate = setImmediate;
const _clearImmediate = clearImmediate;
process.once('loaded', () => {
global.setImmediate = _setImmediate;
global.clearImmediate = _clearImmediate;
});
Properties
process.noAsar
Setting this to true can disable the support for asar archives in Node's
built-in modules.
process.type
Current process's type, can be "browser" (i.e. main process) or "renderer".
process.versions.electron
Electron's version string.
process.versions.chrome
Chrome's version string.
process.resourcesPath
Path to the resources directory.
process.mas
For Mac App Store build, this property is true, for other builds it is
undefined.
process.windowsStore
If the app is running as a Windows Store app (appx), this property is true,
for otherwise it is undefined.
process.defaultApp
When app is started by being passed as parameter to the default app, this
property is true in the main process, otherwise it is undefined.
Methods
The process object has the following method:
process.crash()
Causes the main thread of the current process crash.
process.hang()
Causes the main thread of the current process hang.
process.setFdLimit(maxDescriptors) macOS Linux
maxDescriptorsInteger
Sets the file descriptor soft limit to maxDescriptors or the OS hard
limit, whichever is lower for the current process.
process.getProcessMemoryInfo()
Returns an object giving memory usage statistics about the current process. Note that all statistics are reported in Kilobytes.
workingSetSize- The amount of memory currently pinned to actual physical RAM.peakWorkingSetSize- The maximum amount of memory that has ever been pinned to actual physical RAM.privateBytes- The amount of memory not shared by other processes, such as JS heap or HTML content.sharedBytes- The amount of memory shared between processes, typically memory consumed by the Electron code itself
process.getSystemMemoryInfo()
Returns an object giving memory usage statistics about the entire system. Note that all statistics are reported in Kilobytes.
total- The total amount of physical memory in Kilobytes available to the system.free- The total amount of memory not being used by applications or disk cache.
On Windows / Linux:
swapTotal- The total amount of swap memory in Kilobytes available to the system.swapFree- The free amount of swap memory in Kilobytes available to the system.
Properties
process.noAsar
이 속성을 true로 지정하면 Node 빌트인 모듈의 asar 아카이브 지원을 비활성화 시킬
수 있습니다.
Methods
process 객체는 다음과 같은 메서드를 가지고 있습니다:
process.crash()
현재 프로세스의 메인 스레드에 크래시를 일으킵니다.
process.hang()
현재 프로세스의 주 스레드를 중단시킵니다.
process.setFdLimit(maxDescriptors) macOS Linux
maxDescriptorsInteger
현재 프로세스 파일 디스크립터의 제한 값을 소프트 제한 maxDescriptors의 값이나 OS 하드
제한 중 낮은 값으로 설정합니다.
