JavaScript Execution Context (electron-process-type)

A function which returns the execution environment of your code.

Detect the engine which is executing your code:
- NodeJS runtime
- Browser runtime
- Electron runtime

detect which are the environments / API(s) available :
- NodeJS
- Browser
- Worker
- Electron

Runtime | Node | Browser | Electron
-------------- |:----:|:---------:|:--------:|
NodeJS API | Node.js process | | Electron Node.js process
Browser API | | Browser | Electron Renderer or preload
Worker API | WorkerThread | WebWorker | Electron Worker
Electron API | | Electron preload | Electron main process

Worker, ServiceWorker, SharedWorker detection is still experimental/partial

This API works in any kind of processes (not only Electron): Electron, Node, Browser, ...

In Electron, the detection uses the Electron API process.type but there is some limitations.
It does not work properly in following contexts :
* in a node process
* in a renderer when Chromium is in sandbox (--enable-sandbox=true)
* in a renderer when Renderer is in sandbox=true
* in a renderer when nodeIntegration=false
* in preload file of a renderer

return the current execution context.

function IsContextNode(): boolean

Check if you are running in a NodeJS context: pure NodeJS process, Electron NodeJS process, Electron Main NodeJS process.

function IsContextBrowser(): boolean;

Check if you are running in a Browser (Navigator) context: pure Browser, Electron browser.

function IsContextWorker(): boolean;

Check if you are running in a Worker.

function IsProcessElectron(): boolean;

Check if you are running in a Electron process: Electron NodeJS process, Electron Main NodeJS process, Electron browser.
