Answer: How to pass parameters from main process to render processes in Electron

This post references a Stack Overflow discussion regarding parameter passing between Electron’s main and renderer processes.

The question addresses a common challenge in Electron applications: how to safely and efficiently pass data from the main process to renderer processes.

The Problem

In Electron, the main process and renderer processes run in separate contexts for security reasons. This separation means you can’t directly share variables between them.

Solution Approaches

Common approaches to solve this include:

  1. IPC (Inter-Process Communication) - Using ipcMain and ipcRenderer modules
  2. Remote module - Though deprecated in newer Electron versions
  3. Preload scripts - Exposing specific APIs to the renderer via contextBridge
  4. URL parameters - Passing data through the window’s URL when creating BrowserWindow
