Using 'express' inside Electron main thread, cannot find module
You can run Express server inside Electron. Here is a sample repo for running express inside Electron.
You can fork a child process to run express app as follows
app = require("electron").remote.app),node = require("child_process").fork( `${app.getAppPath()}/express-app/bin/www`, [], { stdio: ["pipe", "pipe", "pipe", "ipc"] });The express app used here is a generated one using express-generator.
The problem with your approach is that you are maintaining a single package.json file for both Electron and Express. Checkout Electron-React-Boilerplate, here i have two separate npm installation locations one is for Electron alone and other is for React stuffs. Electron-packager and Electron-builder works using this pattern. This is the reason why your process on main thread throws
Error: Cannot find module 'express'
