Loading App Dependencies Manually


Important: This approach must be used only in development environment. Since the release version of your application the app directory should self contain all used files.

In case on development environment your app runs the main process (executed by electron) not inside the /app folder. You may need to load the /app dependencies manually. Because the app dependencies are be placed at /app/node_modules and your main process that is running in a different directory will not have access by default to that directory.

Instead of duplicating the app dependencies in the development package.json it is possible to make the electron main process load the app dependencies manually with an approach like this:

// given this file is: /src/browser/main.js

const path = require('path')
const devMode = (process.argv || []).indexOf('--dev') !== -1

// load the app dependencies in dev mode
if (devMode) {
  const PATH_APP_NODE_MODULES = path.join(__dirname, '..', '..', 'app', 'node_modules')
  const Module = require('module')

  // for electron 16 or lower

  // for electron 17 or higher
  const nodeModulePaths = Module._nodeModulePaths
  Module._nodeModulePaths = (from) =>
