Electron application cannot resolve any node module that is added to webpack externals












1















I am trying to build an Electron application using Vue.js.
I am using webpack-dev-server to run the electron app in development mode.



In the webpack config I am adding all my node_modules to the externals array since I do not want them to be bundled.



The webpack development server gets started successfully without any error and the application is also launched as expected but I get the following error in the console.



Uncaught Error: Cannot find module 'frappejs'.

Note: This is not the only module that cannot be resolved. All the modules that I have added to the webpack externals arrays could not be resolved.



If I do not add them to the externals array, the node_modules are detected and the above error disappears.



Another thing that I have noticed is that if I replace
const frappe = require('frappejs'); with
const frappe = require('../../node_modules/frappejs');

The error disappers in this case as well when I am explicitly pointing to the node_modules directory.



What maybe the reason for this behaviour?
