QUESTION
I'm working on a software project which I've created with Electron and React. I didn't create the project from scratch, I am using a boilerplate which uses Webpack.
The software is for managing (selling & redeeming) vouchers, so I also have to print some receipts. Using the printer over network is working fine, just as it should. For printing I'm using the node-thermal-printer
package (https://www.npmjs.com/package/node-thermal-printer).
But some of the printers don't have a network interface, just USB or Serial.
When using the node-thermal-printer
with a USB connected printer, you have to provide a "driver" to be able to print. They suggest either the electron-printer
or printer
module, which both seem to be native NodeJS modules.
The boilerplate seems to compile the native modules for the architecture that is currently used and creates a *.node
file, which is copied to the .wepback/
folder during the build phase. But as soon as I want to use the package, I get an error that the module could not be found.
I'm importing the module with the following line:
const printerDriver = require("printer");
When running npm start
the native dependencies are compiled and a node_printer.node
file is created and copied to .webpack/main/native_modules/lib/node_printer.node
.
As soon as I click the button for printing, I receive the following error:

QUESTION
I have spent multiple days reading through tickets and documentation trying to find a solution to this issue and no suggestion has worked. It seems a major oversight or I'm a complete dummy.
Simply, what I want to do is access the electron api from within the application, for example I would like a button that one could click to close, resize etc. the window via the BrowserWindow object from within the render/preload scripts.
I am compiling it via electron forge w/ webpack from example repo provided by electron forge (as opposed to separate webpack), I have nodeIntegration: true
, contextIsolation: false
and enableRemoteModule: true
, the package.json
also has these options set.
This is the starting project I've used: https://www.electronforge.io/config/plugins/webpack
From reading other tickets the generally recommended way is to require the remote
module via various methods, get the window object and close / execute your action. The issue being this always returns null
when using:
const remote = require('@electron/remote')
const remote = require('electron').remote
const { remote } = require('electron')
I've tried various sources but for example nothing in this ticket works: Atom Electron - Close the window with javascript
I also read this article that seems to say the remote
module was deprecated and is no longer used, however the code in that doesn't work either: https://www.npmjs.com/package/@electron/remote
I have created a git repo with the code I'm trying to use: https://github.com/MajorFailz/electron-problem-example
Please help! I can't really continue development on my project using electron if I can't control the application from within the application. I'm perfectly happy to accept if I've been dumb somehow and missed something vital or fundamental, but as I say it feels like these are the first things any electron noobie would need to know but I'm lost =/
Bonus points if you can provide me a demonstrable example of it working I could look at.
Thanks in advance!
Edit: versions from package

Answered 2021-Dec-16 at 16:26Thanks to @evolutionxbox 's comments I managed to fix this with the following.
npm run install --save @electron/remote
Then in main.js add the following line:
require('@electron/remote/main').initialize()
Then finally when you're creating your window in the main process add this:
require("@electron/remote/main").enable(mainWindow.webContents)
Now I'm getting the BrowserWindow object when I'm asking for it! Woop!
QUESTION
I'm working on a React application where I want conditional rendering of FontAwesome icons, but at the moment it's not changing when it should.
I inspected elements and found that FontAwesome is commenting out the React component and replacing it with the svg of the icon, so when I go back to change the FontAwesome icon in React, it has no effect. Below is an example of this

Answered 2021-Aug-24 at 16:22This issue was solved once I changed the import to import '@fortawesome/fontawesome-free/css/all.css';
and made some adjustments to the config.
QUESTION
I recently tweaked my webpack modules in my React/Electron.js project to compile less files using less-loader, css-loader, and MiniCssExtractPlugin.loader instead of the style-loader since there is no window defined during part of the compilation, but now the font awesome icons are showing up as boxes and I'm not sure why that is.
The font awesome icons showed up fine when I had style-loader instead of MiniCssExtractPlugin.loader, but I only made this change for loading .less files, and not anything else, so I'm confused why this was affected.
I've tried adding .fa, .far, .fas { font-family: FontAwesome !important; }
to my index.less file as suggested here, but this didn't help at all.
I also tried adding in the font-awesome-loader
, but this seems to have a dependency of sass-loader@*
, which I'm not using.
What's causing Font Awesome to load with style-loader but not MiniCssExtractPlugin.loader? I've included my webpack modules and my font-awesome import below:

QUESTION
I'm trying to include a VLC video playing in my Electron app, which is possible through WebChimera.js. This package is distributed a bit weirdly (to me at least), to use it you need to require wcjs-prebuilt, specify some settings in package.json and configure Webpack to allow importing .node files as explained in this Wiki page for WebChimera.js.
However I believe this Wiki page is outdated, as loaders isn't a valid key anymore in a Webpack config. I'm not very experienced using Webpack so most of this is new to me. Also note that this Wiki explanation used a fork of node-loader, although this fork seems to be merged to the actual node-loader now (?).
I now use this Webpack config:

correctly or video won't play.

Since I used Electron forge webpack plugin, when I execute npm start
, it will cause an error after step Compiling Preload Scripts. It says the error is inside Forge.
I check it out, it's an error in file watcher api, that mainCompilation.fileSystemInfo
is undefined, so it cannot read prop createSnapShot function.
What should I do to resolve this error and start my app?

I have enabled node.js on one of my domains on a shared server. All management actions are done from the console of Plesk Obsidian 18.0.20. I see that Plesk manages nodejs through Phusion Passenger 6.0.6.
I am unable to create an express server. The startup of my nodejs app fails with the message:

Answered 2021-Mar-22 at 08:48I managed to solve the issue. The root of the problem is that Plesk expects the package.json file to be in the domain root. Instead it was in a subdir.

Answered 2021-Jan-08 at 13:09Ok, I just deleted the .next folder prior to building the production version via npm run build

Does anyone know why this error is occurring only on the production server and not when I run it locally?

Answered 2020-Nov-30 at 12:03Do you use Docker? If yes, this question on Stack Overflow may already give you the answer.
TLDR: The .dockerignore file should include your node_modules
folder.
