Write files

[tezqa]

Hi,

How to use the node fs module to write file when the game is running in Electron?

Thanks for your help!

Hi @tezqa, I see no reason using fs as usual shouldn't work. w3schools has some good and easy to follow and try out examples.

Hi @rroylance

I had an error with webpack: Module not found: Error: Cannot resolve module 'fs'

But I solved by adding:

target: 'node',

But now I have a EACCESS error when trying to write my file.

Ok forget it, it was because of the path i chose. Thanks :)

Hi @rroylance,

I'm trying to access to Electron from the app code in order to get specifics user paths.

import { app } from 'electron'
app.getPath('documents')

But I got undefined when I try to import Electron. Any idea?

Hi @tezqa, you may need to require electron rather than importing it.

import app = require('electron'); // or something along these lines

I have tried to use require and import, but without success...

Error: Electron failed to install correctly, please delete node_modules/electron and try installing again

It fails because of the node_modules/electron/index.js file:

var pathFile = path.join(__dirname, 'path.txt')

if (fs.existsSync(pathFile)) {
  module.exports = path.join(__dirname, fs.readFileSync(pathFile, 'utf-8'))
} else {
  throw new Error('Electron failed to install correctly, please delete node_modules/electron and try installing again')
}

Indeed, __dirname is equal to / when the app is running.

I suppose there is something to configure in the webpack config.

Ok I ended up with the Nodejs os module to find the correct path. I don't use Electron.
But it's strange that nobody here needs to use Electron within the app.

Hmm. Glad you got it working none the less. Unfortunately I don't even use the electron portion of this project at all so I'm pretty unfamiliar with it.
