vue + electron how to write a file to disk - vue.js

Question

I'm building a desktop app using Vue and Electron. I want to save a file from a vue component with some data introduced by the user. For doing that, I tried used fs node module inside an vuex action, but it got me error. Can't found that module. I know Vue is client side, but, I thought that at the moment of using with Electron it could work, but it does't. To init my app I used vue-cli and the command vue init webpack electron-vue.
I'm using vuex system and using vuex modules too, I've an actions.js file where I tried to use the fs module:
// import * as fs from 'fs'; I used this way at first
const fs = require('fs');
export const writeToFile = ({commit}) => {
fs.writeFileSync('/path/file.json', JSON.stringify(someObjectHere));
};
When I call this action from a Vue component, ex, Options.vue, I use the vuex dispatch system, and, in the created() method of that component:
this.$store.dispatch('writeToFile')
That's raised me the error above mentioned

Answer 1

to use File System in electron with Vue and WebPack, the file system instance has to be declared in the dist/index.html after execute the command "npm run build"
<script>
var fs = require('fs');
</script>
and in the vue component, it 's used fs like if it would have been declared in the vue file.
...
export const writeToFile = ({commit}) => {
fs.writeFileSync('/path/file.json', SON.stringify(someObjectHere))
};
...
while if not use it in electron or you write it in the index to dev, it throws an error.

Using window.require will help. This is the <script></script> part of the "App.vue" file:
import HelloWorld from './components/HelloWorld'
function writeToFileSync(filepath, content) {
if (window && window.require) {
const fs = window.require('fs')
fs.writeFileSync(filepath, content)
}
}
writeToFileSync('/usr/local/worktable/sandbox/msg.txt', 'Hello\nworld')
export default {
name: 'App',
components: {
HelloWorld
},
data: () => ({
//
})
}
The code above is test on:
macOS 10.15
Electron 11 (with nodeIntegration set to true)
Vue 2.6.11 (generated by vue create)
