Why did electron not create file? - electron

Question

I'm building an app on electron and now I'm trying to create a simple file.
Here's the JS:
const app = require("electron").remote;
var dialog = app.dialog;
var fs = require("fs");
document.getElementById('save_project').onclick=() => {
dialog.showSaveDialog((filename) => {
if(filename === undefined){
console.log("You didnt save the file");
return;
};
var content = "hello there";
fs.writeFile(filename, content, (err) => {
if(err) console.log(err);
alert("The file has been successfully saved.")
})
});
};
This window will open as supposed:
Then, I wrote for instance: "hello.txt" on the name input and clicked save.
There's no log written on the console neither a file written in the directory
Edit:
with this js, happens the same ():
const fs = require("fs");
const {dialog} = require("electron").remote;
document.getElementById("save_project").addEventListener("click", () => {
dialog.showSaveDialog((filename) => {
if(filename === undefined){
console.log("nop");
return;
}
fs.writeFile(filename, content, (err) => {
if(err){
console.log(err);
return;
}
alert("file created");
});
});
}, false);
Edited:
Here's the createWindow()
function createWindow () {
// Create the browser window.
const mainWindow = new BrowserWindow({
width: 1920,
height: 1080,
webPreferences: {
preload: path.join(__dirname, "preload.js"),
nodeIntegration: true
},
});
const childWindow = new BrowserWindow ({ width: 1600, height: 800, parent: mainWindow, modal: true, show : false});
// and load the index.html of the app.
mainWindow.loadFile("index.html");
childWindow.loadFile("welcome.html");
childWindow.once("ready-to-show", () => {
childWindow.show();
});
// Open the DevTools.
mainWindow.webContents.openDevTools();
}

Basically, from what i understood, "dialog.showSaveDialog((filename).." this was kinda blocking... i fixed by using:
const {dialog} = require("electron").remote;
let filename = dialog.showSaveDialogSync()
if(filename === undefined){
console.log("filename undefined");
return;
}else{
console.log(filename)
saveAsToFile(filename, ...);
}
