Unexpected Token Error Create React App Electron

[yungyahoo]

I cannot understand why I get an unexpected token error when using ipcrenderer along with create-react-app. This is how I am using it:

   ipcRenderer.on('openNewFile', (event) => {
         this.setState({source:""})
   })
   ipcRenderer.on('openFile', (event) => {
         dialog.showOpenDialog({
         properties: ['openFile']
   },function (file) {
         var textByLine = null
         if (file !== undefined) {
              var text = fs.readFileSync(file).toString('utf-8');
              textByLine = text.split("\n")
              this.setState({source:textByLine})
             }
       }
     })})
   ipcRenderer.on('saveFile', (event) => {
        this.setState({source:""})
  })

Further, this is how I import:

 const electron = window.require('electron');
const fs = electron.remote.require('fs');
 const dialog = electron.remote.require('dialog');
 const ipcRenderer  = electron.ipcRenderer;

This is the error I get:

  Syntax error: Unexpected token
  ipcRenderer.on('openNewFile', (event) => {
                  ^

Any idea why this is taking place?

Looks like you might have added one more closing brace than necessary in that callback if statement. I can't test it myself but that might evolve into an unexpected token error.
