Things I have learned while building with Electron

1. Electron has 2 separate processes one for main and one is a renderer process. Main is based on node dealing with your computer hardware and need to be kept secure, the renderer one is for UI only. You need to debug seaperatly for each one.

2. Your database connection will be a pain to set up if you don't understand some concepts:

3. How can we actually fully connect front-end to this database?

4. In main.js, ipcRenderer isn’t available—it’s for the renderer process. This will cause a syntax error or runtime error (ipcRenderer is not defined).

In next version I will update with the ability to backup automatically each 5min 😃.

Integrated Sync Triggers:

On app startup (app.whenReady): Initializes the sync setup and syncs from OneDrive to ensure the app uses the latest DB. On app close (before-quit): Syncs to OneDrive if mainWindow exists (post-login)

Useful commands:

1. To delete the dist foler by force (the folder that shows after you build the app):

Remove-Item -Recurse -Force .\dist
