This repository contains sample code for the following areas:

1. Creating a new BrowserWindow and how to show and destroy it from the MainProcess.
2. Sending data between RendererProcess and MainProcess in Electron app.
3. Using IPCRenderer and IPCMain objects.
4. Connecting Sqlite3 using Knex library.
5. Building and reading queries using Knex library.

The shortcut for showing dev tools on windows in Electron is Command + Alt + I on MacOS.

When sending data between RenderProcess and MainProcess, there are two important code pieces:

1. IPCMain and IPCRenderer
2. BrowserWindow.webContents.send()

WebContents contains events, etc. for a window. IPC means inter-process communication. The idea here is events. You can fire an event by using send() method along with data to pass, and the subscribers listening to it get the data passed.

Also, when I was working with Sqlite3, I got errors with it not being found. Therefore, I had to install electron-rebuild dev-dependency and rebuilt the electron with it by calling npm run rebuild. package.json has the setting for the rebuild command.
