Database Support

[Karna98]

Description

Added support of better-sqlite3 database.

Additional Context

• Downgrade Electron from ^14.0.0 to ^13.0.0.
  Refer to discussions and related links to issues mentioned in the discussion.
  In future, once the electron-rebuild fixes the different node version issues while compiling, we will upgrade the Electron version.
• PR contains a simple demonstration of integrating the database and performing a basic insert query and retrieving data queries from the database.
• PR also demonstrates how to handle database migrations.

Testing Database and Migration

1. Inside the Notes folder, run npm install to install all the dependencies.
2. Then run npm run native-dep. This will install better-sqlite3 and compile based on local OS.
3. Once done successfully, run the npm run dev command.
4. Once the Notes application launches, the notes.sqlite file will be created in the src/main/sql folder.
5. Click on the Request ENV From Main button, this will insert logs in the database. Then click on the Refresh Logs button to retrieve data from the database.
6. To perform the migration, kill the app. Update the following changes in code

   # src/main/sql/util.ts
   
   // Latest Schema Version.
   export const SCHEMA_VERSION = 1;    // <-- Update to 1
   

7. Rerun the npm run dev command.
8. Once the Notes application launches, click on the Refresh Logs button and observe the changes.
