Under the hood
Built with
- Electron
- Express
- SQLite (sql.js)
- EJS
- PDFKit
- Excel export
Electron wraps a local Express server, with SQLite stored in a single file the owner can back up. electron-builder makes a Windows installer. These screens show seeded demo data, not the client’s records.
