kiosk and bank system for hassle-free management of accounts, groups, products and transactions

• Create accounts with balances and organize them into groups
• Create products (along with product images) and organize them into categories
• Select Products to add them to the Shopping Cart or use a 2D-Barcode Scanning device
• Persist all transactions to disk in a sequence of traceable transactions

Electron is used to wrap this application into a browser container for native cross-platform use. React is used along with the UI component library Ant Design and Redux is used for state-management - specifically redux-toolkit.

All transactions (add account, add product, checkout products, ...) are persisted to a JSONL file. When the application is opened, all historic transactions are replayed to generate the current state (e.g. account balances). The idea is to keep a complete explainable history that can be inspected in a separate view. Consistency between transactional data and current state are ensured. Historical events can be used to derive statistics.

Once checked out, the project dependencies can be installed with

npm i

and the local development server is started with

npm start

Please refer to the electron-forge docs for instructions on how to create a distributable build.

• Create a products page where categories and products can be created
• Allow editing of groups, accounts, categories and products
• Create a shopping cart that is visible
• Allow use of a USB barcode scanning device by catching EAN keyboard inputs in the product view
• i18n
• In case the event sourcing gets slow with many transactions, maybe implement snapshotting so we don't have to replay all events on every application start
