Addressed Issues:

Fixes #187

Screenshots:

  • Settings → Invoice Backup section showing the Export Backup and Import Backup buttons.
  • Successful backup export/import verification.
  • Invalid and malformed backup files are rejected with validation errors.

Additional Notes:

Implemented local invoice backup and restore using the existing IndexedDB backup library.

The backup flow:

  • Exports the Chainvoice invoice store as JSON.
  • Validates backup metadata, database schema, and invoice records before import.
  • Merges valid backup data into the existing IndexedDB store.
  • Notifies the Sent and Received invoice views after a successful import so they can refresh.

Walkthrough

Changes

The PR adds validated local invoice backup export and import. It exposes the feature in Settings and refreshes Sent and Received invoice lists after a successful import.

Invoice backup processing

Layer / File(s) Summary
Validate and process invoice backups
frontend/src/services/invoiceStorage/invoiceBackup.js
Validates backup metadata, schema, and invoice records. Export initializes the database and includes only the invoice store. Import validates JSON files, merges data, and dispatches a storage update event.
Expose backup controls in Settings
frontend/src/components/InvoiceBackupSettings.jsx, frontend/src/page/Settings.jsx
Adds export and import controls with loading states, toast messages, JSON file selection, and input reset behavior. Registers the Invoice Backup Settings section.
Refresh invoice lists after import
frontend/src/page/SentInvoice.jsx, frontend/src/page/ReceivedInvoice.jsx
Listens for storage update events and increments the refresh trigger to fetch updated invoices.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to bb2f3

The backup flow can report successful imports for malformed invoice payloads or noncanonical identifiers that may not be retrievable, creating a concrete correctness risk; the new backup controls and errors also bypass required localization. Merge should wait for these bounded issues to be addressed.

Poem

A rabbit packs invoices neat,
Into a JSON file complete.
The backup waits in Settings bright,
Then refreshes lists with gentle light.
Safe records hop back into sight.

Inline comments:
In `@frontend/src/components/InvoiceBackupSettings.jsx`:
- Line 45: Update the styling utilities in the InvoiceBackupSettings component,
including the panel container and the referenced lines, to use the semantic
Tailwind tokens defined in index.css instead of palette-specific classes.
Replace background, text, border, and primary-action color utilities with the
appropriate bg-card, text-foreground, text-muted-foreground, border-border,
bg-primary, and text-primary-foreground tokens while preserving the existing
layout and spacing classes.

In `@frontend/src/services/invoiceStorage/invoiceBackup.js`:
- Around line 66-70: Update the record validation in the invoice backup import
flow to validate the required invoice payload fields, not just that record.data
is an object. Ensure empty or malformed payloads are rejected before merging,
while valid invoice records continue through the existing restore path.
- Line 103: Externalize all newly added user-visible backup-flow strings through
the existing i18n resource keys: move validation and import errors in
frontend/src/services/invoiceStorage/invoiceBackup.js lines 103-103, replace
toast messages and backup control text in
frontend/src/components/InvoiceBackupSettings.jsx lines 15-18, and replace the
section title and description in frontend/src/page/Settings.jsx lines 22-24.
- Around line 25-33: Update the invoice identifier validation logic around the
visible string and serialized bigint checks to accept only canonical decimal
representations: reject leading-zero strings such as “0001” while allowing the
canonical zero form, and require numeric values to satisfy Number.isSafeInteger
rather than merely Number.isInteger. Apply the same canonical-string rule to
serialized bigint values so restored invoiceId and chainId values match on-chain
identifiers.

The requested validation and styling fixes are now pushed in commit 454a49a.

The i18n note is not applicable to this change because the frontend currently has no existing i18n/resource system to reuse, so I did not introduce a new localization dependency for this focused feature.

Hi @Atharva0506, I’ve provided my Discord ID and wallet address in the PR comments, but the onboarding GitHub Action keeps responding “Onboarding incomplete.” Could you please check the onboarding workflow? It seems to be repeatedly rejecting the information even though it is present in my comment.
