Walkthrough

The pull request modifies the invoice-view.svelte component to enhance the transaction signing and approval processes. A new state variable isSigningTransaction is introduced to indicate when a transaction is being signed. This variable is utilized in both the approve and payTheRequest functions to manage the UI state during these processes. Additionally, the button enabling logic is updated to improve user experience by preventing actions during ongoing transactions, along with enhanced error handling for clearer user notifications.

Line range hint 398-433: Add explicit error handling for approval failures

While the function has a try-catch block, it doesn't provide specific error handling for common approval scenarios (e.g., user rejection, network issues). This could lead to a poor user experience when transactions fail.

Consider adding specific error handling:

 } catch (err) {
   console.error("Something went wrong while approving ERC20: ", err);
+  if (String(err).includes("ACTION_REJECTED") || String(err).includes("User rejected")) {
+    toast.error("Approval cancelled", {
+      description: "You rejected the transaction",
+    });
+  } else {
+    toast.error("Approval failed", {
+      description: err instanceof Error ? err.message : String(err),
+    });
+  }
+  // Reset approval status
+  approved = false;
 } finally {

Learning: In `packages/invoice-dashboard/src/lib/dashboard/invoice-view.svelte`, mapping payment network IDs to their respective approval functions in the `checkApproval` function is acceptable and can improve readability and maintainability.

Learning: In the `checkApproval` function of `packages/invoice-dashboard/src/lib/dashboard/invoice-view.svelte` (TypeScript/Svelte code), remember that the `ETH_FEE_PROXY_CONTRACT` payment network ID does not require approval because Ether payments do not need ERC20 approvals.

398-398: Consider potential race conditions with transaction signing state

The isSigningTransaction flag is used correctly to prevent multiple simultaneous transactions. However, there could be a race condition if multiple transactions are attempted in quick succession, as the flag might be reset to false before the previous transaction is fully processed.

Consider using a more robust state management solution, such as:

  1. Using a transaction queue
  2. Implementing a mutex-like pattern
  3. Adding a debounce mechanism to the payment buttons

Also applies to: 433-433
