Walkthrough

The pull request modifies the purchase service in src/services/purchaseService.ts, introducing a new helper function handleItemPrices to improve the handling of vendor purchases. The changes focus on modularizing the logic for processing item prices during a purchase transaction. A new inventoryChanges object is initialized to track inventory modifications, and the handleItemPrices function is designed to encapsulate the complex logic of updating inventory based on item prices. The return type of the handleSlotPurchase function has been updated to align with other purchase handling functions, suggesting a standardization of response structures across the purchase-related methods.

Assessment against linked issues

Objective	Addressed	Explanation
Handle ItemPrices for server-side vendor purchases [#796]	✅
Correctly subtract special currencies (e.g., Steel Essence)	✅

The changes directly address the issue by introducing a dedicated handleItemPrices function that appears designed to process item prices and manage inventory changes, which should resolve the problem of not subtracting special currencies during vendor purchases.

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Generate unit testing code for this file.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai generate unit testing code for this file.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
- @coderabbitai read src/utils.ts and generate unit testing code.

50-50: Good refactoring of inventory changes tracking!

The introduction of a separate inventoryChanges object and its combination with the purchase response improves code organization and maintainability.

Also applies to: 77-77

278-278: LGTM! Good standardization of return types.

The change to Promise<IPurchaseResponse> aligns the function's return type with other purchase handling functions, improving consistency across the codebase.

61-68: Verify potential duplicate item price handling.

The code processes item prices twice in different sections:

For vendor manifest items (lines 61-68)

For ExportVendors items (lines 130-135)

This could lead to duplicate processing if both conditions are met. Please verify that these sections are mutually exclusive.

Also applies to: 130-135

🛠️ Refactor suggestion

Add error handling for inventory operations.

While the function nicely modularizes item price handling, it lacks error handling for inventory operations. Consider:

Validating input parameters
Adding try-catch blocks
Implementing rollback logic if an operation fails

 const handleItemPrices = async (
     accountId: string,
     itemPrices: IMiscItem[],
     purchaseQuantity: number,
     inventoryChanges: IInventoryChanges
 ): Promise<void> => {
+    if (!accountId || !itemPrices || !Array.isArray(itemPrices)) {
+        throw new Error('Invalid input parameters');
+    }
+
+    try {
         const inventory = await getInventory(accountId);
+        const originalState = JSON.parse(JSON.stringify(inventory));
+
         for (const item of itemPrices) {
             const invItem: IMiscItem = {
                 ItemType: item.ItemType,
                 ItemCount: item.ItemCount * purchaseQuantity * -1
             };

             addMiscItems(inventory, [invItem]);

             inventoryChanges.MiscItems ??= [];
             const change = (inventoryChanges.MiscItems as IMiscItem[]).find(x => x.ItemType == item.ItemType);
             if (change) {
                 change.ItemCount += invItem.ItemCount;
             } else {
                 (inventoryChanges.MiscItems as IMiscItem[]).push(invItem);
             }
         }
         await inventory.save();
+    } catch (error) {
+        logger.error('Failed to process item prices:', error);
+        throw new Error('Failed to process item prices');
+    }
 };
