Walkthrough

The pull request focuses on enhancing type safety and clarity across multiple TypeScript files in the project. The changes primarily involve updating function signatures to explicitly define return types, which helps improve code readability and reduces potential type-related errors. These modifications span various services, controllers, helpers, and utility files, including inventoryService.ts, loginService.ts, configService.ts, and others.

The modifications do not alter the core logic or functionality of the existing code but instead provide more precise type annotations. This includes specifying return types for asynchronous functions, clarifying whether functions return a value or perform side effects, and ensuring that function signatures accurately represent their intended behavior. The changes reflect a systematic approach to strengthening the type system and improving overall code quality.

Thank you for using CodeRabbit. We offer it for free to the OSS community and would appreciate your support in helping us grow. If you find it useful, would you consider giving us a shout-out on your favorite social media?

Actionable comments posted: 1

🧹 Nitpick comments (16)

src/controllers/api/getFriendsController.ts (1)
3-3: Consider aligning the content type with the actual response format.
Currently, the header specifies "text/html", but the response data is a JSON object ({}\n). For clarity and correctness, consider setting the content type to "application/json" if the payload is intended to be interpreted as JSON.
"Content-Type": "text/html",
+ "Content-Type": "application/json",
src/services/loadoutService.ts (1)

5-5: Use a more descriptive error or handle gracefully.
When loadout is not found, the function throws a generic error. Consider using a custom error class or a dedicated error type for clearer error handling and potential logging improvements.
src/services/recipeService.ts (1)
7-7: Optional improvement: define a dedicated interface.

Returning an inline type clarifies the function’s Promise result; however, creating a dedicated interface (e.g., IStartRecipeResult) would further improve readability and consistency.
-export const startRecipe = async (recipeName: string, accountId: string): Promise<{ RecipeId: { $oid?: string } }> => {
+interface IStartRecipeResult {
+  RecipeId: {
+    $oid?: string;
+  };
+}
+
+export const startRecipe = async (recipeName: string, accountId: string): Promise<IStartRecipeResult> => {
src/services/purchaseService.ts (2)

28-28: Explicit return type improves readability.

By specifying : string, future contributors clearly see that this function must return a string. Make sure to handle any unexpected cases (e.g., no slash in storeItem) to avoid runtime errors.

34-34: Return type clarity for getStoreItemTypesCategory.

Similar to the above change, explicitly returning a string enhances type safety. Consider validating or sanitizing the substring result in case typesItem doesn't follow the expected "/Types" structure.

src/services/inventoryService.ts (11)

369-369: Add a graceful error check for invalid sentinelName.

If sentinelName isn't present in ExportSentinels, undefined behavior may occur. Consider throwing an error or returning early.

402-406: Validate array index after pushing.

If sentinelIndex is less than 1, accessing sentinelIndex - 1 might be out of bounds. A quick boundary check prevents runtime errors.

460-464: Add a safety check on suitIndex boundary.

If suitIndex happens to be 0 or negative, accessing [suitIndex - 1] could cause an error. A simple check ensures greater stability.

467-472: Validate slot parameters.

Consider validating slotAmount and extraAmount for negative or unexpected values to avoid inconsistent slot states.

666-666: Consider returning the updated items.

addMiscItems mutates the inventory in place. Returning the new or updated items could improve testability and clarity.

681-684: Extract shared push-or-increment logic.

addShipDecorations closely resembles other add methods. A shared helper function could reduce duplication and ease updates.

699-699: Refactor repeated array update patterns.

addConsumables uses the same push-or-increment pattern found in other methods. Consider extracting a common utility function for maintainability.

714-714: Promote DRY by unifying array updates.

addRecipes just like addConsumables, addMiscItems, etc., could reuse a utility function to limit code repetition.

729-729: Centralize repeated push-or-increment logic.

addMods duplicates array-updating patterns. A single helper would streamline future maintenance.

746-746: Apply a unified approach to array updates.

addFusionTreasures also does item lookups and increments. A consolidated helper can reduce code duplication.

807-807: Consider returning the updated missions.

addMissionComplete mutates inventory.Missions but doesn't return anything. Returning the updated missions could help with testing or chaining in other parts of the code.

🔇 Additional comments (15)

src/services/loadoutService.ts (2)

3-3: Ensure that ILoadoutDatabase matches the shape of loadout.toJSON().
While importing ILoadoutDatabase improves type clarity, verify that all fields returned by loadout.toJSON() align with the interface. Mismatches may cause runtime errors or type confusion.

13-13: Validate serialization before returning.
Confirm that any additional fields or sensitive data are not inadvertently exposed by toJSON(). You could sanitize or omit certain fields before returning if necessary.

src/helpers/purchaseHelpers.ts (1)

8-8: Explicit return type improves clarity.
Specifying SlotPurchaseName clarifies the function's output and helps prevent incorrect usage. This change aligns well with the type-safe objective of this PR.

src/middleware/middleware.ts (1)

4-4: Function signature and behavior are consistent.
Defining the function’s return type as void clarifies that it ends the request by sending a 404 response without returning additional data. This matches Express middleware usage.

src/helpers/stringHelpers.ts (1)

20-20: Explicit return type enhances clarity.

By specifying a return type of number, you make it clear to consumers that the function can potentially return -1 when the searchWord is not found, or a valid index otherwise. This aligns well with JavaScript’s String.indexOf() convention.

src/services/configService.ts (1)

59-59: Clearer return type benefits maintainability.

By declaring a Promise<void> return type, you convey that the function’s asynchronous operation completes without returning a value, making it clearer for future maintainers.

src/services/loginService.ts (2)

37-37: Explicit return type is a great addition.

Declaring Promise<Types.ObjectId> makes it clear to consumers that this function resolves to the saved document's _id. This is a good step towards ensuring type safety.

43-43: Void return type is consistent and appropriate.

By explicitly returning Promise<void>, this clarifies that no value is returned while still emphasizing that the function is asynchronous.

src/utils/logger.ts (1)

106-106: Clear indication of no return value.

Declaring the return type as void removes ambiguity and signals to maintainers that this function doesn't produce a result. Good job on improving type clarity.

src/services/missionInventoryUpdateService.ts (1)

187-187: Explicit return type ensures thorough type checks.

Specifying void here aligns with the rest of the code that updates the InventoryChanges and also clarifies the function's contract. This helps avoid confusion for anyone expecting a returned value.

src/models/inventoryModels/inventoryModel.ts (1)

329-329: Consider verifying that v.$oid is present before returning its string.

If there's a possibility that the object is null or lacks the $oid property, a runtime error may be thrown.

src/services/inventoryService.ts (4)

50-50: Good practice to specify Promise<void>.

Declaring an explicit Promise<void> clarifies that the function is asynchronous with no returned value.

760-763: Great clarity on async return type.

Specifying Promise<void> for updateChallengeProgress is consistent with the broader code style and clarifies the function’s purpose.

775-775: No issues detected here.

addSeasonalChallengeHistory follows the same pattern as other helper methods. The logic looks good.

789-792: ⚠️ Potential issue

Fix the .markModified path.

You're modifying Progress, but the code references .ItemCount. Update it to reference .Progress:

- inventory.markModified(`ChallengeProgress.${itemIndex}.ItemCount`);
+ inventory.markModified(`ChallengeProgress.${itemIndex}.Progress`);

Likely invalid or redundant comment.

Based on the search results, I can see that:

The toMongoDate function is used in several places to convert dates for MongoDB storage
The function is used in critical paths like inventory models and guild controllers
There's no existing date validation in the codebase

Given that this function is used in multiple important places and handles date conversions for database storage, adding validation is a good practice to prevent invalid data from being stored.

Add date validation to prevent invalid date storage

The suggestion to validate the date object is correct. Invalid dates could lead to incorrect data being stored in MongoDB, which could cause issues in data retrieval and processing. The proposed validation using isNaN(date.getTime()) is a standard and reliable way to check for invalid Date objects.

🔗 Analysis chain

Consider validating the date object.

While returning an IMongoDate improves type safety, ensure the passed date is valid. If date is invalid (NaN), the result may produce incorrect values. You could check for isNaN(date.getTime()) before constructing the IMongoDate.

 export const toMongoDate = (date: Date): IMongoDate => {
+  if (isNaN(date.getTime())) {
+    throw new Error("Invalid date provided.");
+  }
   return { $date: { $numberLong: date.getTime().toString() } };
 };

Let me verify the concern by checking how this function is used in the codebase and if there are any existing date validation mechanisms.

Let me try another search to find the interface definition and check how the function is used.

Let me check one more thing to see if there's any existing error handling for invalid dates.

🏁 Scripts executed

The following scripts were executed for the analysis:
