🧹 Nitpick comments (6)
.gitignore (1)
37-40: Addition is fine, but tweak formatting & pattern for completeness
.DS_Storeand.claude/are appropriate additions, yet a few polish points will keep the file tidy:
- Group
.DS_Storewith other OS-generated artefacts (e.g., directly after the existing.DS_Storecomment block, if present) for easier scanning.- The comment
# Claudehas an extra trailing space – remove it for consistency with the rest of the file.- To ignore both a directory and any file that might be called
.claude, list both patterns or drop the slash:-# Claude -.claude/ +# Claude +.claude +.claude/Very minor, but keeps the ignore rules predictable and consistent.
src/modules/messaging/dto/message.dto.ts (1)
4-6: Consider adding length validation to content field.While the string and non-empty validation is correct, consider adding
@MaxLength()decorator to prevent extremely long messages that could impact performance or storage.@IsString({ message: "Content must be a string" }) @IsNotEmpty({ message: "Content is required" }) + @MaxLength(5000, { message: "Content cannot exceed 5000 characters" }) content: string;src/modules/auth/dto/wallet-validation.dto.ts (1)
3-35: Stellar wallet validation is technically correct but has code duplication.The validation logic properly implements Stellar address format requirements:
- Correct 56-character length constraint
- Accurate regex pattern for Stellar addresses (G + 55 base32 characters)
- Clear error messages
However, consider refactoring to eliminate duplication between the two DTOs.
Create a base class or use composition to avoid duplicating wallet validation:
class BaseWalletDto { @IsString({ message: "Wallet address must be a string" }) @MinLength(56, { message: "Stellar wallet address must be 56 characters long" }) @MaxLength(56, { message: "Stellar wallet address must be 56 characters long" }) @Matches(/^G[A-Z2-7]{55}$/, { message: "Invalid Stellar wallet address format" }) walletAddress: string; } export class ValidateWalletFormatDto extends BaseWalletDto {} export class VerifyWalletDto extends BaseWalletDto { @IsString({ message: "Signature must be a string" }) signature: string; @IsString({ message: "Message must be a string" }) message: string; }src/shared/middleware/validation.middleware.ts (1)
44-49: Enhance error handling with proper logging.The generic error handling should include logging for debugging purposes while maintaining security by not exposing internal errors to clients.
- } catch { + } catch (error) { + console.error('Validation middleware error:', error); res.status(500).json({ success: false, error: "Internal server error during validation", }); }Apply similar changes to the other validation functions for consistency.
src/modules/organization/presentation/controllers/organization.controller.ts (2)
119-129: Simplify default value handling using DTO defaults.The
PaginationQueryDtoalready provides default values (page = 1,limit = 10), so manual fallbacks are unnecessary. The validation middleware should handle these defaults automatically.- const { page, limit, search } = req.query; - - const organizations = await this.getAllOrganizationsUseCase.execute({ - page: page || 1, - limit: limit || 10, - search, - }); + const { page, limit, search } = req.query; + + const organizations = await this.getAllOrganizationsUseCase.execute({ + page, + limit, + search, + });
134-136: Remove duplicate default value handling.Since the DTO provides defaults and they're already handled in the use case call, remove the duplicate fallback logic here.
pagination: { - page: page || 1, - limit: limit || 10, + page, + limit, total: organizations.length, },

🛠️ Refactor suggestion
Add regex pattern validation for Stellar wallet addresses.
The wallet address validation only checks length but missing format validation. Based on other wallet DTOs in the codebase, Stellar addresses should match the pattern /^G[A-Z2-7]{55}$/.

Parameter validation mismatch will cause failures.
The route uses :userId parameter but UuidParamsDto expects an id property. This mismatch will cause validation failures.
Create a dedicated DTO for this route or use a different approach:
// Option 1: Create UserIdParamsDto
export class UserIdParamsDto {
@IsUUID(4, { message: "User ID must be a valid UUID" })
userId: string;
}

Verify controller integration before deployment.
The route structure and validation middleware integration look excellent. However, the controller methods are currently commented out as placeholders. Ensure that proper controller implementations are added before deploying these routes to prevent 404 errors.

Wire up AuthController in v2 routes
The DTO validation is in place, but none of the routes actually invoke your controller logic—each handler is still commented out and only a 501‐stub exists. Before deploying, you need to import and attach the real (or fully implemented) AuthController methods in src/routes/v2/auth.routes.ts.
• File: src/routes/v2/auth.routes.ts (lines 17–57)
- Uncomment and add the controller after
validateDto(...), e.g.:import AuthController from "../../modules/auth/presentation/controllers/Auth.controller"; router.post( "/register", validateDto(RegisterDto), AuthController.register ); // …and so on for login, resendVerificationEmail, verifyEmail, validateWalletFormat, verifyWallet
• Ensure you replace or extend the stub in
src/modules/auth/presentation/controllers/Auth.controller.stub.ts
with your real service calls (right now it always returns 501).
• Run a quick smoke test against each route to confirm no 404s/501s remain.
🤖 Prompt for AI Agents
In src/routes/v2/auth.routes.ts between lines 17 and 57, the route handlers are
currently commented out and only DTO validation is active, resulting in 501
responses. To fix this, import AuthController from the appropriate path and
uncomment each route handler, attaching the corresponding AuthController method
after the validateDto call for each route. Also, update the stub controller in
src/modules/auth/presentation/controllers/Auth.controller.stub.ts to implement
real service logic instead of returning 501. Finally, test each route to ensure
they respond correctly without 404 or 501 errors.

In src/shared/middleware/validation.middleware.ts at line 22, the call to
plainToClass lacks transformation options that improve type safety and security.
Update the plainToClass invocation to include options that enable automatic type
conversion and exclude extraneous properties, ensuring only expected fields are
transformed and validated.

🛠️ Refactor suggestion
Configure transformation options and handle query parameter types properly.
Query parameters need special handling since they come as strings from Express. The transformation should include options to enable type conversion and exclude extraneous values.

In src/shared/middleware/validation.middleware.ts at line 60, the transformation
of req.query to the DTO class does not handle type conversion or exclude
extraneous values. Update the plainToClass call to include transformation
options that enable type conversion and exclude properties not defined in the
DTO class to properly handle query parameters as strings and ensure correct
validation.

🛠️ Refactor suggestion
Configure transformation options for route parameter validation.
Route parameters are always strings in Express, so enabling implicit conversion is crucial for proper type transformation.

+ const dto = plainToClass(dtoClass, req.params, {
+ enableImplicitConversion: true,
+ excludeExtraneousValues: true,

In src/shared/middleware/validation.middleware.ts at line 98, the plainToClass
function is used without transformation options, but since route parameters are
always strings in Express, you need to enable implicit type conversion. Fix this
by passing transformation options to plainToClass with {
enableImplicitConversion: true } to ensure proper type conversion of route
parameters.

📝 Changes description
This PR enhances input validation across the user, project, and organization modules by replacing the existing
express-validatorlogic with a DTO-based validation approach usingclass-validator. Each controller route now uses typed DTOs with proper@Is*decorators to validate and sanitize incoming data. This shift aligns the API layer with our Domain-Driven Design (DDD) architecture and ensures that all inputs are clean, consistent, and secure before any processing occurs. Controllers were updated to integrate this mechanism with robust error handling for invalid inputs. The refactor ensures long-term maintainability and improved input hygiene throughout the application.⏰ Time spent breakdown
