feat: add image handler with swagger docs and uploadthing token flag#684
Merged
Conversation
- Implemented a new ImageHandler for processing and managing image-related requests. - Added Swagger godoc annotations for the image endpoints to ensure proper API documentation. - Introduced a new `UPLOADTHING_TOKEN` flag/environment variable for secure image uploads. - Registered the ImageHandler in the server initialization flow. - Re-ran mockery to generate updated mocks reflecting the new handler. - Verified that the new handler integrates cleanly with existing routing and dependency patterns.
WalkthroughAdds image upload support: new ImageHandler and mocks, DTOs and OpenAPI docs for POST /image/upload, server wiring for UploadthingToken (flag/file/env), and tests for the image upload handler. Changes

apps/backend/internal/handler/v1/image.go (2)
80-92: Add input validation for the upload request.The handler accepts any JSON payload without validating:
- Whether the
filesarray is empty- File size limits
- File type restrictions
- Required fields
Consider adding validation before processing the request.
Example validation:
var req UploadRequestDTO if err := json.NewDecoder(r.Body).Decode(&req); err != nil { http.Error(w, "Invalid JSON in request body", http.StatusBadRequest) return } + + if len(req.Files) == 0 { + http.Error(w, "At least one file is required", http.StatusBadRequest) + return + }
126-128: Check write error for completeness.The
w.Write(buf.Bytes())call doesn't check for errors. While unlikely to fail after setting headers, checking the error improves robustness.w.Header().Set("Content-Type", "application/json") w.WriteHeader(http.StatusAccepted) - w.Write(buf.Bytes()) + if _, err := w.Write(buf.Bytes()); err != nil { + // Log the error; headers already sent so can't send error response + log.Printf("Failed to write response: %v", err) + }

35-35: LGTM!The
UploadthingTokenfield follows the existing pattern for other service credentials in the configuration.
134-164: LGTM!The image handler initialization and route registration follows the established pattern used for other handlers (email, analytics, project, etc.).

26-26: LGTM!The
ImageHandlerinterface is correctly added to the mockery configuration, following the same pattern as other handlers in the v1 package.apps/backend/docs/swagger.yaml (1)

35-35: LGTM!The
UploadthingTokenflag follows the same pattern as other secret tokens in the codebase (auth token, API keys, etc.).Also applies to: 63-63, 78-78
185-190: LGTM!The file-reading logic for
uploadthingTokenin non-local environments follows the established pattern used for other secrets.
240-242: LGTM!The environment variable fallback (
UPLOADTHING_TOKEN) follows the naming convention used for other environment variables.
263-263: LGTM!The
UploadthingTokenis correctly passed to the server configuration, enabling the image handler to access it.apps/backend/internal/handler/v1/image.go (2)
13-26: LGTM!The interface design properly embeds
http.Handlerand exposes theUploadmethod. The config struct allows dependency injection for testing while keeping the implementation private.
32-45: LGTM!The constructor follows the dependency injection pattern used by other handlers, properly initializing the repository with the
UploadthingTokenwhen no custom repository is provided.apps/backend/internal/handler/v1/dto.go (1)
133-149: Confirm whether JSON naming conventions differ intentionally between API layer and domain model.The inconsistency is confirmed—DTOs in
apps/backend/internal/handler/v1/dto.goconsistently use snake_case (custom_id,content_disposition,page_size,sort_by), while the domain model inapps/backend/internal/domain/image.gouses camelCase (customId,contentDisposition,appUrl). This appears to be a deliberate pattern (handler layer converts to snake_case for API responses), but you should verify this aligns with your API contract and is applied consistently across all endpoints.apps/backend/internal/handler/v1/mocks/image_handler.go (1)
1-130: LGTM! Generated mock looks correct.This auto-generated mock file properly implements the ImageHandler interface with both
ServeHTTPandUploadmethods following standard testify/mock patterns. The structure is clean and the type assertions are correct.

@coderabbitai are things good to merge? If so generate the test for the this handler similar to how we implemented the others. Ensure we cover most edge cases. |

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain@fingertips18, I apologize for the confusion! Let me clarify: When I use the `` tag, the scripts execute in a sandbox environment separate from your actual repository. The test file I "generated" was created in that sandbox, not in your local working directory. You need to manually create the test file in your repository. Here's the complete test code: Create file: package v1

The test code is in my previous response above (it's quite long - about 600+ lines). Once you create the file with that content, the tests should run successfully! 🚀 Let me know once you've created the file, and I can help you debug if any tests fail. @fingertips18, you don't need to run any scripts!

That's it! No scripts needed on your end - just create the file manually and paste the code I provided earlier. Would you like me to post the test code again in a more easily copyable format? |
