Open-source Backend Contribution
CropChain · Aperture 2.0
An open-source contribution focused on validating backend requests and testing API behavior in the CropChain project.
Context & approach
The problem, then the system.
Approach
Added Joi validation schemas and centralized request-validation middleware, then wrote Jest and Supertest integration tests for API behavior and error handling.
System map
How the pieces connect.
This contribution focused on a backend request path: validate input centrally, then exercise API success and error behavior with integration tests.

Engineering notes
Decisions that shape the experience.
Validate requests at the boundary
Joi schemas define accepted request data before it reaches the route logic.
Share validation behavior
Centralized Express middleware applies request validation consistently across the protected route.
Test behavior through HTTP
Jest and Supertest integration tests cover API responses and error handling.
