Feat/getall

[nafiuishaaq]

✅ Completed

Implemented GET /api/projects with:

• public access (no authentication required)
• filtering by category
• full-text search on title and description
• pagination via page and limit
• default sorting by createdAt descending
• only active public campaigns returned (status: 'active' and isActive: true)
• pagination metadata: total, page, limit, totalPages

Files updated

• project.controller.js
• project.routes.js
• Project.model.js
• project.routes.test.js

Validation

• npx jest project.routes.test.js --runInBand
• Result: 7 passed

If you want, I can also add a dedicated endpoint test for search + category with actual returned payload shape.

Made changes.

Closes #74
