Capstone Day 4: Polishing the To-Do App : Filtering, Pagination & Full Documentation

Day 4 — Making It Production Ready The API works. Now let's make it excellent. Today I added priority levels, filtering, pagination and full Swagger documentation. New Features Priority Levels Tasks now have 3 priority levels: low medium high Filtering GET /tasks?priority=high -> only high priority tasks GET /tasks?completed=false -> only incomplete tasks GET /tasks?priority=high&completed=false -> combined! Pagination GET /tasks?page=1&limit=5 -> first 5 tasks Response includes metadata: { "metadata" : { "total" : 10 , "page" : 1 , "limit" : 5 , "totalPages" : 2 }, "data" : [ ... ] } Full Swagger Documentation Every endpoint tagged, summarized and described. Available at /docs — zero extra work needed. Postman Tests Filter by priority Filter incomplete tasks Swagger docs What the Final API Looks Like Method Endpoint Auth Description GET / No API info GET /status No Health check POST /auth/signup No Register POST /auth/login No Login GET /tasks Yes Get tasks POST /tasks Yes Create task
