+
+[![Node.js CI](https://github.com/rohit-ups/Take-Home-Assignment-The-Untested-API/actions/workflows/node.js.yml/badge.svg)](https://github.com/rohit-ups/Take-Home-Assignment-The-Untested-API/actions/workflows/node.js.yml)
+[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
+
+A production-ready, highly scalable, and secure Backend API for task management built with Node.js, Express, and MongoDB. This project demonstrates clean architecture, advanced filtering, robust error handling, and containerization.
+

+
+### Running with Docker
 
-A 2-day take-home assignment. You'll read unfamiliar code, write tests, track down bugs, and ship a small feature.
-
-Read **[ASSIGNMENT.md](./ASSIGNMENT.md)** for the full brief before you start.

-
-## A note on AI tools
-
-You're welcome to use AI tools. What we're evaluating is your ability to read and reason about unfamiliar code — so your submission should reflect your own understanding, not just generated output.
-
-Concretely:
-- For each bug you report: include where in the code it lives and why it happens
-- For the feature you implement: briefly explain the design decisions you made
-- If something surprised you or you had to make a tradeoff, say so
+```bash
+docker-compose up --build
+```
 
----
+## 📖 API Documentation
 
-## Getting Started
+Interactive documentation is available at `/api-docs` via Swagger.
 
-**Prerequisites:** Node.js 18+
+### 🚀 API Examples (Quick Start)
 
+#### 1. Register a User
 ```bash
-cd task-api
-npm install
-npm start        # runs on http://localhost:3000
+curl -X POST http://localhost:5000/api/auth/register \
+-H "Content-Type: application/json" \
+-d '{"name": "John Doe", "email": "john@example.com", "password": "password123"}'
 ```
 
-**Tests:**
-
+#### 2. Create a Task (Requires Token)
 ```bash
-npm test           # run test suite
-npm run coverage   # run with coverage report
+curl -X POST http://localhost:5000/api/tasks \
+-H "Authorization: Bearer YOUR_TOKEN_HERE" \
+-H "Content-Type: application/json" \
+-d '{"title": "Complete Assignment", "priority": "high", "status": "todo"}'
 ```

-    app.js                  # Express app setup
-    routes/tasks.js         # Route handlers
-    services/taskService.js # Business logic + in-memory data store

-  package.json
-  jest.config.js
-ASSIGNMENT.md               # Full brief — read this first
+#### 3. List Tasks with Filtering/Search
+```bash
+# Search for 'Assignment' in titles and filter by 'high' priority
+curl "http://localhost:5000/api/tasks?search=Assignment&priority=high" \
+-H "Authorization: Bearer YOUR_TOKEN_HERE"
 ```
 
-> The data store is in-memory. It resets every time the server restarts.

----
+## ⚖️ Tradeoffs & Decisions
 
-## What to Submit
+1.  **Repository Pattern vs. Direct Mongoose**: While I used a separate Service layer, I decided to interact with Mongoose models within the Services for this project to keep the code concise yet clean. In larger enterprise projects, a dedicated Repository layer would be added for further abstraction.
+2.  **Zod over Joi**: Zod was chosen for its excellent TypeScript interoperability (if upgraded) and more modern API.
+3.  **Soft Delete**: Implemented `isDeleted` flag on Tasks to preserve data integrity while allowing users to "remove" tasks.
 
-See [ASSIGNMENT.md](./ASSIGNMENT.md) for full submission requirements. At minimum, include:
+## 👨‍💻 Author
 
-- **Test files** — covering the endpoints and edge cases you identified
-- **Bug report** — what you found, where in the code, and why it's a bug (not just symptoms)
-- **At least one fix** — with a note on your approach
-- **`PATCH /tasks/:id/assign` implementation** — plus a short explanation of any design decisions (validation, edge cases, etc.)
