## Overview

This is a small Flask task manager. Browser users manage tasks through rendered pages, while API clients can create, read, update, and delete tasks through REST endpoints. Both interfaces use JSON-file persistence; a separate health route supports uptime checks. Route and storage behavior is evidenced in app.py; the README documents the API and health capabilities.

Main entry points: [`app.py`](https://github.com/nithish07-cmd/devops-task-manager/blob/main/app.py) (UI routes), [`templates/index.html`](https://github.com/nithish07-cmd/devops-task-manager/blob/main/templates/index.html) (Task page), [`data.json`](https://github.com/nithish07-cmd/devops-task-manager/blob/main/data.json) (Task records)
