## Overview

This is a small Express to-do list: users view the list, add or delete items, and open and update individual items. The app keeps items in a process-local array and renders separate list and edit templates. The sampled source establishes these runtime relationships; deployment and delivery configuration in the tree is outside the product workflow shown here.

Main entry points: [`app.js`](https://github.com/londheshubham153/node-todo-cicd/blob/master/app.js) (Express app), [`views/todo.ejs`](https://github.com/londheshubham153/node-todo-cicd/blob/master/views/todo.ejs) (List template), [`views/edititem.ejs`](https://github.com/londheshubham153/node-todo-cicd/blob/master/views/edititem.ejs) (Edit template)
