Build a Vanilla JavaScript Todo App with State-Driven UI

DEV Community •

Amirhossein LN released a lightweight Todo app built entirely in JavaScript. The project eschews frameworks, focusing instead on pure DOM manipulation and a state-driven architecture. By deriving the UI from a single source of truth, the code stays predictable and easier to debug for developers learning best practices today daily.

Deploying the app to github.io lets users interact with it directly in the browser, while the accompanying GitHub repository offers a clean, commented codebase. This hands‑on example demonstrates how to manage state, render lists, and handle events without external libraries—an ideal teaching tool for newcomers to build modern web applications.

By avoiding frameworks, the project highlights core JavaScript concepts that underpin modern libraries like React or Vue. Developers can trace how state changes trigger re‑renders, gaining insight into virtual DOM mechanics. Next steps include adding persistence with localStorage or expanding to a full CRUD interface for future scalable applications today.
