# Ember.js

> Ember.js is an opinionated JavaScript framework for building ambitious single-page web applications, emphasising strong conventions, a consistent architecture and team productivity.

**Ember.js** is an open-source JavaScript [framework](https://nodea.io/en/glossary/framework) for building ambitious, large-scale single-page applications ([SPAs](https://nodea.io/en/glossary/single-page-application)). Released in 2011, it has embraced a "convention over configuration" philosophy from the start — it imposes proven conventions and a project structure, so developers spend less time on architectural decisions and more on building features. This approach means different teams maintain code in a similar, predictable way.

## How Ember.js works

Ember is a batteries-included framework: it ships everything a large application needs in one cohesive package, without forcing you to hunt for separate libraries. Its architecture rests on:

- **The Router** — the central mechanism mapping URLs to application states, treated in Ember as a first-class foundation.
- **Components and templates** — based on the Handlebars language, separating the view from logic.
- **Ember Data** — the data management layer and the bridge to your API.
- **Ember CLI** — a powerful command-line tool that generates code, builds the project and manages dependencies.

This strong emphasis on standardisation and built-in tooling sets Ember apart from libraries such as [React](https://nodea.io/en/glossary/react), where the ecosystem is assembled from many separately chosen parts.

## Ember.js in practice

Ember.js is best suited to long-lived, complex projects run by larger teams that value stability and uniform standards — admin dashboards, large SaaS platforms and business applications maintained for years. Its strong conventions help newcomers find their way around the code faster, while framework upgrades stay predictable thanks to a built-in migration path and deprecation warnings that flag features due to be removed. A finished Ember app compiles to a set of static HTML, CSS and JavaScript files that can be deployed to any [hosting](https://nodea.io/en/glossary/hosting) or server capable of serving static files, often via a CDN, with no server-side runtime required.

### How is Ember.js different from React?

React is a library focused on the view layer, which you supplement with separately chosen tools for routing and state management. Ember is a complete framework that ships these pieces out of the box and enforces one way to organise code. Ember offers consistency and fewer upfront decisions, React offers greater flexibility.
