How does component-check compare Angular and React component syntax?

It shows side-by-side code: Angular 1 uses directives with dependency injection, while React uses JSX and functional components. For example, Angular 2 employs class-based annotations, whereas React with Redux separates smart and dumb components.

Is component-check still relevant with today's framework updates?

The core concepts of component architecture remain useful, but many examples are dated, such as Angular 2 in beta. It's best for historical context or understanding fundamental differences rather than current best practices.

How to run the component-check examples on my machine?

Clone the repository, run npm install in each framework's directory, and use npm start to launch the dev server. Be aware of Node version issues, as noted in the README for Node v6.

What are the main differences between Cycle.js and Redux in component-check?

Cycle.js uses reactive streams and a functional approach with observables, while Redux with React employs a centralized store and reducer pattern. The examples highlight how each handles state changes and event-driven updates.

Can I learn CSS Modules integration from component-check?

Yes, it demonstrates CSS Modules with webpack across all frameworks, showing how to scope styles in Angular, Ember, React, and Cycle.js. However, the author cautions that it's for research and may not be ideal for production.

How does Ember handle components compared to Angular in this project?

Ember uses Handlebars templates and a convention-based system, requiring manual template registration with webpack, while Angular uses directives or class annotations. The README notes that Ember's angle-bracket components weren't available at the time.

component-check — JavaScript Component Framework Study

What is component-check?

Component-check is a comparative research project that demonstrates how to build components across multiple JavaScript frameworks. It provides side-by-side implementations of the same UI components in Angular 1, Angular 2, Ember, Cycle.js, and React with Redux, highlighting differences in syntax, tooling, and architectural patterns. The project helps developers understand framework trade-offs by showing concrete code examples from static to interactive components.

Target Audience

Frontend developers evaluating JavaScript frameworks for component-based architecture, or developers looking to understand differences between Angular, Ember, React, and Cycle.js through practical examples.

Value Proposition

It offers a neutral, code-first comparison of frameworks using consistent tooling (webpack, Babel, CSS Modules), making differences clear without bias. Developers get hands-on examples that go beyond documentation, showing real implementation patterns.

Overview

A quick introduction to exploring how components can be created in several frameworks.

Use Cases

Best For

Comparing component syntax across Angular, Ember, React, and Cycle.js
Understanding state management patterns in different frameworks
Learning how to integrate webpack and Babel with various frameworks
Evaluating framework choices for a new component-based project
Seeing practical examples of JSX and CSS Modules in different ecosystems
Studying how frameworks handle interactive and composable components

Not Ideal For

Teams building production apps with current framework versions (e.g., Angular 2+ or modern Ember)
Developers wanting plug-and-play examples without custom webpack and Babel configuration
Projects requiring full-stack guidance or deep framework tutorials beyond component basics
Environments needing guaranteed long-term maintenance or updates

Pros & Cons

Pros

Side-by-Side Framework Comparison

Provides identical component implementations in five frameworks (Angular 1, Angular 2, Ember, Cycle.js, React with Redux), enabling direct syntax and architectural analysis without vendor bias.

Progressive Complexity Examples

Builds components from static to interactive, demonstrating state management, event handling, and composition patterns in each framework, which aids in understanding trade-offs.

Consistent Modern Tooling

Uses webpack, Babel, and CSS Modules uniformly across all examples, ensuring a fair comparison and teaching how to integrate these tools with different ecosystems.

Hands-On Code-First Approach

Focuses on practical code examples rather than theory, helping developers see real implementation differences and learn through experimentation.

Cons

Outdated Framework Versions

Relies on old releases like Angular 2 alpha and pre-angle-bracket Ember, making examples less relevant for modern development, as admitted in the README notes.

Complex and Non-Standard Setup

Requires intricate webpack configurations and custom shims (e.g., for Ember without npm support), deviating from official tooling and increasing setup overhead.

Limited Scope and Maintenance

As a research project, it only covers component creation superficially, lacks updates for framework changes, and has known issues like Node v6 compatibility problems.
