Hello world

Why choose Aurelia?

Aurelia emerges as a beacon of innovation and power in front-end development in a sea of frameworks. Here's why Aurelia might be the perfect choice for your next project:

  • All-in-One Ecosystem: Aurelia is your Swiss Army knife, offering everything from dependency injection to routing, eliminating the need to juggle multiple libraries. Its ecosystem extends to plugins for internationalization, validation, and more, supported by tools like a CLI and a VS Code plugin for seamless development. And with Aurelia, flexibility is key; you can customize every aspect, including the templating/binding engine.

  • Unparalleled Performance: Speed and efficiency are in Aurelia's DNA. It consistently outperforms competitors in benchmarks thanks to its sophisticated batched rendering and efficient memory usage.

  • Data-Binding Done Right: Aurelia harmonizes the safety of uni-directional data flow with data-binding productivity, ensuring both performance and ease of development.

  • Stability in a Dynamic World: Since our 1.0 release in 2016, Aurelia has maintained API stability, innovating without breaking changes, a testament to our commitment to developer trust.

  • Adherence to High Standards: Aurelia is a paragon of standards compliance, focusing on modern JavaScript and Web Components without unnecessary abstractions.

  • Empowering Developers: Aurelia's philosophy is simple: empower developers with plain JavaScript/TypeScript and get out of the way. This results in cleaner, more maintainable code.

  • Ease of Learning and Use: Aurelia's design is intuitive and consistent, minimizing the learning curve and maximizing productivity with solid, simple conventions.

  • Seamless Integration: Aurelia plays well with others. Its adherence to web standards makes it a breeze to integrate with any third-party library or framework.

  • A Vibrant Open-Source Community: Embrace the open-source ethos with Aurelia, licensed under MIT, without restrictive clauses. Join a community that thrives on collaboration and innovation.

  • A Welcoming and Supportive Community: Our active core team and Discord server embody a culture of welcome and support, where every developer is a valued member of the Aurelia family.

Embracing a Boutique Ecosystem

While it's true that Aurelia's ecosystem and community might seem modest compared to some of its more populous counterparts, this perceived underdog status is, in fact, one of its greatest strengths. Aurelia represents a boutique choice in web frameworks, prioritizing quality over quantity and fostering a tight-knit, highly engaged community. This approach translates to a more focused, consistent, and dedicated development experience, both in terms of the framework itself and the support you receive from the community.

The Advantages of a Niche Community

  • Direct Impact: In a smaller community, each member's voice and contribution have a more significant impact. Developers have direct access to the core team, fostering a collaborative environment where feedback and contributions influence the framework's evolution.

  • Quality Over Quantity: Aurelia focuses on delivering a high-quality, refined development experience. This means that each plugin, library, and tool in the ecosystem has been carefully crafted and thoroughly vetted to meet high standards.

  • Nurturing Innovation: A smaller ecosystem doesn't mean limited capabilities. On the contrary, it often leads to innovative solutions and creative problem-solving, as developers are encouraged to think outside the box.

  • Stronger Connections: A smaller community fosters closer relationships, leading to more meaningful interactions, collaborations, and a sense of belonging. This environment is conducive to a supportive and helpful atmosphere where developers at all levels can thrive.

Why Size Isn't Everything

The size of a community or ecosystem should not be the sole criterion for its effectiveness. In many cases, the quality of interactions, the dedication of its members, and the framework's alignment with your project's needs are far more critical factors. Aurelia's commitment to standards, modern best practices, and empowering approach offers a unique and rewarding development experience that stands on its own merits. Aurelia isn't trying to reinvent the wheel or make your life a misery by changing its API with every major release.

The Power of Conventional DOM Manipulation: why Aurelia doesn't have a Virtual DOM

In a landscape where Virtual DOM is often touted as a necessity, Aurelia confidently takes a different path. Aurelia's choice not to use a Virtual DOM is a deliberate and strategic decision grounded in a philosophy that prioritizes efficiency, simplicity, and alignment with web standards.

Understanding the Conventional DOM Approach

  • Directness and Efficiency: Aurelia interacts directly and efficiently with the DOM. By avoiding the overhead of a Virtual DOM, Aurelia ensures faster rendering and updates, leading to a smoother user experience.

  • Simplicity and Predictability: Without the abstraction layer of a Virtual DOM, Aurelia offers a more straightforward and predictable development experience. Developers work closer to the web platform, leveraging native browser capabilities for DOM manipulation.

  • Optimal Performance: Aurelia's approach to DOM updates is highly optimized. It intelligently manages DOM changes, ensuring minimal performance overhead. This results in applications that are not only fast but also more resource-efficient. Let's say Aurelia isn't going to drain your phone or Macbook Pro battery.

The Benefits of Conventional DOM in Aurelia

  • Aligned with Web Standards: Aurelia's commitment to standards means that it leverages the native capabilities of modern browsers, ensuring compatibility and future-proofing your applications. If the browser can do it, Aurelia won't try one-upping it by rolling its own implementation.

  • Less Complexity, More Control: By avoiding a Virtual DOM, Aurelia reduces the complexity of your application's architecture. This direct approach gives developers more control and understanding of how their application interacts with the browser.

  • Tailored for Modern Web Development: Aurelia is designed to meet the needs of modern web applications. Its efficient, standards-based approach is perfectly suited for today's dynamic, interactive web experiences.

The decision to not use a Virtual DOM is a reflection of Aurelia's overarching philosophy: to provide a powerful, efficient, and straightforward framework that stays true to the nature of the web. This approach encourages developers to build applications that are both performant and maintainable, leveraging the full potential of the web platform.
