These are industrial-grade components. Their design has benefited from the input of more than 100 web engineers at Yahoo!, and we’re working hard to make usage both clear and flexible. Each utility and widget in the library has been battle-hardened in the browsers of millions of users and in the aggregate this code provides the foundation for some of our most heavily trafficked applications, including the My Yahoo! customizable news portal. Each member of the library supports the full suite of A-grade Browsers within our Graded Browser Support scheme, providing a consistent cross-browser platform for developing richly interactive features. In short, these are the same utilities and widgets that power an increasingly broad spectrum of Yahoo! properties today; they are alive in our flagship products and at massive scale; we’re committed to this library’s growth and refinement because we’re committed to being more ambitious in the interactive idioms we create for Yahoo!’s 400 million users.
The creation and open-sourcing of the Yahoo! User Interface Library highlights two of our core convictions about the current state of the Web and the nature of front-end engineering:
We’re excited to share this work with you today as we join more publicly in the vibrant ecosystem of front-end engineering. The web has been reborn with ideation and experimentation during the past several years, and much of its buoyancy has been driven by the creative essence of this discipline’s membership. We hope in this library you find ideas and solutions that, in ways however small or humble, energize your participation in web’s current renaissance.
