A library for building standards-compliant Web Components and adaptive UI systems for modern web applications.
FAST is an adaptive interface system for building modern web experiences using native Web Components. It provides tools like `@microsoft/fast-element` for creating standards-compliant, reusable UI components and `@fluentui/web-components` for pre-built components based on Fluent design. It solves the challenge of creating interoperable, high-performance components that work across frameworks and browsers.
Frontend developers and teams building web applications who need reusable, framework-agnostic UI components or want to adopt Web Components incrementally in their projects.
Developers choose FAST for its strong commitment to web standards, allowing them to build components that integrate seamlessly with any framework while avoiding vendor lock-in. Its performance focus and Microsoft-backed Fluent design components provide a reliable foundation for enterprise-scale applications.
The adaptive interface system for modern web experiences.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
FAST builds on W3C Web Component standards, ensuring components are interoperable and future-proof across all major browsers, as emphasized in the README.
Components work with any library or framework, enabling incremental adoption without rewriting existing systems, a key feature highlighted in the introduction.
Includes @fluentui/web-components based on Microsoft's Fluent design, providing a reliable, scalable UI foundation for large applications.
Designed for high performance and memory efficiency, with components that are lightweight and compatible across browsers, as stated in the key features.
The Web Components ecosystem around FAST has fewer community plugins and tools compared to mainstream frameworks like React or Angular, which can slow development.
Creating custom components requires mastering @microsoft/fast-element, which might be complex for developers unfamiliar with Web Component intricacies.
Documentation is split between FAST and FluentUI sources, as noted in the README, making it harder to find cohesive information quickly.
