Introduction
FAST is dedicated to providing support for native Web Components and modern Web Standards, and it's designed to help you efficiently tackle some of the most common challenges in website and application design and development.
TL;DR
- Create reusable UI components with
@microsoft/fast-element, all based on W3C Web Component standards. - Integrate FAST Web Components with any library, framework, or build system. You can adopt incrementally without re-writing your existing systems.
For an in-depth explanation of FAST see our docs introduction.
