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.

Packages

@microsoft/fast-element

License: MIT npm version

The @microsoft/fast-element library is a lightweight means to easily build performant, memory-efficient, standards-compliant Web Components. FAST Elements work in every major browser and can be used in combination with any front-end framework or even without a framework. To get up and running with @microsoft/fast-element see the Getting Started guide.

@fluentui/web-components

License: MIT npm version

@fluentui/web-components is a library of Web Components based on the Fluent design language, built with @microsoft/fast-element.

The source for @fluentui/web-components is hosted in the Fluent UI monorepo.

Getting Started

We hope you're excited by the possibilities that FAST presents. But, you may be wondering where to start. Here are a few statements that describe various members of our community. We recommend that you pick the statement you most identify with and follow the links where they lead. You can always come back and explore another topic at any time.

Roadmap

Major features for the FAST project can be found in the roadmap.
