Our web component packages.

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.

The @microsoft/fast-ssr package contains a NodeJS solution for rendering FAST templates and components. While primarily intended for supporting server-side rendering (SSR) scenarios, it also allows FAST to be used as a general purpose HTML templating solution.

The @microsoft/fast-router package contains a history-based navigation and routing solution designed around Web Components. By using fast-router, you can create multi-page and full application experiences. The router works with any Web Components, but has special support for Web Components built on FAST.

@fluentui/web-components is a library of Web Components that composes @microsoft/fast-foundation. @fluentui/web-components makes use of different stylesheets and may include components that specifically support Microsoft's Fluent design language.

The Fluent UI Web Components are built on @microsoft/fast-element and @microsoft/fast-foundation. The source for @fluentui/web-components is hosted in the Fluent UI monorepo.
