Web components - overview

Web Components are at the very heart of our strategy - which is based on native browsers and a standards-based component model.

This eliminates a number of problems, such as deciding between Angular, React & Vue, dealing with version clashes & upgrades, or needing to onboard web-framework specialists.

Our Web Components are built on top of Microsoft FAST, which is a lightweight abstraction that enables you to build performant, memory-efficient, standards-compliant Web Components.

Our Genesis packages are scoped to @genesislcap. These consist of:

  • @genesislcap/foundation-ui: Base components
  • @genesislcap/foundation-zero: The zero design-system variant
  • @genesislcap/foundation-utils: Utilities
  • @genesislcap/foundation-comms: Comms system
  • ...etc
