Theme Framework How the LeaseLeads theme frontend works

Core Concepts

The JavaScript framework — the instance model, composition, loading, and why each works as it does.

The machinery under every component. These pages lean on why and how to use, not line-by-line mechanics — the load-bearing decisions are called out inline as Why it works this way notes.

  1. Instantiable & the instance model — the base every behaviour extends.
  2. The lifecycle — boot → afterBoot → init, and what belongs in each.
  3. Traits — how a component composes many capabilities at once.
  4. The Globals registry — the runtime registry and its external API.
  5. The AssetLoader pipeline — how a selector becomes a loaded, running component.
  6. Two-phase loading — Crucial, Deferred, and the performance story.
  7. Sub-components & HasX — how a host discovers and drives what's inside it.
