Build UIs with HLive, the server-side virtual-DOM framework for Go (github.com/SamHennessy/hlive). Use when working with HLive code — the `l "github.com/SamHennessy/hlive"` import, builders like l.T / l.C / l.CM, NewPage / NewPageServer, On(...) event bindings, l.Box reactive values, or questions about HLive components, rendering, the SSR-vs-WebSocket lifecycle, and tree-diff gotchas.
Build HLive page markup with the hhtml package (github.com/SamHennessy/hlive/hhtml) — typed, autocompleting Go builders for HTML5 tags and attributes (Div, Button, A, Input, Class, Href, ...). Use when writing or editing HLive page/component markup, when you see the `. "github.com/SamHennessy/hlive/hhtml"` dot-import, or when choosing between hhtml builders and the raw l.T/l.C primitives.
Structure a real multi-page HLive application in Go — the main.go entry point and net/http routing, a page/ package of page factories, reusable component functions, static asset serving, and build/run setup. Use when starting a new HLive project, adding a page or route, organizing components across files, or deciding where state and assets live (beyond the single-file _example/ demos).
Write browser tests for HLive pages using the hlivetest package (github.com/SamHennessy/hlive/hlivetest) and Playwright. Use when testing HLive UI behavior end-to-end — spinning up a test server, driving a real browser (Click/ClickAndWait, TextContent, GetAttribute), and asserting with hlivetest.Diff. Use when an HLive task mentions tests, Playwright, or verifying interactive behavior.
Use the hlivekit toolkit (github.com/SamHennessy/hlive/hlivekit) for common HLive needs — dynamic lists of components (ComponentList / hlivekit.List), giving an input focus, running server logic after a browser diff applies (OnDiffApply), real-time fan-out updates (PubSub), element-visibility events, scroll/redirect helpers, and preempt-disable-on-click. Use when an HLive task involves any of these patterns or imports the hlivekit package.
