feat(chat): production-ready visual redesign (0.0.3) by blove · Pull Request #157 · cacheplane/angular-agent-framework

blove · 2026-05-01T17:54:20Z

Summary

Coordinated rewrite of @ngaf/chat for production-grade visual quality. Three new layout modes (embedded/popup/sidebar), asymmetric message pattern (user bubble + assistant inline), shared chat-trace primitive driving tool calls/subagents/timeline, complete Tailwind removal in favor of component-encapsulated styles + optional @ngaf/chat/chat.css.

Closes the v0.0.2 publish friction this PR originally documented: consumers no longer need any Tailwind setup. `npm install @ngaf/chat` + drop `` in a template = working chat.

Spec & Plan

What changed

New components:

`` (floating bottom-right launcher + window)
`` (slide-in right panel, optional push-content)
`` (collapsible inline label with left-border indent — drives tool calls, subagents, timeline)
`` (header/body/footer layout shell)
`` (asymmetric user-bubble / assistant-inline variants + hover controls + streaming caret)
``, ``

Rewrites:

`` — asymmetric message pattern, traces inline above markdown, restyled empty state
`` — pill design, absolute send button, content-projection slots, focus-on-pill-click
`` — 3-dot animation
``, ``, ``, `` — all restyled, no Tailwind
``, `` — rewritten on ``
`` — vertical history walk
``, `` (+8 helpers) — restyled

Renamed:

`` → `` (`ChatMessagesComponent` → `ChatMessageListComponent`)

Removed:

`CHAT_THEME_STYLES`, `CHAT_MARKDOWN_STYLES` exports (replaced by component-encapsulated styles + optional `@ngaf/chat/chat.css`)
All Tailwind utility-class usage in chat library output

Token namespace renamed: `--chat-` → `--ngaf-chat-`

Updated downstream:

`libs/example-layouts` (both layouts rewritten without Tailwind)
3 cockpit demos required code changes (input, messages, theming); 16 already compatible
Website docs: install/quickstart/theming rewritten; new pages for chat-popup, chat-sidebar, chat-trace, layout-modes guide

Migration

```css
/* Before (0.0.2) — required */
@import "tailwindcss";
@source "../node_modules/@ngaf/chat";

/* After (0.0.3) — optional /
@import '@ngaf/chat/chat.css'; / only if you want :root token / global-class overrides */
```

```ts
// Before
import { ChatMessagesComponent, CHAT_THEME_STYLES } from '@ngaf/chat';
// After
import { ChatMessageListComponent } from '@ngaf/chat';
// CHAT_THEME_STYLES removed; tokens auto-apply via component encapsulation.
```

CSS variable consumers: rename `--chat-` → `--ngaf-chat-` (e.g., `--chat-bg` → `--ngaf-chat-bg`).

Test plan

All chat unit + conformance tests pass
All 19 cockpit chat + langgraph Angular demos build cleanly
example-layouts tests pass
Website builds (82 static pages, no MDX errors)
`dist/libs/chat/chat.css` ships in build output

🤖 Generated with Claude Code

The 0.0.2 publish workflow run failed with 'error retrieving identity token' on @ngaf/licensing and @ngaf/partial-json, and a 404 on @ngaf/a2ui. Root cause: actions/setup-node@v6.3.0 with node-version: 22 ships npm 10.9.2, which has partial OIDC code paths but doesn't fully implement the trusted-publishing flow against npm registry's OIDC endpoint. npm 11.5.1+ is required for trusted publishing. Adding 'npm install -g npm@latest' before the publish step bumps the runner to a current release.

@source

Verified against a fresh-install consumer of @ngaf/chat@0.0.2: without Tailwind configured (and without `@source "../node_modules/@ngaf/chat"`), ChatComponent's utility classes (flex, gap-3, max-w-[75%], md:flex, ...) are tree-shaken away and the chat collapses to a column of unstyled full-width blocks. The library does not ship a precompiled stylesheet, so this is a hard consumer-side requirement. Surface it explicitly: - Quickstart gets a Tailwind setup step between install and provider config. - Installation Requirements step calls out Tailwind v4 alongside Angular 20+ and Node 18+. - Tailwind CSS section is rewritten with concrete steps (postcss config, @import, @source) rather than just an `npm install` line.

Design for production-ready chat UI overhaul: asymmetric message pattern (user bubble + assistant inline), three layout modes (embedded, popup, sidebar), shared chat-trace primitive driving tool calls / subagents / timeline, complete Tailwind removal with encapsulated component styles + optional global chat.css. Settled architecture decisions: - Three separate compositions over a unified mode-switching one. - Hybrid styling: component-encapsulated + CSS vars + optional global stylesheet for deep overrides. - In-place rewrite of <chat>; coordinated breaking-change PR updates all 19 cockpit demos + libs/example-layouts + website docs in one shot. Ships as 0.0.3 (patch-only policy). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

56-task plan covering tokens (Phase 1), new primitives (Phase 2), existing primitive rewrites (Phase 3), trace-based card rewrites (Phase 4), top-level compositions (Phase 5), debug + interrupt panel (Phase 6), library cleanup + 0.0.3 bump (Phase 7), example-layouts (Phase 8), 19 cockpit demos (Phase 9), website docs (Phase 10), and verification + PR (Phase 11).

The click handler on the pill div violated angular-eslint's template/click-events-have-key-events and template/interactive-supports-focus rules. The textarea inside the pill receives focus natively when its visible area is clicked, so the handler was a redundant convenience.
