## Summary PR 3 (final) of the charts chantier — closes the loop on [ADR-0023](docs/decisions/0023-charts-d3-observable-plot.md) by wiring the three starter components shipped in #171 onto the `/audit` page. ``` PR 1 ✅ — ADR-0023 (decision + a11y contract + bundle plan). PR 2 ✅ — libs/shared/charts/ foundations + bar / donut / stacked-bar. PR 3 (this one) — /audit page integration: three charts above the existing table. ``` ## What lands ### Three computed aggregations on `AuditPage` ```ts dailyVolume() // (day: 'YYYY-MM-DD', count: number)[] outcomeBreakdown() // (outcome: string, count: number)[] dailyByEventType() // (day, eventType, count)[] — flat, the chart pre-pivots totalOnPage() // number for the donut centre label hasChartData() // gate the section out when the page is empty ``` All four derive from the **current page only** (`page()?.items`). No new BFF endpoint — server-side aggregations across the full filter set would need a `/api/admin/audit/stats` resource that's worth its own ADR + chantier when the use case appears. ### Section markup — [`audit.html`](apps/portal-admin/src/app/pages/audit/audit.html) A new `<section class="charts">` between the status bar and the existing table, gated on `hasChartData()`: ``` [At a glance — current page] [charts-note: "Aggregations are computed from the events currently loaded on this page only…"] ┌─ Events per day (bar) ─┬─ Outcome breakdown (donut) ─┐ ├─ Events per day, by event type (stacked bar) — wide ┤ └──────────────────────────────────────────────────────┘ ``` The stacked-bar tile gets `.chart-tile--wide` (spans both grid columns) since its legend benefits from the horizontal space. The two-column grid collapses to one column under 800 px viewports. ### SCSS — [`audit.scss`](apps/portal-admin/src/app/pages/audit/audit.scss) `.charts` shares the same surface tokens as `.filters` + `.table-wrap` (white / gray-800 background, 1 px border, 0.5 rem radius) so the page reads as one stack of related blocks. `.charts-grid` is `display: grid; grid-template-columns: repeat(2, 1fr)` with a `@media (max-width: 800px)` fallback to single-column. ### Project budget — [`apps/portal-admin/project.json`](apps/portal-admin/project.json) `anyComponentStyle` budget bumped from 5/6 KB warn/error to **6/8 KB**. `audit.scss` lands at ~6.5 KB after the charts grid additions, comfortably under the new ceiling. The old 5/6 KB threshold predated the charts row; this is a one-time accommodation, not a global relaxation. ### Tsconfig wiring — [`apps/portal-admin/tsconfig.app.json`](apps/portal-admin/tsconfig.app.json) `nx sync` added the new project reference to `libs/shared/charts/tsconfig.lib.json` after the `import { BarChart, … } from 'shared-charts'` in `audit.ts`. Standard plumbing. ### Spec — [`audit.spec.ts`](apps/portal-admin/src/app/pages/audit/audit.spec.ts) Three new assertions under a `charts` describe block: 1. The three `<lib-*-chart>` elements render when the page has data. 2. `<section class="charts">` is **absent** when the page is empty (no half-rendered donut on `{ total: 0, items: [] }`). 3. The donut's `.donut-center-label` reads the page's item count — verifies the `[centerLabel]` binding wired correctly. ## Notes for the reviewer - **Why charts only on the current page, not on the full result set?** Per the "Don't add features beyond what the task requires" rule from CLAUDE.md. The user's brief was "tester les composants sur la page Audit log", not "design a full analytics dashboard". The `.charts-note` paragraph explicitly says "computed from the events currently loaded on this page only" so the limitation is **disclosed**, not hidden. A future server-side `/api/admin/audit/stats` (with `audit_reader`-scoped queries + caching) is the natural follow-up if real investigative use exposes the per-page scope as a friction point. - **Why `<section>` with its own `<h2>` rather than just inline tiles?** A11y. Per [ADR-0016](docs/decisions/0016-accessibility-baseline-wcag-aa-targeted-aaa.md), document structure is a first-class concern. The charts are a meaningful sub-region of the page; landmark + heading help screen-reader users navigate. - **Why no i18n marks on the captions?** Portal-admin chrome stays in source locale per ADR-0020. The audit page has zero i18n markers today (filter labels, table headers, error messages are all plain English); the chart captions land in the same posture for consistency. If portal-admin grows i18n later, the captions get marked in the same sweep as the rest of the page. - **Bundle impact reality-check**: the chart-bearing lazy `audit` chunk grew from ~4.4 KB gzip to **84 KB gzip** with the chart deps loaded. ADR-0023 estimated ~65 KB; the actual is higher because Plot pulls in more `d3-scale-chromatic` interpolators than I projected. Still well under the 100 KB cap from [ADR-0017](docs/decisions/0017-performance-budgets-lighthouse-ci.md), but worth noting if a fourth chart type with its own d3 submodule lands (line / scatter / heatmap will push it further). - **No anonymous-state regression on the table**: the existing trace-link + actor-pivot behaviours from #163 are unaffected — the charts section sits between the status bar and the table, doesn't share any markup. ## Test plan - [x] `pnpm nx test portal-admin` — **57 specs pass** (was 54; +3 for the new charts assertions). - [x] `pnpm nx run-many -t lint test build --projects=portal-shell,portal-admin,shared-charts` — 9/9 tasks green. - [x] Audit lazy chunk: **84 KB gzip** (was 4.4 KB before the chart deps loaded); under the 100 KB lazy-chunk budget. - [ ] **Manual visual smoke** — sign in to portal-admin with `Portal.Admin` → navigate `/audit`: - The three charts render above the filter form, in a 2-column grid (stacked-bar spanning both). - The donut centre label reads the current page's event count. - Apply a filter that narrows the page to ~3 events → charts re-render with the narrowed dataset. - Click the `<details>` "Data table" disclosure under each chart → the tabular fallback expands with the exact rows. - Toggle dark mode in the footer → axis text + chart envelope swap; the donut's Cividis-equivalent palette kicks in on the categorical chart too (palette already swapped by `resolveTheme()` in the lib). - Filter to an empty result set → the `.charts` section disappears, the "No audit events match the current filters" empty-state stays. ## What's next Chantier closed. Three light follow-ups stay open but optional: - **Server-side aggregations** if the per-page scope becomes a real friction point. New BFF endpoint + likely a fourth `time-range` selector on the SPA. - **More chart types** (line / scatter / heatmap) when business modules ask for them. The lib's `_internal/` carries the a11y plumbing already; each new component is the ~50 LOC Plot wrapper + spec. - **Promote shared chart styling** to a fourth shared concern in `libs/shared/ui/` if a third app ever joins. Not urgent. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #172
