fastx-dashboards 1.7.0

Dashboards for FastMVC: embed signing, revocation, theme params, Metabase/Grafana/Looker/PowerBI stubs, routers.

fast_dashboards

HTML dashboards for FastMVC: FastAPI routers and shared layout/CSS for operational UIs—health, API activity, queues, tenants, secrets, workflows—and a reusable render_dashboard_page layout helper. Also signed embed URLs (time-limited HMAC) and Metabase / Grafana embed helpers behind one protocol.

Python: 3.10+ · Dependencies: fastapi, httpx, loguru, pydantic>=2, sqlalchemy>=2 · Optional: PyJWT for Metabase (pip install 'fast_dashboards[metabase]').

What you get

• sign_embed_url, verify_signed_embed_url — append exp + sig (HMAC-SHA256) for iframe-safe dashboard URLs; optional signed tid (revocation id), theme, locale query params.
• EmbedRevocationChecker, InMemoryEmbedRevocationList — block leaked embeds by revoking tid before expiry.
• EmbedThemeParams, theme_to_extra_params — bundle dark/light + locale for sign_embed_url / Grafana.
• DashboardEmbedProvider, MetabaseEmbedProvider, GrafanaEmbedProvider — unified build_embed_url(resource_id=..., ttl_seconds=...); Grafana supports theme / locale / token_id; Metabase supports theme (URL fragment) and locale (JWT params).
• LookerEmbedProvider, PowerBIEmbedProvider — stubs; use Looker Signed Embed / Power BI GenerateToken (see below).
• Composite DashboardRouter — nested routers (health, API, queues, tenants, secrets, workflows); lazy-imported from the package root so fast_dashboards.layout works without the full host app on PYTHONPATH.
• layout.render_dashboard_page, BASE_CSS — shared HTML shell for dashboards with production SEO (Open Graph, Twitter Card, canonical URL when FASTMVC_PUBLIC_BASE_URL is set, JSON-LD WebPage + SoftwareApplication, theme-color, safe noindex, nofollow defaults for internal ops UIs).
• core.seo — PageSEO, render_seo_head, render_dashboard_inline_head, and robots_txt_* helpers for public sites vs private dashboards.
• Per-area routers — e.g. HealthDashboardRouter, ApiDashboardRouter, … (see src/fast_dashboards/).

Note: Many sub-routers expect host app modules (core.datastores, start_utils, configurations, …). Run inside a full FastMVC app or only import submodules you need (e.g. layout, embed_signing, providers).

Core vs dashboards: Generic “platform” building blocks that used to live under fast_dashboards.core (auth, tracing, encryption, smart cache, saga, etc.) are implemented in fast-platform under fast_platform.core (and fast_platform.caching). fast_dashboards.core still re-exports them for compatibility; prefer from fast_platform.core… in new code. Dashboard-only pieces remain here (layout, router, embed signing/theme/SEO, …).

Looker (recipe)

Looker Signed embed uses a server-generated SSO URL per session. Implement a small service that calls Looker’s API with your embed secret, then pass the returned URL to the iframe. Do not expect a static build_embed_url from this package — LookerEmbedProvider is a deliberate stub.

Power BI (recipe)

Use the Power BI REST API GenerateToken for reports/dashboards (Azure AD app registration). Return the embed URL + token to the client per Microsoft’s embed flow. PowerBIEmbedProvider is a stub pointing you to that flow.

Revocation example

from fast_dashboards import InMemoryEmbedRevocationList, sign_embed_url, verify_signed_embed_url

secret = b"your-32-byte-secret-here!!!!"
block = InMemoryEmbedRevocationList()
url = sign_embed_url("https://dash.example.com/view", secret, 3600, token_id="session-abc")
# Later: leak detected
block.revoke("session-abc")
assert verify_signed_embed_url(url, secret, revocation=block) is None
