Replaces the per-framework `::code-group` blocks in the docs with `::framework-tabs`: one code block, file header on the left, a framework picker on the right. The choice is a cookie shared by every group on the site and read on the server, so the first paint already shows the reader's framework.

```md
::framework-tabs
```ts [Nuxt] server/plugins/evlog-drain.ts
import { createAxiomDrain } from 'evlog/axiom'
export default defineNitroPlugin((nitroApp) => {
nitroApp.hooks.hook('evlog:drain', createAxiomDrain())
})
```
```ts [Hono] src/index.ts
import { evlog } from 'evlog/hono'
import { createAxiomDrain } from 'evlog/axiom'
app.use(evlog({ drain: createAxiomDrain() }))
```
::
```

  • Registry in `app/utils/frameworks.ts`: colour marks from `@iconify-json/logos` (new docs devDependency), Nitro's gradient mark, TanStack/oRPC marks from their repos. No tinting; the `codeIcon` map is gone.
  • Every wiring group now covers Nuxt, Nitro, Next.js, SvelteKit, TanStack Start, React Router, Hono, Express, Fastify, Elysia, NestJS, oRPC, Cloudflare Workers, Standalone.
  • Fixes docs that passed a non-existent `enrichers` option: now `enrich` / `composeEnrichers` on middlewares and `plugins: [enricherPlugin(...)]` on `initLogger`.
  • Fixes `fs.md`, where a callout inside the group split six fences out of it.
  • `test/framework-tabs.test.ts` guards the fence-meta convention; `apps/docs/AGENTS.md` and the content skills describe it.

SSR check: `curl -H 'Cookie: evlog-framework=hono' /integrate/adapters/cloud/axiom` renders the Hono snippet; no cookie renders Nuxt.

No changeset: `apps/docs` only.

Summary by CodeRabbit

  • New Features
    • Added framework-aware code tabs that follow your site-wide framework selection and display matching examples across 14 frameworks.
    • Added a framework picker for switching the site-wide selection; tabs without a matching framework can still be selected locally.
    • When an example isn’t available for the selected framework, tabs fall back to a standalone example or display a missing-example message.
  • Documentation
    • Expanded framework-specific examples across setup guides, integrations, and use cases.
    • Updated example labels and guidance to clarify framework-specific setup instructions.

📝 Walkthrough

Walkthrough

The docs site adds framework-aware code tabs with a shared framework choice and registry-based labels and icons. Documentation updates examples across setup, learning, adapter, use-case, extension, and reference pages. Authoring guidance and tests cover framework-tab formatting and framework-label resolution.

Changes

Framework Tabs and Documentation

Layer / File(s) Summary
Framework tab behavior and guidance
.agents/skills/*, apps/docs/AGENTS.md, apps/docs/app/*, apps/docs/test/*, apps/docs/package.json
The docs site adds FrameworkTabs, a framework registry and resolver, cookie-backed selection, and framework-aware code icons. Guidance and tests describe and check framework-tab labels and fence metadata.
Getting-started and learning examples
apps/docs/content/1.start/*, apps/docs/content/2.learn/*, apps/docs/content/3.cli/*
Getting-started, learning, and CLI examples use framework tabs and add framework-specific request logging, route configuration, sampling, lifecycle, and error examples. Several example filenames change to service paths.
Adapter integration examples
apps/docs/content/4.integrate/adapters/*
Adapter overview and provider guides use framework tabs and add or expand setup and configuration examples across supported frameworks.
Use-case examples
apps/docs/content/5.use-cases/*
Use-case guides update examples for client logging, AI SDK, authentication, telemetry, audits, signals, and enrichers with framework-specific tabs and integrations.
Extension and reference examples
apps/docs/content/6.extend/*, apps/docs/content/7.reference/*
Extension and reference guides update examples for plugins, enrichment, drains, pipelines, middleware, redaction, and logging practices.
Lab content-stage exclusion
apps/lab/modules/stages.ts, apps/lab/nuxt.config.ts
Stage sources can exclude matched filenames. The content-stage configuration excludes FrameworkTabs.vue.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Add file paths to the Standalone tabs.

Both framework-tab fences omit the file path required after the framework label. Add each example’s intended path so its code header identifies where to put the snippet.

  • apps/docs/content/6.extend/5.custom-enrichers.md#L386-L386: add the intended file path after [Standalone].
  • apps/docs/content/6.extend/8.custom-drains.md#L247-L247: add the intended file path after [Standalone].

Based on learnings, framework-tab fences use “the file path after the brackets as fence meta.”

- Line 287: Update createTenantEnricher to derive the tenant ID from
authenticated context instead of the client-controlled x-org-id header, or
ensure trusted middleware removes the incoming value and replaces it after
authentication before the enricher uses it.

Review comments at @apps/docs/content/7.reference/4.best-practices.md:
- Line 447: Update the sanitizer in the definePlugin hook to compare normalized
event keys against normalized sensitive-key patterns, so apiKey is redacted
regardless of casing. Recursively sanitize object elements in arrays before
forwarding events to the external drain.

Review comments at @apps/docs/test/framework-tabs.test.ts:
- Line 44: Update the fence collection helper used by the `offenders` filter to
collect each fenced block’s lines through its closing delimiter and store them
as the fence body. Ensure the Nitro syntax regex tests that collected body, so
Nitro v2 examples are detected and the code no longer accesses an undeclared
`Fence.body` property.

Sensitive Data Exposure

Reachability: Internal
Exploitability: Moderate
CWE: CWE-532 — Insertion of Sensitive Information into Log File

Normalize separators in API-key field names.

For an api_key field, lowercasing preserves the underscore, so the apikey pattern does not match. deepSanitize copies the secret into its result. Normalize separators in both field names and sensitive-key patterns in every example.

Confirm that each drain callback forwards this result without another redaction step:

#!/bin/bash
set -euo pipefail
rg -n -C 12 'deepSanitize|evlog:drain|createEvlog|redact:' apps/docs/content/7.reference/4.best-practices.md
