Move parseTableRow, isTableRow, isTableSeparator to module scope
so they aren't recreated on every convertTablesInJSX call. Fixes
eslint-plugin-unicorn(consistent-function-scoping) warnings. No
behavior change.
- Document every SNIPPET_MAP alias inline (AgUI/AGUI,
FrontendTools/FrontEndToolsImpl) so future maintainers can see why
the duplicates exist and don't collapse them blindly. Confirmed
FrontEndToolsImpl is still referenced from live MDX under
integrations/langgraph/*.
- Verified every SNIPPET_MAP target exists on disk with matching
casing (including migrate-to-1.10.X.mdx and migrate-to-1.8.2.mdx).
- Export FRAMEWORK_CATEGORY_ORDER (+ FrameworkCategory type) from
docs-render as the single source of truth. Consumer files
(sidebar-framework-selector.tsx, [[...slug]]/page.tsx) each define
the same constant independently today; a follow-up agent can
retire those duplicates once they pick up the import.
- Log the full Error instance (not just .message/.digest) so the stack
trace actually reaches the server log / browser devtools.
- Include the pathname (via usePathname) in the log message so reports
can be tied back to the page that crashed.
- Replace misleading migration-specific copy ("This page will be fixed
shortly. Some ... components are still being migrated.") with a
generic user-facing message — the error boundary catches errors from
many causes, not just migration gaps.
- Show error.digest explicitly as a reportable "Error ID" so users can
include it when reporting the issue; drop the fallback to
error.message because it can leak internal details in a user-facing
surface.
- Extract duplicated loadItems/getAllItems into @/lib/reference-items so the
/reference index page and the /reference/[...slug] page read the same
tree the same way (same subdirs, same walker, same gray-matter path,
same caching).
- Walker is now recursive: subfolder files like components/inputs/textarea.mdx
are indexed and statically generated. Previously only top-level .mdx
files under components/ and hooks/ were picked up.
- Wrap gray-matter and fs reads in try/catch per file: a single malformed
frontmatter block no longer crashes the whole static-generation pass —
we log the offending path and skip that file.
- Fence-aware import stripper in the slug page so code samples containing
import ... lines inside fences are not corrupted. (Duplicated inline
here and in ag-ui page with a TODO(dedup) marker pointing at a future
shared helper in @/lib/docs-render.)
- loadReferenceItems memoizes in production (module-scope cache keyed by
subdir). Dev bypasses the cache so edits show up without a server
restart.
buildNavTree walks the entire content tree on every page render and
calls readTitle / readMeta O(pages) times per request. Each call
previously reopened and re-parsed the file from disk.
- Process-scoped Map caches keyed by resolved absolute path.
- Null results are cached too — a missing or malformed file still
short-circuits on the second visit.
- Memory footprint is trivial: titles are short strings, meta is a
small JSON object.
- Stale-during-process semantics are acceptable for Next.js build
and server runtime lifetimes; authors re-run the process to pick
up MDX/meta.json edits (same as before in production builds).
- Replace local MDX components map with spread of shared docsComponents
from @/lib/mdx-registry, so AG-UI pages get the full component set
(Tabs, FrameworkTabs, Snippet, Steps from @/components/docs-steps,
etc.) instead of silently rendering raw JSX when MDX uses anything
outside the tiny local subset.
- Use the shared InlineDemo from mdx-registry, whose Open full demo
link uses an absolute NEXT_PUBLIC_SHELL_URL/integrations/... URL.
The prior local copy used a relative /integrations/... URL that 404d
on the docs host (no /integrations route on docs.showcase.copilotkit.ai).
- Parse frontmatter with gray-matter instead of a whole-file title:
regex that could match any title: line buried inside an MDX body.
- Wrap fs.readFileSync in try/catch with meaningful error logs naming
the offending path; fall back gracefully instead of crashing render.
- Fence-aware leading-import stripper so MDX code samples that show
import ... lines are not corrupted (duplicated here; TODO(dedup) in
comment to hoist into @/lib/docs-render next time another route needs
it).
- JSX_CONTAINER_TAGS now covers Callout, Card, Cards, Step, Steps,
Tabs alongside the original Accordion/Tab. Previously a Markdown
table inside e.g. <Callout> silently failed to promote to HTML
and rendered as raw pipes.
- convertMarkdownTableToHtml's parseRow and the row/separator
detection in convertTablesInJSX now accept GFM tables written
WITHOUT outer leading/trailing pipes (valid GFM — previously
rejected because we sliced (1, -1) unconditionally).
- readMeta now logs the offending path + parse error when JSON.parse
fails, replacing the silent catch. Malformed meta.json no longer
collapses to 'no nav ordering' with zero diagnostic signal.
- Clear selection button was hidden on /docs/* because it branched on
framework (URL-derived, always null there). A user landing on /docs
with a stale storedFramework from a previous session had no way to
clear the preference from the selector UI. Show the button whenever
framework OR storedFramework is set; skip the navigation when we're
not on a framework-scoped route (it's a pure preference change).
- router.push -> router.replace on framework change. Picking a backend
is a pivot on the same logical page, not forward navigation. Using
push clutters the back stack with every framework the user clicked
through, making the browser Back button useless.
- Type-guard e.target with instanceof Node before passing to contains,
rather than hard-casting. EventTarget can be non-DOM (e.g. events
against window); the cast silently degrades to contains(null) which
returns false in most engines but is undefined behaviour in spec.
- Document that stripFrameworkPrefix intentionally only inspects
parts[0] and does NOT recurse — /<fw>/<fw>/x must keep the inner
<fw>/x as the feature tail.
- Rename INTEGRATION_CATEGORY_IDS to FRAMEWORK_CATEGORY_ORDER to match
the identically-defined constant in /[[...slug]]/page.tsx (the two
will be consolidated into @/lib/registry in a follow-up owned by the
registry refactor; left a TODO pointing at the canonical home).
- sort_order tiebreak: Array#sort is not guaranteed stable for ties
across engines. When multiple integrations default to 999 the
rendered order shuffles between V8 revisions. Add an explicit
alphabetical-by-slug tiebreak so the rendered panel is
deterministic.
fallbackHref was assigned to href and then immediately overwritten in
every branch of the scope switch — the value was never read. Since
useFramework() returns the URL-derived framework identically during
SSR and post-hydration, the resolved href matches what fallbackHref
was pre-computing server-side, so the 'client takes over on mount'
comment was describing a no-op.
- Remove the dead assignment; resolve href directly from framework.
- Keep fallbackHref as an optional prop (ignored) to avoid churning
call sites that still pass it.
The effect had no dependency array, so it re-ran on every render and
hijacked the user's own sidebar scroll whenever any unrelated re-render
fired (state/context flips, parent rerenders). Key the effect on
pathname so scroll-to-active only runs on route change.
Also:
- behavior: 'instant' is a Chromium non-standard extension; other
engines silently ignore it. Use 'auto' which is the spec-compliant
'no smooth animation' value.
- Wrap scrollIntoView in try/catch — it can throw on detached nodes
and in obscure iframe/security contexts; a sidebar scroll
restoration never justifies taking down the route.
- Replace the global /^import\s+.+$/gm pass with a fence-aware walker
(stripLeadingImports). The old regex silently mangled docs code
samples like 'import os' inside Python fences; the new pass only
drops top-of-file MDX import lines and leaves fence bodies alone.
- Add Set<string> cycle tracking through inlineSnippets' recursion so
a self- or mutually-referencing snippet can't loop until the stack
overflows. On a repeat, emit a warning and inline a comment marker
so the author sees something diagnosable.
- Log warn when a <Component /> reference can't be mapped to a
snippet file (either missing from SNIPPET_MAP or missing on disk);
previously the reference silently rendered nothing.
- isMac now starts as null and is only resolved in useEffect, so SSR output matches the first client render; reserve horizontal space on the shortcut pill with a non-breaking-space placeholder (+ suppressHydrationWarning) so ⌘K/Ctrl+K swap-in doesn't reflow the button
- Cmd/Ctrl+K no longer hijacks the browser shortcut when focus is inside an unrelated <input>, <textarea>, <select>, or contenteditable; still toggles when focus is within the search modal itself (data-search-modal boundary)
- Trigger buttons use setOpen((prev) => !prev) so Cmd+K-on-top-of-existing-modal toggles correctly and the hint reflects the true action
- Replace useState<any> for registryData with typed Registry | null
- Surface registry-load failures: .catch logs + inline "Search index failed to load" banner
- Track the setTimeout focus id and clear it in effect cleanup
- Let static search-index matches render immediately; show a '[loading...]' hint until registry.json resolves; show 'no results' only after loading completes
- Use a ref for selectedIndex so Enter never reads a stale value after reset-on-input
- Dedupe results by type+href before slicing to 12 (stable key becomes type-href)
- Route navigation through a shared helper that detects external URLs (http(s)://, //) and uses window.location.assign for them, router.push otherwise
- Warn once in dev when an integration has no description so it gets fixed upstream
Add three dev-mode visibility affordances so MDX authors learn when
their embeds render nothing or when stub components silently discard
props:
- stub(name) helper wraps children-only shims and warns once per
(component, propKeys) pair when non-children props are passed.
Applied to Inspector and MCPApps as representative cases.
- warnSilentNull() + visible dev-mode fallback for FeatureIntegrations
when no deployed integrations support the requested feature.
- InlineDemo now warns (missing props, unknown slug, or not-deployed)
so authors see why their live demo didn't appear.
- Snippet base stub now emits a visible '[Snippet] runtime override
required' placeholder in dev so missing DocsPageView override is
obvious.
All warnings are gated on NODE_ENV !== 'production' and deduped so
HMR re-renders don't spam the console.
Slug paths reaching loadDoc and buildBreadcrumbs come straight from
URL segments. Before this change, path.join(CONTENT_DIR, slugPath)
would silently escape CONTENT_DIR when slugPath contained '..'
segments (e.g. /docs/..%2F..%2Fsecrets), letting an attacker read
arbitrary files the server process has access to.
- Add a tiny safe-fs helper (resolveWithinDir / safeExistsSync /
safeReadFileSync) that resolves a relative path under a declared
base and returns null when the resolved path escapes.
- Route loadDoc and buildBreadcrumbs through resolveWithinDir so any
traversal attempt collapses to a clean 'not found' fall-through.
- Apply the same guard to inlineSnippets' SNIPPETS_DIR reads for
defense-in-depth, even though its inputs are currently internal.
- Replace the silent empty `catch {}` with a proper error state:
clipboard write failures now set state to "error", surface a
"Copy blocked" label for 2s, and log the original error so devs
can debug (permissions, insecure context, etc.) instead of the
button failing invisibly.
- Collapse the two booleans into a single `CopyState` so idle/copied/
error styling and aria-label stay in sync.
- Guard `reg.code` as a string before rendering; malformed
`demo-content.json` (missing `code`, stale bundle) now produces a
visible WarningBox instead of crashing React on `undefined`.
- `resolveHljsLanguage` warns once per unknown language via a
module-scope Set, so authors learn the right names to use and stop
relying on hljs.highlightAuto guessing wrong.
- hljs try/catch now logs key/file/language + original error instead of
swallowing silently, so authors can spot bad snippets.
- When highlighting fails, drop the `hljs language-*` class so the
escaped plain-text fallback isn't styled as though it were highlighted.
- Defense-in-depth non-string hljs return guard.
- `regionFromFile` normalizes by stripping a single trailing newline
once, then splits — trailing-newline shape is consistent whether or
not `lines=` is supplied, so CopyButton text is predictable.
- Clamp `end` via `effectiveEnd = Math.min(end, allLines.length)` and
warn when an explicit range drifts past the file.
- Move the `WarningMessage` interface up next to the other type decls.
- Escape every interpolated value in convertMarkdownTableToHtml to
close an XSS vector: MDX table cells with HTML-significant characters
(e.g. <script>, &) previously landed raw in the generated markup.
- Scope readTitle and loadDoc title/description lookups to the
frontmatter block so a 'title:' / 'description:' that happens to
appear inside the MDX body (code samples, example config) can't
override the real frontmatter.
- Export a small escapeHtml helper for reuse within this module;
duplicated rather than imported from snippet.tsx to keep
docs-render server-only.
The img and video MDX shims spread props then overrode className to
undefined, silently dropping any className from authors' MDX. Remove the
bogus override so user-supplied className flows through.
Button had no type attribute, defaulting to type="submit" inside a
form (unintentional submits). Default to type="button", accept and
forward onClick/disabled/aria-label, and emit a dev-mode warning when
rendered without onClick so MDX authors learn their Button is
non-interactive.
IframeSwitcher had no sandbox attribute, letting user-controlled MDX embed
malicious-origin iframes with full browser capabilities. Mirror the
InlineDemo sandbox policy (scripts/same-origin/forms/popups) and add an
a11y title.
YouTubeVideo was missing both a title (screen readers announced only the
URL) and a sandbox policy. Add sandbox tuned for YouTube embeds
(scripts/same-origin/presentation/popups) and title fallback.
The component's name, comments, and stated purpose are to highlight the
user's remembered framework pick on the docs root pivot. The code was
keying off 'framework' (strictly URL-derived), which is always null on
/docs/* where this component is actually mounted — the 'Your choice'
badge and accent ring NEVER rendered.
Now reads 'storedFramework' (the remembered advisory preference) and
compares it against the card's slug, which is what the rest of the file
already documents it doing.
Functional regressions in the docs router pivot:
1. The redirect effect was reading 'framework' (URL-derived) only. On
/docs/<feature> the URL prefix 'docs' is never in knownFrameworks, so
'framework' is always null and the effect never fired. The whole
'picked-once, sticks' feature was silently broken — users with a
stored preference were never redirected. Now prefers URL framework,
falling back to storedFramework, as a single 'target' signal.
2. The 'Loading <framework> view...' placeholder was unreachable for the
same reason. Now renders when 'target' is set.
3. The supported/unsupported filters disagreed on whether 'deployed'
applied. supported = withCell (ignored deployed); unsupported =
!withCell && deployed. Now both require deployed; undeployed
integrations are omitted entirely rather than surfacing dead links.
4. FrameworkGuardedContent previously returned null whenever 'framework'
was null, which on /docs/* is always. The MDX body was permanently
hidden. Now it hides only while a redirect is imminent (URL framework
set, or storedFramework set — both cases are about to navigate away);
users with no stored preference see the pivot alongside the MDX body.
- Move highlight.js @import ahead of @import "tailwindcss" so Tailwind
utility layers can still override specific hljs selectors when needed
rather than being silently shadowed in Tailwind v4's layer ordering.
- Scope the dark-dimmed theme via prefers-color-scheme so it only
paints when the user's system is in dark mode. shell-docs does not
yet ship a dark theme, but this makes syntax blocks correct the
moment it does.
- useFramework() now throws when called outside FrameworkProvider instead
of returning a silent no-op context. Silent fallback was masking wiring
bugs where components rendered outside the provider would report no
framework forever.
- readStoredFramework / writeStoredFramework now log once per session on
failure (guarded by module-scope flags) instead of swallowing errors
entirely. localStorage may still be unavailable (SSR, private mode),
but devs get a warning the first time.
- Dropped 'stored' from the URL-persist effect's deps. It was causing
redundant re-check cycles every time we called setStored from within.
The internal !== guard still short-circuits the no-op case.
- setStoredFramework now validates against knownFrameworks. Previously
any string could poison the stored preference (e.g. a route segment
like 'docs'); invalid slugs now warn and no-op.
`docs_pageview` was firing on every matched request — HEAD probes,
POSTs, and Next.js router prefetches all counted as pageviews, which
inflated counts and polluted funnels. Next.js App Router prefetches
links via low-priority fetches that still hit middleware, so they're
especially noisy on pages with long link lists.
We now bail out of tracking when:
- the method is not GET
- `next-router-prefetch: 1` is set (Next.js App Router)
- `purpose: prefetch` is set (generic prefetch hint)
The response is still served normally; only the PostHog capture is
skipped.
- Add aria-hidden=true so the SHA is not announced by screen readers.
- Shorten to the conventional 7-char git short-sha (was 9).
- Distinguish 'dev' (NEXT_PUBLIC_COMMIT_SHA undefined) from 'unknown'
(env present but empty string) so Docker ARG-scope bugs surface as
something other than a misleading 'dev' label in production.
Three smaller cleanups to the middleware:
1. Matcher regex: `(?!api|...)` matched `/apidocs` as well as `/api`,
dropping analytics for any docs path whose first segment starts with
'api'. The pattern now uses `api/` with a terminator, and also
excludes `robots.txt`, `sitemap.xml`, `manifest.webmanifest`, and
the `.well-known/` prefix, which some static-path tooling expects
to reach without middleware interception.
2. Capture errors are now logged via `console.warn` rather than
silently swallowed. PostHog 401/403/5xx, DNS failures, etc. were
invisible to operators.
3. The missing-`POSTHOG_PROJECT_KEY` warning now fires once at module
load rather than via a module-scoped mutable flag. Edge runtime
isolates are short-lived and per-request, so the in-memory
warn-once flag was unreliable. Module-load is the cleanest
available single-fire hook.
If a registry integration ever ships a slug matching a top-level route
segment (docs, ag-ui, reference, api, matrix, integrations), the
FrameworkProvider.urlFramework resolver would treat the route as a
framework scope and hijack navigation. Filter those slugs out in the
root layout and log a dev-only console.error so the collision is
visible to the maintainer.
The previous hard-coded distinct_id ("docs-pageview-tracker") collapsed
every visitor into a single synthetic PostHog person, which destroyed
unique-visitor analytics.
Each visitor now gets a stable UUID minted on first visit, persisted
in a first-party `ph_distinct_id` cookie (Lax, Secure, ~2 year TTL)
and read back on subsequent requests. This avoids IP+UA hashing and
the PII concerns that come with it.
Also wraps the PostHog capture POST in `event.waitUntil()` — the
middleware signature now takes `NextFetchEvent` — so the Edge runtime
keeps the request alive until the POST resolves. A bare fire-and-forget
fetch can be torn down as soon as `NextResponse.next()` returns,
dropping events.
shell-docs renders pure MDX docs with iframed live demos (via <InlineDemo>
and <IframeSwitcher>) — it never instantiates the live copilot runtime
inline, so it doesn't need @copilotkitnext/react or its styles. Dropping
the import also removes the package from shell-docs's dep closure, keeping
the docs shell lean.
These files were added in #4085 but landed in showcase/shell/src/content/docs/
after the MDX-docs extraction had already moved the rest of content/docs into
shell-docs. Follow The Rule (MDX docs content belongs in shell-docs) and
relocate them so they render correctly on docs.showcase.copilotkit.ai.
Extracts everything that exists to render MDX documentation (docs/[[...slug]],
[framework]/[[...slug]], ag-ui/[[...slug]], reference/[...slug]) out of shell
into the new shell-docs package that will serve docs.showcase.copilotkit.ai.
Moves (git mv preserves history):
- App routes: /docs, /[framework], /ag-ui, /reference
- Docs-only components: docs-page-view, docs-callout, docs-steps, docs-tabs,
mdx-components, framework-tabs, framework-selector, sidebar-*, snippet,
property-reference, router-pivot, stored-framework-highlight, react/*
- Docs-only libs: lib/docs-render, lib/mdx-registry
- All content: content/docs, content/ag-ui, content/reference, content/snippets
- .docs-sync-sha marker (follows the content)
Duplicates into shell-docs (both shells need them):
- brand-nav, search-modal, search-trigger, copy-button, framework-provider
- lib/registry.ts, data/registry.json, data/demo-content.json,
data/search-index.json
- app/layout.tsx + globals.css + public/{images,logos}
shell-docs gets its own minimal middleware (PostHog-only — no SEO redirect
table, docs host never served legacy URLs). shell keeps seo-redirects.ts
for the legacy-URL migration table; framework-scope protection in its
middleware is now effectively dead but harmless (next.config.ts redirects
fire before middleware ever sees /<framework>/ paths).
InlineDemo updated for cross-host context: 'Open full demo' link points
at the shell host (showcase.copilotkit.ai) since the integration profile
route only exists there.
