Documents the published V2 frontend node API: registration and lifecycle, definitions, graphs and nodes, slots and links, widgets and mounted UI, execution and resolution, application services, legacy migration recipes, and the generated reference for each of the eight declaration sections. Twenty-four pages, placed beside the existing "JavaScript (UI)" section rather than replacing it: V1 packs keep working and their documentation stays where authors expect it. Scope is deliberately the JavaScript half. The V2 Python API, and anything about hosted or isolated execution, is not documented here. The section is generated from a shared source by `prepare-publication.mjs`, which materialises one variant as committable MDX and refuses to hand over a tree that still carries a review banner, Python SDK surfaces, or working notes. `public/custom-nodes-sdk/v2/comfy-api.d.ts` is the declaration the reference pages are generated from and link to, so the download links resolve once this merges.

- Line 91: Rewrite the existing MAGIC PATCH migration sentence in the
custom-node migration documentation to use a neutral, technical description of
what MAGIC PATCH does, removing the Claude Code/Codex brand references and
promotional comparison to Comfy’s pack catalog while retaining the link to the
frontend migration mappings.
- Line 6: Update the opening description of the Custom Nodes frontend SDK to use
“V2” instead of “2.0,” matching the terminology used throughout the page,
including the “V1 and V2 pack layout” heading.
In `@custom-nodes/v2/javascript/definitions.mdx`:
- Line 74: Rewrite the sentence around “Structural changes to a live node” to
remove the dash-delimited clause, using parentheses around the dynamic slots,
values, ordering, and connections list or splitting it into a second sentence
while preserving the original meaning.
In `@custom-nodes/v2/javascript/execution.mdx`:
- Around line 206-207: Update the resolver documentation to allow asynchronous
implementations returning a Promise, noting that prompt construction awaits
them; clarify that synchronous readers such as resolvedSource() report
asynchronous results as unresolved rather than requiring resolvers to be
synchronous.
In `@custom-nodes/v2/javascript/slots-links.mdx`:
- Around line 229-231: Update the output variant in the ResolvedSource examples
to use the fields kind, nodeId, and output, removing graphId and outputIndex so
the documented shape matches the generated contract.
In `@custom-nodes/v2/reference/javascript-core.mdx`:
- Around line 21-22: Replace em dashes in the authoritative declaration comments
for BackendHandle, ExecutionResult, DocumentHandle, and QueueHandle.run with
approved punctuation, then regenerate the reference pages. This applies to

Source: Coding guidelines
`ResolvedSource` for `kind: 'output'` carries `nodeId` and `output`. The page listed `graphId` and `outputIndex`, neither of which the declaration defines, so code copied from it would have read undefined. Resolvers may be asynchronous: `Resolver` returns `Record<string, OutputResolution> | Promise<...>`, and prompt construction awaits it. The page said a resolver must be synchronous, which would have led authors to reject supported implementations. What is actually true is narrower, and now stated: the synchronous readers cannot wait, so `resolvedSource()` and `resolvedSupplies()` report a pending resolver as unresolved. Also drops a marketing clause from the migration sentence, aligns the opening line on "V2" rather than "2.0", and replaces a dash-delimited clause with parentheses. Not fixed here: the em dashes in the generated reference prose come from JSDoc in `comfy-api.d.ts`. Editing the rendered page would break the generator's drift check; the declaration is where that belongs.

Thanks — two of these were real contract errors, and both are fixed in 61fb4b8. Fixed
Not fixed, with reason

Reverts one of the two changes in 61fb4b8. The contract defines two similar types, and the review finding — and my verification of it — matched the wrong one. `ResolvedSource` (comfy-api.d.ts:2004) is `{ kind: 'output', nodeId, output }` and describes where an output lands after the resolver chain runs. `ResolvedInputSource` (:2367) is `{ kind: 'output', graphId, nodeId, outputIndex }`, and that is what `InputSlotHandle.resolvedSource()` returns (:2405) — which is the call this page documents. The original text was right. The other half of 61fb4b8 stands: `Resolver` does return `Record<string, OutputResolution> | Promise<...>` (:1997-2001), so resolvers may be asynchronous.

Correction to my previous comment — I was wrong about the first finding, and have reverted it in 208d9ae. The contract defines two similar types:
The second finding stands and remains fixed: |

Filtering the shared source down to the JavaScript pages left the first three sections holding one page each, so the sidebar showed three folders that each opened onto a single article. "Getting started" was the worst of them: a folder whose only child was a page also titled "Getting started". Merged into one opening section that follows the reading order — overview, the handle and lifecycle model, then the tutorial — and retitled the landing page to "Overview" so it no longer repeats its container. Sections are now 3, 11 and 10 pages, with no singletons. No page was added, removed, or reordered within a section.

Important
Merge after the frontend SDK PR in
Comfy-Org/ComfyUI_frontend. The example guide describes theexamples/node-apipacks, which land there. Merging this first leaves that one page describing files that do not exist yet.Adds documentation for the published V2 frontend node API — the JavaScript half of Custom Nodes SDK V2.
What this adds
24 pages under
custom-nodes/v2/, in a new Custom Nodes SDK V2 (JavaScript) section placed directly after the existing JavaScript (UI) group:public/custom-nodes-sdk/v2/comfy-api.d.tsis the declaration the reference pages are generated from. The reference pages link to it at that path, so the download links resolve once this merges.Scope
Deliberately the JavaScript half only. The V2 Python API is not documented here, and neither is anything about hosted or isolated execution. V1 documentation is untouched — the existing JavaScript (UI) and Python (Backend) sections stay exactly where authors expect them.
The pages are generated from a shared internal source by a script that materialises one variant as committable MDX and refuses to emit a tree carrying a draft banner, Python SDK surfaces, or internal working notes.
Checks

Visual QA has not been done — desktop, mobile, dark mode, and search are untested, because no browser was available while this was written. The preview build on this PR is the way to close that. Please look at the rendered pages rather than trusting the structural checks alone.
