What and why

The TransferState payload showed the request URL instead of the cache key for HttpClient and Analog entries, so the key an "Edit TransferState entry" override needs was not visible in the panel.

  • Each opened payload entry shows its key as selectable text with a Copy button. The result is announced in the toolbar status ("Copied." or "The clipboard is not available here.").
  • Edit in SSR overrides fills the SSR overrides form with the kind, the key and the page path, and moves focus to New JSON value. It is shown only when the actions.http write action is on and the key fits the 200 character limit of set-ssr-overrides.
  • The value starts empty on purpose: the panel only has a redacted and clipped copy of the entry, and for HTTP entries it holds only the body, not the cache record. A note under the field says so. The pattern leaves out the query string, which the panel only has in redacted form.
  • The value of an entry is now focusable, so it can be scrolled with the keyboard (axe scrollable-region-focusable).
  • Docs: inspectors/ssr-http.md.

No RPC, data shape or server change.

How it was verified

  • pnpm format:check
  • pnpm typecheck (no TS or NG errors)
  • pnpm test:panel (30 files, 169 tests), with the new network-payload-key.test.ts (5 tests)
  • pnpm docs:build
  • pnpm extension:build, extension/ui committed
  • scripts/panel-axe.mjs on the static report, dark and light (29 of 29 checks), run on the installed Chromium 1194 because pnpm test:axe could not launch its pinned one
  • Live on the SSR demo (/examples/ssr): axe clean in dark and light with entries open and the form filled, no horizontal overflow at 1280px and 360px, Copy and Edit tested by keyboard
  • pnpm commit:check

Screenshots

None attached.

Notes for reviewers

Summary by CodeRabbit

  • New Features

    • TransferState entries now offer Copy and, when available, Edit in SSR overrides. Editing pre-fills the key and page pattern, leaves the value empty, and focuses the form.
    • Added clear feedback when copying is unavailable and an explanation when a value was prefilled from a payload.
  • Bug Fixes

    • Root-page overrides now start with a blank pattern, avoiding unintended matches across all pages.
  • Documentation

    • Updated SSR override guidance to explain editing payload entries, cache keys, and value requirements.

The TransferState payload showed the request URL instead of the cache key
for HttpClient and Analog entries, so the key that an Edit TransferState
override needs was not visible anywhere and had to be found by hand.

Each opened entry now shows its key as selectable text with a Copy button.
When HTTP writes are allowed, Edit in SSR overrides fills the override form
with the key and the page path and moves focus to the value. The value
starts empty because the panel only has a redacted, clipped copy of the
entry. The value of an entry can now be scrolled with the keyboard.

📝 Walkthrough
📝 Walkthrough

Walkthrough

NetworkInspector now displays TransferState keys with copy actions and can open eligible entries in SSR overrides. The draft prefills the key and page-path pattern, leaves the value empty, and displays a note about the redacted payload. Tests and documentation cover these behaviors.

Changes

TransferState payload editing

Layer / File(s) Summary
Display and copy payload keys
app/src/pages/network-inspector.ts, app/src/__tests__/network-payload-key.test.ts, extension/ui/index.html, extension/ui/assets/browser-agent-rpc-...js
Payload entries show their keys and Copy actions. Clipboard success and unavailable states are covered by tests. The extension UI references the updated JavaScript asset.
Open payload entries in SSR overrides
app/src/pages/network-inspector.ts, app/src/__tests__/network-payload-key.test.ts, apps/docs/src/content/inspectors/ssr-http.md
Eligible entries open a draft with a prefilled key and page-path pattern, an empty value, and a note about the redacted payload. Tests and documentation cover root-page patterns, key constraints, focus, and disabled HTTP writes.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature



Merge Risk: ⚪ Minimal · up to 2b73e

TransferState keys can be copied, and eligible entries can seed SSR override drafts. The reviewed changes leave no actionable merge-blocking risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 2b73e

The shortcut preserves explicit submission and the existing write permission. Its page pattern can affect multiple matching URLs, as the form already explains. No introduced permission bypass or security vulnerability was established, but deployment-wide exposure was not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — For a submitted override, effective scope is all enabled matching request URLs handled by the existing SSR middleware and containing the targeted TransferState key—not necessarily only the selected page. The shortcut does not grant additional server authority.

Trust Boundaries and Controls

  • observed — Page-reported payload data remains distinct from write authority. Client eligibility requires HTTP writes and a compatible key; explicit submission crosses the existing RPC boundary, where the server independently rejects disabled HTTP actions and sanitizes the override list.

Resilience and Maintainability Implications

  • observed — The unchanged response-editing path preserves the original response when no applicable state script or editable state is available, and records non-applied outcomes. The new draft action does not weaken this failure-containment behavior.

The "Workers Builds: angular-devtools" check fails here the same way it fails on every open PR right now (#244 to #272 included), including PRs that do not touch the docs site. Its logs are only on the Cloudflare dashboard, so the cause can't be seen or fixed from this branch. The repo's own checks for this change (format, typecheck, panel tests, docs build, extension build, commit check) pass locally.

- Line 2293: Update the `pattern` initialization so selecting a site-root page
does not prefill `/` as a page-specific override. Require an explicitly entered
pattern for the root page or use a page-specific form that cannot match other
pages before allowing the draft to be saved.
- Line 2280: Update the edit-action eligibility check in the canWrite guard to
exclude empty keys and keys that differ from their trimmed form, while
preserving the existing MAX_OVERRIDE_KEY length limit so editing only targets
keys that sanitizeSsrOverrides will preserve exactly.

Comment thread app/src/pages/network-inspector.ts Outdated
Override patterns match anywhere in the URL, so prefilling `/` for the
site root made the edit apply to every page. The pattern now stays empty
there and gets focus. The edit is also hidden for keys with spaces at
either end, because the override would trim them and target another key.
…tale note

A key the server masked can never match the real one, so Edit in SSR overrides is hidden for it. The note that the form was filled in from the payload now goes away when the key, the kind or the page changes.
