No issue yet; I discussed this with @danielroe a few weeks ago on a call.

🧭 Context / 📚 Description

This PR (which I'm happy to split into multiple PRs - the commits are already designed for that) adds the concept of "security sources" to pair with the existing "data sources" concept, and makes OSV (the only current security source) into one. It then adds Socket as an additional security source. (Disclosure: Socket is my employer).

It's designed to follow the npmx philosophy of giving users control and choices by allowing them to see maximal security information, and if desired, hide any security source they wish. Additional security sources can be easily added in the future - Socket competitors won't have any less opportunity to display their data.

Additional disclosure: I used Claude Code pretty heavily on this PR, with a lot of guidance, adversarial LLM review, and also lots of manual human review throughout the process.

This is my first contribution to npmx, so please be gentle, and I'm more than happy to make any requested changes (including submitting this as multiple PRs, if commit-by-commit is too much for anyone).

Changes

Security source integration

Layer / File(s) Summary
Scanning contracts and source analysis
shared/types/*, shared/utils/security-sources.ts, server/utils/{osv,socket,dependency-analysis}.ts, modules/runtime/server/cache.ts, test/unit/server/utils/*, test/unit/shared/utils/*, test/e2e/vulnerabilities.spec.ts
The server queries OSV and Socket concurrently, reconciles findings, tracks source status, returns supply-chain alerts, handles caching and transient failures, and validates combined results.
Source preferences and controls
app/composables/useSettings.ts, app/components/Security/*, app/components/Settings/*, app/pages/settings.vue, nuxt.config.ts, playwright.config.ts, .env.example, CONTRIBUTING.md, i18n/*, test/nuxt/composables/*, app/pages/settings.stories.ts
The application stores source preferences, detects Socket availability, renders accessible controls, documents configuration, and validates unavailable and disabled-source states.
Package security presentation
app/components/Package/*, app/pages/package/[[org]]/[name].vue, test/nuxt/a11y.spec.ts, test/e2e/hydration.spec.ts
Package views filter findings by enabled sources and display source metadata, reachability, advisory links, supply-chain alerts, scan states, warnings, and hydration-safe output.
Comparison security facets
app/composables/usePackageComparison.ts, app/composables/useFacetSelection.ts, app/components/Compare/*, app/utils/compare-scatter-chart.ts, shared/types/comparison.ts, app/pages/search.vue, test/nuxt/components/compare/FacetSelector.spec.ts
Package comparisons expose source-aware vulnerability and supply-chain alert facets. Scatter-chart selections reset when security facets become unavailable.
Badge and endpoint handling
server/api/registry/badge/[type]/[...pkg].get.ts, server/api/registry/vulnerabilities/[...pkg].get.ts, test/unit/server/utils/osv.spec.ts
Badge generation uses the shared OSV count utility and returns an unknown badge for failed scans. Vulnerability responses use a five-minute cache.

279-289: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

The numeric fallback does not read CVSS vector strings.

OSV places a CVSS vector in severity[].score, for example CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The regex at Line 281 anchors on a trailing number, so a vector string never matches and the function returns unknown. The fallback then only helps for the rare records that store a bare numeric score.

Consider parsing the vector, or at least deriving severity from the CVSS_V3/CVSS_V4 vector components, so packages without database_specific.severity are not all reported as unknown.

Ambiguous null conflates "no advisories" with "query failed".

queryOsvDetails returns null at Line 89 when the detail response is empty, and also at Line 135 when the request throws. runOsvScan in server/utils/dependency-analysis.ts (Lines 61-67) counts every null as a failed query and reports partial. An empty-but-successful detail response therefore degrades the reported source status and, through the new validate hook, shortens the cache lifetime to five minutes.

Consider returning a discriminated result so the caller can separate the two cases.

Consider a test that pins counts for an unknown severity.

queryOsvDetails sets counts.total to the number of advisories and leaves unknown severities out of every bucket, while mergeSocketFindings recomputes counts with countBySeverity for any package Socket also reports. A test with one unknown-severity advisory, asserted both with and without a Socket finding for the same package, would lock the intended totals.

309-314: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Use Object.hasOwn for the alert-type lookup.

alert.type in VULNERABILITY_ALERT_DESCRIPTIONS also matches inherited Object.prototype keys, for example constructor or toString. alert.type comes from the Socket response, so such a value would be classified as a vulnerability, and the lookup at Line 214 would then assign a non-string value to the summary field typed as string.

The coding guidelines require strictly type-safe access, so prefer an own-property check.

🛡️ Proposed fix
-          if (alert.type && alert.type in VULNERABILITY_ALERT_DESCRIPTIONS) {
+          if (alert.type && Object.hasOwn(VULNERABILITY_ALERT_DESCRIPTIONS, alert.type)) {

Also guard the description lookup in toVulnerabilityFinding:

-      (alert.type ? VULNERABILITY_ALERT_DESCRIPTIONS[alert.type] : undefined) ??
+      (alert.type ? nonEmptyString(VULNERABILITY_ALERT_DESCRIPTIONS[alert.type]) : undefined) ??

Add pointer: fine to the hover guards.

The class list guards hover styles with [@media(hover:hover)] only. Some Android and stylus configurations report hover capability incorrectly, so touch users get sticky hover colours on the switch. Use the combined condition instead.

Write preferences through setSourceEnabled.

The page uses three write paths for the same state: socketEnabled.set writes settings.value.securitySources.socket (line 21), the OSV switch binds settings.securitySources.osv directly (line 301), and the composable already exposes setSourceEnabled. Use the composable setter in both places so the storage write stays in one location.

Playwright test webServer reuseExistingServer env existing server documentation

💡 Result:

In Playwright, the webServer configuration allows you to define a development server that starts automatically before your tests [1]. Below is a summary of how reuseExistingServer and env options function within this configuration: reuseExistingServer This boolean option controls whether Playwright should attempt to connect to an already running server at the specified port or URL [1][2]. - If set to true, Playwright will use the existing server if it is detected [1]. If no server is running, it will execute the command to start a new one [1]. - If set to false, Playwright will throw an error if an existing process is already listening on the configured port or URL [1]. - A common best practice is to set this to!process.env.CI [1][2]. This configuration allows the dev server to be reused during local development (where a server might already be running) while ensuring that, in CI environments, Playwright manages the server lifecycle, failing if the port is unexpectedly occupied [1]. env The env property allows you to define custom environment variables for the spawned server process [1][3]. - By default, the server process inherits environment variables from the parent process (the Playwright test runner), with the additional variable PLAYWRIGHT_TEST=1 injected [1][2]. - You can override or extend these variables by providing an object to the env option [3]. - While the server inherits process.env, explicit definitions in the config.webServer.env object will be merged with the parent's environment [3]. Example Configuration: import { defineConfig } from '@playwright/test'; export default defineConfig({ webServer: { command: 'npm run start', url: 'http://localhost:3000', reuseExistingServer:!process.env.CI, env: { NODE_ENV: 'development', MY_CUSTOM_VAR: 'value', }, }, });

Do not reuse an existing server for Socket-dependent end-to-end tests.

When reuseExistingServer is true, Playwright does not apply webServer.env to the existing process. Local runs can therefore use a server without the required Socket environment.

Set reuseExistingServer to false, or configure the existing server with the required Socket variables before the tests run.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift

Degraded entries lose all cache protection during a prolonged outage.

validate returns false for any degraded result older than five minutes. Nitro then treats the entry as absent and recomputes on the request path, so no stale value is served. While an upstream outage lasts, every request for that package past the five-minute mark re-runs the full tree scan, including the OSV batch query and its detail queries. The endpoint response cache in server/api/registry/vulnerabilities/[...pkg].get.ts absorbs part of this, but it uses the same five-minute window, so the two windows expire together.

Consider a floor on revalidation, for example keep the entry valid while a recomputation is in flight, or record the last attempt time and re-serve the degraded result until a retry interval elapses.

Good catch on the latent hole. effectiveSources iterates SECURITY_SOURCE_IDS but reads from the persisted object, and since mergeDefaults only shallow-merges, a source id added later would be undefined for existing visitors and leak into a boolean-typed slot. No current bug (osv/socket are both defaulted), but I've added the nullish fallback to DEFAULT_SECURITY_SOURCES so a newly introduced source defers to its default rather than undefined.

Good catch that the Socket source is server-configured (getSocketConfig gates on NUXT_SOCKET_API_KEY/ORG_SLUG), so the merged-sources fixture test does depend on those vars. In practice the reuse risk is narrow: the webServer command is TEST=1 vp run preview --port 5678, and reuseExistingServer only reuses a server already bound to :5678. A normal nuxt dev server is a different port and doesn't load the fixture plugin (TEST unset), so it's never reused. The only way to reuse a misconfigured server is to manually start start:playwright:webserver yourself without the dummy Socket env, which surfaces as a single obvious failing assertion rather than a silent bug. Forcing reuseExistingServer: false would slow every local run, break when :5678 is already held, and diverge from the !process.env.CI convention we use elsewhere, so I'm leaving it as-is.

Good catch that this is blocking rather than background — confirmed against nitropack 2.13.4: the SWR early-return is gated on validate(entry) !== false, so a degraded entry past the 5-min window does await a recompute on the request path rather than serving stale in the background. Two things make it much less severe than "every request past 5 min," though: pending[key] dedups concurrent recomputes, and each recompute resets mtime and re-stores, so the blocking recurs only about once per 5 min per key under steady traffic. On the suggested remedies: validate is a pure function of the stored entry (value + mtime only) evaluated before recompute, so "keep valid while a recompute is in flight" isn't expressible in Nitro's model. And "re-serve until a retry interval elapses" is in fact what the code already does — mtime is the last-attempt timestamp and the 5-min check is the retry floor; the only residual is Nitro's blocking boundary refresh, which validate can't change. The only way to get non-blocking early refresh would be to drop maxAge to ~5 min globally, multiplying OSV/Socket load for healthy entries. Deferring as an accepted, bounded tradeoff.

Good catch — parseArtifacts runs inside querySocketForTree's try, so one malformed/truncated NDJSON line currently throws and drops the entire chunk (up to 1024 packages) even though the other lines parsed fine. I've wrapped both the per-line NDJSON parse and the array-branch parse in try/catch: malformed lines are skipped and the successfully parsed artifacts are returned. Added a regression test asserting a valid artifact followed by a malformed line keeps the valid one.

Good catch, and it matches the existing convention in the repo (jsr.ts, docs/client.ts, npm-homepage.ts all set timeouts on third-party fetches). Added a 10s timeout via a shared constant to all three OSV $fetch calls (batch/details in the OSV-client commit, count in the could-not-check commit) and to the Socket purl request. All four already catch/degrade gracefully on failure, so the timeout just converts a hang into the existing failed-source path.

thanks for the PR! The abstraction of sources sounds good, it's similar to a mockup someone did in the Discord recently for data like this (security, module replacements, runtime compat data, etc)

Additional disclosure: I used Claude Code pretty heavily on this PR, with a lot of guidance, adversarial LLM review, and also lots of manual human review throughout the process.

no worries, thanks for letting us know! LLMs are allowed, we have a simple policy here: https://github.com/npmx-dev/npmx.dev/blob/bf230d7142e14709468aa5ed4ccf26c1900f25bf/CONTRIBUTING.md#using-ai

(including submitting this as multiple PRs, if commit-by-commit is too much for anyone).

The PR would likely be merged faster split up, purely as then aspects that involve design or discussion with the team can be talked about separately and won't block it as a whole. That being said, if it doesn't make sense to split up or merge different parts at different times then it can remain as one no problem

Fixed. beforeEach now captures previousSettings = localStorage.getItem('npmx-settings') and afterEach restores it (removing the key when there was none), so this test can no longer clobber the persisted settings later tests rely on in the shared browser context.

we're approaching this backwards to normal: a PR before a discussion.

to help us understand the feature better, can you:

  • briefly explain what you're trying to solve here
  • show some screenshots or preview URL links to packages which show the various notices
  • briefly explain the configurable part of this (the "security sources" and how a user can configure them or why. we should avoid making user options too noisy so we should discuss this part)

as with all agentic PRs, it is oversized. but we can solve that by splitting it up into incremental changes once there's better understanding of the intent and UX here

@43081j daniel and i already had the discussion :-) the goal is to add additional security data sources, and to surface socket's supply chain alerts on package pages. The configuration options are just checkboxes - OSV on or off, and socket on or off.

@danielroe the docs in the PR specify the packages:list scope; can you try that?

re the quote, that's unfortunately expected - the endpoint bills a flat 100 units per request (regardless of package count, up to 1024), and a default org token is 500/hour, so it's only ~5 package scans an hour. Each package page scans the whole transitive tree in one request. To keep it bounded npmx already caches results for an hour per package@version (re-opening a package is free) and trips a 10-minute circuit breaker on a 429/403, degrading to OSV-only instead of hammering the API - so "could not scan" is that back-off once the scope/quota check fails. For the public deployment we'd point it at a token provisioned with real-traffic headroom.

Extract the OSV API client out of dependency-analysis into a shared
server/utils/osv.ts, and additively extend the vulnerabilities API
response with per-source metadata:

- VulnerabilityTreeResult gains sourceStatus ({ osv: 'ok' | 'partial'
  | 'failed' }) so consumers can distinguish "no known vulnerabilities"
  from "could not check"
- VulnerabilitySummary entries are tagged with the sources that
  reported them
- cache keys bumped (route vulnerabilities:v1 -> v2, function v2 -> v3)
  for the new response shape
- results degraded by a transient source failure are only served from
  the dependency-analysis cache for five minutes instead of an hour,
  and the route response cache now matches its 300s ISR rule, so an
  OSV blip doesn't strip findings from caches long after recovery

The new metadata is additive; consuming it in the UI is a separate
change.
When a security data source fails, the UI reported a reassuring zero
rather than admitting it could not check. Consume the per-source
sourceStatus metadata to surface an unknown state instead:

- the public vulnerabilities badge rendered a green "0" when the OSV
  query failed; it now renders a slate "unknown" badge (and the badge
  reuses the extracted OSV client via a new fetchOsvVulnerabilityCount
  that returns null, not 0, on failure)
- the package page stats banner showed a check-marked 0 when every
  source failed; it now shows "-"
- the compare view coerced a failed vulnerabilities fetch to a clean
  zero count; unknown results are now excluded from table and chart
- the vulnerability tree now shows its "could not scan" state when a
  response carries no source data, instead of rendering nothing

Adds allSecuritySourcesFailed to drive these display decisions.
Introduce user-selectable security data sources. OSV - previously an
implicit, unnamed source - becomes the first entry in a checkbox list
that defaults to on:

- new securitySources setting (localStorage, SSR-safe via useMounted)
  with a useSecuritySources() composable exposing enabled/effective
  state and an any-source-enabled flag
- settings page gains a Security section with a per-source toggle
- new SecuritySourceToggle client/server component pair (compact
  popover with per-source checkboxes) rendered next to the search
  page's data-source switch and in the package page stats banner
- when every source is disabled, security surfaces show a scary
  warning instead of data: a SecuritySourcesWarning banner replaces
  the vulnerability tree, the VULNS stat shows a warning glyph, the
  compare table renders an explicit unavailable cell, and the
  vulnerabilities axis disappears from the compare scatter chart
- vulnerability findings are filtered client-side to enabled sources
  (filterVulnerabilityTreeBySources), so per-dependency shields,
  counts, and the compare table/chart always reflect the user's
  selection; compare derives its counts from the raw analysis result
  at render time; deprecation info comes from npm and is deliberately
  not gated
- "could not check" states are computed against the user's enabled
  sources (noEnabledSecuritySourceHasData), so a success from a
  disabled source can never mask a failure of the only enabled one

Server fetching is unchanged: the server always queries all configured
sources and caches per package; the checkboxes are purely a display
preference.

De-duplicate the package list before you read the cache and build chunks.

A dependency tree can contain the same name@version more than once. readPurlCache then pushes duplicate entries into misses, so the request body carries duplicate purls and consumes batch capacity for nothing. chunkFindings collapses the duplicates afterwards, so the extra purls have no effect on the result.

De-duplicate by ${name}@${version} at the entry point of querySocketForTree.

- Around line 3-4: Update the $fetchMock setup in the socket tests with explicit
request and response generic types, and add a helper that retrieves a mock call
while handling an absent call explicitly. Replace the non-null assertions around
the call inspections near the referenced test cases with this checked helper,
preserving the existing request and response assertions.

Integrate Socket (socket.dev) alongside OSV:

- server/utils/socket.ts queries Socket's org-scoped batch purl API
  (POST /v0/orgs/{slug}/purl?alerts=true, chunked at 1024 purls) for
  the full resolved dependency tree, policy-neutrally (no `actions`
  filter - npmx curates alert types itself). Compact responses are
  NOT used: they strip the alert props (ghsaId, cveId, title,
  reachability) that merging and display depend on. Credentials come
  from private runtimeConfig (NUXT_SOCKET_API_KEY / NUXT_SOCKET_ORG_SLUG);
  a public socketConfigured boolean signals availability to the client
  without exposing the key
- vulnerability alerts are merged with OSV findings by GHSA/CVE id or
  alias into single entries tagged with both sources, using match
  strength across all entries (exact id > primary GHSA > GHSA alias >
  CVE) so upstream alias-group pollution can't misattribute a finding;
  a source's authoritative one-to-one cveId pairing is preserved.
  Socket-only findings become their own entries. Reachability verdicts
  are attached (strongest wins on duplicates). Alert types with no
  advisory title (notably potentialVulnerability) get a descriptive
  fallback instead of "no description available"
- reconcileAliases strips aliases that provably belong to a sibling
  advisory and records them as disputedAliases so the UI can attribute
  the bad data to the source that supplied it
- a curated allowlist of supply-chain alerts (malware, typosquats,
  install scripts, obfuscated code, ...) is surfaced in a collapsible
  PackageSupplyChainAlerts banner; a supply-chain-alert count is shown
  next to the vulns count on the package stat banner and as a
  comparison facet (package-stats + compare)
- source labels render as small brand logos (Security/SourceLogo, a
  theme-aware <img> with alt text) in the settings toggles, the
  vulnerability rows (in per-source columns), and the supply-chain
  banner
- vulnerability rows show a severity chip and link both the GHSA and
  CVE ids; the collapsed preview guarantees each source a
  representative row so it can't read as single-source
- graceful degradation: no key -> 'unconfigured' (toggle disabled with
  a note, stored preference untouched); quota/auth 429/403 -> 10-minute
  circuit breaker -> 'unavailable'; failures -> 'failed'/'partial',
  cached only briefly so a blip doesn't strip findings for an hour
- .env.example and CONTRIBUTING document how a contributor obtains
  their own Socket API token (socket.dev dashboard -> Settings -> API
  Tokens, packages:list scope) and sets NUXT_SOCKET_API_KEY /
  NUXT_SOCKET_ORG_SLUG for local development
- cache keys bumped for the new response shape (route v2 -> v3,
  function v3 -> v4)
- fixture mode fabricates two-source findings for is-odd so e2e can
  assert the merged tree, dedup, reachability, and supply-chain alerts
- badges guide: the vulnerabilities badge now documents its gray
  "unknown" state for failed scans
- features guide + landing: security info comes from configurable
  sources (OSV + Socket with reachability and supply-chain alerts),
  with an explicit warning when every source is disabled

@43081j daniel and i already had the discussion :-)

I saw. Now we can have it here with the team 👍

Just context and examples goes a long way. Daniel has done it for you now but worth noting for future reference.

Generally the change seems sane. Would be good to split it up into a less monolithic change, though.

How we show these notices should be pretty abstract and unrelated to where it came from, as that is just an implementation detail. But being able to toggle sources seems fair enough

Totally happy to split up the PR - there's 5 commits and each one can land independently, although in a practical sense, aff3d5a and 60af5e6 can def land on their own, but 910f5c9 is a bit confusing without a second source, which 860fc76 provides. d9da7f5 can also land on its own, after everything else. So what I really see is 5 commits across 4 PRs - I can remove the last 4 commits from here, and put up a second PR - after those two have landed, I can put up a third (with 2 commits), and after that, a fourth with the 5th commit.

Give me explicit direction one way or the other, and I'll make it happen!
