Summary by CodeRabbit

  • New Features
    • Added a read-only API store for retrieving JSON records by key, with optional bearer-token authentication.
    • Mapping rules can now require consent in addition to destination consent. Events wait, are skipped, or are dropped according to the flow type.
    • The complete-flow example now includes a product lookup route that returns product data or a 404 for unknown products.
  • Bug Fixes
    • File requests within a configured prefix now return 404 when missing; store-read failures return 503. Unusable stores prevent startup.
    • Source caches no longer retain 5xx responses.
    • Missing walker.js requests return a no-store 404 instead of a tracking pixel.
  • Documentation
    • Updated guides and examples to explain consent, API stores, file responses, and route patterns.

Walkthrough

The changes add destination mapping-rule selection and consent enforcement, a read-only HTTP API store, file-transformer response handling, and product lookup routes in the CLI example. Source caching now excludes 5xx responses.

Changes: Mapping Rule Selection and Consent

Layer / File(s) Summary
Mapping and consent contracts
packages/core/src/consent.ts, packages/core/src/mapping.ts, packages/core/src/types/destination.ts, packages/core/src/schemas/mapping.ts, packages/core/src/types/mapping.ts, packages/core/src/types/simulation.ts, packages/core/src/causeLog.ts, packages/core/src/mapping-no-ops.ts, packages/core/src/__tests__/*, .changeset/core-rule-selection.md, .changeset/rule-consent-enforced.md, apps/walkerjs/src/__tests__/integration/dist.test.ts
Core adds helpers to collect and check consent requirements and select mapping candidates in exact-to-wildcard order. processEventMapping accepts an optional resolved rule, and queued destination entries can retain a selected result.
Destination selection and consent admission
packages/collector/src/destination.ts, packages/collector/src/selection.ts, packages/collector/src/__tests__/destination.rule-consent.test.ts, packages/collector/src/__tests__/selection.test.ts
The collector selects destination rules before admission and checks both destination and rule consent. It retains selections through queueing and delivery, handles asynchronous conditions, and reports renamed before-chain events when the carried rule was not applied.
Source consent and reporting
packages/collector/src/push.ts, packages/collector/src/observerEmit.ts, packages/collector/src/__tests__/source.rule-consent.test.ts, packages/cli/src/commands/push/__tests__/simulate-consent.test.ts, packages/mcps/mcp/src/*, skills/walkeros-*/SKILL.md, website/docs/{apps/cli.mdx,collector/*,guides/consent/index.mdx,guides/debugging.mdx,mapping/*}
Source mapping consent includes matched-rule requirements. Consent skip records can include a mapping key, and guidance describes rule consent and destination selection timing.

Read-Only HTTP API Store

Layer / File(s) Summary
Store settings and public types
packages/server/stores/api/src/{types.ts,schemas/*,index.ts}, packages/server/stores/api/{package.json,tsconfig.json,tsup.config.ts,jest.config.mjs}, packages/server/stores/api/README.md, .changeset/server-store-api.md
The new package defines its settings schema, public types, exports, and build configuration.
HTTP reads and outcomes
packages/server/stores/api/src/store.ts, packages/server/stores/api/src/hints.ts, packages/server/stores/api/src/__tests__/store.test.ts
The store validates URL templates, credentials, and keys, then performs timed GET requests with optional bearer authorization. It returns misses for 404, 204, or JSON null, reports transport or decode errors, and rejects writes.
Examples and store integration
packages/server/stores/api/src/examples/*, packages/server/stores/api/src/dev.ts, packages/server/stores/api/src/__tests__/stepExamples.test.ts, website/docs/stores/*, website/package.json, website/sidebars.ts, packages/cli/examples/customers/README.md, skills/walkeros-understanding-flow/SKILL.md, skills/walkeros-understanding-stores/SKILL.md, skills/walkeros-using-store-cache/SKILL.md
The examples include path- and query-based configurations and an in-memory fetch environment. Tests cover example flows, and the documentation describes configuration, outcomes, and cache behavior.

File Responses and Product Routes

Layer / File(s) Summary
File ownership and response handling
packages/server/transformers/file/src/transformer.ts, packages/server/transformers/file/src/types.ts, packages/server/transformers/file/src/schemas/settings.ts, packages/server/transformers/file/src/examples/step.ts, packages/server/transformers/file/src/__tests__/*, packages/server/transformers/file/README.md, packages/server/transformers/file/package.json, .changeset/file-step-answers-404-503.md, website/docs/transformers/file.mdx, skills/walkeros-understanding-transformers/SKILL.md
The file transformer validates its store at startup and applies prefix-based path ownership. Missing owned files return no-store 404 responses; store-read errors return no-store 503 responses and fail the push.
Product lookup example and validation
packages/cli/examples/flow-complete.json, packages/cli/examples/flow-complete.md, packages/cli/examples/shared/*, packages/cli/src/examples/flow-complete.manifest.ts, packages/cli/src/__tests__/integration/examples/flow-complete-simulate.test.ts, .changeset/flow-complete-product-lookup.md, packages/server/sources/express/src/schemas/primitives.ts, .changeset/express-route-path-text.md
The example routes /demo/products/:id requests to a file transformer that serves product JSON. Integration tests check product and script responses and verify that these routes do not reach destinations.

Source Cache Status Handling

Layer / File(s) Summary
Cache 5xx responses and tests
packages/collector/src/source.ts, packages/collector/src/__tests__/source-cache-integration.test.ts, .changeset/source-cache-no-5xx.md, website/docs/transformers/file.mdx
Source cache misses with status 500 or higher are not stored. Tests cover 500, 503, 404, and 200 responses.

The change is mergeable with bounded follow-up: some valid API URLs fail startup, HTTP configurations can expose bearer tokens, and error responses need cleanup. File-routing edge cases and CLI consent guidance also need correction.

Major · Functional Correctness · Quick win

Use an own-property check for mapping rule lookup.

The lookup mapping[e]?.[a] also reads inherited Object.prototype members. An event named constructor name selects the string Object as its rule. That rule has no ignore flag, so a * * ignore rule is never tried. Check own properties before reading a rule.

Suggested fix
-    const rules = mapping[e]?.[a];
+    const row = Object.prototype.hasOwnProperty.call(mapping, e)
+      ? mapping[e]
+      : undefined;
+    const rules =
+      row && Object.prototype.hasOwnProperty.call(row, a) ? row[a] : undefined;

Ignore cached 5xx entries on read, not only on write.

The HIT branch serves any unexpired cache entry, including a 5xx written before this change. Requests keep receiving that failure until the entry's ttl ends. Treat a cached status of 500 or higher as a MISS on read, or purge those keys during deployment.

Put the token in the failed-fetch fixture so the redaction assertions cover that path.

The "never logs the token" test rejects with new TypeError('fetch failed'). That message has no token, so the not.toContain(TOKEN) checks cannot fail if fetch error text reaches the logs. The current logger keeps only the cause's name and code, so the test passes today. A future change that logs the cause message would also pass. Include the token in the rejected error so these assertions detect that change.

Assert that the store's request signal times out after 5000 ms.

The 'a timeout' case rejects before it reads the signal. Its only check on the signal is toBeInstanceOf(AbortSignal), which also passes for new AbortController().signal. If AbortSignal.timeout(TIMEOUT) were replaced with a signal that never aborts, every test in this file would still pass.

Add a check that the store creates the signal with the 5000 ms timeout. For example, spy on AbortSignal.timeout around store.get and assert its call argument. This check does not wait for the timeout, so it does not depend on timers.

Suggested approach

Spy on AbortSignal.timeout before calling store.get('cust-42'), assert that it was called with 5000, and restore the spy after the test.

Validate the URL returned by parseUrl before issuing requests, while preserving
HTTP support when no authorization header is sent.
- Around line 158-159: Update the response handling around the res.status and
res.ok checks so the body is consumed or canceled before returning undefined for
404/204 or throwing for other failures. Preserve failedResponse(res)’s intended
error details, ensuring body cleanup does not prevent their construction.

denied events are always retained. Update the consent behavior description to
clarify that events are held in the destination queue only when consentDenied is
'queue', while CLI server flows default to 'skip' and do not retain them;

Move the /demo/products/ case above the .js suffix case.

before.one selects the first matching case. The .js suffix case at lines 1934-1941 matches /demo/products/<id>.js before the product case at lines 1950-1957 is evaluated. Those requests go to file, which looks up demo/products/<id>.js and returns 404, even when products/<id>.js exists in the assets store.

Validate the store URL with the same rules storeApiInit enforces.

SettingsSchema checks only that url is a non-empty string. The store init rejects URLs that the schema accepts, so the CLI validator reports a valid configuration that fails when the flow starts. Examples are ftp:// URLs, URLs without {key}, and URLs where {key} comes before the host.

Accept explicit default ports in settings.url.

parseUrl compares the raw URL prefix with parsed.origin. URL removes default ports, so https://crm.example.com:443/customers/{key} fails the next check and throws a config error during store init. The documented contract accepts any absolute http or https URL with one {key} after the host. Compare the host and port in normalized form instead of the raw origin string.

Update parseUrl’s host-boundary validation to compare the URL’s normalized
hostname and port, accepting explicit default ports such as :443 for HTTPS and
:80 for HTTP while still requiring one {key} after the host in an absolute
HTTP(S) URL.

Reject a bearer token on a plain http: settings URL.

parseUrl accepts http: URLs. storeApiInit then sends Authorization: Bearer on every request, so over plain HTTP a network observer on the path can read the token. The docs say to use an https: URL whenever a token is sent, but the code does not enforce it.

Consume or cancel the response body before the 404 return and the error throw.

The 404/204 branch returns, and the !res.ok branch throws, without reading or canceling res.body. Node's global fetch (undici) holds the connection until the body is consumed, canceled, or garbage collected. Repeated misses or API errors that return bodies can accumulate open connections.

Return 404 for a request equal to the prefix.

A request whose path equals the prefix, such as /static with prefix: '/static', or / with prefix: '/', strips to an empty key. The !filePath guard returns before the 404 branch, so the request gets the source's fallback response and its event continues through the chain. Answer 404 for an empty key when a prefix is set.

Suggested fix
-      if (!filePath) return;
+      if (!filePath) {
+        if (!prefix) return;
+        respond?.(notFound);
+        return false;

Correct the consent table: server flows skip denied events, not hold them.

The consent: { marketing: true } row says a denied event is "skipped and held in the destination's queue until the consent is granted." That holds only when consentDenied is 'queue', the web default. CLI-built server flows default to 'skip', which discards the event with no retained copy. The same row's last column already says skipped: consent. Scope the "held" clause to consentDenied: 'queue', or remove it.

The consent table in the CLI documentation incorrectly implies denied events are
always retained. Update the consent behavior description to clarify that events
are held in the destination queue only when consentDenied is 'queue', while CLI
server flows default to 'skip' and do not retain them; preserve the existing
consent-grant guidance.
