feat(n8n): rebuild the nodes on n8n's HTTP helper so the package passes n8n verification - #159
Merged

Conversation
The Vehicle and Energy nodes no longer bundle @teslemetry/api. A node-local teslemetryRequest() sends each request through this.helpers.httpRequestWithAuthentication with the package's credential and maps failures to NodeApiError with the API's text and status. Sources move to n8n's standard nodes/<Node>/ and credentials/ layout, which n8n's lint and scanner read. Operations are grouped by resource, labels follow n8n's lint rules, and every output item carries pairedItem. The SSE Trigger is removed here and rebuilt as a polling trigger in the next commit.
n8n Cloud forbids the long-lived reconnecting stream the SDK's SSE client
needs (timers, events, global fetch), and emulating it with hidden timers would
evade n8n's check. The trigger now uses n8n's poll() helper on the Poll Times
schedule and emits only values that changed since the previous check.
Vehicle events read GET /api/1/vehicles/{vin}/telemetry, the cached telemetry
snapshot: it never wakes the car and costs no credits. Energy events read
live_status or site_info, which Teslemetry serves from its own cache. A null
tariff_content_v2 is reported as a tariff removal.
Not carried over: the stream-only Credits, Config and Energy Totals events, and
watching all vehicles or all sites at once.
README describes the resources and the polling trigger (interval, cached reads, credit cost, dropped events). The add-command skill and AGENTS.md no longer say the n8n package uses @teslemetry/api. Changeset: minor.

n8n's title-case lint turned 'HH:mm' into 'HH:Mm', which reads as month. The format now sits in the placeholder and the description.

@teslemetry/n8n-nodes-teslemetryon n8n's own helpers so the package can pass n8n's verification scanner. The package no longer bundles or depends on@teslemetry/api. No other package changes.this.helpers.httpRequestWithAuthenticationwith the package'steslemetryApicredential (Bearer header). A node-localteslemetryRequest()innodes/shared.tssets the base URLhttps://api.teslemetry.com, sends the request withignoreHttpStatusErrors, and maps a non-2xx answer toNodeApiErrorwith the API's own text and HTTP status. Each operation is a small table entry with the same path and body the SDK sent; the existing per-operation tests still assert them.src/to n8n's standardnodes/<Node>/<Node>.node.tsandcredentials/. n8n's lint and the scanner read only that layout (theno-credential-reuseerrors came fromsrc/).no-case-declarations,no-explicit-any,missing-paired-item,node-connection-type-literal,no-credential-reuse,require-node-description-fields,icon-validation,node-usable-as-tool,cred-class-field-icon-missing, plus the option-ordering and label-casing rules that apply once sources are innodes/.@n8n/scan-community-package@0.40.0, plugin 0.37.0) makesresource-operation-patternan error (the repo's node-cli 0.51.5 still reports it as a warning). Vehicle operations are now grouped as Vehicle, Doors and Closure, Climate, Charging; Energy as Status, Setting. Operation values are unchanged andexecute()dispatches on the operation alone, so saved workflows keep running. A saved node whose operation is outside the default resource may need its resource picked again in the editor.No timers,
events, globalfetch,globalThisorconsoleremain: a grep of the packeddist/finds none, and nothing is aliased or hidden.Trigger decision: polling, not dropped
n8n Cloud forbids the long-lived reconnecting SSE stream (timers +
events+fetch), and emulating it with hidden timers would evade the check. The Trigger is now a polling trigger (polling: true,poll()), run on n8n's standard Poll Times schedule (default: every minute). It records a baseline on the first check after activation and then emits one item per changed value; a manual test run returns the current values.GET /api/1/vehicles/{vin}/telemetry, the cached Fleet Telemetry snapshot. Per the API spec this read never wakes the car, never calls Tesla and costs no credits. Events kept: Any Change, Data (changed fields only), Signal (one field), State, Connectivity, Alerts, Errors, Vehicle Data.live_status(Teslemetry cache refreshed about every 30 s) orsite_info(about every 5 min). Events kept: Live Status, Site Info, Tariff Content.tariff_content_v2: nullis emitted as a tariff removal; an absent field emits nothing.I chose polling over dropping the trigger because the cached telemetry endpoint gives the same data topics the stream carried, at no credit cost, so the main use (start a workflow when a vehicle value changes) still works, with the poll interval as latency.
Proof
Scanner.
npx @n8n/scan-community-packageonly scans versions already published to npm. I ran its own lint stage (analyzePackagefromscanner/scanner.mjs, v0.40.0) on the packed tarball (**/*.{js,ts,json}) and on the package source with the scanner'sSOURCE_FILE_PATTERNS(the provenance-source step):Before this PR, 0.5.1 failed with 23 errors, all in the bundled SDK chunk. The provenance step runs only after publish.
Linter (
pnpm --filter @teslemetry/n8n-nodes-teslemetry validate=n8n-node lintv0.51.5): before this PR 52 errors and 5 warnings; now:The 4 warnings are
icon-prefer-themed-variants(single-file icons; light/dark variants are optional).Tests:
pnpm --filter @teslemetry/n8n-nodes-teslemetry testthrough testgate, 119 pass, 0 fail. The tests now answer through a fakehttpRequestWithAuthenticationin place of a mocked globalfetch. The SSE tests are replaced by polling tests (baseline, changed fields only, Any Change, Signal, manual run, subject change, energy live status, tariff removal, API failure without the credential).Load check:
verify:packagepacks the tarball and loads it with n8n'sPackageDirectoryLoader: 3 nodes and 1 credential.Live check: the built nodes driven through n8n-core's real
httpRequest(axios) against the live API:Risks and open points
na/eu.teslemetry.comfrom thex-regionheader. These nodes always callapi.teslemetry.com, the same host the credential test already uses.live_status/site_infocost no credits and only fresh fetches from Tesla do. That statement comes from the task brief; the API spec documents the caching, but not the billing.
