Old paths (index.js, dataService.js) remain as thin facades re-exporting from the new layout, so existing tests and downstream imports keep working — verified by 499 pre-existing tests still passing with the same 3 pre-existing failures. Layout: src/ transport/ fetch (network IO) sources/ slip44 parser domain/ relations, keywords (pure logic over indexed cache) store/ cache singleton, snapshot, indexer, queries services/ loader, rpcHealth, validation (orchestrators) http/ app.js buildApp (Fastify wiring + plugin order) routes/ one file per route domain util/ parseIntParam, sendError dataService.js: 1884 -> 29 lines (re-export facade) index.js: 549 -> 23 lines (CLI bootstrap + buildApp re-export) Adds 23 new unit tests covering the genuinely new helpers (parseIntParam, sendError) and direct-import contracts for the extracted modules (slip44, store/cache, domain/relations). Test totals: 522 pass / 3 pre-existing fail (was 499/3).

Updated the test to assert the throw rather than expecting the older forgiving return. - mcp-tools.test.js > handleToolCall > get_stats (x2): The vi.mock() factory was missing countChainsByTag, so handleGetStats was calling undefined and the handler wrapped it as result.isError. Added countChainsByTag to the mock with the same pure aggregation as the real implementation.

Data flows: live API first, falls back to a checked-in static JSON when l2beat.com is unreachable (their site is Cloudflare-gated and may 403 from some hosts/regions). The fallback keeps /scaling responsive even when the live fetch fails. New module layout: src/sources/l2beat.js fetchL2Beat() + normalizeL2BeatResponse() data/l2beat-fallback.json hand-curated last-known-good for top ~28 L2s src/http/routes/scaling.js GET /scaling, GET /scaling/:id Indexer changes: - new indexL2BeatSource() merges L2BEAT fields onto chains by chainId - auto-tags chains: L2 (always), ZK (ZK Rollup), Validium, Optimium - adds 'l2beat' to chain.sources - chain.l2Beat exposes: stage, category, stack, daLayer, hostChainId, purposes, tvs, tvsBreakdown, activity, links, riskView, milestones - per-chain dataFreshness flag ('live' | 'fallback' | 'unavailable') tells consumers whether values came from the API or the snapshot Cache + snapshot updated to persist l2beat raw response across restarts. transformChain() now surfaces the l2Beat field in /chains/:id and /scaling/:id responses. Defensive normalizer: - Tolerates 4 different payload shapes (projects array, data.projects, bare array, etc.) since L2BEAT's site contract is undocumented. - Drops projects without slug+chainId rather than emitting bad rows. - Optional-chains every nested field (stage, daLayer, tvs, tvsBreakdown). Tests: +18 new (sources/l2beat.test.js, store/indexer-l2beat.test.js). Suite: 543 passing / 0 failing / 4 skipped (was 525/0/4).

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a background refresher that re-fetches L2BEAT data on an interval (default 5 min via L2BEAT_REFRESH_INTERVAL_MS) and re-merges into the indexed cache. Replaces "loaded once at startup" with continuous freshness. Design: - runL2BeatRefresh() — fetch + race-guarded merge. Skips writing if cachedData.lastUpdated changed mid-flight (i.e. a concurrent loadData() ran), preventing stale-data overwrites. - startL2BeatRefresh() — kick off immediately, then setInterval. Idempotent (second call is a no-op). Uses .unref() so the timer never blocks process exit. Self-coalescing: if a refresh is in flight when the timer fires, the next tick is queued instead of running parallel. - stopL2BeatRefresh() — for tests / clean shutdown. - getL2BeatRefreshStatus() — exposes isRefreshing, lastRefreshAt, lastRefreshSource, lastRefreshError, lastRefreshProjectCount, intervalMs. Wiring: - buildApp starts the refresher right after initializeDataOnStartup (alongside startRpcHealthCheck), and on every successful background refresh from the stale-first startup path. - indexer.js exports indexL2BeatSource so the refresher can re-merge without rebuilding the entire index. - New endpoint GET /scaling/status surfaces refresher state. - /scaling response now includes a `refresher` object with the same status block, so consumers can tell whether the data is fresh. Tests: +6 (services/l2beatRefresher.test.js) — covers the no-data skip, successful merge, race-guard skip, fetch-error path, status accessor, and start-twice idempotency. index.test.js: stubs the refresher module so buildApp doesn't kick off a real network fetch in unit tests.

charset=UTF-8 Content-Transfer-Encoding: 8bit Now that L2BEAT data flows in, /validate cross-checks it against the other sources. Five new rules surface real data quality issues: rule 7 l2beat_missing_classification L2BEAT classifies the chain but no l2Of/testnetOf relation from theGraph or chains confirms it — upstream registries may be stale or this is a new L2 they haven't picked up yet. rule 8 l2beat_hostchain_no_relation L2BEAT says hostChainId=N but the chain has no l2Of/testnetOf relation pointing to N — settlement-chain disagreement. rule 9 l2beat_category_name_mismatch L2BEAT category contradicts the chain name (e.g. "ZK Rollup" for something named "Optimistic ..."). rule 10 l2beat_unknown_chains (global, not per-chain) L2BEAT lists a chainId we don't have in our registry — discoverability gap, new L2 worth adding upstream. rule 11 l2beat_stage_zero_high_tvs Stage 0 chain with TVS > $1B — risk signal worth surfacing (informational, not strictly a data error). Each rule appears in the existing /validate response shape under errorsByRule.ruleN_* and summary.ruleN. No breaking changes to the existing 6 rules. Rules 7-9 + 11 are per-chain (inside validateChain); rule 10 is global (iterates cachedData.l2beat.projects to catch chains not in indexed.byChainId). Tests: +14 covering each rule's positive case, the no-flag negative cases, and aggregate summary structure. validation.test.js moves the validation suite under tests/unit/services/ matching the new src/ layout (pre-existing dataService.test.js coverage of validateChainData untouched). Suite: 563 passing / 0 failing / 4 skipped (was 549/0/4). --- src/services/validation.js | 142 +++++++++++++- tests/unit/services/validation.test.js | 258 +++++++++++++++++++++++++ 2 files changed, 398 insertions(+), 2 deletions(-) create mode 100644 tests/unit/services/validation.test.js diff --git a/src/services/validation.js b/src/services/validation.js index cae3f9e..1d86300 100644 --- a/src/services/validation.js +++ b/src/services/validation.js @@ -183,6 +183,127 @@ function validateRule6GoerliDeprecated(chain, statuses, errors) { } } +function validateRule7L2BeatMissingClassification(chain, errors) { + if (!chain.l2Beat) return; + + // L2BEAT classifies the chain as a scaling solution.

charset=UTF-8 Content-Transfer-Encoding: 8bit Rounds out /validate with five more cross-source checks. Complements the L2BEAT rules (7-11) from the previous commit by reaching into the other sources (theGraph vs chains.json vs chainlist vs slip44 vs rpcHealth). rule 12 rpc_block_height_drift Two or more working RPC endpoints for the same chain report block heights >100 apart. Surfaces stuck/forked nodes that respond to web3_clientVersion + eth_blockNumber but lag the consensus tip. Threshold is hard-coded; lift to config later if tuning is needed. rule 13 name_disagreement chains.json name and theGraph fullName don't match after normalization (lowercase, strip "mainnet", strip non-alnum, skip substring relationships). Catches typos and outdated names while tolerating "Arbitrum One" vs "Arbitrum"-style variants. rule 14 native_currency_mismatch chains.json nativeCurrency.symbol disagrees with theGraph's nativeToken (case-insensitive). rule 15 slip44_native_symbol_mismatch Chain has slip44Info but its symbol doesn't match the nativeCurrency.symbol — usually means the chain is using a slip44 coinType that doesn't actually belong to it. rule 16 rpc_url_in_one_source_only A healthy RPC URL appears in chainlist but not chains.json (or vice versa). Strong hint that one source is stale and needs updating upstream. Only fires when the chain is in both sources AND the URL is currently passing health checks in rpcHealth. Slots into the existing /validate response shape. errorsByRule gets 5 new keys (rule12..rule16); summary gets 5 new counts. No breaking changes to rules 1-11. Tests: +13 covering each rule's positive case + negative cases. Updated the seedCache helper to accept rawChains/rawChainlist/rpcHealth so rules 12 and 16 can be exercised in isolation. Suite: 576 passing / 0 failing / 4 skipped (was 563/0/4). /validate now has 16 cross-source rules covering theGraph, chainlist, chains, slip44, l2beat, and rpcHealth. --- src/services/validation.js | 179 +++++++++++++++++- tests/unit/services/validation.test.js | 245 ++++++++++++++++++++++++- 2 files changed, 413 insertions(+), 11 deletions(-) diff --git a/src/services/validation.js b/src/services/validation.js index 1d86300..a90251c 100644 --- a/src/services/validation.js +++ b/src/services/validation.js @@ -304,6 +304,166 @@ function validateRule10L2BeatUnknownChains(errors) { } } +const RPC_BLOCK_HEIGHT_DRIFT_THRESHOLD = 100;

charset=UTF-8 Content-Transfer-Encoding: 8bit Seven independent fixes for issues surfaced in PR review. Each is verified by an existing or new test. #2 indexer doesn't retain chain.slip44 (bug) indexChainsSource and mergeChainlistEntry now keep the slip44 field from raw sources, so attachSlip44Info can actually populate chain.slip44Info. New regression test verifies the round-trip. #3,#9 SLIP-44 fetch failure indistinguishable from empty success (bug) loader.js now only calls parseSLIP44 when slip44Text isn't null, preserving null end-to-end through applyDataToCache and the snapshot round-trip. /sources will now correctly report slip44: 'not loaded' when the fetch failed (was always 'loaded' because {} is truthy). #8,#11 Starknet fallback chainId exceeds Number.MAX_SAFE_INTEGER (bug) Removed the Starknet entry (chainId 23448594291968334) from data/l2beat-fallback.json. The codebase treats chainId as a JS Number for object keys, parseIntParam, and comparisons, so a chainId beyond 2^53-1 would round and cause silent mis-lookups. Documented in the file's note field; the live API can still surface Starknet once the indexer learns to handle BigInt IDs. #12 L2BEAT stale data persists across refreshes (bug) indexL2BeatSource now clears chain.l2Beat and removes 'l2beat' from chain.sources for any chain whose chainId isn't in the fresh project list. Defensive: only clears when the new list is non-empty, so a transient unavailable fetch doesn't wipe known data. New regression test exercises a refresh with a dropped project. #1 /export had no rate limit (CodeQL: missing-rate-limiting) Wrapped /export with the same RELOAD_RATE_LIMIT_MAX config as /reload (both are I/O-heavy and previously unguarded). #5,#10 fetchData returned undefined for unknown format (contract bug) Added an explicit `return null` in the format-fallthrough branch with a logged error, matching the documented "returns null on failure" contract. New tests cover both the success and unknown-format paths. #6 "All data sources failed" error message misleading Renamed to "All core data sources failed" since L2BEAT is intentionally excluded from loadedSourceCount (it has its own static fallback and isn't useful without the core sources). Both existing test assertions updated. #7 scaling.js comment mentioned non-existent 'unavailable' freshness Updated to reflect actual runtime: only 'live' and 'fallback' ever appear in chain.l2Beat.dataFreshness. Chains the merge couldn't reach simply have no l2Beat field. Skipped (per triage): #4 duplicate RPC sweep on warm start — minor wastefulness, not user-visible; deferred.

This makes /health a real readiness probe: GET /health now returns: status: 'ok' | 'degraded' | 'down' - down when any core source (theGraph/chainlist/chains) is missing - degraded when supplementary sources (slip44 null, l2beat empty) are missing, or a refresher hasn't run within 2x its expected interval - ok otherwise sources: theGraph/chainlist/chains/slip44/l2beat each report { loaded: bool, ageSeconds: number|null, source?: 'live'|'fallback'|null } refreshers: rpc: { isRunning, lastRunAt } l2beat: full status block from getL2BeatRefreshStatus() plus the existing dataLoaded, lastUpdated, totalChains. GET /sources extended: - Now reports slip44: 'not loaded' when slip44 is null (was always 'loaded' because {} is truthy — same fix as the SLIP-44 failure preservation work). - Adds l2beat: 'loaded'|'not loaded' based on whether projects[] is non-empty. Implementation notes: - Single sourceFreshness(cache) helper computes per-source loaded/age. - deriveOverallStatus() folds sources + refreshers into the verdict. - ageSeconds() returns null for null/invalid timestamps (no NaN values leak into the response). - All null/undefined checks use loose equality (!= null) to be tolerant of mocks that omit the l2beat field. Tests: +6 in http/admin.test.js covering ok/degraded/down verdicts and the SLIP-44 null preservation. Integration test mock updated to include the new l2beat field so the existing /health "should return ok" assertion still holds.

charset=UTF-8 Content-Transfer-Encoding: 8bit Routes now declare their query/param shapes via Fastify's schema option, so Ajv catches type errors, enum violations, max-length overruns, and — critically — unknown query parameters that previously silently 200'd. Coverage: /chains ?tag enum (Testnet/L2/Beacon/ZK/Validium/Optimium) additionalProperties:false (typo catcher) /chains/:id :id must match ^-?\\d+$ /search ?q required, 1..MAX_SEARCH_QUERY_LENGTH chars additionalProperties:false /relations/:id :id pattern /relations/:id/graph ?depth integer 1..5, additionalProperties:false /endpoints/:id :id pattern /slip44/:coinType :coinType pattern /rpc-monitor/:id :id pattern /scaling/:id :id pattern Implementation: - buildApp wires a `schemaErrorFormatter` that translates Ajv errors into the project's `{ error: "..." }` envelope, preserving the existing user-friendly wording ("Invalid chain ID", "Invalid tag. Allowed: ...", "Query too long. Max length: ...", "Invalid depth. Must be between 1 and 5"). Field-name → noun mapping handles cases like `:id` → "chain ID" and `:coinType` → "coin type". - `setErrorHandler` ensures every 4xx/5xx response uses the same envelope (not just validation errors). - Ajv configured with `removeAdditional: false` so additionalProperties actually rejects unknown params instead of silently stripping them. This is the typo-catcher win: `GET /chains?tags=L2` (typo of `?tag=`) now returns 400 instead of returning all chains. Tests: +1 integration test for the unknown-query-parameter rejection. All 12 existing 400-response tests still pass — the schema-driven messages are byte-compatible with the previous handler-driven ones.

Structured logging via pino - All 25 console.{log,warn,error} calls in src/ replaced with pino-backed logger.{info,warn,error}. - New src/util/logger.js exports a shared logger with structured fields (component='chains-api'). Level controlled via LOG_LEVEL env. - Fastify already uses pino internally; this brings background jobs (sources, services, store) onto the same logger so a single log pipeline captures everything. - JSON output by default; pretty in TTY when running locally. 2. GET /metrics endpoint (Prometheus exposition format) - New src/util/metrics.js: tiny zero-dep counter + gauge implementation in <90 lines. Counters tracked in-memory and incremented from transport/services. Gauges computed on scrape from live cache. - Metrics: chains_api_source_fetch_total{url, outcome} counter chains_api_refresh_total{refresher, outcome} counter chains_api_rpc_check_total{outcome} counter chains_api_chains_total gauge chains_api_source_loaded{source} gauge chains_api_data_age_seconds gauge chains_api_l2beat_refresh_age_seconds gauge chains_api_rpc_check_age_seconds gauge chains_api_validation_errors{rule} gauge - Content-Type: text/plain; version=0.0.4 (Prometheus default). - Validation summary computed on scrape (O(N chains) — fine for scrape intervals >= 15s; can be cached if it becomes a problem). Tests: +6 in http/metrics.test.js covering content-type, gauges (loaded sources, total chains), counters (with labels), and validation error labels. Updated 5 RPC-health tests in dataService.test.js to spy on the new pino logger instead of console.{log,warn}. Pattern: spy on logger.warn / logger.info after the module loads. For the vi.resetModules() test we re-import logger.js after reset so the fresh module is the one being spied on. Suite: 595 passing / 0 failing / 4 skipped (was 589/0/4). Note: index.js still has a few console.error calls in the CLI bootstrap path — those run before pino is configured, so they stay as-is. --- src/http/app.js | 2 + src/http/routes/metrics.js | 34 ++++++++++ src/http/routes/root.js | 3 +- src/services/l2beatRefresher.js | 18 ++++-- src/services/loader.js | 15 ++--- src/services/rpcHealth.js | 17 +++-- src/sources/l2beat.js | 7 ++- src/store/snapshot.js | 7 ++- src/transport/fetch.js | 18 ++++-- src/util/logger.js | 14 +++++ src/util/metrics.js | 107 ++++++++++++++++++++++++++++++++ tests/unit/dataService.test.js | 36 +++++------ tests/unit/http/metrics.test.js | 104 +++++++++++++++++++++++++++++++ 13 files changed, 335 insertions(+), 47 deletions(-) create mode 100644 src/http/routes/metrics.js create mode 100644 src/util/logger.js create mode 100644 src/util/metrics.js create mode 100644 tests/unit/http/metrics.test.js diff --git a/src/http/app.js b/src/http/app.js index 4487995..91319b5 100644 --- a/src/http/app.js +++ b/src/http/app.js @@ -21,6 +21,7 @@ import { slip44Routes } from './routes/slip44.js'; import { rpcMonitorRoutes } from './routes/rpcMonitor.js'; import { scalingRoutes } from './routes/scaling.js'; import { adminRoutes } from './routes/admin.js'; +import { metricsRoute } from './routes/metrics.js'; import { rootRoute } from './routes/root.js'; function resolveCorsOrigin(value) { @@ -171,6 +172,7 @@ export async function buildApp(options = {}) { await fastify.register(slip44Routes); await fastify.register(rpcMonitorRoutes); await fastify.register(scalingRoutes); + await fastify.register(metricsRoute); await fastify.register(rootRoute); return fastify; diff --git a/src/http/routes/metrics.js b/src/http/routes/metrics.js new file mode 100644 index 0000000..fe8cc7b --- /dev/null +++ b/src/http/routes/metrics.js @@ -0,0 +1,34 @@ +import { + getCachedData, + getRpcMonitoringStatus, + validateChainData +} from '../../../dataService.js'; +import { getL2BeatRefreshStatus } from '../../services/l2beatRefresher.js'; +import { renderMetrics } from '../../util/metrics.js'; + +/** + * GET /metrics — Prometheus exposition format.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the two parallel setInterval schedulers in services/rpcHealth.js and services/l2beatRefresher.js with a single queue-based loop in src/services/chainRefresher.js. The thundering-herd RPC sweep becomes a rolling per-chain check spread across the sweep window. Design: queue = [ { type: 'l2beat_batch' }, // 1 job { type: 'chain_rpc', chainId: N }, ... one per chain ] every SWEEP_TICK_MS (default 1s, env-tunable): if queue empty: rebuild from current indexed chains, increment sweep# pop next job, dispatch to processor Job processors live in chainRefresher.js: - processL2BeatBatch() fetch + race-guarded indexL2BeatSource merge - processChainRpc(id) check every RPC for one chain, race-guarded writes to cachedData.rpcHealth[id] AND stamps chain.lastTested for per-chain freshness Why rolling: - Old all-at-once sweep: ~3000 RPC URLs hit in parallel (capped at 8 concurrent). Worst case spikes outbound load. - New rolling: ~10 RPC URLs/sec average (one chain/tick × ~10 URLs/chain typical). Smooth, predictable, gentle on upstream RPCs. - L2BEAT batch lands as job #0 of every sweep, so its cadence matches the RPC sweep (~5 min for 300 chains at 1s/tick) without a separate setInterval. Backwards compatibility: services/rpcHealth.js becomes a thin shim: - runRpcHealthCheck() drains every chain immediately (legacy blocking contract; used by /reload and tests). Detects "no endpoints" and emits the same warn line. - startRpcHealthCheck() alias for startChainRefresher() - getRpcMonitoringStatus() reads from chainRefresher services/l2beatRefresher.js similarly: - runL2BeatRefresh() delegates to processL2BeatBatch - startL2BeatRefresh() alias for startChainRefresher - getL2BeatRefreshStatus() reads from chainRefresher buildApp wiring unchanged: it still calls startRpcHealthCheck() and startL2BeatRefresh(). Both now start the same loop; the second call is a no-op (idempotent). New endpoint: GET /refresher exposes the unified status: tickIntervalMs, isTickInFlight, lastTickAt, lastTickJobType, queueDepth, sweep { jobIndex, totalJobs, sweepNumber, sweepStartedAt }, l2beat { lastRefreshAt, lastRefreshSource, lastRefreshProjectCount, lastRefreshError, intervalMs }, rpc { isMonitoring, lastSweepCompletedAt, endpointsCheckedThisSweep } Tests: +11 new in services/chainRefresher.test.js covering the two job processors, tick scheduling, sweep queue rebuild, overlap guard, and status accessor. Updated services/l2beatRefresher.test.js config mock to include the RPC-related env vars that chainRefresher transitively requires.

charset=UTF-8 Content-Transfer-Encoding: 8bit Eight follow-ups from the PR review. Each is independent of the others and could land separately; bundled here for review economy. 1. Logging migration completion fetchUtil.js (3 calls) and mcp-server-http.js (10 calls) now use the shared pino logger. index.js CLI bootstrap stays on console.error because it runs before pino is configured. 2. Dead config marked @deprecated - RPC_CHECK_CONCURRENCY no longer drives anything since the unified rolling refresher (one chain per tick). - L2BEAT_REFRESH_INTERVAL_MS no longer drives scheduling; only kept as a hint in /scaling/status. JSDoc warns callers in both cases. 3. dataService.js facade comment Explicitly documents that new code should import directly from src/ and not add new exports here. 4. 5xx error sanitization setErrorHandler now returns "Internal Server Error" for 5xx instead of leaking error.message. Server-side log still records the full error via fastify.log.error. 5. /metrics validation cache (30s) validateChainData is O(N chains × M rules); cache the summary result for VALIDATION_CACHE_MS so frequent Prometheus scrapes don't re-run validation on every request. 6. getAllChains() memoization Caches the transformChain'd array, invalidated by cachedData.lastUpdated AND by cachedData.l2beat.fetchedAt (so a rolling L2BEAT refresh correctly invalidates without a full data reload). Reduces hot-path work on /chains, /scaling, /stats, and the validation pass. 7. Inter-job race guard in chainRefresher Each sweep captures cachedData.lastUpdated at start. If a concurrent loadData() bumps it mid-sweep, the rest of the queue is dropped to prevent writing a frankensweep of mixed data versions. Logs a warn with the dropped job count. 8. Documentation - validation.js rule 13 marked as heuristic + carries severity: 'info' in error objects (advisory, not authoritative). - scaling.js route header documents the Starknet chainId precision gap (CAIP-2 numeric ID 0x534e5f4d41494e exceeds Number.MAX_SAFE_INTEGER). New tests (+4): /health exposes per-source freshness and per-refresher status /refresher returns the unified refresher status block /metrics returns Prometheus exposition with text/plain content type /metrics includes source-loaded gauge for each of the 5 sources New workflow: .github/workflows/refresh-l2beat-fallback.yml — weekly cron + manual dispatch that fetches the live L2BEAT API, normalizes via the same module as runtime, filters non-safe-integer chainIds, and opens a PR if data/l2beat-fallback.json differs. Gracefully skips when the live API is unreachable. PR title updated from the misleading "Ignore graphify-out/ knowledge graph artifacts" to "Architectural refactor + L2BEAT integration + observability" with an accurate body via the GitHub MCP API.

Replace FIELD_NOUNS map with ajv-errors per-schema errorMessage The hard-coded `id → "chain ID"` / `coinType → "coin type"` mapping in formatSchemaValidationError() was brittle: adding a new route with a different param name would silently fall through to a generic message. Now each schema declares its own user-facing wording via the `errorMessage` keyword (ajv-errors). The route author controls the message at the schema; no central registry to maintain. - Added `ajv-errors` dependency and registered it as an Ajv plugin in buildApp() with `allErrors: true` so the plugin can inspect every violation. - schemaErrorFormatter prefers `errorMessage`-authored strings; for `additionalProperties` it still interpolates the property name server-side (the schema can't do `${...}` interpolation). - Migrated every schema in src/http/routes/*.js to carry its own errorMessage. The 12 existing 400-response tests pass unchanged. 2. ESLint with no-restricted-imports gating dataService.js First ESLint config in the repo. Minimal flat config (eslint v10). The rule applies to `src/{store,domain,sources,services,transport,util}/` and prevents those layers from importing the legacy `dataService.js` facade — they must depend on peer modules under src/ directly, which keeps the layered architecture acyclic. src/http/ is intentionally exempt: routes are the HTTP boundary and the integration tests mock `dataService.js` as a single seam. Moving those mocks to per-module paths is a separate test refactor. - `npm run lint` runs `eslint src/`. - .github/workflows/docker-build.yml now runs lint before tests. Suite: 610 passing / 0 failing / 4 skipped (unchanged).

Routes now import from their actual peer modules under src/ instead of going through the legacy dataService.js facade, and the ESLint rule covers the entire src/ tree (was previously narrowed to src/{store,domain,sources,services,transport,util}/ to dodge the test refactor). Test refactor: tests/integration/api.test.js — replaces the single vi.mock('../../dataService.js', ...) with vi.hoisted() shared mock fns wired into 7 vi.mock factories (one per src/ module the routes use). Test bodies that reference `dataService.X` keep working because dataService.js's re-exports resolve to the same hoisted fn identities via the mocked src/ modules. tests/unit/http/admin.test.js — now mocks each src/ path individually. tests/unit/http/metrics.test.js — same. tests/unit/index.test.js — same; the onBackgroundRefreshSuccess capture pattern moved from `dataService.startRpcHealthCheck` to a direct hoisted mock reference. Route migrations: src/http/app.js initializeDataOnStartup → ../services/loader.js startRpcHealthCheck → ../services/rpcHealth.js src/http/routes/chains.js → ../../store/queries.js src/http/routes/relations.js → ../../domain/relations.js src/http/routes/endpoints.js → ../../store/queries.js src/http/routes/slip44.js → ../../store/cache.js src/http/routes/scaling.js → ../../store/queries.js src/http/routes/rpcMonitor.js → ../../store/queries.js + services/rpcHealth.js src/http/routes/metrics.js → store/cache + services/{rpcHealth,validation,l2beatRefresher} src/http/routes/admin.js → store/{cache,queries} + domain/keywords + services/{loader,rpcHealth,validation,l2beatRefresher} ESLint scope: Rule applies to all of src/**/*.js (was narrowed to non-http subtrees). dataService.js is now reserved exclusively for legacy external callers; new code under src/ depends on peer modules directly.

charset=UTF-8 Content-Transfer-Encoding: 8bit The HTTP layer added /scaling, /scaling/:id, and /refresher in earlier commits; MCP clients had no parallel surface and were forced to read the new chain.l2Beat field out of get_chain_by_id responses. Three new tools fix that: get_scaling_chains Returns chains classified by L2BEAT as scaling solutions, plus the refresher status block so callers can tell whether the data is live or from the static fallback snapshot. Parallels GET /scaling. get_l2beat_by_id { chainId } Single chain's L2BEAT view. Returns errorResponse when the chain isn't in the registry, when it has no L2BEAT classification, or when chainId is invalid. Parallels GET /scaling/:id. get_refresher_status Exposes the unified rolling refresher's freshness state. Parallels GET /refresher (lighter surface — just the L2BEAT-relevant fields). mcp-tools.js now imports getL2BeatRefreshStatus directly from src/services/l2beatRefresher.js since the facade doesn't re-export it. Tests: +7 covering both happy and error paths for each tool, plus a sanity check that getToolDefinitions() exposes the new names. Tool count assertion bumped 13 → 16.

charset=UTF-8 Content-Transfer-Encoding: 8bit Deploy & dependency fixes - package.json: declare pino directly (previously only transitive via fastify). - Dockerfile: COPY src/, data/, public/ so the refactored layout actually ships in the container. Correctness fixes - src/services/loader.js: exclude SLIP-0044 from the "at least one source loaded" guard. SLIP-0044 contributes coin-type metadata but no chain entries, so the API was previously coming up with an empty index when every chain registry failed but SLIP-44 succeeded. Error message reworded accordingly. - src/services/rpcHealth.js: in runRpcHealthCheck, check the data version before each chain iteration so a concurrent loadData() aborts the sweep immediately instead of leaking partial old-version results into the fresh cache. - src/services/chainRefresher.js: apply MAX_ENDPOINTS_PER_CHAIN in processChainRpc so large chain entries can't generate per-tick request bursts that ignore the configured cap. - src/transport/fetch.js: validate format before issuing any I/O so unsupported callers fail deterministically without a wasted outbound request; move the success counter increment after the body parse so a single body-parse failure isn't double-counted as both success and error. - src/store/indexer.js: indexL2BeatSource no longer early-returns on an empty project list — it runs the stale-data cleanup pass even when the fresh L2BEAT payload is empty, so /scaling stops serving projects that have disappeared. Tag cleanup widened to also remove L2BEAT-derived tags (L2, ZK, Validium, Optimium). Project chainIds are normalized to numbers up front so byChainId lookups and freshChainIds membership checks use one type. - src/sources/l2beat.js: extractChainId coerces strings ("8453") and CAIP-2 strings ("eip155:8453") to safe integers; unsafe values (>= 2^53 or non-numeric) become null so downstream indexing stays consistent. Security - src/util/metrics.js: Prometheus label values now escape backslashes (and newlines) in addition to double quotes. Same escape applied to the dynamic rule label in chains_api_validation_errors. Test fixes - tests/unit/services/chainRefresher.test.js: add MAX_ENDPOINTS_PER_CHAIN to the config mock so the new cap import resolves. - tests/unit/dataService.test.js: add MAX_ENDPOINTS_PER_CHAIN to the config mock; loadData tests now use non-null mock payloads since SLIP-44 no longer satisfies the chain-source guard on its own; update the error-message assertions to match the reworded "All chain registry sources failed" text. All 618 tests pass, 0 failures, 4 skipped (was 0 failed pre-fixes). --- Dockerfile | 3 +++ package-lock.json | 3 ++- package.json | 3 ++- src/services/chainRefresher.js | 10 +++++-- src/services/loader.js | 16 ++++++----- src/services/rpcHealth.js | 7 +++++ src/sources/l2beat.js | 26 +++++++++++++++--- src/store/indexer.js | 31 +++++++++++++++++----- src/transport/fetch.js | 27 ++++++++++--------- src/util/metrics.js | 17 ++++++++++-- tests/unit/dataService.test.js | 23 ++++++++-------- tests/unit/services/chainRefresher.test.js | 1 + 12 files changed, 122 insertions(+), 45 deletions(-) diff --git a/Dockerfile b/Dockerfile index 9077fd0..fd6b684 100644 --- a/Dockerfile +++ b/Dockerfile @@ -15,6 +15,9 @@ RUN npm ci --only=production # Copy application files COPY *.js ./ +COPY src/ ./src/ +COPY data/ ./data/ +COPY public/ ./public/ # Ensure app owns the working directory RUN chown -R app:app /app diff --git a/package-lock.json b/package-lock.json index 24ffb5f..70ad070 100644 --- a/package-lock.json +++ b/package-lock.json @@ -17,7 +17,8 @@ "ajv-errors": "^3.0.0", "express": "^5.2.1", "fastify": "^5.8.1", - "https-proxy-agent": "^7.0.6" + "https-proxy-agent": "^7.0.6", + "pino": "^10.3.0" }, "bin": { "chains-api-mcp": "mcp-server.js", diff --git a/package.json b/package.json index 1725a9e..b7ee78e 100644 --- a/package.json +++ b/package.json @@ -41,7 +41,8 @@ "ajv-errors": "^3.0.0", "express": "^5.2.1", "fastify": "^5.8.1", - "https-proxy-agent": "^7.0.6" + "https-proxy-agent": "^7.0.6", + "pino": "^10.3.0" }, "devDependencies": { "@fast-check/vitest": "^0.2.4", diff --git a/src/services/chainRefresher.js b/src/services/chainRefresher.js index 8c6a7c2..80064c2 100644 --- a/src/services/chainRefresher.js +++ b/src/services/chainRefresher.js @@ -24,7 +24,8 @@ import { jsonRpcCall } from '../../rpcUtil.js'; import { RPC_CHECK_TIMEOUT_MS, - L2BEAT_REFRESH_INTERVAL_MS + L2BEAT_REFRESH_INTERVAL_MS, + MAX_ENDPOINTS_PER_CHAIN } from '../../config.js'; import { logger } from '../util/logger.js'; import { incCounter } from '../util/metrics.js'; @@ -124,7 +125,12 @@ export async function processChainRpc(chainId) { const dataVersion = cachedData.lastUpdated; const normalized = (chain.rpc || []).map(normalizeRpcUrl).filter(Boolean); - const urls = Array.from(new Set(normalized)).filter(u => u.startsWith('http')); + // Dedupe, keep only HTTP(S), then cap per-chain fan-out so large chain + // entries don't create per-tick request bursts that ignore the configured + // MAX_ENDPOINTS_PER_CHAIN ceiling. + const urls = Array.from(new Set(normalized)) + .filter(u => u.startsWith('http')) + .slice(0, MAX_ENDPOINTS_PER_CHAIN); if (urls.length === 0) return; rpcState.isMonitoring = true; diff --git a/src/services/loader.js b/src/services/loader.js index 627255f..c4e4e0f 100644 --- a/src/services/loader.js +++ b/src/services/loader.js @@ -27,12 +27,18 @@ let dataRefreshPromise = null; let startupInitializationPromise = null; let startupInitialized = false; -function countLoadedSources(data) { +/** + * Count how many of the three chain registries (theGraph, chainlist, chains) + * loaded successfully.
