protomap-test-javascript

A synthetic code base of the fictional company Acme for testing ProtoMap: 180 gRPC services with 1397 methods in 12 domains, and 5097 protobuf messages with 22163 fields, many nested several levels deep.

It was generated, with the eight other protomap-test-* repositories, from one catalog of Acme's APIs. The repositories own disjoint domains and call each other's services, so each holds copies of the protobuf files it needs from the others, byte for byte as their owners have them.

Layout

Acme Live sells and runs live events: venues, shows, tickets, seating, the box office, admissions, and more. The code is plain CommonJS JavaScript for Node.js 22 or newer, with no build step: @grpc/proto-loader loads the protobuf files under proto/ at startup, so there are no generated bindings, and messages are plain objects with the fields' own snake_case names. src/domains/ holds each team's handlers and operations, written as handler modules over operation modules, as service classes, or as handler factories; src/platform/ holds the clients, the promise and stream adapters over grpc-js, request context, the PostgreSQL store, and an EventEmitter work bus. src/server/main.js registers every service behind an identity interceptor and starts the workers; src/jobs/ and src/admin/ hold batch jobs and operator commands. Use pnpm 12.14.0: pnpm install, pnpm check, and pnpm test. Set DATABASE_URL, run pnpm migrate, and set GRPC_MESH, GRPC_LISTEN, and the service credential ACME_SERVICE_TOKEN before pnpm start. Only work-bus handoffs are marked as known gaps in the oracle.

The domains are fanportal, venues, shows, ticketing, seating, boxoffice, performers, tours, admissions, concessions, sponsorships, broadcasts. It calls services of accounting, analytics, anomalies, assets, audit, authorization, benefits, billing, budgeting, campaigns, catalog, chat, collections, configuration, content, contracts, corporateevents, customers, datasets, devices, documents, drivers, employees, expenses, featureflags, featurestore, fleet, forecasting, forms, fuel, fulfillment, giftcards, helpdesk, identity, invoicing, itsm, ledger, licensing, lineage, loyalty, maintenance, metrics, notifications, onboarding, orders, patients, payroll, pipelines, prescriptions, procurement, promotions, ratelimiting, recruiting, risk, routing, search, secrets, shipping, suppliers, surveys, telematics, timekeeping, travel, treasury, warehousing, webhooks, yards too.

Oracle

expected.json lists what scanning the repository must find: every handler, every call a handler or a program makes, and every field-level flow from where a handler has data to where a call or its response takes it, each tagged with the shape of the code that makes it. crates/graph/tests/fixture_coverage.rs in protomap-source checks a scan against it.

The code mixes in, on purpose, what makes static analysis of real code bases hard. Flows by pattern:
