Generic API

Every TRIAS 1.2 service request name can be invoked with a plain object body that mirrors the XML structure you want under that request element. Subscription requests use the same idea with subscribe.

Service requests

const rawResponse = await client.request("StopEventRequest", {
  Location: {
    LocationRef: {
      StopPointRef: "de:08212:90",
      LocationName: {
        Text: "Karlsruhe Hauptbahnhof",
        Language: "de",
      },
    },
    DepArrTime: "2026-03-20T21:10:00+01:00",
  },
});

console.log(rawResponse.parsed);

Return type: RawTriasResponse with status, parsed (typed as unknown unless you pass a generic), and xml (response body string).

Subscription requests

await client.subscribe("TripMonitoringSubscriptionRequest", {
  /* subscription body */
});

Generic request object

requestGeneric accepts { requestName, body } and delegates to request:

await client.requestGeneric({
  requestName: "FacilityRequest",
  body: { /* ... */ },
});

Building XML only

• buildGenericServiceRequest(requestName, body, requestTimestamp?): ServiceRequest envelope
• buildGenericSubscriptionRequest(requestName, body, requestTimestamp?): SubscriptionRequest envelope

Exported constants

Import these from trias-js to drive UI, validation, or exhaustiveness checks:

• TRIAS_SERVICE_REQUESTS: all supported service request names (includes LocationInformationRequest, TripRequest, StopEventRequest, etc.)
• TRIAS_SUBSCRIPTION_REQUESTS: subscription request names
• TRIAS_VERSIONS: currently ["1.2"]

TypeScript types TriasServiceRequestName and TriasSubscriptionRequestName match those arrays.
