About this package

@frank/hermes-client

Typed server-side client for the two contracted Hermes surfaces (gateway API Server and rich hermes serve), plus event normalization, the append-only redacted event projection, and the Hermes redaction layer. Ported from apps/window/hermes_adapter/ and merged with the server.py inline client (W113, W114): behaviour, allowlists, timeouts, size caps, fail-closed gates and redaction rules are unchanged.

Public API

  • RestSurface, ENDPOINT_SPECS, resolvePath, encodeQuery, RestError
  • GatewayClient (runs, sessions, chat stream), ServeClient + serveStatusGate
  • AdDbClient, adDbQuery, adDbPublicPayload, mediaRequest, gatewayBaseUrl
  • normalize, derivedLabel, SequenceTracker (event envelope)
  • EventProjection (caps, receipts, compaction, TTL prune)
  • redactText, redactUrl, redactValue, REDACTED
  • configFromEnv() - the only process.env reader; everything else is parameters

Config

The caller passes URLs and runtime secret resolvers (apiKey: () => string). configFromEnv() reads HERMES_ENDPOINT/HERMES_API_URL, HERMES_API_KEY, HERMES_PROFILE, HERMES_SERVE_URL, HERMES_SERVE_TOKEN and FRANK_PRIVATE_BRIDGE_HOSTS. Base URLs must be loopback, bridge, or https.

Example

import { configFromEnv, GatewayClient } from "@frank/hermes-client";
const env = configFromEnv();
const gw = new GatewayClient({
  baseUrl: env.gatewayUrl,
  apiKey: () => env.gatewayKey,
  profile: env.profile,
  bridgeHosts: env.bridgeHosts,
});
const { body } = await gw.submitRun({ input: "hello", idempotency_key: "ops:..." });
for await (const frame of await gw.runEventsStream(String(body.run_id))) {
  // frame: { event, data, id }
}

Errors: every call throws RestError. chatStream throws on an upstream error instead of emitting SSE error/done frames like the Flask stream did; the route that relays it to the browser re-emits those frames.
