Function: perServiceEnvResolver()

perServiceEnvResolver(map, options?): RemoteResolver

Defined in: packages/core/src/remoteResolver.ts:147

A resolver backed by per-service environment variables: map pairs each typeName with the name of the env var holding its base URL. A service with no mapping, or whose env var is unset/empty, resolves to null (→ Code.Unavailable). Replaces hand-rolled env registries in boot code.

Example

import { createCatalogClient, perServiceEnvResolver } from "@connectum/core";
import { serviceCatalog } from "./gen/catalog.gen.ts";

// Generate the catalog from the Greeter proto and set GREETER_URL
// to its server's HTTP/2 base URL before running this example.
const client = createCatalogClient({
  catalog: serviceCatalog,
  resolver: perServiceEnvResolver({
    "greeter.v1.GreeterService": "GREETER_URL",
  }),
});
const greeting = await client.call("greeter.v1.GreeterService/SayHello", { name: "Alice" });
console.log(greeting.message); // "Hello, Alice!"
