@gmode/client

@gmode/client

Lightweight typed fetch runtime for generated OpenAPI clients.

gmode generate client emits a self-contained gmode-client.ts that imports nothing at runtime except the platform fetch. This package provides the shared patterns and error types used by the generator.

Generated usage

gmode generate client --url http://localhost:8787/openapi.json --out ./generated

import { createClient } from "./generated/gmode-client";

const api = createClient({ baseUrl: "https://api.example.com" });
const user = await api.getUser({ params: { id: "u_1" } });

Errors

Failed responses throw ApiClientError with status, code, and parsed body:

try {
  await api.getUser({ params: { id: "missing" } });
} catch (err) {
  if (err instanceof ApiClientError) {
    console.log(err.status, err.body);
  }
}

See packages/cli/src/codegen/openapi-client.ts for the generator.
