@d-dash/datasource-grpc

gRPC-backed DatasourceAdapter for d-dash.

Usage

import { createGrpcDatasourceAdapter } from "@d-dash/datasource-grpc";

const adapter = createGrpcDatasourceAdapter({
  id: "grpc",
  client: {
    async query(request, context) {
      // Map request to protobuf call, then map response envelope.
      return { status: "success", frames: [] };
    },
  },
});

registry.registerDatasource(adapter);

Client contract

Your injected client handles transport specifics and returns a normalized envelope:

• query(request, context) is required
• getMetrics() is optional and enables metadata discovery

The adapter normalizes frame payloads to d-dash DataFrame[] and maps gRPC transport and response failures into structured datasource errors.
