Connectum API Reference / @connectum/cli / utils/reflection / fetchFileDescriptorSetBinary

Function: fetchFileDescriptorSetBinary()

fetchFileDescriptorSetBinary(url, options?): Promise<Uint8Array<ArrayBufferLike>>

Defined in: utils/reflection.ts:283

Fetch FileDescriptorSet as binary (.binpb) from a running server via reflection.

The binary output can be passed directly to buf generate as input. The same completeness and time-limit rules as fetchReflectionData apply.

Parameters

url

string

Server URL (e.g., "http://localhost:5000")

options?

ReflectionOptions = {}

Time limit of each request

Returns

Promise<Uint8Array<ArrayBufferLike>>

Binary FileDescriptorSet (.binpb format)

Example

import { mkdirSync, writeFileSync } from "node:fs";
import { fetchFileDescriptorSetBinary } from "@connectum/cli/utils/reflection";

const binpb = await fetchFileDescriptorSetBinary("http://localhost:5000");
mkdirSync(".tmp", { recursive: true });
writeFileSync(".tmp/descriptors.binpb", binpb);
// Then: buf generate .tmp/descriptors.binpb --output ./gen
