@flarelog/sdk / wrapClient

Function: wrapClient()

wrapClient<T>(client): T

Defined in: ai/index.ts:153

Re-route an AI SDK client's internal fetch through globalThis.fetch.

Both the OpenAI SDK (openai v4+) and the Anthropic SDK (@anthropic-ai/sdk) capture globalThis.fetch at construction time and cache it on client.fetch for the instance's lifetime. If the client was constructed before @flarelog/sdk/ai was imported, it holds a reference to the raw native fetch and bypasses all instrumentation.

This function patches client.fetch to delegate to globalThis.fetch (which is flarelog's inert wrapper). Call it after flarelogAI():

Type Parameters

T

T extends object

Parameters

client

T

Example

import OpenAI from "openai";
import Anthropic from "@anthropic-ai/sdk";
import { flarelogAI, wrapClient } from "@flarelog/sdk/ai";

// Clients constructed early (e.g. at module scope in lib/ai.ts):
const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
const anthropic = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY });

// Activate instrumentation:
flarelogAI(logger);
wrapClient(openai);      // re-routes client.fetch → globalThis.fetch
wrapClient(anthropic);   // same — works for any client with .fetch

Not needed if the client is constructed after import "@flarelog/sdk/ai".
