NestJS

CodeModuleInterceptor

Import the CheckUpstream dynamic module to initialize outbound fetch monitoring. This integration does not attach controller or handler context to requests.

SDK access required

Node.js and browser packages are not on public npm yet. Contact us for access before following the installation steps. Check the SDK reference for your runtime and review what the SDK sends.

1. Install

Bash

npm install @checkupstream/sdk

2. Import the dynamic module

src/app.module.ts

import { Module } from "@nestjs/common";
import { registerCheckUpstream } from "@checkupstream/sdk/integrations/nestjs";

const sdkKey = process.env.CHECKUPSTREAM_SDK_KEY;
if (!sdkKey) throw new Error("Set CHECKUPSTREAM_SDK_KEY before starting the app");

@Module({
  imports: [registerCheckUpstream({ sdkKey })],
})
export class AppModule {}

3. Flush during shutdown

Await checkupstream.shutdown() in your application's shutdown lifecycle before exiting. The module initializes the SDK; it does not register a Nest shutdown provider.
