Setup for NestJS on Lambda

Install Supergood as Middleware for your NestJS application.

Install the Supergood library

npm install supergood@latest

Initialize the Supergood library as middleware

Create new middleware as supergood.middleware.ts or add to existing middleware. Setting useRemoteConfig: true will introduce an additional async call on Lambda start, and will allow certain Supergood features to be available such as fine-grained redaction and on-premise schema validation.

This middleware flushes the Supergood cache after your response is returned to the client, so it will not slow down your lambda function.

import { Injectable, NestMiddleware } from '@nestjs/common';
import { Request, Response, NextFunction } from 'express';

export class SupergoodMiddleware implements NestMiddleware {
  async use(req: Request, res: Response, next: NextFunction) {
    const Supergood = require('supergood');
      clientId: process.env.SUPERGOOD_CLIENT_ID,
      clientSecret: process.env.SUPERGOOD_CLIENT_SECRET,
      config: {
        useRemoteConfig: false,

    res.on('finish', async () => {
      await Supergood.close();


Add the Supergood middleware

Inside of app.module.ts

Add the Supergood middleware to any route containing API calls you wish to track. This example applies Supergood middleware to all routes.

export class AppModule implements NestModule {
  configure(consumer: MiddlewareConsumer) {

Example Repository

Here is an example repository of Supergood running on a NestJS application deployed on Lambda.
