stompjs VS nestjs

Websocket is also not a protocol. It's a way to send and receive bytes - a socket - but how you interpret those bytes is up to the underlying protocol. We use stomp which covers our needs well, and one of its features is including an custom headers to the 'CONNECT' message.

When you're going to use RabbitMQ I would advise to use the RabbitMQ library at https://github.com/golevelup/nestjs. It's way more flexible than the default RabbitMQ microservice.

For this, I'm going to be using a package called @golevelup/nestjs-modules to help with the creation of the dynamic module. Instead of having to set up the entire forRoot and forRootAsync methods, we can extend a mixin and let the package take care of the setup for us. everything in this article will work without the package, I just like using it for the sake of simplicity. So, lets dive into setting up our AuthModule to be a dynamic module. First we need to create our injection token for the options

import { Injectable, NestMiddleware } from '@nestjs/common' import { json } from 'body-parser' /** * Copied this middleware to parse the raw response into a param to use later * from https://github.com/golevelup/nestjs/blob/master/packages/webhooks/src/webhooks.middleware.ts */ @Injectable() export class RawBodyMiddleware implements NestMiddleware { public constructor() {} public use(req: Request, res: Response, next: () => any): any { json({ verify: (req: any, res, buffer) => { if (Buffer.isBuffer(buffer)) { const rawBody = Buffer.from(buffer) req['parsedRawBody'] = rawBody } return true }, })(req, res as any, next) } }

The easiest thing to do is just mock all of a services methods with jest mock functions. I like to do that with this library: https://github.com/golevelup/nestjs/tree/master/packages/testing
