Can you explain the purpose of connectMicroservice and startAllMicroservicesAsync functions in nestjs?

While looking through the codebase, I came across connectMicroservice and startAllMicroservicesAsync in an application using Nest.

Could someone please clarify what these functions are used for?

I attempted to research them in the official Nest documentation, but couldn't find any information.

Answer №1

These techniques are geared towards a hybrid application, functioning with both a traditional HTTP server as well as a microservice server within the same server application

Answer №2

The function connectMicroservice is responsible for launching a microservice instance within the application in addition to the standard HTTP server.

By using the startAllMicroservices method, all previously connected microservices that were set up with connectMicroservice will be initialized. The startAllMicroservicesAsync method performs this initialization asynchronously compared to starting up the HTTP server.
