Microservices architecture has become the main architecture pattern to write servers in the last period. Node.js is one of the most popular technologies for writing servers in our days, rising in popularity. The best thing when starting from scratch is to go microservices, but even if you have a monolithic application you can do your newest parts in the microservice way. In this talk, I will talk about how to build microservices in Node.js. Which framework to use ( Express? Nest.js?) on each use case, which communication way to use according to the use case, and how to scale the microservices. After this talk, you will have the tools to build a better microservice environment.
