GraphQL subscriptions with Lacinia, and how it compares to Java and Node.js

Submitted Oct 28, 2019

I will share my experience using GraphQL subscriptions in various languages. I will both demo it’s use in an application, and share some performance test results comparing them.


I will explain a bit about GraphQL, and how GraphQL subscriptions can be used to steam events from the backend to the frontend. After explaining how I implemented Lacinia, I will share my experience doing the same with Java and Node.js, and share some results from performance tests, comparing the different implementations.
