I see this "I'd never use node" sentiment quite a bit in the Java community. I'm always curious for the reason. Is it the JavaScript? or is Node unable to perform? After reading so many success stories from Netflix and Walmart, I'm wondering what the missing piece is....
Specifically in the area of high CPU load tasks. NodeJS is perfectly fine for heavily async tasks, especially calling out to external services. When you have CPU intensive tasks the lack of control over the event loop (task list) can be painful.
It’s not just Java, it’s any programmer with proficiency in any other language, including those that are quite proficient at JavaScript. The sentiment after our team wrapped up a recent Node project for a client was basically “the internet keeps lying about the maturity of the node ecosystem”. That was with the latest TypeScript and an architect who was very good.
The event loop model that Node uses is easily replicated in other programming languages. It’s not a sensible default though, blocking code is better for most domains.
