It looks inspired by express.js, is it the case or are they both inspired by an older framework?

#12I just started using this! Spring Boot seemed so convoluted, having to go to a website to even begin. And then to have the Tomcat dependency seemed like a heavy lift just to get a "hello world" working. Virtual threads seems to be the way to go.

#13I haven’t tried this framework, but just looking at some examples, the web sockets and sse seem a bit out of place. In a Loom world you’d expect these to use channels or queues or something similar in a loop - not callbacks. Callback hell is what virtual threads try to avoid. I’m not sure if loom has any primitives like go’s multi-channel select that might make this workable though.
In either case Loom and frameworks that use it are super exciting! I’m looking forward to removing the 20 different thread pools we need to avoid deadlocks and just using the common one in our Clojure apps.

#14I find that hello world example very pleasant to look at. Love that it's effectively a one-liner.
public static void main(String[] args) {
var app = Javalin.create(/*config*/)
.get("/", ctx -> ctx.result("Hello World"))
.start(7070);

#15Congratulations! This is great!
Java deserves its comeback among the wave of nu-programming we are going through.

Both inspired by Sinatra, the OG :)

#17Can we use this to render traditional apps (no js frameworks)?

Express is inspired by Connect JS in terms of middleware — middleware written for Connect works in Express. The middleware style I believe is originally inspired by Rack, a Ruby project.
Sinatra, also Ruby, predates Express and is based on Rack (in a similar way to Express, which used to be based on Connect if I’m not mistaken).
I’m not sure what inspired Sinatra, but that’s probably the influence you’re seeing in these frameworks.

Absolutely!

#20Javalin is amazing.
Kudos.
