Jooby VS javalin

One of the good things about it is that using asynchrony is optional. If you don't have to call out anywhere to build the response, processing can all stay in the handler's calling thread. If you do, you can return a future and have the library handle the async for you.

One downside is that it is based on Jetty which isn't considered the most performant backend. A lib with a similar API but based on Netty is Jooby [1] which scores well in the Techempower benchmarks.

Jooby and Helidon SE are among the best.

The code snippet gave me a vibe like it was jooby Looks cool, I suggest maybe start incorporating Project Loom virtual threads in the future.

Speaking of backend development, recently I gave Jooby[1] a try after discovering it was one of the world's top performer in Tech Empower's web framework benchmark[2].

Surprisingly enough, it's terribly easy to put together a REST API with Jooby. I wonder why it's adoption rate is so low.

Do you need to use Spring btw? If you want to broaden the tool selection I've had great success with i.e Jooby (https://jooby.io/) together with Kotlin coroutines. Another alternative is the KTOR framework.

Jooby I think is the best bet. https://jooby.io/ watch out for jooby dot org I think someone sniped the domain.

Spring Boot or JAXRS. I personally use Jooby a lot which is similar in style to spark but has annotation support and isn't a singleton.

If you've read this far, you might be interested to know that Javalin has been offering Brotli compression through jvm-brotli for three years already, and that there have been no (reported) issues. In other words, the effort required to release and maintain this is probably not huge.

I'm a big fan of Ktor (ktor.io) but another reasonable lightweight alternative is Javelin (https://javalin.io/). Heck even Spring Boot isn't that bad. HikariCP + JooQ (has both java and kotlin codegen) for DB access if you need and you're good to go.

A similar alternative that does not rely on web sockets is https://htmx.org. I have greatly enjoyed using it with some simpler web frameworks like https://javalin.io to do some prototyping and smaller projects. I'm sure if someone made a plug and play UI library like material UI for Angular on top of htmx you could absolutely fly through MVPs.

Javalin

If you're already familiar with most of the concepts around HTTP and web services, I'd recommend using something like https://javalin.io/ which is light weight frame work that makes getting something up and running quickly a very easy task.

I've been looking at https://javalin.io/ Seems close enough to express and some big names are using it, so I wouldn't say it's fizzling out

Javalin (https://javalin.io) is strongly inspired by Express and Koa, so you should feel right at home:

If you want to do a proper comparison between the two, I would be happy to help with code examples from Javalin's side. I could even host it on https://javalin.io as a "Comparison to Jooby" blog post.
