  • Spark – A web micro framework for Java and Kotlin
    I'd recommend Javalin (https://javalin.io/) instead. Same idea, only executed better and it is actively maintained. - Source: Hacker News / 2 months ago
  • Spark – A web micro framework for Java and Kotlin
    SparkJava has an actively developed fork/successor called Javalin[1]. It's straightforward to convert from SparkJava to Javalin. The latter is written in Kotlin, but works fine with ordinary Java. While the rest of the Java world was devolving into annotation hell, AOP and other nightmares, these Java microframeworks showcased what happens when you forego legacy Java and leverage modern Java language features... - Source: Hacker News / 2 months ago
  • Show HN: Zero-dependency Java framework out of beta
    The size statistics page is super cool: https://github.com/byronka/minum/blob/master/docs/size_comparisons.md Aside from that, I've also had good experiences with Dropwizard - which is way simpler than Spring Boot but at the same time uses a bunch of idiomatic packages (like Jetty, Jersey, Jackson, Logback and so on): https://www.dropwizard.io/en/stable/ I do wonder whether Minum would ever end up on the... - Source: Hacker News / 7 months ago

  • What is the point of uWSGI?
    I'm looking at the WSGI specification and I'm trying to figure out how servers like uWSGI fit into the picture. I understand the point of the WSGI spec is to separate web servers like nginx from web applications like something you'd write using Flask. What I don't understand is what uWSGI is for. Why can't nginx directly call my Flask application? Can't flask speak WSGI directly to it? Why does uWSGI need to get... Source: about 2 years ago
