helidon features and specs

  • Lightweight
    Helidon is designed to be a lightweight framework, which makes it an excellent choice for microservices and applications where performance and resource utilization are critical.
  • Microservices Focus
    Helidon is crafted with microservices architecture in mind, offering features and support that align well with cloud-native development strategies.
  • Helidon SE and MP Options
    Helidon provides both Helidon SE (simple, functional style development) and Helidon MP (MicroProfile standard), giving developers the flexibility to choose the programming model that best fits their needs.
  • GraalVM Support
    Helidon has support for GraalVM native image, which can significantly reduce startup time and memory usage, benefiting deployment and execution in cloud environments.
  • Reactive Programming
    With Helidon SE, developers can easily create reactive applications using a non-blocking, asynchronous programming model.

Possible disadvantages of helidon

  • Limited Ecosystem
    Compared to more established frameworks like Spring or Quarkus, Helidon's ecosystem of extensions, plugins, and third-party integrations is less extensive.
  • Smaller Community
    Helidon's community is not as large as some other Java microservices frameworks, which may mean fewer resources or community-driven support options are available.
  • Lack of Built-In Features
    While being lightweight is a benefit, it also means that Helidon might lack more comprehensive, built-in features that are found in larger frameworks, potentially requiring additional effort to implement common capabilities.
  • Newer in the Market
    Being a relatively newer framework, Helidon might not have as proven a track record or the same level of maturity and stability as older frameworks.

RxJava features and specs

  • Asynchronous Programming
    RxJava provides tools for composing asynchronous and event-based programs using observable sequences, making it easier to manage concurrent tasks.
  • Composability
    With RxJava, complex asynchronous workflows can be composed of simpler observable sequences, allowing for modular and reusable code.
  • Error Handling
    RxJava offers a wide range of operators and try-catch constructs to manage and respond to errors in a resilient manner.
  • Rich Operator Set
    RxJava comes with an extensive set of operators that can be used to filter, transform, and combine observable sequences for powerful data manipulation.
  • Backpressure Support
    The library provides the ability to handle backpressure, which helps manage situations where producers of data are faster than consumers.

Possible disadvantages of RxJava

  • Steep Learning Curve
    RxJava introduces a reactive programming paradigm that can be difficult for developers new to this approach to grasp immediately.
  • Complexity in Debugging
    The abstract nature of observables and operators can make it challenging to debug ReactiveX code compared to traditional imperative code.
  • Verbose Syntax
    Using RxJava often leads to more verbose code with chains of operators, which can decrease code readability if not well-documented.
  • Performance Overhead
    RxJava can introduce some performance overhead due to abstraction layers, which might not be suitable for all performance-critical applications.
  • Library Size
    For mobile applications, the size of the RxJava library can be a drawback if minimizing application size is a priority.

  • Year After Switching from Java to Go: Our Experiences
    But Javas has so many of these web frameworks?! * Spring (https://spring.io/) * Spring Boot (https://spring.io/projects/spring-boot) * Helidon (https://helidon.io/) * Micronaut (https://micronaut.io/) * Quarkus (https://quarkus.io/) * JHipster (https://www.jhipster.tech/) * Vaadin (https://vaadin.com/) That's just to mention the bigger ones, there's lots of mini frameworks like Javalin (https://javalin.io/) and... - Source: Hacker News / 3 months ago
  • Java web framework wihout annotations ?
    Maybe take a look at Helidon SE from Oracl (you find a short tutorial at https://www.baeldung.com/microservices-oracle-helidon). Source: almost 2 years ago
  • Javalin v5 has been released! (web micro-framework)
    If you’ve used NodeJS & ExpessJS, in Java world, Vert.x, Helidon and Javalin should be familiar. Source: over 2 years ago
  • Is it worth to learn Spring Boot ?
    If you’ve used ExpressJS, you could try Vert.x and Helidon. Source: almost 3 years ago
  • Average Oracle move
    You would think that if the site of one of the biggest programming languages is an abomination for both consumers and developers, then the one for a rest framework that the same company develops on the side should be even worse, but that's not the case as we are talking about oracle. How is the helidon website absolutely stunning on both mobile and desktop? It's still developed by oracle, just how is it possible... Source: almost 3 years ago
