RxJava logo RxJava

RxJava – Reactive Extensions for the JVM is a library for composing asynchronous and event-based programs using observable sequences.

Apache FreeMarker logo Apache FreeMarker

Java template engine; generates HTML web pages, e-mails, configuration files, source code, etc. from template files and the data your application provides.

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.

  • Using FreeMarker template engine in Sitecore Personalize
    FreeMarker is a template engine, it allows to generate text output based on templates and dynamic data. It is similar to Mustache, Handlebars, Thymeleaf and other template engines. Templates are written in the FreeMarker Template Language (FTL) that supports conditional blocks, iterations, formatting, and many other capabilities. - Source: dev.to / over 1 year ago
  • m8a scenario #1 - Using Coder to Develop Keycloak Templates Live (almost)...
    Getting back to our two main technologies....we have implemented Keycloak as our Identification and Authorization Management system (IAM). However, as these things go, Keycloak has its own tech stack. One of the technologies, of course, is the language they used, which is Java. And being it is Java, they chose to use a templating engine called Freemarker. - Source: dev.to / about 2 years ago
  • Typescript, Webpack and legacy jquery with plugins
    The project I was working on was a website using Magnolia as their CMS. It uses the Freemarker templating engine under the hood. Essentially these are super-powered HTML files, which give you access to the CMS content. You can still use all of the HTML tags you want, including the. - Source: dev.to / over 2 years ago
  • Can I use Java to build a website?
    You can use Java for Backend and Frontend. A relative new kid on the block for Frontend is Qute. The general keyword you are searching for is Java Templating Engine. Specific examples would be Thymeleaf or FreeMarker. There are some framework, which offer a lot more than templating like Vaadin or Wicket. Some are just specifications like Jakarta Faces with some of their implementations MyFaces or Mojarra. Source: over 2 years ago
  • How to create a Keycloak plugin
    Keycloak uses FreeMaker to store and render templates. Read more about how Keycloak manages its themes in the official documentation. - Source: dev.to / over 2 years ago
