Top 23 Java Reactive Projects

  • Vert.x

    Vert.x is a tool-kit for building reactive applications on the JVM

    • Project mention: Spark – A web micro framework for Java and Kotlin | news.ycombinator.com | 2024-02-10

    https://vertx.io/

    It's actively maintained with full time developers, performant, supports Kotlin out of the box, and has more features?

  • Quarkus

    Quarkus: Supersonic Subatomic Java.

    • Project mention: How Netflix Uses Java | news.ycombinator.com | 2024-02-27

    Meanwhile, if you're building something smaller than Netflix, I'm writing a book just for that (https://opinionatedlaunch.com/).

    It's about mobile apps, but I talk about backend at great length, especially since my background is Java. The book is called "opinionated" because I cover Quarkus (https://quarkus.io/), monolith, Fly.io, and no K8s.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • lettuce

    Advanced Java Redis client for thread-safe sync, async, and reactive usage. Supports Cluster, Sentinel, Pipelining, and codecs.

    • Project mention: Redis Cluster with heavy write application results in bad redis read latency | /r/redis | 2023-06-05

    I am using lettuce java library with async api. They says it used pipelining as default. Also I tried manually command flushing. I don't see the improvement.

  • reactor-core

    Non-Blocking Reactive Foundation for the JVM

    • Project mention: Is it wrong to use "try-catch" inside a reactive stream operator (project reactor)? | /r/learnprogramming | 2023-12-10

    I was exploring reactive streams with project reactor and I encountered a use case where I needed to skip to the next event if an error occurred during the processing of the current event (e.g. deserialization issue).

  • vertx-examples

    Vert.x examples
