Reactive Programming paradigm for Go for event-driven applications

Summary

ro - Reactive programming for Go A Go implementation of the ReactiveX spec. The purpose of Reactive Programming is to simplify the development of event-driven and asynchronous applications by providing a declarative and composable way to handle streams of data or events. 💖 Support This Project I’m going all-in on open-source for the coming months.

What makes it different from samber/lo? lo: synchronous helpers across finite sequences (maps, slices...) ro: processing of infinite data streams for event-driven scenarios The Reactive Programming paradigm Reactive Programming is focused on handling asynchronous data streams where values (like user input, API responses, or sensor data) are emitted over time. Instead of pulling data or waiting for events manually, you react to changes as they occur using Observable , Observer , and Operator . This approach simplifies building systems that are responsive, resilient, and scalable, especially in event-driven or real-time applications. observable := ro . Pipe ( ro . RangeWithInterval ( 0 , 10 , 1 * time . Second ), ro . Filter ( func ( x int ) bool { return x % 2 == 0 }), ro . Map ( func ( x int ) string { return fmt . Sprintf ( "even-%d" , x ) }), ) // Start consuming on subscription observable . Subscribe ( ro . OnNext ( func ( s string ) { fmt . Println ( s ) })) // Output: // "even-0" // "even-2" // "even-4" // "even-6" // "even-8" Now you discovered the paradigm, follow the documentation and turn reactive: 🚀 Getting started Core package Full documentation here. The ro library provides all basic operators: Creation operators : The data source, usually the first argument of ro.Pipe : The data source, usually the first argument...
