What it does

RuleGo is a lightweight framework for Go that enables high-performance component orchestration, allowing startup founders to efficiently manage and automate complex workflows and rules

When to use it
  • •When building a Go-based application that requires scalable and performant rule-based decision making
  • •When integrating multiple components or services that need to be orchestrated and managed dynamically
  • •When developing a real-time system that requires fast and efficient processing of rules and events
Ready-to-paste prompt
go run main.go -rule "example-rule" -event "example-event" -condition "condition=value" -action "action=take"
Heads up: Make sure to handle errors properly when working with RuleGo, as the `rulego.NewEngine` function returns an error value that needs to be checked and handled, e.g., `engine, err := rulego.NewEngine(); if err != nil { log.Fatal(err) }`
