Finite State Machines Backed by PostgreSQL Intro
If you’re new to the concept of Finite State Machines (FSMs), check out my previous blog post: Why Finite State Machines Are Everywhere: From Software to Human Life. That post explores how FSMs are fundamental to both software systems and real-world processes. Finite State Machine: In Various Languages FSMs as a concept have been implemented in many programming languages, each with its own data structures and libraries. For example: TypeScript/JavaScript: xstate is a popular library for modeling FSMs and statecharts. Python: Libraries like transitions provide easy-to-use FSM implementations. Java: Frameworks such as Spring State Machine offer robust FSM support. C#: Libraries like Stateless are widely used for FSMs. Go: Libraries like looplab/fsm provide simple and effective FSM implementations for Go. These libraries use different data structures—objects, classes, state tables, or even domain-specific languages—to represent states and transitions, but the core principles remain the same. ...
