neuron-js: Pluggable Execution Runtime

neuron-js is a lightweight, extensible, and JSON-serializable execution engine for JavaScript. It allows developers to define complex logic flows (functional scripts) that can be stored in a database, transmitted over the wire, and executed consistently in both Node.js and browser environments.

The Problem

Hardcoding business logic often leads to rigid systems that are difficult to update without a full deployment. Workflow engines are often heavy, difficult to integrate, or use proprietary formats.

The Solution

neuron-js provides a registry-based approach to execution logic:

• Neuron (Registry): Stores the definitions of what is possible (Actions, Conditions, Rules, Parameters).
• Synapse (Engine): Executes specific scripts by coordinating these definitions in a logical flow.

By keeping the script format strictly serializable (JSON), neuron-js enables:

• Dynamic Logic: Change business rules at runtime without redeploying code.
• Portability: The same logic can run on a backend server or in a client's browser.
• Extensibility: Easily add new capabilities by implementing simple Action or Condition interfaces.

Key Features

• JSON Serializable: Logic is data.
• Shared Context: State is managed and passed through the execution chain.
• Logical Grouping: Complex AND/OR condition logic is supported out of the box.
• Lifecycle Hooks: Monitor and react to every step of the execution.
• Type Safe: Built with TypeScript for a robust developer experience.
