RuleForge

A library for adding a rules engine to your web app

Create a rules engine for your app in minutes, that would take days to create from scratch.

Add complex rules to your web app quickly via simple commands to RuleForge's classes.

Features

• A ready-built structure for organising your rules
• An efficient engine for processing rules at scale
• A simple structure that can be picked up easily
• Create simple rulesets quickly via chaining with the RuleForge class
• Fire actions from passed rules immediately, or en masse when you want to

Installation

RuleForge can be installed via Node Package Manager (NPM).

npm install @ruleforge/ruleforge

Documentation

Documentation can be found on the RuleForge GitHub Pages site here

Getting Started

A getting started guide will be added here soon, but in the meantime check out the example.ts and example2.ts files for two ways to get started.

There are a few different building blocks that make up RuleForge's rule engine. These are the five you will use, and what they are for:

• Fact: An object you pass with your own properties to check your rules against.
• Condition: An individual check you make on the Fact.
• Rules: Contain the Conditions that must all be met for the Rule to pass.
• Actions: The function you want to run when the Rule passes.
• Ruleset: A container for your Rules.
• RuleForge: A class that allows your rulesets to be created via chaining (see example2.ts)

In short:

1. Create a ruleset.
2. Create a rule in the ruleset.
3. Create an action in the rule.
4. Add conditions to the rule.
5. Repeat 2-4 until you have all the rules you need.
6. Create a fact, with the data you'll be checking your rules against.
7. Run the fact through the ruleset.
