Business rules engine is a lightweight JavaScript library for easy business rules definition of the product, the contract, the form etc. This validation engine is UI agnostic and that is why it can be used as an independent representation of business rules of a product, contract, etc.

Rules are composed of simple json structures, making them human readable and easy to persist. This example demonstrates an engine for detecting whether a basketball player has fouled out a player who commits five personal fouls over the course of a minute game, or six in a minute game, fouls out.

This is available in the examples. This example demonstates an engine for identifying employees who work for Microsoft and are taking Christmas day off. This demonstrates an engine which uses asynchronous fact data. Fact information is loaded via API call during runtime, and the results are cached and recycled for all 3 conditions.

It also demonstates use of the condition path feature to reference properties of objects returned by facts. The examples above provide a simple demonstrations of what json-rules-engine can do. To learn more about the advanced features and techniques, see the docs and read through the examples. There is also a walkthrough available. Rules may be easily converted to JSON and persisted to a database, file system, or elsewhere. To convert a rule to JSON, simply call the rule. Later, a rule may be restored by feeding the json into the Rule constructor.

Why aren't "fact" methods persistable? This is by design, for several reasons. Firstly, facts are by definition business logic bespoke to your application, and therefore lie outside the scope of this library.

Secondly, many times this request indicates a design smell; try thinking of other ways to compose the rules and facts to accomplish the same objective. Finally, persisting fact methods would involve serializing javascript code, and restoring it later via eval. If you have a strong desire for this feature, the node-rules project supports this though be aware the capability is enabled via eval. Skip to content.

Node-rules is a light weight forward chaining rule engine written in JavaScript.

Avoid modifying the engine inside action blocks i. There are safer ways of doing this. I see the better way to assert fact upon matching action is to use gen.

But I don't see how to retract facts. The documentation states that the library leverages the predicate library and i would like to use. But I get an invalid predicate error when i use something like this An open-source IoT platform that enables rapid development, management and scaling of IoT projects.

This works in a very simple way by giving you an ability to put your rules in a store outside the core logic of the system thus ensuring that any change in rules doesn't affect the core system.

To install this library, please download the latest version of NuGet Package from nuget. The expressions are supposed to be a lambda expressions. You can inject the rules into the Rules Engine by initiating an instance by using the following code. Here, workflowRules is a list of deserialized object based out of the schema explained above and logger is a custom logger instance made out of an ILogger instance.

Once done, the Rules Engine needs to execute the rules for a given input. It can be done by calling the method ExecuteRule as shown below. Here, workflowName is the name of the workflow, which is Discount in the above mentioned example.

And input is the object which needs to be checked against the rules. The response will contain a list of RuleResultTree which gives information if a particular rule passed or failed. A demo app for the is available at this location. The rules can be stored in any store and be fed to the system in a structure which follows a proper schema of WorkFlow model.

The wrapper needs to be created over the Rules Engine package, which will get the rules and input message s from any store that your system dictates and put it into the Engine. Also, the wrapper then needs to handle the output using appropriate means. This project welcomes contributions and suggestions.

You can build a simple rules engine yourself. All you need is to create a bunch of objects with conditions and actions, store them in a collection, and run through them to evaluate the conditions and execute the actions. This is exactly what Easy Rules does, it provides the Rule abstraction to create rules with conditions and actions, and the RulesEngine API that runs through a set of rules to evaluate conditions and execute actions.

This is the hello world of Easy Rules. You can find other examples like the ShopAirco or WebApp tutorials in the wiki. If you found a bug or want to request a feature, please use the issue tracker.

Drools is a business rule management system with a forward-chaining and backward-chaining inference based rules engine, allowing fast and reliable evaluation of business rules and complex event processing.

A rule engine is also a fundamental building block to create an expert system which, in artificial intelligence, is a computer system that emulates the decision-making ability of a human expert. Be sure to check out the Drools' project website and documentation! If you want to build or contribute to a kiegroup project, read this document.
