JavaScript Business Rules Engine allows modeling Business Rules in Natural Language or as Decision Tables, deploying and executing anywhere where JavaScript is available such as mobile apps and web apps.

It will be easier to understand the benefits if we look at an example first.

Model Business Rules in Natural Language or as a Decision Table without JavaScript Knowledge

Using FlexRule® Advanced Decision Management Suite, the following example shows you how you can easily model business rules in Natural Language or as a Decision Table and deploy them in the JavaScript environment without writing the JavaScript code from scratch.

The sample scenario shows how to use Natural Language to validate the relations between school staff and students. It is a simple list of logic written in a human-readable manner.

You can model the same business rules as a Decision Table. This is even easier to understand and change.

As you can see that we have not written any JavaScript code.

Once you model the business rules in FlexRule Designer, you can debug, simulate, execute, and deploy. FlexRule automatically converts your Natural Language file or Decision Table into JavaScript.

Furthermore, the FlexRule JavaScript engine comes with a built-in JS testbed. You can test your logic in the Design phase before deploying.

You can select the logic for testing, making it easier to diagnose the issues and testing each logic thoroughly.

Now that you looked at an example let’s see the benefits in detail.

JavaScript Business Rules Engine: Model, Deploy, Execute and Change Effortlessly

If you are thinking about how JavaScript Business Rules Engine is useful,

  1. Understand and Model Business Rules efficiently
    Even the non-technical users without JavaScript knowledge can visually model the business rules as Decision Tables or Natural Language and deploy them in JavaScript. You can use monadic operators and expressions.
  2. Flexible Deployment/ Execution Options (In-Proc or Service Layer)
    You can either execute your business rules locally without calling a server, or you can use your business decisions as a service calling via a REST API endpoint. Depending on your requirements, you can choose to execute on the client-side, server-side, or both.
  3. Highly Maintainable
    Unlike writing the business logic in JavaScript, Decision Tables and Natural Language are easy to change and re-deploy, making it highly maintainable.
  4. Fast and Easy Testing
    The built-in JS testbed allows testing the logic faster, and you don’t even need to deploy it for testing logic. This helps to enhance the accuracy of your app.
