Editor for Microsoft Rules Engine - Blazor UI library intended for integration in Web or Desktop
Rules Engine Editor is a library/NuGet package for use with Microsoft Rules Engine which itself is a package for abstracting business logic/rules/policies out of a system.
To install this library, download the latest version of NuGet Package from nuget.org.
There are several ways to populate workflows for the Rules Engine Editor as listed below.
Rules are based on the Microsoft Rules Engine schema definition and can be stored in anything deemed appropriate like Azure Blob Storage, Cosmos DB, Azure App Configuration, Entity Framework, SQL Servers, file systems etc. For RuleExpressionType LamdaExpression, the rule is written as a lambda expressions.
The Rules Engine Editor can also use a format for Input Rule Parameters based on the schema defintiion and can likewise be stored as the aforementioned workflow schema. Input Rule Parameters allow the seeding of arbitrary input data to be used in the Rules Engine. Consider Input Rule Parameters like interactive "unit tests" which allow for "What-If" type analysis.
