Usage

Initialize:

import {SkipRuleEngine, EventDrivenRuleEngine,FormStateRuleEngine,OnDemandRuleEngineExecution, EventBinding,SetInputData} from 'kantime-rule-engine';

 ComponentDidMount() {
    SkipRuleEngine();
    EventDrivenRuleEngine();
    FormStateRuleEngine();
    EventBinding();
    }

    render() {
    let EngineInputdata={};
     EngineInputdata= {...};  
 SetInputData(EngineInputdata,this.props.masterRules,this.props.formRules);
 // It is used to verify the data and check return values for defined rule
        
    }

Examples of user defined business rules

On Demand Validation

"Rule1" : {
        "Eval" : [ 
            "EQ", 
            "doc.student.name", 
            ""
        ],
        "actionData" : {
            "print" : {
                "message" : "Name can't be blank",
                "tgtEleInfo" : [ 
                    "Student.Name", 
                    "Name", 
                    "Name"
                ]
            }
        }
    }

Event Driven

             "Rule1" : {
                "Eval" : [ 
                    "NOTBETWEEN", 
                    "doc.student.age", 
                    "0,14"
                ],
                "actionData" : {
                    "Mandate" : {
                        "message" : [ 
                            "Age must be between 0 to 14 ", 
                            "warning"
                        ],
                        "event" : "focusout",
                        "srcEleInfo" : [ 
                            "Student.Age", 
                            "stu_age"
                        ]
                    }
                }
            },

Skip Logic

     "Rule1" : {
                "Eval" : [ 
                    "EQ", 
                    "doc.student.physicalDisorder", 
                    "No"
                ],
                "actionData" : {
                    "Skip" : {
                        "srcEleInfo" : [

                            "stu_disorder"
                        ],
                        "tgtEleInfo" : [ 
                            "Student.Identification", 
                            "stu_ident"
                        ],
                        "skipEleInfo" : [ 
                            "stu_disorderType", 
                            "stu_certificateNo"
