djsv v3.0.5

jsonschema-validate-default

just a tiny libary based on jsonschema libary that allows you to test if your object is valid and if so to combine it with your deafults data

usage example

lazy

const validate = require('djsv');

// create your schema
const json = {
    "type": "object",
    "properties": {
        "id": {
            "type": "string",
            "default": "id",
            "required": true
        },
        "age": {
            "default": 30,
            "type": "integer"
        }
    }
}

 let validObject = validate(json,{id:"maty"}) // validObject.instance => {id:"maty",age:30}
 let validObject = validate(json,{id:"maty",age:20}) // validObject.instance => {id:"maty",age:20}
 let validObject = validate(json,{age:20}) //=> {id:"maty",age:20} => error:{valid:false, errorDescription:"id is required"}
 let validObject = validate(json,{id:123456}) //=> error:{valid:false, errorDescription:"id is not a string error "}

with schema initiation before

let validateWithSchema = validate(json);
let obj= { id: "12345", info: { age: 6 } };
console.log(JSON.stringify(validateWithSchema(obj).instance));

ignore null option

ignorenull option allows you to set the default param in the return object although the value is defiend

validateWithSchema = validate(json);
console.log(JSON.stringify(validateWithSchema({ id: "12345", info: { age: 6, familyName: null } }).instance)) //=> {"id":"12345","info":{"age":6,"familyName":null}}
console.log(JSON.stringify(validateWithSchema({ id: "12345", info: { age: 6, familyName: null } }, { ignoreNull:true }).instance)) //=>{"id":"12345","info":{"age":6,"familyName":"unknown"}}
