@panda-tesla/bereshit-metadata-structure-validator

This package exposes single function called validateMetadataStructure which accepts a metadata object as input and returns true or false if metadata object is in correct form

Installation

Install Node, and then:

npm i @panda-tesla/bereshit-metadata-structure-validator --save

Usage

Validate metadata example:

Import & validate:

import { validateMetadataStructure } from '@panda-tesla/bereshit-metadata-structure-validator'

const isValid = validateMetadataStructure(metadata);

console.log(isValid);

Will print:

//for valid metadata 
{valid: true, errors: null}

//for invalid metadata
{valid: false, errors: [errors array]}

MetaData examples:

//valid metadata 
const metadata = [{
    entity: 'Cat',
    attributes: [ 
        {'name': 'smelly cat'},
        {'age': 8}
    ]
}];

valid metadata explanation:

metadata should be an array with two items. first item 'entity' with value string or number. second item 'attributes' with multiple object items, key value pair of string or number.

//inValid metadata
const metadata = {
     entity: {id: 123},
     attributes: {
         'name': 'smelly cat',
         'age': 8
     }
};

build your own schema!

validateMetadataStructure can receive an relative schema and vlidate occording to it.

const relativeSchema = {
 'type': 'object',
 'properties': {
     'entity': { 'type': 'number' },
     'attributes': { 'type': 'object' }
 }
};

const isValid = validateMetadataStructure(metadata, relativeSchema);
console.log(isValid);
