Introduction

The @nesn/commons-shared-objects-schema-validator module aims to streamline the validation of data against JSON schemas. By leveraging the Ajv library, it ensures that data structures conform to specified schemas, enabling reliable and consistent data processing. This module can be integrated with any codebase that requires schema-based validation.

Installation

To include the @nesn/commons-shared-objects-schema-validator module in your project, you can install it using npm:

npm install @nesn/commons-shared-objects-schema-validator

Usage

Importing

Import the validateObjectAgainstSchema function from the module:

import { validateObjectAgainstSchema } from '@nesn/commons-shared-objects-schema-validator';

Validation

The validateObjectAgainstSchema function takes two parameters: the data object to be validated and the JSON schema against which the data will be validated. If the data adheres to the schema, the function returns true. If not, it throws a SchemaValidationError.

Here's an example of using the validator with the NormalizedSubscription interface and schema:

import { validateObjectAgainstSchema } from '@nesn/commons-shared-objects-schema-validator';
import { NormalizedSubscription } from '@nesn/commons-shared-objects-normalized-subscription';

const subscriptionData = /* your subscription data */;
try {
    validateObjectAgainstSchema(subscriptionData, NormalizedSubscription);
    console.log('Data is valid!');
} catch (error) {
    if (error instanceof SchemaValidationError) {
        console.error('Validation error:', error.message);
        // Handle validation errors
    } else {
        // Handle other errors
    }
}

Customization

The @nesn/commons-shared-objects-schema-validator module provides a default SchemaValidationError class for handling validation errors. You can extend or modify this class to suit your project's needs. This might include additional error information or custom error messages.
