Serializers

File: serializers.interface.ts

Introduction

The Serializers interface is a part of the error-enhanced library and is designed to handle serialization of the enhanced error objects. Serialization is a crucial aspect, especially when you need to log these errors or send them across network calls. The interface provides multiple serialization formats including JSON, XML, CSV, and YAML.

Methods

MethodReturn TypeDescription

toJSON(replacer?: (key: string, value: any) => any)

string

Serializes the error object to a JSON string. Accepts an optional replacer function.

toXML()

string

Serializes the error object to an XML string.

toCSV(delimiter?: string, quotes?: boolean)

string

Serializes the error object to a CSV string. Accepts optional delimiter and quote character flags.

toYAML()

string

Serializes the error object to a YAML string.

Example Usage

const error = new ErrorEnhanced([
  new SerializersUtility()
]);

// Serialize to JSON
const jsonString = error.toJSON();
console.log(jsonString);

// Serialize to XML
const xmlString = error.toXML();
console.log(xmlString);

// Serialize to CSV
const csvString = error.toCSV();
console.log(csvString);

// Serialize to YAML
const yamlString = error.toYAML();
console.log(yamlString);

Best Practices

  • Choose the appropriate serialization format based on the context in which the serialized error will be used. For example, use JSON for API responses and XML for SOAP-based web services.

  • For custom serialization, you can extend the provided methods or introduce new serialization formats.

Conclusion

The Serializers interface offers a robust and extensible way to serialize enhanced error objects into various formats. Understanding how to use these serialization methods effectively can be vital for error logging and transmission.
