Classify Client Errors

This feature allows you to classify whether an error is a client error (4xx status codes). The code sample demonstrates how to use the `isClientError` function to check if an error is a client error.

const { isClientError } = require('@smithy/service-error-classification');

const error = { statusCode: 400 };
if (isClientError(error)) {
  console.log('This is a client error.');
}

Classify Server Errors

This feature allows you to classify whether an error is a server error (5xx status codes). The code sample demonstrates how to use the `isServerError` function to check if an error is a server error.

const { isServerError } = require('@smithy/service-error-classification');

const error = { statusCode: 500 };
if (isServerError(error)) {
  console.log('This is a server error.');
}

Classify Throttling Errors

This feature allows you to classify whether an error is a throttling error (typically 429 status code). The code sample demonstrates how to use the `isThrottlingError` function to check if an error is a throttling error.

const { isThrottlingError } = require('@smithy/service-error-classification');

const error = { statusCode: 429 };
if (isThrottlingError(error)) {
  console.log('This is a throttling error.');
}
