@octokit/request-error

What is @octokit/request-error?

The @octokit/request-error npm package is designed to handle errors that occur during requests made using the Octokit library, which is a GitHub API client. It provides a structured way to catch and process errors, making it easier to debug and handle exceptions in applications that interact with GitHub's API.

What are @octokit/request-error's main functionalities?

Creating a RequestError instance

This feature allows developers to create an instance of RequestError, providing a message, status code, and request details. This can be useful for simulating errors in tests or handling errors in a structured way.

const { RequestError } = require('@octokit/request-error');

const error = new RequestError('Message describing the error', 404, {
  request: {
    method: 'GET',
    url: 'https://api.github.com/repos/octocat/Hello-World',
    headers: {
      authorization: 'token secret123'
    }
  }
});

Accessing error details

Once a RequestError instance is created, developers can access various details about the error, such as the HTTP status code, error message, and the request that caused the error. This is particularly useful for logging and debugging purposes.

const error = new RequestError('Not Found', 404, {
  request: {
    method: 'GET',
    url: 'https://api.github.com/repos/octocat/Hello-World',
    headers: {
      authorization: 'token secret123'
    }
  }
});

console.log(error.status); // 404
console.log(error.message); // Not Found
console.log(error.request.method); // GET

However, it is specifically tailored for Axios and its error handling patterns.
