Overview

Error handling is an essential aspect of any software development process. Properly handling errors ensures that your application gracefully handles unexpected situations and provides meaningful feedback to users.

Types of Errors

Our Authentication Library may encounter various types of errors during operation. These errors can include:

• Invalid credentials
• Network errors
• Server errors
• Authentication failures
• Authorization errors

Error Codes

Each type of error may have specific error codes associated with it. These error codes can be helpful for identifying and debugging issues in your application.

Here are some example error codes:

• INVALID_CREDENTIALS: Indicates that the provided credentials are invalid.
• NETWORK_ERROR: Indicates a network-related error occurred.
• SERVER_ERROR: Indicates an error occurred on the server-side.
• AUTHENTICATION_FAILED: Indicates that authentication failed for the user.
• AUTHORIZATION_ERROR: Indicates that the user is not authorized to access the requested resource.

Handling Errors

When using our Authentication Library, it’s important to implement robust error handling mechanisms in your code. Here’s a basic example of how to handle errors:

try {
  // Attempt to perform authentication
  await auth.login(username, password);
  // If successful, proceed with accessing secure resources
} catch (error) {
  // Handle the error
  if (error.code === 'INVALID_CREDENTIALS') {
    // Display error message for invalid credentials
  } else if (error.code === 'NETWORK_ERROR') {
    // Display error message for network-related errors
  } else {
    // Display a generic error message
  }
}
