What is @ethersproject/logger?
@ethersproject/logger is a logging utility designed for use with the ethers.js library. It provides a simple and consistent way to log messages, warnings, and errors, making it easier to debug and track issues in your Ethereum-related applications.
What are @ethersproject/logger's main functionalities?
Logging Messages
This feature allows you to log informational messages. The logger instance is created with a context name ('my-app' in this case), which helps in identifying the source of the log messages.
const { Logger } = require('@ethersproject/logger');
const logger = new Logger('my-app');
logger.info('This is an info message');
Logging Warnings
This feature allows you to log warning messages. Warnings are useful for indicating potential issues that are not necessarily errors but should be looked into.
const { Logger } = require('@ethersproject/logger');
const logger = new Logger('my-app');
logger.warn('This is a warning message');
Logging Errors
This feature allows you to log error messages. Errors indicate serious issues that need immediate attention.
const { Logger } = require('@ethersproject/logger');
const logger = new Logger('my-app');
logger.error('This is an error message');
Custom Error Codes
This feature allows you to create and throw custom errors with specific error codes. This is useful for categorizing and handling different types of errors in a more granular way.
const { Logger } = require('@ethersproject/logger');
const logger = new Logger('my-app');
const error = logger.makeError('Custom error message', 'CUSTOM_ERROR_CODE');
logger.throwError('This is a custom error', 'CUSTOM_ERROR_CODE', { additional: 'info' });
