What is eth-rpc-errors?

The eth-rpc-errors package provides utilities for creating and managing Ethereum JSON-RPC errors. It helps standardize error handling in Ethereum-related applications by providing predefined error codes and messages.

What are eth-rpc-errors's main functionalities?

Creating Custom Errors

This feature allows you to create custom errors with specific codes, messages, and additional data. It is useful for defining application-specific error conditions.

const { ethErrors } = require('eth-rpc-errors');

const customError = ethErrors.rpc.custom({
  code: 1234,
  message: 'Custom error message',
  data: { additional: 'info' }
});

console.log(customError);

Predefined Errors

The package provides predefined errors for common JSON-RPC error conditions, such as invalid parameters, method not found, and internal errors. This helps standardize error responses across different applications.

const { ethErrors } = require('eth-rpc-errors');

const invalidParamsError = ethErrors.rpc.invalidParams('Invalid parameters provided');

console.log(invalidParamsError);

Error Serialization

This feature allows you to serialize JavaScript errors into a format that can be easily transmitted over JSON-RPC. It ensures that error information is consistently formatted.

const { serializeError } = require('eth-rpc-errors');

const error = new Error('Something went wrong');
const serializedError = serializeError(error);

console.log(serializedError);
