HwTransportErrorType

Type of a Transport error used to represent all equivalent errors coming from all possible implementation of Transport

HwTransportError

Extends Error

Represents an error coming from the usage of any Transport implementation.

Needed to map a specific implementation error into an error that can be managed by any code unaware of the specific Transport implementation that was used.

Parameters

• type HwTransportErrorType
• message string

TransportError

Extends Error

TransportError is used for any generic transport errors. e.g. Error thrown when data received by exchanges are incorrect or if exchanged failed to communicate with the device for various reason.

Parameters

• message string
• id string

TransportStatusError

Extends Error

Error thrown when a device returned a non success status. the error.statusCode is one of the StatusCodes exported by this library.

Parameters

• statusCode number The error status code coming from a Transport implementation

• options {canBeMappedToChildError: boolean?} containing:* canBeMappedToChildError: enable the mapping of TransportStatusError to an error extending/inheriting from it . Ex: LockedDeviceError. Default to true. (optional, default {})

  • options.canBeMappedToChildError (optional, default true)

Similar packages

http-errors

http-errors is a package for creating HTTP errors for use with Express, Koa, Connect, etc. It provides a simple way to create error objects with HTTP status codes and messages. Unlike @ledgerhq/errors, which is tailored for Ledger hardware wallet applications, http-errors is more general-purpose and focused on web applications.

custom-error-generator

custom-error-generator is a package that allows you to create custom error classes with ease. It is similar to @ledgerhq/errors in that it provides a way to define custom error types, but it does not include predefined status codes or specific integrations for hardware wallets.

create-error

create-error is a utility for creating custom error classes. It is lightweight and flexible, allowing you to define custom properties and methods for your error classes. While it offers similar functionality to @ledgerhq/errors in terms of custom error creation, it lacks the specific focus on Ledger hardware wallet error handling.
