API

serializeError(value)

Type: Error | unknown

Serialize an Error object into a plain object.

Non-error values are passed through. Custom properties are preserved. Non-enumerable properties are kept non-enumerable (name, message, stack). Enumerable properties are kept enumerable (all properties besides the non-enumerable ones). Circular references are handled.

deserializeError(value)

Type: {[key: string]: unknown} | unknown

Deserialize a plain object or any value into an Error object.

Error objects are passed through. Non-error values are wrapped in a NonError error. Custom properties are preserved. Circular references are handled.
