    Class BaseError

    Base class for custom errors with repaired subclass prototypes and names.

    Call imprint in subclass constructors on runtimes where extending native Error does not preserve the expected prototype chain.

    import { BaseError } from '@pacote/error'

    class StatusError extends BaseError {
      constructor(public readonly status: number, message?: string) {
        super(message)
        StatusError.imprint(this)
      }
    }

    const error = new StatusError(404, 'Not found')
    error instanceof StatusError // => true
    error.name // => 'StatusError'
