Type Definitions

The type definitions of the values that you can get from getConnInfo() are the following:

type AddressType = 'IPv6' | 'IPv4' | undefined

type NetAddrInfo = {
  /**
   * Transport protocol type
   */
  transport?: 'tcp' | 'udp'
  /**
   * Transport port number
   */
  port?: number

  address?: string
  addressType?: AddressType
} & (
  | {
      /**
       * Host name such as IP Addr
       */
      address: string

      /**
       * Host name type
       */
      addressType: AddressType
    }
  | {}
)

/**
 * HTTP Connection information
 */
interface ConnInfo {
  /**
   * Remote information
   */
  remote: NetAddrInfo
}
