  IMAGE               = 3,
  VIDEO               = 43,
  EMOTICON            = 47,
  LOCATION            = 48,
  APP                 = 49,
  MICROVIDEO          = 62,
}

When the return value of type is MsgType.APP, the return value of typeApp matches one of the following types:

AppMsgType {
  TEXT                     = 1,
  IMG                      = 2,
  VIDEO                    = 4,

  EMOJI                    = 8,
}

It should be noted that when forwarding ATTACH type message, if the file size is greater than 25Mb, the forwarding will fail. The reason is that the server shields the web wx to download more than 25Mb files with a file size of 0.

But if the file is uploaded by you using wechaty, you can forward it. You need to detect the following conditions in the message event, which can be forwarded if it is met.

.on('message', async m => {
  if (m.self() && m.rawObj && m.rawObj.Signature) {
    // Filter the contacts you have forwarded
    const msg = <MediaMessage> m
