如何对邮件附件 discord.js 做出反应

Question

So what I am trying to do is, my discord bot listens for attachments then takes them and sends them to a particular channel, I want it to also react it with and now I saw some solutions but they require message id and channel id, my channel id would remain the same but my message id would change every time I send an attachment how do I make it so it reacts to the attachment into that channel

My code:-

client.on("message", async message => {
  message.attachments.forEach((attachment) => {
    if (attachment.width && attachment.height) {
      if (message.author.bot) return
      let yes = attachment
      const channel = client.channels.cache.find(channel => channel.name === "llllllounge")
      channel.send(yes)
        .then(() => attachment.react('👍'))
        .then(() => attachment.react('👎'))
    }
  });
})

I have tried yes.react('') but it does not work and replies with yes.react is not a function
Would be grateful if someone helps me with this.

Answer 1

Channel#send returns a promise. Meaning we can use an asynchronous function in order to define the channel sending method using await (Send the message before defining it), and have our bot react to the newly sent message.

Final Code

client.on("message", message => {
  message.attachments.forEach(async (attachment) => {
    if (attachment.width && attachment.height) {
      if (message.author.bot) return
      let yes = attachment
      const channel = client.channels.cache.find(channel => channel.name === "llllllounge")
      const msg = await channel.send(yes)
        await msg.react('👍')
        msg.react('👎')
    }
  });
})
