Uploading image from discord.js bot to my website

Question

I want to use message.attachments to get images from that and upload those to my website (not on localhost). How would i do that?

I already have a working upload form on my website, but how would i do it from a discord.js bot?

Answer 1

According to the discord.js docs , each attachment has a URL property. You can use this to get the image and upload it.

Example code:

const URLsToFetch = [];
const attachments = message.attachments.array();
for(let i = 0;i<attachments.length;++i){
  URLsToFetch.push(attachments[i].url);
}

This would get all the attachment URLs, which you can use http , request , or some other similar module to download it and then write it to wherever you put your uploads:

const http = require("http");
const https = require("https");
const {URL} = require("url");
const fs = require("fs");
for(let url of URLsToFetch){
  const uri = new URL(url);
  const protocol = uri.protocol;
  let proto = http;
  if(protocol === "https:"){
    proto = https;
  }
  proto.get(uri,response=>{
    const chunks = [];
    response.on("data",chunk={
      chunks.push(chunk);
    });
    response.on("end",()=>{
      const file = Buffer.concat(chunks);
      fs.writeFile("path/to/filename",file,err=>{
        if(err){throw err} // error
        // successfully wrote file
      });
    });
  });
}
