Send image URL using whatsapp-web.js

To send an image with a URL using whatsapp-web.js, you can use the Client.sendImage method with the url parameter. Here is an example code:

const fs = require('fs');
const path = require('path');
const axios = require('axios');
const qrcode = require('qrcode-terminal');
const { Client , MessageMedia } = require('whatsapp-web.js');

const client = new Client();
const folderPath = 'D:/xampp/htdocs/api-whatsapp/downloads';

function sendFileFromUrl(chatId, message, fileUrl) {
    const filename = path.basename(fileUrl);
    const filePath = path.join(folderPath, filename);

    axios({
      url: fileUrl,
      responseType: 'stream'
    }).then(response => {
      response.data.pipe(fs.createWriteStream(filePath));
      response.data.on('error', err => {
        console.error(err);
      });
      response.data.on('end', () => {
        console.log('File downloaded successfully!');
        const media = MessageMedia.fromFilePath(filePath);
        client.sendMessage(chatId, media, message).then(() => {
            console.log('sent successfully!');
            fs.unlinkSync(filePath);
        }).catch((err) => {
            console.error('Error sending: ', err);
            fs.unlinkSync(filePath);
        });
      });
    }).catch(err => {
      console.error(err);
    });  
}

client.on('qr', (qr) => {
    qrcode.generate(qr, {small: true});
});

client.on('ready', () => {
    console.log('Client is ready!');

    const chatId = '62123456789@c.us';
    const message = 'This is file';
    const fileUrl = 'https://pmb.uii.ac.id/wp-content/uploads/2020/04/Panduan-Merubah-Dokumen-ke-Format-PDF-Secara-Online.pdf';
    sendFileFromUrl(chatId, message, fileUrl);
});

client.initialize();
