const multer = require('multer')
const app = express()
const port = 4000
const storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './uploads')
},
filename: function (req, file, cb) {
const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1E9)

}
});
client.on('qr', (qr) => {
// Generate and scan this code with your phone
console.log('QR RECEIVED', qr);
});
client.on('ready', () => {
console.log('Client is ready!');
});
client.on('message', msg => {
if (msg.body == '!ping') {

client.initialize();
app.set('view engine', 'ejs');
app.use(expressLayouts);
app.use(express.urlencoded({

app.get('/', function (req, res) {
var locals = {

});
app.post('/kirim', upload.single('gambar'), (req, res) => {
let number = req.body.nowa + "@c.us";
let message = req.body.pesan;
let gambar = MessageMedia.fromFilePath(req.file.path)
client.sendMessage(number, gambar, {
caption: message
});
//console.log(number);
res.json()
})

console.log(`Example app listening on port ${port}`)
})
