| ## Downloading Files | ||
| Puppeteer takes care of the file downloading. The decryption is being done as fast as possible (outruns native methods). Supports big files! | ||
|
|
||
| ```javascript | ||
| const hydraBot = require('hydra-bot'); | ||
| const fs = require('fs'); | ||
| const mime = require('mime-types'); | ||
|
|
||
| (async () => { | ||
| let client; | ||
| // start bot service | ||
| const ev = await hydraBot.initServer(); | ||
| // return connection information | ||
| ev.on('connection', async (conn) => { | ||
| // Was connected to whatsapp chat | ||
| if (conn.connect) { | ||
| client = conn.client; | ||
| } | ||
| }); | ||
| ev.on('newMessage', async (newMsg) => { | ||
| // when is received | ||
| if (!newMsg.result.isSentByMe) { | ||
| // message received! | ||
| console.log('NewMessageReceived: ', newMsg.result); | ||
| // dowload files | ||
| if (newMsg.result.isMedia === true || newMsg.result.isMMS === true) { | ||
| const buffer = await client.decryptFile(newMsg.result); | ||
| // At this point you can do whatever you want with the buffer | ||
| // Most likely you want to write it into a file | ||
| const fileName = `some-file-name.${mime.extension(newMsg.result.mimetype)}`; | ||
| fs.writeFile(fileName, buffer, (err) => { | ||
| console.log(err); | ||
| }); | ||
| } | ||
| } | ||
| }); | ||
| })(); | ||
