How to send binary data #1020

Closed nikitaulshin closed 7 years ago

nikitaulshin commented 7 years ago

Hello!

I'm building an app using awesome Koa2. Could you please tell me how can I send binary data (i. e. ArrayBuffer)?

Thanks!

Buffer Data

const buf = Buffer.alloc(1024);
ctx.body = buf;

Stream object

const stream = fs.createReadStream(__filename);
ctx.body = stream;
