Koa JavaScript
Isang JavaScript snippet para sa Koa na sumasagot sa mga request sa /pixel.gif gamit ang empty GIF, na isang beses lang dine-decode sa startup.
Koa JavaScript
import Koa from 'koa';
import Router from '@koa/router';
const GIF = Buffer.from('R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==', 'base64');
const app = new Koa();
const router = new Router();
router.get('/pixel.gif', (ctx) => {
ctx.type = 'image/gif';
ctx.set('Cache-Control', 'no-store');
ctx.body = GIF;
});
app.use(router.routes()).listen(8080);
Pinatakbo namin ang snippet na ito at ikinumpara ang mga byte na ibinalik nito.
