Koa.js 启用 gzip 压缩

Question

const serve = require('koa-static');
const Koa = require('koa');
const compress = require('koa-compress');
const compressible = require('compressible');
const zlib = require('zlib');
const app = new Koa();

app.use(compress({
    filter: function (content_type) {
        return compressible(content_type);
    },
    threshold: 2048,
    flush: zlib.Z_SYNC_FLUSH
}));
// or use absolute paths
app.use(serve(__dirname + '/public'));

app.listen(3000);

console.log('listening on port 3000');
