HTTP Compression?

[digitalml]

Love this library, thanks!

Been using uWebSockets for webScokets but now I'm also trying to implement GET and POST. Obviously it's pretty easy except the compression part. I need to compress several semi large responses from a GET (500k) and compression: uWS.SHARED_COMPRESSOR, or any of the other compression enumerations do nothing to the GET response.

Does compression for an HTTP response require manual implementation? Can I somehow use a gZip lib without resorting to use express or fastify? I can't find anything in the documentation on this.

Any help is appreciated. Thank you.

You can use zlib, this is the way i used it:

const zlib = require('zlib');

and in your code you should check if the client accept encoding

const acceptEncoding = req.getHeader('accept-encoding');
let readStream = toArrayBuffer(fs.readFileSync(fileName));
 if (/\bgzip\b/.test(acceptEncoding)) {
     res.writeHeader('Content-Encoding', 'gzip');
     readStream = zlib.gzipSync(readStream);
    } else if (/\bdeflate\b/.test(acceptEncoding)) {
     res.writeHeader('Content-Encoding', 'deflate');
     readStream = zlib.deflateSync(readStream);
    }
    // else just original uncompressed 
    res.end(readStream);

@Wyzix33 thank you! This worked perfectly.
