Backwards compatibility

http2 is supported as far back as the now obsolete internet explorer 11 so most people should not need to worry about Backwards compatibility. sicarii does however support Backwards compatibility, should you have any need for requiring it.

• config.server.allowHTTP1 will enable/disable Backwards compatibility.
• the server stream event is reserved for http2, but the server request event is not and will not ever be required by sicarii.
• the server stream event will always ignore all non http2 requests.
• the request event will enable you to accept http1 requests using the nodejs http compatibility layer.
• sicarii stream methods are not supported when using the http2 compatibility layer.
• the request event is limited to methods in the nodejs http compatibility api but can be manually extended to mimic most of the stream events.

const { app, cluster } = require('sicarii');

if(cluster.isMaster) {

  const { sync } = require('sicarii/master');

  sync.init().respawn().listen();

} else {

  const { server, router, crypt } = require('sicarii/main');

  server.on('request', function (req, res) {
    if(req.httpVersion !== '2.0'){ // version check is mandatory
      // do something
      console.log('i am a http1 connection!')

      res.writeHead(200, { 'Content-Type': 'application/json' });
      res.end(app.js({test: 'ok'});

    }
  })

  router.get('/', function(stream, headers, flags){

    console.log('i am a http2 connection!')
    stream.status(200).render('index.html', {
      title: 'http2 connection'
    })

  });



  server.pre_cache().push_handler(true).listen(app.config.port);
