App.domain docs

[MarcJo]

This code works with v20.10.0 fails with v20.15.0 and v20.19.0
It's may be caused due to 'Improved SNI support' in uWebSockets v20.18.0 which does not look to be implemented.

const port = 443
SSLApp( {} )
.addServerName( 'page1.com', {
	key_file_name  : 'page1.com/key.pem',
	cert_file_name : 'page1.com/cert.pem',
} )
.addServerName( 'page2.com', {
	key_file_name  : 'page2.com/key.pem',
	cert_file_name : 'page2.com/cert.pem',
} )
.missingServerName( ( hostname ) => {

	console.log( 'Hello! We are missing server name <' + hostname + '>' )

} )
.get( '/*', ( res, req ) => {

	res.end( 'Hello World!' )

} )
.listen( port, ( token ) => {

	if ( token ) {

		console.log( 'Listening to port ' + port )

	} else {

		console.log( 'Failed to listen to port ' + port )

	}

} )

Please read the release post. You attach routes to SNI domains using app.domain(..). You haven't specified any default SSL cert and you haven't attached any route to your "SNIs"

[MarcJo]

Thanks. Please provide type definition for app.domain(..).

This is working solution (checked with v20.19.0)

const port = 443
SSLApp( {} )
.addServerName( 'page1.com', {
	key_file_name  : 'page1.com/key.pem',
	cert_file_name : 'page1.com/cert.pem',
})
.domain('page1.com')	
.get( '/*', ( res, req ) => {

	res.end( 'Hello World! 1' )

} )	
.addServerName( 'page2.com', {
	key_file_name  : 'page2.com/key.pem',
	cert_file_name : 'page2.com/cert.pem',
} )
.domain('page2.com')	
.get( '/*', ( res, req ) => {

	res.end( 'Hello World! 2' )

} )	
.missingServerName( ( hostname ) => {

	console.log( 'Hello! We are missing server name <' + hostname + '>' )

} )
.listen( port, ( token ) => {

	if ( token ) {

		console.log( 'Listening to port ' + port )

	} else {

		console.log( 'Failed to listen to port ' + port )

	}

} )

Hi, thanks for this! I was looking on how to implement SNI with uwebsockets and this is the only reference I could find, and it works!

[denyaalt]

How use one callback .any( '/*',( res, req )=>{}) for all SNI domains? (and dynamically add SNI domain)
I call .addServerName() inside missingServerName(), but all HTTP connections are blocked.

[jaime-ez]

this is more or less what I did, I have an array of domains: ["domainA", "domainB"] and the I do:

      const server = uWS.SSLApp(...opts)
      for (const domain of domains) {
        if (domain !== '') {
          server.addServerName(domain, {
           ...options
          })
        }
      }

And then

      server.listen(host, port, ( => {
        for (const domain of domains) {
          let app = server
          if (domain !== '') {
            app = server.domain(domain)
          }
          app.post("/*", (res, req) => { ....
``

Hope it helps
