deno-srv

World’s first Deno web server for multiple hosts.

• Uses Deno’s new, yet currently unofficial, sni callback!
• Comes with automatic tls certificate request! (while auto-renew isn’t there, yet - but will be included in the next release!)

Configure your web server in a language we all know and love: TypeScript.

Example on how to host your own, automatically https secured static website with automatic http-to-https redirect:

import * as Srv from "https://deno.land/x/srv@v0.3.0/srv.ts"

new Srv.HttpsListener(
  {
    autoRedirectHttps: true,
    hostHandlers:
    [
      new Srv.HostHandler("example.com",
        {
          handlers:
          [
            new Srv.FileHandler("/var/www/"),
          ]
        }
      ),
    ]
  }
);

Update: Deno v1.45.3 and up do not contain the DoS bug from rustls-tokio-stream anymore!

For people interested in Deno’s new sni callback

How to run the sni callback test

• Use Deno with version >= v1.43.3
• deno run -A ./config.ts
• Finally visit https://localhost:8008/test.txt
  • Note: You will receive a warning about an insecure certificate (because the certificate for ‘localhost’ is obviously self-signed)
• Now visit https://127.0.0.1:8008/test.txt, which will give you an error as ’127.0.0.1’ non-sni connections are currently not handled properly and there is no certificate for the host ‘127.0.0.1’
