Feature request: support custom hostname / non-localhost origin for the static server

[ltamazouzt]

Hi, and thanks for maintaining this library!

We are using react-native-static-server to serve a bundled a web page inside a React Native WebView. The webpage makes HTTP requests to our cloud API to load big files and metadata.

Currently the server is started with hostname: 'localhost', which means the WebView origin is http://localhost:8080. Because our cloud API is on a different domain, these requests are cross-origin, and the API must include http://localhost:8080 (or a wildcard) in its Access-Control-Allow-Origin response header which is a problem for us.

Would it be possible to support a custom hostname or a non-localhost origin?

Hmm... have you tried to pass in the desired host name into the hostname parameter of server constructor? Documentation for Lighttpd's bind option (where the hostname is passed to) mentions that it is legit to set it equal to www.example.org, so looking at that makes me think it might be working out of the box already. Otherwise, I don't know out of my head, what else should be modified to support it.

Hello, thanks for the quick reply.

I tested passing a custom domain (for example [www.example.org]) in the hostname parameter, but im getting an error as soon as i start the server

     const fileDir = resolveAssetsPath('somewhere');
 
        server = new Server({ fileDir, hostname: 'www.example.org', port: 8080, stopInBackground: true });
...
        console.log('before'); // i see that
        const res = await server?.start(); // crash 
        console.log('after'); // i dont see that
        if (res && server) {
          setOrigin(res);
        }

Would you help me to understand why you think this is something that can be fixed in the lighttpd config?

Instead of your web page having the client connect to localhost, have you tried using something like localhost.example.org and update your DNS to have localhost.example.org point to 127.0.0.1?
