Change default root url

[sepiropht]

I have an next/js app behind nginx with custom server node/express .
I launch it to port 3000. Nginx redirect the request myserver.com/mynextapp/ to port 3000 , but this is not working.
I can see the page server rendered, but the js doesn't working . In browser tool network i got 404 response for app.js and page/, because the request is myserver.com/_next/228ef92e59d376f055fc2c6d01c93b82/app.js instead of myserver.com/mynextapp/_next/228ef92e59d376f055fc2c6d01c93b82/app.js
It worked well when i simply opened the port 3000 in myserver.com but i try to avoid that.
Any idea ?
Thanks

This is a duplicate of #257. Please see that issue for some community solutions 👍

I ran into this issue as well and none of the solutions in #257 seem to resolve this.

I ended up modifying the server/index.js file and updating the routes in the method defineRoutes:
Object.keys(routes).map(route => { routes[this.renderOpts.assetPrefix + route] = routes[route]; });

I know this isn't the best solution right now but it's the only thing that works. Hopefully support for something like this is available in the future so I don't have to straight up modify core code.

@qwang06 how did you modify predefined next server routes?
It is something i need too. By i don't want to modify original file.
