Feature Request: Enable relative path like http://www.example.com/hackmd

[adachij2002]

I'd like to configure apache to serve hackmd at any route like http://example.com/hackmd.

I haven't tried this yet, I use nginx more.
But I think you can achieve that by reverse proxy?

[adachij2002]

Yes, I'm using mod_proxy_http as follows, that works fine.

<Location />
    ProxyPass http://localhost:3000/
    ProxyPassReverse http://localhost:3000/
</Location>

But It's not working as follows, because static file or redirect path uses fixed path like "/", "/new", "/css" and so on.

<Location /hackmd>
    ProxyPass http://localhost:3000/hackmd
    ProxyPassReverse http://localhost:3000/hackmd
</Location>

[jackycute]

OK, I will see what I can do.

You will need following configs for apache (I tried):

For example, your url is www.example.com/hackmd, hackmd run on port 3000

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^socket.io [NC]
RewriteCond %{QUERY_STRING} transport=websocket [NC]
RewriteRule /hackmd/{.*} ws://localhost:3000/$1 [P,L]

RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteRule /hackmd/(.*) ws://localhost:3000/$1 [P,L]

ProxyRequests Off
ProxyPreserveHost On

ProxyPass        /hackmd http://localhost:3000
ProxyPassReverse /hackmd http://localhost:3000

ProxyPass        /hackmd/socket.io http://localhost:3000/socket.io
ProxyPassReverse /hackmd/socket.io http://localhost:3000/socket.io

ProxyPass        /hackmd/socket.io ws://localhost:3000/socket.io
ProxyPassReverse /hackmd/socket.io ws://localhost:3000/socket.io

Hi @adachij2002
Did you see this issue update?
Please tell me when you're good.

[adachij2002]

It works fine for me.Thank you!
But this apache configuration is a little bit complex.
Is it difficult to wait on the following URL by Node.js?

http://localhost:3000/hackmd
http://localhost:3000/hackmd/socket.io
ws://localhost:3000/hackmd/socket.io

[jackycute]

It's not possible without proxy http://localhost:3000/hackmd
But seems ok to be like this:

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^socket.io [NC]
RewriteCond %{QUERY_STRING} transport=websocket [NC]
RewriteRule /hackmd/{.*} ws://localhost:3000/$1 [P,L]

RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteRule /hackmd/(.*) ws://localhost:3000/$1 [P,L]

ProxyRequests Off
ProxyPreserveHost On

ProxyPass        /hackmd http://localhost:3000
ProxyPassReverse /hackmd http://localhost:3000

[adachij2002]

It's not possible without proxy http://localhost:3000/hackmd

I see.

Do you Sing in via OAuth with that configuration?
I caught error as follows.

Not Found
The requested URL /auth/github/callback was not found on this server.

I configured apache like this

ProxyPass        /auth http://localhost:3000/auth
ProxyPassReverse /auth http://localhost:3000/auth

But I caught error as follows.

AuthorizationError: The redirect_uri MUST match the registered callback URL for this application.

[jackycute]

Actually, you don't need to config apache like that (proxy /auth)

That error is caused by the OAuth provider setting's callback url not match the one you send.
So you need to modify the callback url whenever you change your server url.

For example, GitHub would like this:

Sorry for my miss configuration.
It works fine!
Please close this ticket.
Thanks a lot.

👍 Happy Coding!
