How to change the HMR domain (the "origin")?

[Joe Pea]

I'm running my dev server online, and it detect the HMR domain to be my server's IP, like 34.234.56.4:3003, and it tries to access https://34.234.56.4:3003 at runtime, which is not allowed by my server.

How I can I specify for it to use a certain domain? F.e., I'd like it to use dev.example.com:3003 so that at runtime it will access https://dev.example.com:3003 without problems.

Right now, I see errors like this in Chrome devtools:

https://34.234.56.4:3003/socket.io/?EIO=3&transport=polling&t=MrMerUL&b64=1 net::ERR_CONNECTION_REFUSED

because the server doesn't not allow connections like that.

It's hard to come up with search terms to find the right search results.

Turns out these are my two exact issues, the second one due to the first:

1. #156
2. #107

I'll close this, as I think HMR_URL will do the trick.

Alright, I can use HMR_URL to specify the domain, but how do I tell it not to use a port? I need HMR to just access a URL with only domain, without the port.

[Joe Pea]

Dang, looks like there's no way, the code does:

const PORT = parseInt(process.env.HMR_PORT) || parseInt(process.env.VUE_DEV_SERVER_PORT) || getMeteorPort() || 3003

which forces the port to exist.

[Joe Pea]

For reference, that code prevents from doing this:

HMR_URL=dev-server.example.io HMR_PORT="" meteor -p 2345

because the empty string returns falsey in the code.

EDIT: Actually, the dev-server still needs the port, in order to launch the server.

[Joe Pea]

So, a port is still needed for dev-server, just that the client should not try to use a port.

It'd be great to have a way to tell only the client code not to use a port (but the server still need to read the HOST_PORT env var, and fallback to the meteor port +3, in order to launch).

There always is a port when you use the network on a computer. By default, using http the port is 80 and https it's 443. The list of commonly used ports on wikipedia.

You can't start a server without a port.
