127.0.0.1 instead of localhost not an allowed redirect url

[onionhammer]

Describe the bug

I'm trying to configure my OIDC provider to redirect back to vite running locally, and while localhost works fine, 127.0.0.1 is now advertised in the console as the link to click on.

Why was this changed? According to the history the title of the #8543 it looks like it should show the opposite. It should at least be configurable..

Reproduction

Create a new vite app, run npm run dev, in console it shows "local: http://127.0.0.1..."

Workaround: Run vite with --host argument

It's explained in the docs.

https://vitejs.dev/config/server-options.html#server-host

The first case is when localhost is used. Node.js under v17 reorders the result of DNS-resolved address by default. When accessing localhost, browsers use DNS to resolve the address and that address might differ from the address which Vite is listening. Vite prints the resolved address when it differs.
You can set dns.setDefaultResultOrder('verbatim') to disable the reordering behavior. Vite will then print the address as localhost.

I suggest upgrading your Node.js version or manually setting dns.setDefaultResultOrder('verbatim') in the Vite config.
Otherwise, the possibility remains that another server can also listen on localhost:5050 and hijack the connections from Vite.
