feat(dev): detect port conflicts on wildcard hosts by Kamaiko · Pull Request #21381 · vitejs/vite

Kamaiko · 2026-01-09T04:06:30Z

What is this PR solving?

When another dev server listens on 0.0.0.0:3000, Vite doesn't detect the conflict and binds to localhost:3000. Both servers bind to the same port, causing unexpected behavior.

This happens because Node.js treats 0.0.0.0 and localhost as different addresses, so no EADDRINUSE error is thrown.

Solution: Before starting the HTTP server, check if the port is already in use on wildcard addresses (0.0.0.0, ::). If blocked, Vite logs "Port X is in use, trying another one..." and automatically tries the next available port.

Fixes #10638
close #21419

What other alternatives have you explored?

Using get-port or detect-port packages: These solve the problem but add an external dependency. Vite prefers minimal dependencies, so a native net.createServer() approach was chosen instead.
Checking all possible hosts: Could check 127.0.0.1, ::1, etc., but unnecessary since the existing EADDRINUSE handler already catches those cases.

Happy to adjust based on feedback.

I guess this implementation won't work in case like:

localhost:5173 is listened
0.0.0.0:5174 is listened

Ensures isPortAvailable() runs for each new port after EADDRINUSE, preventing shadow conflicts with servers on 0.0.0.0 or ::.

Good catch! Refactored to an iterative loop that runs the wildcard check for each new port, including after EADDRINUSE. Your scenario (localhost:5173 + 0.0.0.0:5174 occupied) now correctly lands on port 5175.

Thanks!
