fixes: #1177

Notable changes

  • Switched proxy from http-proxy to httpxy
    This replaces a long-standing core dependency and brings in many upstream fixes and behavior improvements documented by the httpxy project: Triage from upstream issues and PRs unjs/httpxy#2.

  • ESM-only package
    http-proxy-middleware now ships as native ES modules only. CommonJS require() usage is no longer supported, so imports should use ESM syntax.

  • Updated Node.js support policy
    Dropped Node.js 14, 16, 18, and 20.
    New minimum supported runtime is Node.js 22.15.0

  • Removed legacyCreateProxyMiddleware()
    The legacy compatibility wrapper has been removed as part of API cleanup. Use createProxyMiddleware() directly.

  • Added IPv6 literal support
    target and forward now support literal IPv6 URLs, for example: http://[::1]:3000.

  • Experimental Hono support
    Added createHonoProxyMiddleware() for Hono apps, including dedicated subpath support via http-proxy-middleware/hono.

Many thanks to everyone who helped make this release possible. 🙏
