Fixes #3213.

🧭 Context

On npmjs.com, visiting /org/<name> redirects to /~<name> when <name> belongs to a user account instead of an org. npmx didn't do this — both /org/<name> and /~<name> worked as separate valid pages for the same person, which doesn't match npm's behavior.

📚 Description

The tricky part here is that you can't detect "is this a user" by checking whether the org-packages endpoint 404s — I checked with curl and /-/org/<name>/package returns 200 for both real orgs and user accounts, so that signal doesn't distinguish them at all.

Instead I used /-/org/<name>/user, which does distinguish cleanly:

  • {} → real org
  • {"<name>": "owner"} → user account
  • 404 → doesn't exist as either

The redirect now lives in canonical-redirects.global.ts, alongside the other legacy-URL redirects (like the existing /@org/org/org one), since that's the right place to do this before the page even starts rendering. I added a timeout on the registry call so a slow/hanging lookup can't block the request — if the check fails or times out for any reason, it just falls through to the normal org page/404 behavior instead of blocking anything.

Added tests for:

  • redirect firing for a user account
  • no redirect for a real org
  • no redirect for a name that doesn't exist at all
  • the check failing gracefully (falls through, doesn't error)
  • an E2E test confirming the actual browser redirect works end to end

One tradeoff worth flagging for reviewers: /-/org/<name>/user isn't in npm's public API docs as an unauthenticated endpoint (it's documented as requiring a session token), but it works fine without auth in practice — I tested it directly with curl. If npm ever locks that down, this redirect would just stop firing and things would go back to today's behavior, not break anything.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added automatic redirects from /org/<name> to the corresponding /~<name> user profile when the name belongs to a user account.
    • Query parameters are preserved, and redirects use a permanent (301) status.
  • Bug Fixes

    • Organisation pages continue to render normally when the name belongs to a real organisation or cannot be verified.
    • Registry checks now fail promptly if the service is unavailable.
  • Tests

    • Added coverage for user redirects, organisation handling, errors, timeouts, and query-string preservation.

Walkthrough

The change adds npm registry org-user fixtures, detects user accounts for exact /org/<name> routes, redirects them to /~<name>, preserves query strings, and leaves organisation routes and registry errors unchanged.

Changes

Org URL canonicalisation

Layer / File(s) Summary
Registry org-user fixture lookups
modules/runtime/server/cache.ts, test/fixtures/mock-routes.cjs, test/fixtures/npm-registry/org-users/*
Fixture handling now supports /-/org/<name>/user responses. Empty fixtures represent organisations, populated fixtures represent user accounts, and missing fixtures return 404 responses. Fixture paths remain inside the fixture directory.
Canonical org-to-user redirect
server/middleware/canonical-redirects.global.ts, test/unit/server/middleware/canonical-redirects.spec.ts
Exact /org/<name> paths query the registry. Non-empty responses redirect with status 301 to lowercase /~<name> paths and preserve query strings. Empty responses and fetch errors fall through. Requests use a 5-second timeout with retries disabled.
End-to-end URL validation
test/e2e/url-compatibility.spec.ts
The URL compatibility test verifies that /org/qwerzl resolves to /~qwerzl.
