Take the lobby id from a pasted Poki or CrazyGames invite link by evanpelle · Pull Request #6105 · openfrontio/OpenFrontIO

evanpelle · 2026-10-23T23:57:28Z

Summary

Pasting a portal invite link into Join Lobby didn't work: extractLobbyIdFromUrl only looked for /game/<id> in the path.

Poki: invite links carry the id as a query param (poki.com/en/g/openfront?gdgameId=AbCd1234), so nothing was extracted.
CrazyGames: invite links look like crazygames.com/game/openfront?gameId=AbCd1234, and the path match returned openfront, which passes GAME_ID_REGEX (8–10 alphanumerics), so we tried to join a lobby called "openfront".

The modal now reads gdgameId, then gameId, from the query before falling back to the path. Our own /game/<id> links and bare ids are unchanged.

Test plan

JoinLobbyModal.test.ts: Poki preview + public links, CrazyGames link, our own link and a bare id. The Poki and CrazyGames cases fail without the fix.
npx vitest tests/client/JoinLobbyModal.test.ts (31 passed), oxfmt --check.

🤖 Generated with Claude Code

Join Lobby only looked for /game/<id> in a pasted URL. Poki's invite links carry the id as ?gdgameId=…, so pasting one did nothing, and CrazyGames' (/game/openfront?gameId=…) yielded "openfront", which passes GAME_ID_REGEX. Read gdgameId/gameId from the query before the path. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

Lobby ID extraction now checks the gdgameId and gameId query parameters before examining the URL path. Tests cover these portal links, OpenFront lobby links, and bare lobby IDs.

Lobby ID parsing

Layer / File(s)	Summary
Query parameter extraction and validation `src/client/JoinLobbyModal.ts`, `tests/client/JoinLobbyModal.test.ts`	`extractLobbyIdFromUrl` checks `gdgameId` and `gameId` values against `GAME_ID_REGEX` before path extraction. Tests cover Poki and CrazyGames links, OpenFront lobby links, and bare IDs.

An OpenFront link containing conflicting valid IDs can open the wrong lobby. This narrow case should be fixed or explicitly accepted before merging.

🤖 Claude Code Review

Verdict: Looks good. 0 findings (0 high, 0 medium, 0 low).

No issues found. Checked for bugs and CLAUDE.md compliance.

extractLobbyIdFromUrl now checks the gdgameId and then gameId query params, validated against the non-global GAME_ID_REGEX, before it falls back to the /game/<id> path. That fixes the CrazyGames case, where /game/openfront was wrongly read as a lobby id, and our own links and bare ids work as before. The new tests in tests/client/JoinLobbyModal.test.ts cover the Poki, CrazyGames, own-link and bare-id cases.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the ID in OpenFront lobby links.

If a pasted link is https://openfront.io/game/AbCd1234?gameId=EfGh5678, this line returns EfGh5678 instead of the path ID. The join flow can then open the wrong lobby. Prefer the path ID for OpenFront links, and use portal query parameters for portal links. Add a test with conflicting IDs.

The PR objective says existing /game/<id> links remain unchanged.
