**Add approved & assigned issue number here:** N/A — maintainer follow-up to #4227. ## Description: Follow-up to #4227, finishing the "info.json is the single source of truth" refactor. **Maps.gen.ts now generates one `MapInfo` interface and a `maps` list** instead of parallel lookup records. `mapCategories`, `mapTranslationKeys`, and `multiplayerFrequency` are gone — consumers read the list directly (`map.categories`, `map.translationKey`, `map.multiplayerFrequency`). MapPicker got simpler in the process: it renders from `MapInfo` objects, so the reverse `Object.entries(GameMapType)` lookup to recover the enum key is gone. The featured-rank sort moved out of the Go codegen into the picker, where the presentation concern belongs. **`SPECIAL_TEAM_MAPS` moves into info.json** as an optional `special_team_count` field (set on the same 17 maps with the same values). MapPlaylist derives its map from the generated list; `SPECIAL_TEAM_FORCE_CHANCE` and the frequency multiplier behavior are unchanged. **The en.json `map` section is now generated.** A new optional `display_name` field in info.json (defaulting to `name`) is written to `resources/lang/en.json` by the generator, preserving the section's non-map UI keys (`map`, `featured`, `all`, `favorites`, `random`). The 8 maps whose English display name intentionally differs from the frozen enum value (e.g. `MENA`, `Milky Way`, `Europe (Classic)`, `Baikal (Nuke Wars)`) declare it via `display_name`, so no display text changes. The section is emitted alphabetically; since #4232 already sorted en.json and every value matches, regeneration is byte-identical and this PR has no en.json diff. Other languages remain Crowdin-managed. The generator also now validates `translation_key` is exactly `map.<folder>` and `special_team_count >= 2`. MapConsistency tests compare info.json directly against the generated list and the en.json section, and fail with a "run `npm run gen-maps`" message on drift. No behavior changes: enum values, playlist frequencies, special-team counts, featured order, and display names are all byte-identical. ## Please complete the following: - [x] I have added screenshots for all UI updates (no UI changes — internal refactor, rendering output identical) - [x] I process any text displayed to the user through translateText() and I've added it to the en.json file - [x] I have added relevant tests to the test directory ## Please put your Discord username so you can be contacted if a bug or regression is found: evanpelle 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>

🚀 Installation
-
Clone the repository
git clone https://github.com/openfrontio/OpenFrontIO.git cd OpenFrontIO -
Install dependencies
npm run instDo NOT use
npm installnornpm ibut instead use ournpm run inst. It runs the safernpm ci --ignore-scriptsto install dependencies exactly according to the versions inpackage-lock.jsonand doesn't run scripts. This can prevent being hit by a supply chain attack.
🎮 Running the Game
Development Mode
Run both the client and server in development mode with live reloading:
npm run dev
This will:
- Start the webpack dev server for the client
- Launch the game server with development settings
- Open the game in your default browser (to disable this behavior, set
SKIP_BROWSER_OPEN=truein your environment)
Client Only
To run just the client with hot reloading:
npm run start:client
Server Only
To run just the server with development settings:
npm run start:server-dev
Connecting to staging or production backends
Sometimes it's useful to connect to production servers when replaying a game, testing user profiles, purchases, or login flow.
To replay a production game, make sure you're on the same commit that the game you want to replay was executed on, you can find the
gitCommitvalue viahttps://api.openfront.io/game/[gameId]. Unfinished games cannot be replayed on localhost.
To connect to staging api servers:
npm run dev:staging
To connect to production api servers:
npm run dev:prod
