## What Game creation no longer requires the caller to pick the `gameID` or compute its owning worker. The client POSTs to a prefix-less `/api/create_game`; **nginx (prod) and the vite dev proxy randomly route it to a worker**, which **mints an id that hashes back to itself** and returns it along with its `workerIndex`. ## Why it stays correct The minted id still hashes to the creating worker (via the existing `generateGameIdForWorker`), so everything downstream that derives the worker from the gameID — websocket connect, share URL, join flow — keeps working unchanged. The only thing that moved is *who picks the id and worker*. ## Changes - **`src/server/Worker.ts`** — factor create into a shared `createGameForId`; add `POST /api/create_game` (no id) that mints a self-owned id and returns `gameInfo` + `workerIndex`/`workerPath`. The existing `POST /api/create_game/:id` stays. - **`nginx.conf`** — `location = /api/create_game` proxies to a `random` worker upstream. - **`generate-nginx-upstream.sh` + `Dockerfile`** — the entrypoint generates that upstream from `NUM_WORKERS` at container **start** time. `NUM_WORKERS` isn't known at image build time (the image is built once and deployed with different env), so it can't be baked into `nginx.conf` — hence runtime generation of exactly the live worker ports (no dead-server padding). - **`vite.config.ts`** — dev-only middleware forwards `POST /api/create_game` to a random worker. Vite's `http-proxy` can't pick a per-request random target, so this is a small middleware plugin (same pattern as the existing `serveProprietaryDir`), registered before the `/api` proxy. - **`src/client/HostLobbyModal.ts`** — stop generating the id client-side; use the server's. ## Behavior change to note The host's share link used to be copied **instantly** from a client-generated id. Now the id comes from the server, so the copy waits one create round-trip — I moved the URL build/copy into the create `.then` (and kept the failure path that clears the clipboard). Brief empty-link state in the modal until create resolves. ## Verification - tsc + eslint clean; full suite green (1543 tests). - nginx additions validated with `nginx -t` in isolation (the full file references container-only paths like `/etc/nginx/mime.types`); upstream + `proxy_pass` resolve. - `generate-nginx-upstream.sh` tested with `NUM_WORKERS` set and unset (defaults to 1). Not yet exercised live end-to-end (needs a dev-server restart — `vite.config.ts` + `Worker.ts` changes aren't hot-reloaded). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
OpenFront.io is an online real-time strategy game focused on territorial control and alliance building. Players compete to expand their territory, build structures, and form strategic alliances in various maps based on real-world geography.

📋 Prerequisites
- npm (v10.9.2 or higher)
- A modern web browser (Chrome, Firefox, Edge, etc.)
🚀 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
