## Summary The WebGL renderer was adapted from an external extension and carried a lot of machinery this integration never uses (replay playback, its own input/event system, a GL radial menu). This PR is two mechanical cleanup passes with **no behavior change**: delete the dead code, then untangle the `GameView` naming collision. **78 files, +142 / −2,197.** ### Pass 1 — remove dead extension baggage - **Replay/copy mode**: `FrameData.tileMode` was hard-coded `"live"`; the copy branches in `frame/Upload.ts`, `UploadOptions` (never passed), `applyFullFrame`/`applyFullTiles`/`applyDelta` on the facade and `GPURenderer`, `HeatManager.resetForSeek`, and the seek-upload methods on `TerritoryPass`/`TrailPass` were all unreachable. Also deletes `types/Replay.ts`, `types/FrameSource.ts`, `types/GameUpdates.ts`, `types/Game.ts` (imported only by the types barrel). - **FrameEvents**: trimmed from 14 fields to the 3 actually populated and read (`deadUnits`, `conquestEvents`, `bonusEvents`). The other 11 fed the extension's stats system and were never written or read here. - **GL radial menu**: `RadialMenuPass`, its 4 shaders, and ~10 API methods on facade + renderer had zero callers — the game uses the DOM/d3 radial menu in `hud/layers/RadialMenu.ts`. The pass was constructed and drawn every frame for nothing. - **Facade event system**: `GameViewEventMap` defined 10 event types (`click`, `hover`, `scroll`, …) but only `contextrestored` was ever emitted — input actually flows through `InputHandler` → EventBus → controllers. Replaced the listener map with a single `onContextRestored` callback and deleted `Events.ts`. Also fixed the stale header comment claiming the facade handles user interaction. - **Unused API surface**: removed ~20 facade/renderer methods with zero callers (camera passthroughs like `panTo`/`zoomTo`/`fitMap`/`screenToWorld`, hit-testing queries, SAM replay setters, `setSelectedUnit`, `clearFx`/`setFxTimeFn`, `onFrame`/`afterRender`/fps tracking). Deliberately left alone: `Camera`'s pan/zoom primitives (building blocks for a possible future camera unification) and the `timeFn` plumbing inside the FX passes (deeply embedded as defaults; only the dead renderer-level wrappers were removed). ### Pass 2 — untangle the three GameViews - `render/gl/GameView.ts` → **`MapRenderer.ts`** (class `MapRenderer`). Every importer was already aliasing it as `WebGLGameView` to dodge the collision with the simulation-mirror `GameView` in `client/view/`, so this removes aliasing rather than adding churn. `render/CLAUDE.md` updated. - Deleted the `src/core/game/GameView.ts` back-compat shim (its own TODO asked for this). All 51 importers now import from `src/client/view/` directly via a new 3-line barrel `view/index.ts`. ## Test plan - `tsc --noEmit` clean, `eslint` clean - Full test suite passes (1,385 + 65 server tests) - Manual verification via headless Chromium: started a singleplayer game and confirmed the renderer works end-to-end — terrain draws, spawn-phase overlay shows, territories fill with borders after spawning, player names/flags render, no renderer console errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Fable 5 <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
