What it is
Anvil is an agent-native, multi-genre TypeScript game engine for browser, headless verification, and desktop shells. Games live beside the engine and consume public Anvil APIs. The repository includes an engine surface (anvil/) and a sample ARPG game (games/gravewake/).
How it works
The project provides an engine that is extended by genre-specific pieces (e.g., ARPG). Public APIs are consumed by games. There are documentation references for building or inspecting the engine surface and for authoring integration.
Getting started
Development setup requirements:
- Requires Node.js 22 or newer and pnpm 9.15.9.
Initial steps:
- cd anvil
- pnpm install
- pnpm -r run build
- pnpm test
- pnpm lint
- pnpm validate:examples
- pnpm test:examples
If running tests for M1–M9, use:
pnpm --filter @anvil/authoring --filter @anvil/genre-arpg test
Note: The complete pnpm check gate is described as not green due to failing CLI integration tests for unfinished schema-v2 scaffolding and commands. See the referenced document for details.
