The Leumas ecosystem

168 packages, engines, services and adapters. Check here before writing a helper: rebuilding something that already works is the most expensive mistake in this repository, and the new code never looks wrong.

@leumas/exportersThe ONE way anything in Leumas leaves the app — serialize a value to JSON/NDJSON/CSV/text, hand it to the browser as a download, and wrap it in a versioned envelope so a file exported from one Leumas...42 exportsused by 3
@leumas/featuresShared user-facing surfaces — providers, guards, the app shell, and the Dashboard/Social/AppIndex/Account/Imperium pages that Web, Studio and iOS all compose. Studio adds admin pages on top.231 exportsused by 4composes 16
@leumas/game-3dPresentation for the Leumas game engine: the ECS-to-Object3D bridge, pointer-lock controllers and camera rigs, asset loading, and debug draw. Browser only â€” the simulation kernel is...68 exportsused by 3composes 3
@leumas/game-kitThe Leumas game simulation kernel: ECS, fixed-step loop, physics seam, prefabs, defineGame, netcode. Isomorphic — runs identically in the browser and in a Node sim worker. Contains no three.js, no...301 exportsused by 6

@leumas/revenuePrimitive-first revenue factories, settlement sources, offers, channels, and workflow recipes.35 exportscomposes 1
@leumas/runcodeONE seam for running any language from JS - runCode('python'|'rust'|'perl'|..., { code | file }), plus variable crossing: vars become native variables and emit() returns a value, so runs chain across...16 exports
