Engine-agnostic core of the IDosGames SDK — HTTP transport, authentication, local cache, 24 feature services, and a typed event bus. It knows nothing about any rendering engine (Three.js, Phaser, React…), so it works in any browser or JS runtime.

Typed end to end. Every backend response is validated at runtime with zod before it reaches your code; the published type declarations are flat and lightweight.
No exceptions on expected failures. Service calls return a discriminated OperationResult<T> ({ ok: true, data } or { ok: false, reason, error }).
One client owns the whole graph. Create it once; reach every service and the local cache from it.

Install

npm install @idosgames/core

Peer runtime deps (zod, decimal.js) are installed automatically.

Quick start

import { createIDosGamesClient, isOk } from "@idosgames/core";
import { BrowserPlatformAdapter } from "@idosgames/core/platform";

const client = createIDosGamesClient({
  titleID: "YOUR_TITLE_ID",
  platform: new BrowserPlatformAdapter(), // storage + platform integration
});

// Authenticate (device id, Telegram, email, Google, or a platform token).
const login = await client.auth.loginWithDeviceID();
if (!isOk(login)) {
  console.error("login failed:", login.reason, login.error);
}

// Call any service — results are discriminated, never thrown.
const res = await client.currency.convert(
  "Virtual",
  "GOLD",
  "Virtual",
  "GEM",
  100,
);
if (isOk(res)) {
  console.log("credited:", res.data.TargetCredited);
}

// Read the local cache and react to changes via the typed event bus.
const off = client.on("currency:converted", (payload) => {
  console.log("balances updated", payload);
});
// later: off();

Versioning

Semantic versioning. While on 0.x the public API is still stabilizing, so breaking changes may land in a minor bump — see CHANGELOG.md. The backend HTTP API version (/api/v2/…) is independent of this package's version.
