abstrak

Client SDK for Abstrak — verified sign-in, code-driven permissions, and per-user data on top of your own Firebase.

npm install abstrak

import { abstrak } from "abstrak";

const gate = abstrak("pk_live_...");

const user = await gate.signIn();        // { id, email }, verified silently
await gate.tag({ role: "student" });      // set from your own app data
if (await gate.is({ role: "admin" })) showAdminPanel();   // cosmetic
await gate.require({ role: "admin" });    // server-enforced; throws AbstrakDenied
await user.data.set({ purchases: 3 });    // per-user store in your Firebase
const profile = await user.data.get();

Sign-in uses Google Identity Services; include its script once on the page:

<script src="https://accounts.google.com/gsi/client" async></script>

API

• abstrak(publicKey, { baseUrl? }) → client
• signIn() → { id, email, data }
• tag(attrs) — set tags on the current user
• is(match) → boolean (cosmetic checks)
• require(match) — throws AbstrakDenied if not satisfied
• user.data.get() / user.data.set(value)
• signOut()
