@jakuta-inc/auth

TypeScript auth lifecycle primitives for Jakuta-family web apps.

The package mirrors the Dart jakuta_auth boundary: auth state and lifecycle outcomes are sealed unions, token storage is injected through @jakuta-inc/token-storage, and login/restore/logout return named branches instead of nullable session values.

import { JakutaAuthController } from "@jakuta-inc/auth";
import { MemoryJakutaTokenStorage, bearerTokenFromText } from "@jakuta-inc/token-storage";

const token = bearerTokenFromText("session-token");
if (token.kind === "accepted") {
  const auth = new JakutaAuthController({
    tokenStorage: new MemoryJakutaTokenStorage(),
    restoreUserFromToken: async () => ({ kind: "restored", authenticatedUser: { id: "1" } }),
    loginForToken: async () => ({ kind: "accepted", bearerToken: token.bearerToken }),
    registerForToken: async () => ({ kind: "accepted", bearerToken: token.bearerToken }),
  });
}
