@oneclient/sdk

The typed client behind OneClient. It covers project auth, policy-controlled data, parameterized SQL, object storage and S3 multipart uploads, KV, queues and schedules, transactional email, managed/BYOK AI, product analytics, deployments, domains, billing, GitHub, and recovery workflows.

npm install @oneclient/sdk

import { createServerClient } from "@oneclient/sdk";

export default {
  async fetch(_request: Request, env: Env) {
    const one = createServerClient(env);
    await one.analytics.track([
      { name: "workspace.created", occurredAt: new Date().toISOString(), properties: {} },
    ]);
    return Response.json(await one.kv.get("release-flags"));
  },
};

For the SDK and CLI in one install, use oneclient. Read the five-minute quickstart or the generated API reference.

Expo magic-link callbacks

The Better Auth Expo plugin persists OTP responses automatically. For an email magic link, consume the approved app-scheme callback with consumeExpoMagicLinkCallback, then refresh the Better Auth session. The helper validates the configured scheme and Better Auth cookie names, writes only to the provided secure-storage adapter, and returns a URL with the signed cookie removed.

import { consumeExpoMagicLinkCallback } from "@oneclient/sdk";

const callback = await consumeExpoMagicLinkCallback(url, {
  scheme: "myapp",
  storagePrefix: "myapp",
  storage: SecureStore,
});
if (callback.handled) await auth.getSession();
