🚀 Quick Start

Installation

pnpm add @oauth-kit/sdk
# or
npm install @oauth-kit/sdk

Basic Usage

import { createClient, SQLiteStore } from "@oauth-kit/sdk";

// Create OAuth client
const client = createClient({
  provider: "google",
  clientId: process.env.GOOGLE_CLIENT_ID!,
  clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
  redirectUri: "http://localhost:8787/callback",
  store: new SQLiteStore("tokens.db")
});

// Initialize and authorize
await client.init();
await client.authorize();

// Make authenticated requests
const response = await client.request("https://www.googleapis.com/oauth2/v2/userinfo");
const user = await response.json();
console.log(user);
