Prerequisites

Before starting, make sure you have:

• ✅ A 23blocks account (Sign up)
• ✅ Basic knowledge of JavaScript/TypeScript
• ✅ Node.js 18+ installed
• ✅ A Stripe account (for payments)

---

Part 1: Project Setup

1.1 Create Your App

1. Go to app.23blocks.com
2. Click "Create App"
3. Name it: my-elearning-platform
4. Environment: Development
5. Click "Create"

1.2 Add Required Blocks

Navigate to your app's Blocks tab and add these blocks:

Block	Purpose
Auth	User accounts, login, SSO
Onboarding	Welcome flows, activation emails
Files	Video storage, course materials
University	Courses, lessons, progress
Rewards	Badges, points, gamification
Sales	Subscriptions, payments

1.3 Get Your Credentials

From your app's API Keys tab, copy:

APP_ID=app_xxxxxxxxxxxx
API_KEY=sk_live_xxxxxxxxxxxxxxxxxxxxxxxx
BASE_URL=https://api.23blocks.com/v1

1.4 Initialize Your Project

# Create a new project (React example)
npx create-react-app my-elearning-app --template typescript
cd my-elearning-app

# Install the SDK
npm install @23blocks/sdk

# Create environment file
cat > .env << EOF
REACT_APP_BLOCKS_URL=https://api.23blocks.com/v1
REACT_APP_BLOCKS_APP_ID=app_xxxxxxxxxxxx
REACT_APP_BLOCKS_API_KEY=sk_live_xxxxxxxxxxxxxxxxxxxxxxxx
EOF

1.5 Create the Client

Create src/lib/blocks.ts:

import { BlocksClient } from '@23blocks/sdk';

export const blocks = new BlocksClient({
  baseUrl: process.env.REACT_APP_BLOCKS_URL!,
  appId: process.env.REACT_APP_BLOCKS_APP_ID!,
  apiKey: process.env.REACT_APP_BLOCKS_API_KEY!,
});

// For authenticated requests (after login)
export const createAuthenticatedClient = (sessionToken: string) => {
  return new BlocksClient({
    baseUrl: process.env.REACT_APP_BLOCKS_URL!,
    appId: process.env.REACT_APP_BLOCKS_APP_ID!,
    sessionToken,
  });
};

---

Part 2: User Authentication

2.1 Configure the Auth Block

In your dashboard, go to App → Blocks → Auth → Settings:

Setting	Value
Password minimum length	8
Require uppercase	Yes
Require number	Yes
Session duration	7 days
Allow registration	Yes

2.2 Registration Component

Create src/components/auth/Register.tsx:

import { useState } from 'react';
import { blocks } from '../../lib/blocks';

interface RegisterForm {
  email: string;
  password: string;
  firstName: string;
  lastName: string;
}

export function Register() {
  const [form, setForm] = useState<RegisterForm>({
    email: '',
    password: '',
    firstName: '',
    lastName: '',
  });
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    setLoading(true);
    setError(null);

    try {
      const user = await blocks.auth.register({
        email: form.email,
        password: form.password,
        profile: {
          firstName: form.firstName,
          lastName: form.lastName,
        },
      });

      // Redirect to onboarding
      window.location.href = '/onboarding';
    } catch (err: any) {
      setError(err.message || 'Registration failed');
    } finally {
      setLoading(false);
    }
  };

  return (
    <form onSubmit={handleSubmit} className="space-y-4">
      <h2 className="text-2xl font-bold">Create Your Account</h2>

      {error && (
        <div className="bg-red-100 text-red-700 p-3 rounded">
          {error}
        </div>
      )}

      <div className="grid grid-cols-2 gap-4">
        <input
          type="text"
          placeholder="First Name"
          value={form.firstName}
          onChange={(e) => setForm({ ...form, firstName: e.target.value })}
          className="border p-2 rounded"
          required
        />
        <input
          type="text"
          placeholder="Last Name"
          value={form.lastName}
          onChange={(e) => setForm({ ...form, lastName: e.target.value })}

export function Login() {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    setLoading(true);
    setError(null);

    try {
      const session = await blocks.auth.login({ email, password });

      // Store the session token
      localStorage.setItem('session_token', session.token);
      localStorage.setItem('user', JSON.stringify(session.user));

      // Redirect to dashboard
      window.location.href = '/dashboard';
    } catch (err: any) {
      setError(err.message || 'Login failed');
    } finally {
      setLoading(false);
    }

      )}

      <input
        type="email"
        placeholder="Email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
        className="border p-2 rounded w-full"
        required
      />

        type="password"
        placeholder="Password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
        className="border p-2 rounded w-full"
        required
      />

      <button
        type="submit"
        disabled={loading}

import { createContext, useContext, useState, useEffect, ReactNode } from 'react';
import { createAuthenticatedClient } from '../lib/blocks';

interface User {
  id: string;
  email: string;
  profile: {
    firstName: string;
    lastName: string;
  };
}

interface AuthContextType {
  user: User | null;
  client: ReturnType<typeof createAuthenticatedClient> | null;
  loading: boolean;
  logout: () => void;
}

const AuthContext = createContext<AuthContextType | null>(null);

export function AuthProvider({ children }: { children: ReactNode }) {
  const [user, setUser] = useState<User | null>(null);
  const [client, setClient] = useState<ReturnType<typeof createAuthenticatedClient> | null>(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    const token = localStorage.getItem('session_token');
    const userData = localStorage.getItem('user');

    if (token && userData) {
      setUser(JSON.parse(userData));
      setClient(createAuthenticatedClient(token));
    }
    setLoading(false);
  }, []);

  const logout = () => {
    localStorage.removeItem('session_token');
    localStorage.removeItem('user');
    setUser(null);
    setClient(null);
    window.location.href = '/login';
  };

  return (
    <AuthContext.Provider value={{ user, client, loading, logout }}>
      {children}
    </AuthContext.Provider>
  );
}

export const useAuth = () => {
  const context = useContext(AuthContext);
  if (!context) throw new Error('useAuth must be used within AuthProvider');
  return context;
};
