Implement login and user sign-up functionality for a WordPress WooCommerce site in React Native

Implement login and user sign-up functionality for a WordPress WooCommerce site in React Native

Hello guys how are you? welcome back to my blog therichpost.com. Guys today in this post we are going to implement login and user sign-up functionality for a WordPress WooCommerce site in React Native, Guy we can use the WooCommerce REST API along with WordPress REST API for authentication. Here’s is the code snippet:

1. Setup WordPress REST API Authentication:

Guys WordPress provides the JWT Authentication plugin that we can use to generate tokens for login and sign-up. First, install and activate the JWT Authentication plugin in your WordPress site.

define('JWT_AUTH_SECRET_KEY', 'your-top-secret-key');
define('JWT_AUTH_CORS_ENABLE', true);

2. Create User Sign-Up API:

Guys we can handle the user registration process using the WordPress API wp-json/wp/v2/users. Use POST requests to create new users. This API requires administrator credentials, so ensure you use proper permissions and security measures.

Example API call for user registration:

POST https://yourdomain.com/wp-json/wp/v2/users
Authorization: Basic base64_encode("username:password")
Body:
{
    "username": "newuser",
    "email": "newuser@example.com",
    "password": "password123"
}

3. Handle User Login:

Guys we can handle user login by sending a POST request to the /wp-json/jwt-auth/v1/token endpoint.

Example login API call:

POST https://yourdomain.com/wp-json/jwt-auth/v1/token
Body:
{
    "username": "yourusername",
    "password": "yourpassword"
}

This will return a JWT token that you can use to authenticate the user for further requests.

4. React Native Implementation:

Guys now install the necessary libraries to handle API calls in React Native:

npm install axios react-native-async-storage/async-storage

Example Code for Login:

import axios from 'axios';
import AsyncStorage from '@react-native-async-storage/async-storage';

// Login function
const login = async (username, password) => {
  try {
    const response = await axios.post('https://yourdomain.com/wp-json/jwt-auth/v1/token', {
      username: username,
      password: password
    });
    const token = response.data.token;
    // Store the token in AsyncStorage for future use
    await AsyncStorage.setItem('userToken', token);
    console.log('Login successful:', token);
  } catch (error) {
    console.error('Login failed:', error.response.data);
  }
};

Example Code for User Registration:

import axios from 'axios';

const registerUser = async (username, email, password) => {
  try {
    const response = await axios.post('https://yourdomain.com/wp-json/wp/v2/users', {
      username: username,
      email: email,
      password: password
    }, {
      headers: {
        Authorization: 'Basic ' + btoa('admin_username:admin_password'), // Use admin credentials here
      },
    });
    console.log('User registration successful:', response.data);
  } catch (error) {
    console.error('User registration failed:', error.response.data);
  }
};

5. Handling Authenticated Requests:

Guys After login, we can use the stored JWT token to make authenticated requests to the WooCommerce or WordPress API by attaching it to the headers.

const getUserDetails = async () => {
  const token = await AsyncStorage.getItem('userToken');
  const response = await axios.get('https://yourdomain.com/wp-json/wp/v2/users/me', {
    headers: {
      Authorization: `Bearer ${token}`
    }
  });
  console.log('User details:', response.data);
};

6. Logout:

Guy for logout, we can simply remove the token from AsyncStorage.

const logout = async () => {
  await AsyncStorage.removeItem('userToken');
  console.log('User logged out');
};

This setup will help you implement login, sign-up, and authenticated requests in your React Native app for WooCommerce and WordPress.

Guys here is also Complete Demo for React Native Login and Signup Forms

Here’s a complete React Native demo with a login and signup form for WordPress WooCommerce.

Dependencies:

Guys Install necessary packages before starting:

npm install axios react-native-async-storage/async-storage

Complete Demo for React Native Login and Signup Forms

import React, { useState } from 'react';
import { View, TextInput, Button, Text, Alert } from 'react-native';
import AsyncStorage from '@react-native-async-storage/async-storage';
import axios from 'axios';

// API Base URL
const API_URL = 'https://yourdomain.com/wp-json';

// Authentication component
const AuthForm = () => {
  const [username, setUsername] = useState('');
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const [isLogin, setIsLogin] = useState(true); // Toggle between login and signup

  // Login function
  const login = async () => {
    try {
      const response = await axios.post(`${API_URL}/jwt-auth/v1/token`, {
        username: username,
        password: password,
      });
      const token = response.data.token;
      // Store token in AsyncStorage
      await AsyncStorage.setItem('userToken', token);
      Alert.alert('Success', 'Login successful');
    } catch (error) {
      console.error('Login failed:', error.response.data);
      Alert.alert('Error', 'Login failed. Please try again.');
    }
  };

  // Signup function
  const register = async () => {
    try {
      const response = await axios.post(
        `${API_URL}/wp/v2/users`,
        {
          username: username,
          email: email,
          password: password,
        },
        {
          headers: {
            Authorization: 'Basic ' + btoa('admin_username:admin_password'), // Replace with admin credentials
          },
        }
      );
      Alert.alert('Success', 'User registration successful');
    } catch (error) {
      console.error('Registration failed:', error.response.data);
      Alert.alert('Error', 'Registration failed. Please try again.');
    }
  };

  // Toggle between login and signup
  const toggleAuthMode = () => {
    setIsLogin(!isLogin);
  };

  return (
    <View style={{ padding: 20 }}>
      <Text style={{ fontSize: 24, textAlign: 'center', marginBottom: 20 }}>
        {isLogin ? 'Login' : 'Sign Up'}
      </Text>

      <TextInput
        placeholder="Username"
        value={username}
        onChangeText={setUsername}
        style={{ borderWidth: 1, padding: 10, marginBottom: 10 }}
      />

      {!isLogin && (
        <TextInput
          placeholder="Email"
          value={email}
          onChangeText={setEmail}
          style={{ borderWidth: 1, padding: 10, marginBottom: 10 }}
        />
      )}

      <TextInput
        placeholder="Password"
        value={password}
        onChangeText={setPassword}
        secureTextEntry
        style={{ borderWidth: 1, padding: 10, marginBottom: 10 }}
      />

      <Button title={isLogin ? 'Login' : 'Sign Up'} onPress={isLogin ? login : register} />

      <Text
        style={{ marginTop: 20, textAlign: 'center', color: 'blue' }}
        onPress={toggleAuthMode}
      >
        {isLogin ? 'No account? Sign up' : 'Have an account? Login'}
      </Text>
    </View>
  );
};

export default AuthForm;

Key Features of This Demo:

  1. Login & Signup Forms:
  • When in login mode, the email field is hidden.
  • The form switches between login and signup using the isLogin state.
  1. Handling API Requests:
  • Login API sends a request to jwt-auth/v1/token.
  • Signup API sends a request to wp/v2/users (admin credentials are required in headers).
  1. AsyncStorage:
  • Stores the JWT token on successful login.
  1. UI:
  • Simple UI with text inputs for username, email, and password.
  • A button to submit the form for either login or signup.
  • A toggle link for switching between login and signup.

Things to Remember:

  • Replace https://yourdomain.com with your WordPress site URL.
  • Use appropriate admin credentials in the signup request.
  • Secure the API: Ensure the API is secured to prevent misuse.

This should give you a fully functional login and signup system in your React Native app connected to a WooCommerce WordPress site!
