React Integration for apps-client

Goal: Provide developers with a guide on integrating the apps-client library with React applications.

Outline:

• Component Structure:
  • AppClient Component: A React component providing the core integration point for interacting with the apps-client library.
    • Props:
      • appId (String): Unique identifier for the application.
      • options (Object): Configuration options for the client library.
      • onInitialized (Function): Callback function triggered when the client library initializes successfully.
    • Methods:
      • initialize(): Starts the client library initialization process.
      • isAuthenticated(): Checks if the user is currently authenticated.
      • logout(): Logs the user out of the application.
      • Event Handlers:
        • onLogin: Callback function triggered when a user successfully logs in.
        • onLogout: Callback function triggered when a user logs out.
        • onError: Callback function triggered when an error occurs during client initialization.
    • Example:

    import React, { useState, useEffect } from 'react';
              import { AppClient } from 'apps-client';
              
              function MyComponent() {
                const [isAuthenticated, setIsAuthenticated] = useState(false);
                const [client, setClient] = useState(null);
              
                useEffect(() => {
                  const newClient = new AppClient({
                    appId: 'your-app-id',
                    options: {
                      // Configuration options for the client library
                    },
                    onInitialized: () => {
                      setIsAuthenticated(client.isAuthenticated());
                      setClient(client);
                    },
                  });
                  newClient.initialize();
                }, []);
              
                return (
                  <div>
                    {isAuthenticated && (
                      <button onClick={() => client.logout()}>Logout</button>
                    )}
                    {!isAuthenticated && (
                      <button onClick={() => client.login()}>Login</button>
                    )}
                  </div>
                );
              }
              

• Hooks:
  • useCallback Hook: This hook is used to create memoized callbacks that can be passed as event handlers.
    • Example:

    import React, { useCallback } from 'react';
              import { AppClient } from 'apps-client';
              
              function MyComponent() {
                const client = new AppClient({
                  appId: 'your-app-id',
                  options: {
                    // Configuration options for the client library
                  },
                });
              
                const handleLogin = useCallback(() => {
                  client.login();
                }, []);
              
                return (
                  <button onClick={handleLogin}>Login</button>
                );
              }
              

• Event Handling:
  • onLogin and onLogout Events: The AppClient component emits onLogin and onLogout events when these actions are triggered. These events can be used to update the application state and provide feedback to the user.
    • Example:

    import React, { useState } from 'react';
              import { AppClient } from 'apps-client';
              
              function MyComponent() {
                const [isLoggedIn, setIsLoggedIn] = useState(false);
              
                const client = new AppClient({
                  appId: 'your-app-id',
                  options: {
                    // Configuration options for the client library
                  },
                  onLogin: () => {
                    setIsLoggedIn(true);
                  },
                  onLogout: () => {
                    setIsLoggedIn(false);
                  },
                });
              
                return (
                  <div>
                    {isLoggedIn && <p>You are logged in!</p>}
                    {!isLoggedIn && <p>You are not logged in.</p>}
                  </div>
                );
              }
              

• User Interaction Patterns:
  • Authentication: The apps-client library provides mechanisms for user authentication. Developers can use these mechanisms to manage user login, logout, and session management within their React application.
  • API Integration: The library enables access to application-specific APIs and data. React components can interact with these APIs to retrieve, manipulate, and display data.
  • Error Handling: The library provides error handling mechanisms to manage and display errors gracefully. Developers should handle errors accordingly to provide a consistent user experience.
