Potential solution

To implement Google sign-in on the website, we will need to integrate the Google Sign-In SDK on the front end and set up an API endpoint on the back end to handle the authentication process. The front end will capture the Google user's token and send it to the back end, where it will be verified with Google's servers. Upon successful verification, the user will be logged in, and their session will be managed by the application.

How to implement

Front End Changes in App.js

1. Install the react-google-login package.
2. Import the GoogleLogin component.
3. Implement responseGoogle and handleLoginFailure functions to handle the sign-in responses.
4. Add the GoogleLogin component to the App component's return statement with the necessary props.
5. Replace "YOUR_GOOGLE_CLIENT_ID" with the actual Google client ID.

// Step 1: Install the package using npm or yarn as described in the file-level summary.

// Step 2: Import the GoogleLogin component
import { GoogleLogin } from 'react-google-login';

// Step 3: Implement the response handlers
const responseGoogle = (response) => {
  console.log(response);
  // Dispatch an action or make an API call to the backend
};

const handleLoginFailure = (response) => {
  alert('Failed to log in');
};

// Step 4: Add the GoogleLogin component to the App component's return statement
const App = () => {
  return (
    <ChakraProvider>
      {/* ... other components ... */}
      <GoogleLogin
        clientId="YOUR_ACTUAL_GOOGLE_CLIENT_ID"
        buttonText="Login with Google"
        onSuccess={responseGoogle}
        onFailure={handleLoginFailure}
        cookiePolicy={'single_host_origin'}
      />
    </ChakraProvider>
  );
};

// Step 5: Replace the placeholder with the actual client ID

Back End Changes in heyatNaminApi.js

1. Define a new mutation for Google sign-in.
2. Send the Google sign-in token to the backend server.

// Import createApi and fetchBaseQuery from RTK Query
import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

export const heyatNamineApi = createApi({
  reducerPath: 'heyatNamineApi',
  baseQuery: fetchBaseQuery({ baseUrl: 'https://heyatnamineapi.co/api/v2/' }),
  endpoints: (builder) => ({
    // ... other endpoints ...
    // Step 1: Define a new mutation for Google sign-in
    googleSignIn: builder.mutation({
      query: (googleToken) => ({
        url: 'auth/google',
        method: 'POST',
        body: { token: googleToken },
      }),
    }),
  }),
});

// Step 2: Export the new mutation hook
export const { useGoogleSignInMutation } = heyatNamineApi;

Redux State Management in mainDataSlice.js

1. Define an async thunk for the Google sign-in process.
2. Add new cases to the extraReducers to handle the sign-in process states.
3. Add a user field to the state to store sign-in information.

// Import necessary functions from Redux Toolkit
import { createSlice, createAsyncThunk } from '@reduxjs/toolkit';
import { heyatNamineApi } from '../app/heyatNaminApi';

// Step 1: Define an async thunk for the Google sign-in process
export const signInWithGoogle = createAsyncThunk(
  'mainData/signInWithGoogle',
  async (googleUser) => {
    const response = await heyatNamineApi.googleSignIn(googleUser);
    return response.data;
  }
);

// Step 2: Update the mainDataSlice to handle Google sign-in
const mainDataSlice = createSlice({
  name: 'mainData',
  initialState: {
    // ... other state fields ...
    user: null, // Step 3: Add a user field to the state
  },
  reducers: {
    // ... other reducers ...
  },
  extraReducers: (builder) => {
    builder
      // ... other cases ...
      .addCase(signInWithGoogle.pending, (state) => {
        state.status = 'loading';
      })
      .addCase(signInWithGoogle.fulfilled, (state, action) => {
        state.status = 'succeeded';
        state.user = action.payload; // Store user data
      })
      .addCase(signInWithGoogle.rejected, (state, action) => {
        state.status = 'failed';
        state.error = action.error.message;
      });
  },
});

// Export the reducer and any actions or selectors needed
export const { reducer } = mainDataSlice;
export default reducer;

By implementing these changes, the application will be able to handle Google sign-in on both the front end and the back end, allowing users to log in using their Google accounts.

Changes on heyatnamine/src/App.js

To add a Google sign-in button component and handle the sign-in flow on the front end in the `App.js` file, follow these steps: 1. Install the necessary npm package for Google sign-in integration. You will need to add the Google Sign-In SDK to your project. This can be done by running `npm install react-google-login` or `yarn add react-google-login` in your project directory. 2. Import the Google Login component from the installed package at the top of your `App.js` file: ```javascript import { GoogleLogin } from 'react-google-login'; ``` 3. Create a function to handle the successful sign-in response. This function will receive the user's information from Google: ```javascript const responseGoogle = (response) => { console.log(response); // Here you would typically dispatch an action to your Redux store // or make an API call to your backend with the response token }; ``` 4. Create a function to handle sign-in failures: ```javascript const handleLoginFailure = (response) => { alert('Failed to log in'); }; ``` 5. Add the `GoogleLogin` component to your `App` component's return statement. You will need to provide your Google client ID and the response handlers: ```javascript const App = () => { return ( {/* Add the GoogleLogin component here */} ); }; ``` 6. Replace `"YOUR_GOOGLE_CLIENT_ID"` with the actual client ID you obtain from the Google Developer Console. 7. Ensure that you handle the sign-in data securely and responsibly, following best practices for authentication and state management. 8. Test the Google sign-in flow to make sure it works as expected and that any sign-in data is properly managed in your application's state. By following these steps, you will have added a Google sign-in button to your application and handled the sign-in flow on the front end. Remember to handle the backend part of the authentication in the `heyatnamine/src/app/heyatNaminApi.js` file and update the Redux state in `heyatnamine/src/redux/mainDataSlice.js`.

Changes on heyatnamine/package.json

To integrate Google Sign-In into the front end of the application, we need to install a package that provides the necessary functionality to interact with Google's authentication services. For React applications, a common choice is the `react-google-login` package. Here's a practical proposal to solve the task for the `package.json` file: 1. Install the `react-google-login` package by running the following command in the terminal at the root of the project: ```sh npm install react-google-login ``` 2. After the installation is complete, the `package.json` file should be automatically updated to include the new dependency. Verify that the `dependencies` section of `package.json` now contains `"react-google-login": "^x.x.x"`, where `x.x.x` is the version number of the package that was installed. 3. Save the changes to the `package.json` file. 4. Commit the updated `package.json` and the corresponding `package-lock.json` files to the project's version control system. By following these steps, the necessary package for Google Sign-In integration will be installed, and the application will be ready for the next steps of implementing the sign-in button component and handling the sign-in flow on the front end.

Changes on heyatnamine/src/redux/mainDataSlice.js

To update the `mainDataSlice.js` file to handle the state changes related to Google sign-in, we need to add new actions and possibly a new async thunk if we want to handle the sign-in process asynchronously with Redux. Here's a practical proposal for the changes: 1. Define a new async thunk for the Google sign-in process. 2. Add new cases to the `extraReducers` to handle the pending, fulfilled, and rejected states of the Google sign-in process. 3. Add new actions for any synchronous state changes that might be needed, such as setting the user's sign-in status. Here's how the updated `mainDataSlice.js` might look: ```javascript import { createSlice, createAsyncThunk, createEntityAdapter, } from "@reduxjs/toolkit"; import { heyatNamineApi } from "../app/heyatNaminApi"; // Existing code... // Define an async thunk for the Google sign-in process export const signInWithGoogle = createAsyncThunk( "mainData/signInWithGoogle", async (googleUser) => { // Assuming heyatNamineApi has a method to handle Google sign-in const response = await heyatNamineApi.signInWithGoogle(googleUser); return response.data; } ); // Update the mainDataSlice to handle Google sign-in const mainDataSlice = createSlice({ name: "mainData", initialState: mainDataAdapter.getInitialState({ status: "idle", error: null, user: null, // Add a user field to the state to store sign-in information }), reducers: { // You can add synchronous actions here if needed }, extraReducers: (builder) => { builder // Existing cases... .addCase(signInWithGoogle.pending, (state) => { state.status = "loading"; }) .addCase(signInWithGoogle.fulfilled, (state, action) => { state.status = "succeeded"; state.user = action.payload; // Store the user data on successful sign-in }) .addCase(signInWithGoogle.rejected, (state, action) => { state.status = "failed"; state.error = action.error.message; }); }, }); // Export the reducer and any actions or selectors you might need export const { selectAll: selectAllMainData, selectById: selectMainDataById } = mainDataAdapter.getSelectors((state) => state.mainData); export const { reducer, actions } = mainDataSlice; export default mainDataSlice.reducer // Example usage of the signInWithGoogle async thunk in a component: // dispatch(signInWithGoogle(googleUser)); ``` In this updated code, we've added a new async thunk `signInWithGoogle` to handle the Google sign-in process. We've also added new cases to the `extraReducers` to handle the different states of the async thunk. Additionally, we've added a `user` field to the initial state to store the user's sign-in information. Please note that the actual implementation of `heyatNamineApi.signInWithGoogle` would need to be defined in the `heyatNaminApi.js` file, which is outside the scope of this task.

Changes on heyatnamine/src/app/heyatNaminApi.js

To solve the task of adding a Google sign-in button component and handling the sign-in flow on the front end, we need to create a new API endpoint in the `heyatNamineApi.js` file that will communicate with the Google Identity Platform and our backend server. Here is a practical proposal for implementing the Google sign-in API endpoint: 1. Define a new mutation in the `endpoints` section of the `heyatNamineApi` object. This mutation will be responsible for sending the Google sign-in token (obtained from the front end after the user signs in with Google) to the backend server. 2. The backend server will then need to verify the token with Google's servers and create a new user session or retrieve an existing one. 3. Once the token is verified, the backend server will respond with the appropriate user data or error message. Here's how you can add the new endpoint: ```javascript // Add this import to handle Google sign-in import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react'; export const heyatNamineApi = createApi({ reducerPath: 'heyatNamineApi', baseQuery: fetchBaseQuery({ baseUrl: 'https://heyatnamineapi.co/api/v2/' }), endpoints: (builder) => ({ // Existing endpoints getPosts: builder.query({ query: () => 'posts', }), createPost: builder.mutation({ query: (newPost) => ({ url: 'posts', method: 'POST', body: newPost, }), }), // New endpoint for Google sign-in googleSignIn: builder.mutation({ query: (googleToken) => ({ url: 'auth/google', method: 'POST', body: { token: googleToken }, }), }), }), }); // Export the new mutation hook export const { useGetPostsQuery, useCreatePostMutation, useGoogleSignInMutation } = heyatNamineApi; ``` In the above code, we've added a new mutation called `googleSignIn`. This mutation takes a `googleToken` as an argument and sends it to the `auth/google` endpoint on the backend server using a POST request. The backend server (not covered in this file) will need to handle the `auth/google` endpoint by verifying the token with Google and responding accordingly. Remember to handle the response on the front end, including any error handling and state updates that may be necessary after the user signs in with Google.
