Build a User Dashboard & History Page: Your Guide to a Personalized Summary Hub

Hey guys! 👋 Ready to dive into creating a super cool feature for StudyBuddy-AI? We're talking about building a User Dashboard and History Page. This is where our users can chill and check out all their past summaries. Think of it as their personalized summary hub, making it easy to revisit and learn from their study materials. This project will involve a new protected route, fetching data from Firebase, and displaying everything in a user-friendly way. Let's break down the tasks, making sure it's all smooth sailing!

Setting the Stage: Understanding the User Story and Acceptance Criteria

Before we jump into the code, let's get on the same page about what we're building. The user story is straightforward: As a logged-in user, I want to go to a "My Dashboard" page and see a list of all my saved summaries. Simple, right? But what does this mean in terms of what we need to actually do? That's where the Acceptance Criteria (AC) come in. They are the specific tasks that we need to complete to make sure the user story is a success. Let's break down each AC point to make sure we've got everything covered.

Task Breakdown: What Needs to Be Done

  • Create a new protected route/page in React (e.g., /dashboard): First things first, we need a place for this dashboard to live. This involves setting up a new route in our React application, making it accessible at something like /dashboard. But here's the kicker: it needs to be protected. This means that only logged-in users should be able to access it. If someone's not logged in and tries to go to /dashboard, they should be redirected to the login page. This is super important for security and to make sure that users can only see their summaries. We'll likely use a component like PrivateRoute to handle this. Essentially, PrivateRoute checks if a user is authenticated and, if not, redirects them to the login page. If they are authenticated, it renders the dashboard component.

  • Use the Firebase SDK to query Firestore for all summaries belonging to the current userId: Next up, we need to fetch the data. We're storing the summaries in Firestore, which is a NoSQL database provided by Firebase. We'll use the Firebase SDK to query Firestore and get all the summaries that belong to the current user. How do we know which summaries belong to which user? Each summary in our database will be associated with a userId. We'll use the userId of the currently logged-in user to filter the summaries. This ensures that each user only sees their summaries, keeping things private and personalized.

  • Use onSnapshot for real-time updates: This is where things get really cool. Instead of just fetching the summaries once, we want them to update in real-time. This means that if a user saves a new summary, it should instantly appear on their dashboard without them having to refresh the page. We'll use Firestore's onSnapshot feature for this. onSnapshot listens for changes in the data and automatically updates the data in our component. This is a powerful feature that makes our dashboard feel dynamic and responsive.

  • Display the summaries as a list or cards (e.g., "Lecture 1 Summary - PDF"): Once we've got the data, we need to display it in a user-friendly way. We can choose to display the summaries as a simple list or as cards, each representing a summary. The design is up to us, but the goal is to make it easy for users to quickly scan and find the summaries they're looking for. Each entry should clearly indicate what the summary is about. Think about including the file name (e.g., "Lecture 1 Summary - PDF") and maybe the date the summary was created.

  • Add a search bar to filter the history by fileName: Finally, we want to make it easy for users to find a specific summary, even if they have a lot of them. A search bar will allow them to filter the summaries by the file name. As the user types in the search bar, the list of summaries should update in real-time, showing only the summaries that match the search query. This feature significantly improves the usability of the dashboard, especially as the number of summaries grows.

Let's Get Started: Coding the User Dashboard

Alright, let's roll up our sleeves and get coding! We will break down each task in detail, providing code snippets and explanations.

1. Creating the Protected Route and Page

The first step is to create the /dashboard route and make sure it's protected. We'll use React Router for routing and create a PrivateRoute component to handle authentication. Here's a basic example:

// PrivateRoute.js
import React, { useContext } from 'react';
import { Route, Redirect } from 'react-router-dom';
import { AuthContext } from './AuthContext'; // Assuming you have an AuthContext

const PrivateRoute = ({ component: Component, ...rest }) => {
  const { user } = useContext(AuthContext);

  return (
    <Route
      {...rest}
      render={(props) =>
        user ? <Component {...props} /> : <Redirect to="/login" />
      }
    />
  );
};

export default PrivateRoute;

// App.js
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import PrivateRoute from './PrivateRoute';
import Dashboard from './Dashboard';
import Login from './Login';

function App() {
  return (
    <Router>
      <Switch>
        <Route path="/login" component={Login} />
        <PrivateRoute path="/dashboard" component={Dashboard} />
        {/* Other routes */} 
      </Switch>
    </Router>
  );
}

export default App;

In this setup, PrivateRoute checks if the user is authenticated using the AuthContext. If the user is logged in (user is not null), it renders the Dashboard component. Otherwise, it redirects the user to the /login page.

2. Fetching Summaries from Firestore

Next, we need to fetch the summaries from Firestore. We'll use the Firebase SDK to query the database. First, make sure you have the Firebase SDK set up in your project. Then, in your Dashboard component:

// Dashboard.js
import React, { useState, useEffect, useContext } from 'react';
import { AuthContext } from './AuthContext';
import { db } from './firebase'; // Your Firebase configuration

function Dashboard() {
  const [summaries, setSummaries] = useState([]);
  const [search, setSearch] = useState('');
  const { user } = useContext(AuthContext);

  useEffect(() => {
    if (!user) return; // Wait for user to be available

    const unsubscribe = db.collection('summaries')
      .where('userId', '==', user.uid)
      .orderBy('createdAt', 'desc') // Optional: Order by creation date
      .onSnapshot((snapshot) => {
        const summaryList = snapshot.docs.map(doc => ({
          id: doc.id,
          ...doc.data()
        }));
        setSummaries(summaryList);
      });

    return () => unsubscribe(); // Cleanup on unmount
  }, [user]);

  const filteredSummaries = summaries.filter(summary =>
    summary.fileName.toLowerCase().includes(search.toLowerCase())
  );

  return (
    <div>
      <h1>My Dashboard</h1>
      <input
        type="text"
        placeholder="Search by file name"
        onChange={e => setSearch(e.target.value)}
      />
      <ul>
        {filteredSummaries.map(summary => (
          <li key={summary.id}>{summary.fileName}</li>
        ))}
      </ul>
    </div>
  );
}

export default Dashboard;

This code does the following:

  • Imports Necessary Modules: Imports useState, useEffect, useContext from React, AuthContext, and your Firebase configuration (db).
  • Sets Up State: Uses useState to manage the summaries array and the search term.
  • Fetches Summaries with useEffect: The useEffect hook runs when the component mounts and when the user changes. It queries Firestore for summaries where the userId matches the current user's ID. It uses onSnapshot to listen for real-time updates and automatically updates the summaries state.
  • Orders by createdAt: The code includes an optional .orderBy('createdAt', 'desc') to sort summaries by creation date, displaying the most recent summaries first.
  • Filters Summaries: Implements the search functionality by filtering the summaries array based on the search input.
  • Renders Summaries: Maps over the filteredSummaries and renders each summary as a list item, including the fileName.

3. Displaying Summaries and Adding a Search Bar

The final step is to display the summaries and add a search bar. We'll add an input field for the search bar and then use the filter method to filter the summaries based on the search input. The displayed summaries are then rendered as a list or cards.

function Dashboard() {
  // ... (previous code)

  return (
    <div>
      <h1>My Dashboard</h1>
      <input
        type="text"
        placeholder="Search by file name"
        onChange={e => setSearch(e.target.value)}
      />
      <ul>
        {filteredSummaries.map(summary => (
          <li key={summary.id}>{summary.fileName}</li>
        ))}
      </ul>
    </div>
  );
}
