Initial prompt

---

Write a web app for task tracking using ReactJS and SQLite. It should be accessible and formatted well on tablet and mobile browsers. The unit of tracking should be an instance of the task, and a default amount of time assigned per instance. That instance time in minutes may be updated for a specific instance at a date and times.

A plus button on the bottom right of the page should initiate a new task at the current date and time, with a drop down menu for the task type to choose. One option in the task type drop down should be a “New Task”

The default view on tablet or desktop should be a current month view with a task type and count for each day that already has tasks added. The default view on mobile should be a current week view with the same accumulated task indicators on each day. Clicking on the day in either view should pull up a single day view with the tasks associated with that day at their respective times on a hourly schedule. A back arrow in the top left should return to a week or month view.

The tasks should include a user label as well, so the database can reach multiple users at once. The interface can allow any user to assign a person to a task from a drop down menu that includes any existing user as well as a “New User”.

A separate tab or view should allow analysis of tasks completed, with configurable filtering on user, task type, and date range. A summary of task counts and time for tasks should be updated with each change to the filtering settings. The default Analysis page should pull up the prior view, or if there is no known prior analysis view then the current month and all tasks completed for all users.

Default tasks to start the app with include “Empty dishwasher”, “Fill dishwasher”, “Fill laundry”, “Fold laundry”, and “Cook meal” with a description text window for the meal.

I'd be happy to help you create a web app for task tracking using ReactJS and SQLite with the features you've described. This is a complex project that will require multiple components and careful planning. Let's break it down and create a basic structure for the app.

import React, { useState, useEffect } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Calendar from './components/Calendar';
import DayView from './components/DayView';
import Analysis from './components/Analysis';
import NewTaskButton from './components/NewTaskButton';
import { initializeDatabase, getTasks, addTask, updateTask } from './database';

const App = () => {
  const [tasks, setTasks] = useState([]);
  const [users, setUsers] = useState([]);
  const [taskTypes, setTaskTypes] = useState([
    'Empty dishwasher',
    'Fill dishwasher',
    'Fill laundry',
    'Fold laundry',
    'Cook meal'
  ]);

  useEffect(() => {
    initializeDatabase();
    fetchTasks();
    fetchUsers();
  }, []);

  const fetchTasks = async () => {
    const fetchedTasks = await getTasks();
    setTasks(fetchedTasks);
  };

  const fetchUsers = async () => {
    // Implement fetching users from the database
  };

  const handleAddTask = async (newTask) => {
    await addTask(newTask);
    fetchTasks();
  };

  const handleUpdateTask = async (updatedTask) => {
    await updateTask(updatedTask);
    fetchTasks();
  };

  return (
    <Router>
      <div className="app">
        <Switch>
          <Route exact path="/" component={() => <Calendar tasks={tasks} />} />
          <Route path="/day/:date" component={DayView} />
          <Route path="/analysis" component={Analysis} />
        </Switch>
        <NewTaskButton onAddTask={handleAddTask} taskTypes={taskTypes} users={users} />
      </div>
    </Router>
  );
};

export default App;

This is a basic structure for the main App component. It sets up the routing and main state management for the application. Here's a breakdown of the components and features:

1. Main App component:

   • Manages the overall state (tasks, users, taskTypes)
   • Sets up routing for different views
   • Initializes the database and fetches initial data

2. Calendar component (to be implemented):

   • Will display month view on tablet/desktop and week view on mobile
   • Shows task counts for each day

3. DayView component (to be implemented):

   • Will display tasks for a specific day in an hourly schedule

4. Analysis component (to be implemented):

   • Will allow filtering and analysis of completed tasks

5. NewTaskButton component (to be implemented):

   • Floating action button for adding new tasks

6. Database functions (to be implemented in a separate file):

   • Initialize SQLite database
   • CRUD operations for tasks and users

To proceed with the implementation, we need to create the individual components and set up the SQLite database. Would you like me to focus on a specific component or the database setup next?

Setup the calendar component next

Certainly, I'll create the Calendar component for you. This component will handle both the month view for tablet/desktop and the week view for mobile devices. We'll use CSS media queries to switch between these views based on screen size.

import React, { useState, useEffect } from 'react';
import { useHistory } from 'react-router-dom';
import { format, startOfWeek, endOfWeek, startOfMonth, endOfMonth, eachDayOfInterval, isSameMonth, isSameDay } from 'date-fns';

const Calendar = ({ tasks }) => {
  const [currentDate, setCurrentDate] = useState(new Date());
  const [calendarDays, setCalendarDays] = useState([]);
  const [view, setView] = useState('month');
  const history = useHistory();

  useEffect(() => {
    const handleResize = () => {
      setView(window.innerWidth < 768 ? 'week' : 'month');
    };
    window.addEventListener('resize', handleResize);
    handleResize();
    return () => window.removeEventListener('resize', handleResize);
  }, []);

  useEffect(() => {
    const days = view === 'month'
      ? getMonthDays(currentDate)
      : getWeekDays(currentDate);
    setCalendarDays(days);
  }, [currentDate, view]);

  const getMonthDays = (date) => {
    const start = startOfMonth(date);
    const end = endOfMonth(date);
    return eachDayOfInterval({ start, end });
  };

  const getWeekDays = (date) => {
    const start = startOfWeek(date);
    const end = endOfWeek(date);
    return eachDayOfInterval({ start, end });
  };

  const getTaskCountForDay = (day) => {
    return tasks.filter(task => isSameDay(new Date(task.date), day)).length;
  };

  const handleDayClick = (day) => {
    history.push(`/day/${format(day, 'yyyy-MM-dd')}`);
  };

  const handlePrevious = () => {
    setCurrentDate(prevDate => view === 'month'
      ? new Date(prevDate.getFullYear(), prevDate.getMonth() - 1, 1)
      : new Date(prevDate.getFullYear(), prevDate.getMonth(), prevDate.getDate() - 7)
    );
  };

  const handleNext = () => {
    setCurrentDate(prevDate => view === 'month'
      ? new Date(prevDate.getFullYear(), prevDate.getMonth() + 1, 1)
      : new Date(prevDate.getFullYear(), prevDate.getMonth(), prevDate.getDate() + 7)
    );
  };

  return (
    <div className="calendar">
      <div className="calendar-header">
        <button onClick={handlePrevious}>&lt;</button>
        <h2>{format(currentDate, view === 'month' ? 'MMMM yyyy' : 'MMMM dd, yyyy')}</h2>
        <button onClick={handleNext}>&gt;</button>
      </div>
      <div className={`calendar-grid ${view}`}>
        {calendarDays.map(day => (
          <div
            key={day.toISOString()}
            className={`calendar-day ${!isSameMonth(day, currentDate) ? 'other-month' : ''}`}
            onClick={() => handleDayClick(day)}
          >
            <span className="day-number">{format(day, 'd')}</span>
            <span className="task-count">{getTaskCountForDay(day)}</span>
          </div>
        ))}
      </div>
    </div>
  );
};

export default Calendar;

This Calendar component implements the following features:

1. Responsive design: It switches between month and week views based on screen size.
2. Dynamic calendar generation: It generates the correct days for either a month or week view.
3. Navigation: Users can navigate between months or weeks.
4. Task count display: It shows the number of tasks for each day.
5. Day selection: Clicking on a day navigates to the DayView component.

To make this component work properly, you'll need to add some CSS. Here's a basic CSS structure to get you started:

.calendar {
  max-width: 100%;
  margin: 0 auto;
}

.calendar-header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin-bottom: 1rem;
}

.calendar-grid {
  display: grid;
  gap: 1px;
  background-color: #e0e0e0;
}

.calendar-grid.month {
  grid-template-columns: repeat(7, 1fr);
}

.calendar-grid.week {
  grid-template-columns: repeat(7, 1fr);
}

.calendar-day {
  background-color: white;
  padding: 0.5rem;
  min-height: 100px;
  display: flex;
  flex-direction: column;
  cursor: pointer;
}

.calendar-day:hover {
  background-color: #f0f0f0;
}

.day-number {
  font-weight: bold;
}

.task-count {
  margin-top: auto;
  align-self: flex-end;
  background-color: #007bff;
  color: white;
  border-radius: 50%;
  width: 24px;
  height: 24px;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 0.8rem;
}

.other-month {
  opacity: 0.5;
}

@media (max-width: 768px) {
  .calendar-day {
    min-height: 60px;
  }
}

This CSS provides a basic structure and styling for the Calendar component. It includes:

1. Responsive grid layout for both month and week views
2. Styling for the calendar header, including navigation buttons
3. Individual day styling with hover effects
4. Task count display as a circular badge
5. Responsive adjustments for mobile devices

To use this CSS, you can either include it in your global CSS file or use a CSS-in-JS solution like styled-components.

Next steps:

1. Implement the DayView component to display tasks for a specific day.
2. Create the NewTaskButton component for adding new tasks.
3. Develop the Analysis component for task filtering and analysis.
4. Set up the SQLite database and implement the necessary CRUD operations.

Which part would you like me to focus on next?

Setup the SQLite database next

Certainly, I'll set up the SQLite database for the task tracking app. We'll use the sqlite3 package for Node.js to interact with SQLite. First, we need to create a database file and set up the necessary tables. Then, we'll implement the CRUD operations for tasks and users.

const sqlite3 = require('sqlite3').verbose();
const path = require('path');

const dbPath = path.resolve(__dirname, 'tasktracker.sqlite');

let db;

function openDatabase() {
  return new Promise((resolve, reject) => {
    db = new sqlite3.Database(dbPath, (err) => {
      if (err) reject(err);
      resolve(db);
    });
  });
}

async function initializeDatabase() {
  try {
    await openDatabase();
    await createTables();
    console.log('Database initialized successfully');
  } catch (error) {
    console.error('Error initializing database:', error);
  }
}

function createTables() {
  return new Promise((resolve, reject) => {
    db.run(`
      CREATE TABLE IF NOT EXISTS users (
        id INTEGER PRIMARY KEY AUTOINCREMENT,
        name TEXT NOT NULL
      )
    `, (err) => {
      if (err) reject(err);
      db.run(`
        CREATE TABLE IF NOT EXISTS tasks (
          id INTEGER PRIMARY KEY AUTOINCREMENT,
          user_id INTEGER,
          task_type TEXT NOT NULL,
          description TEXT,
          date TEXT NOT NULL,
          time TEXT NOT NULL,
          duration INTEGER NOT NULL,
          FOREIGN KEY (user_id) REFERENCES users (id)
        )
      `, (err) => {
        if (err) reject(err);
        resolve();
      });
    });
  });
}

async function addTask(task) {
  return new Promise((resolve, reject) => {
    const { user_id, task_type, description, date, time, duration } = task;
    db.run(
      'INSERT INTO tasks (user_id, task_type, description, date, time, duration) VALUES (?, ?, ?, ?, ?, ?)',
      [user_id, task_type, description, date, time, duration],
      function(err) {
        if (err) reject(err);
        resolve(this.lastID);
      }
    );
  });
}

async function getTasks(filters = {}) {
  return new Promise((resolve, reject) => {
    let query = 'SELECT * FROM tasks';
    const whereConditions = [];
    const params = [];

    if (filters.user_id) {
      whereConditions.push('user_id = ?');
      params.push(filters.user_id);
    }
    if (filters.task_type) {
      whereConditions.push('task_type = ?');
      params.push(filters.task_type);
    }
    if (filters.start_date && filters.end_date) {
      whereConditions.push('date BETWEEN ? AND ?');
      params.push(filters.start_date, filters.end_date);
    }

    if (whereConditions.length > 0) {
      query += ' WHERE ' + whereConditions.join(' AND ');
    }

    db.all(query, params, (err, rows) => {
      if (err) reject(err);
      resolve(rows);
    });
  });
}

async function updateTask(taskId, updates) {
  return new Promise((resolve, reject) => {
    const { task_type, description, date, time, duration } = updates;
    db.run(
      'UPDATE tasks SET task_type = ?, description = ?, date = ?, time = ?, duration = ? WHERE id = ?',
      [task_type, description, date, time, duration, taskId],
      function(err) {
        if (err) reject(err);
        resolve(this.changes);
      }
    );
  });
}

async function deleteTask(taskId) {
  return new Promise((resolve, reject) => {
    db.run('DELETE FROM tasks WHERE id = ?', [taskId], function(err) {
      if (err) reject(err);
      resolve(this.changes);
    });
  });
}

async function addUser(name) {
  return new Promise((resolve, reject) => {
    db.run('INSERT INTO users (name) VALUES (?)', [name], function(err) {
      if (err) reject(err);
      resolve(this.lastID);
    });
  });
}

async function getUsers() {
  return new Promise((resolve, reject) => {
    db.all('SELECT * FROM users', (err, rows) => {
      if (err) reject(err);
      resolve(rows);
    });
  });
}

module.exports = {
  initializeDatabase,
  addTask,
  getTasks,
  updateTask,
  deleteTask,
  addUser,
  getUsers
};

This SQLite database setup includes the following features:

1. Database initialization and table creation
2. CRUD operations for tasks (Create, Read, Update, Delete)
3. User management (Add and Get users)
4. Filtered task retrieval based on user, task type, and date range

To use this database in your React application, you'll need to set up a backend server (e.g., using Express.js) that can interact with the SQLite database and expose API endpoints for your frontend to consume.

Here's a brief explanation of the main functions:

• initializeDatabase(): Opens the database connection and creates the necessary tables.
• addTask(task): Adds a new task to the database.
• getTasks(filters): Retrieves tasks from the database, with optional filtering.
• updateTask(taskId, updates): Updates an existing task.
• deleteTask(taskId): Deletes a task from the database.
• addUser(name): Adds a new user to the database.
• getUsers(): Retrieves all users from the database.

To integrate this with your React frontend, you'll need to:

1. Set up an Express.js server that uses these database functions.
2. Create API endpoints that correspond to these database operations.
3. Use a library like axios in your React components to make HTTP requests to these API endpoints.

Would you like me to help you set up the Express.js server next, or would you prefer to focus on another part of the application?

Setup the express.js server and API endpoints next

Certainly! I'll set up an Express.js server with API endpoints that utilize the SQLite database functions we've created. This will allow your React frontend to interact with the database through HTTP requests.

const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');
const {
  initializeDatabase,
  addTask,
  getTasks,
  updateTask,
  deleteTask,
  addUser,
  getUsers
} = require('./database');

const app = express();
const port = process.env.PORT || 3001;

app.use(cors());
app.use(bodyParser.json());

// Initialize database
initializeDatabase();

// Task routes
app.post('/api/tasks', async (req, res) => {
  try {
    const taskId = await addTask(req.body);
    res.status(201).json({ id: taskId, ...req.body });
  } catch (error) {
    res.status(500).json({ error: 'Error adding task' });
  }
});

app.get('/api/tasks', async (req, res) => {
  try {
    const filters = {
      user_id: req.query.user_id,
      task_type: req.query.task_type,
      start_date: req.query.start_date,
      end_date: req.query.end_date
    };
    const tasks = await getTasks(filters);
    res.json(tasks);
  } catch (error) {
    res.status(500).json({ error: 'Error fetching tasks' });
  }
});

app.put('/api/tasks/:id', async (req, res) => {
  try {
    const taskId = parseInt(req.params.id);
    const changes = await updateTask(taskId, req.body);
    if (changes > 0) {
      res.json({ id: taskId, ...req.body });
    } else {
      res.status(404).json({ error: 'Task not found' });
    }
  } catch (error) {
    res.status(500).json({ error: 'Error updating task' });
  }
});

app.delete('/api/tasks/:id', async (req, res) => {
  try {
    const taskId = parseInt(req.params.id);
    const changes = await deleteTask(taskId);
    if (changes > 0) {
      res.json({ message: 'Task deleted successfully' });
    } else {
      res.status(404).json({ error: 'Task not found' });
    }
  } catch (error) {
    res.status(500).json({ error: 'Error deleting task' });
  }
});

// User routes
app.post('/api/users', async (req, res) => {
  try {
    const userId = await addUser(req.body.name);
    res.status(201).json({ id: userId, name: req.body.name });
  } catch (error) {
    res.status(500).json({ error: 'Error adding user' });
  }
});

app.get('/api/users', async (req, res) => {
  try {
    const users = await getUsers();
    res.json(users);
  } catch (error) {
    res.status(500).json({ error: 'Error fetching users' });
  }
});

app.listen(port, () => {
  console.log(`Server running on port ${port}`);
});

This Express.js server sets up the following API endpoints:

1. Tasks:

   • POST /api/tasks: Add a new task
   • GET /api/tasks: Retrieve tasks (with optional filtering)
   • PUT /api/tasks/:id: Update an existing task
   • DELETE /api/tasks/:id: Delete a task

2. Users:

   • POST /api/users: Add a new user
   • GET /api/users: Retrieve all users

The server uses CORS to allow cross-origin requests from your React frontend and body-parser to parse JSON request bodies.

To use this server:

1. Install the required dependencies:

   npm install express cors body-parser
   

2. Save the code in a file named server.js in your project directory.

3. Start the server by running:

   node server.js
   

Now, you'll need to update your React frontend to use these API endpoints. Here's an example of how you can modify the App.js component to fetch tasks from the server:

import React, { useState, useEffect } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import axios from 'axios';
import Calendar from './components/Calendar';
import DayView from './components/DayView';
import Analysis from './components/Analysis';
import NewTaskButton from './components/NewTaskButton';

const API_BASE_URL = 'http://localhost:3001/api';

const App = () => {
  const [tasks, setTasks] = useState([]);
  const [users, setUsers] = useState([]);
  const [taskTypes, setTaskTypes] = useState([
    'Empty dishwasher',
    'Fill dishwasher',
    'Fill laundry',
    'Fold laundry',
    'Cook meal'
  ]);

  useEffect(() => {
    fetchTasks();
    fetchUsers();
  }, []);

  const fetchTasks = async () => {
    try {
      const response = await axios.get(`${API_BASE_URL}/tasks`);
      setTasks(response.data);
    } catch (error) {
      console.error('Error fetching tasks:', error);
    }
  };

  const fetchUsers = async () => {
    try {
      const response = await axios.get(`${API_BASE_URL}/users`);
      setUsers(response.data);
    } catch (error) {
      console.error('Error fetching users:', error);
    }
  };

  const handleAddTask = async (newTask) => {
    try {
      const response = await axios.post(`${API_BASE_URL}/tasks`, newTask);
      setTasks([...tasks, response.data]);
    } catch (error) {
      console.error('Error adding task:', error);
    }
  };

  const handleUpdateTask = async (updatedTask) => {
    try {
      const response = await axios.put(`${API_BASE_URL}/tasks/${updatedTask.id}`, updatedTask);
      setTasks(tasks.map(task => task.id === updatedTask.id ? response.data : task));
    } catch (error) {
      console.error('Error updating task:', error);
    }
  };

  return (
    <Router>
      <div className="app">
        <Switch>
          <Route exact path="/" component={() => <Calendar tasks={tasks} />} />
          <Route path="/day/:date" component={({ match }) => (
            <DayView
              date={match.params.date}
              tasks={tasks.filter(task => task.date === match.params.date)}
              onUpdateTask={handleUpdateTask}
            />
          )} />
          <Route path="/analysis" component={() => <Analysis tasks={tasks} />} />
        </Switch>
        <NewTaskButton onAddTask={handleAddTask} taskTypes={taskTypes} users={users} />
      </div>
    </Router>
  );
};

export default App;

This updated App component now uses axios to make HTTP requests to your Express.js server. It fetches tasks and users when the component mounts, and provides functions to add and update tasks.

To use this updated component:

1. Install axios in your React project:

   npm install axios
   

2. Update your App.js file with this new code.

3. Make sure your Express.js server is running on http://localhost:3001 (or update the API_BASE_URL constant if it's running on a different port or host).

Next steps:

1. Implement the DayView component to display and edit tasks for a specific day.
2. Create the NewTaskButton component for adding new tasks.
3. Develop the Analysis component for task filtering and analysis.

Which part would you like me to focus on next?

Develop the Analysis component

Certainly! I'll develop the Analysis component for task filtering and analysis. This component will allow users to filter tasks based on user, task type, and date range, and will display a summary of task counts and time spent.

import React, { useState, useEffect } from 'react';
import axios from 'axios';
import { format, parseISO } from 'date-fns';
import { LineChart, Line, XAxis, YAxis, CartesianGrid, Tooltip, Legend, ResponsiveContainer } from 'recharts';

const API_BASE_URL = 'http://localhost:3001/api';

const Analysis = () => {
  const [tasks, setTasks] = useState([]);
  const [users, setUsers] = useState([]);
  const [taskTypes, setTaskTypes] = useState([]);
  const [filters, setFilters] = useState({
    user_id: '',
    task_type: '',
    start_date: format(new Date().setDate(1), 'yyyy-MM-dd'), // First day of current month
    end_date: format(new Date(), 'yyyy-MM-dd'), // Today
  });

  useEffect(() => {
    fetchUsers();
    fetchTaskTypes();
    fetchTasks();
  }, []);

  useEffect(() => {
    fetchTasks();
  }, [filters]);

  const fetchUsers = async () => {
    try {
      const response = await axios.get(`${API_BASE_URL}/users`);

export default Analysis;

This Analysis component includes the following features:

1. Filters for user, task type, and date range
2. A summary of total tasks and time spent
3. A breakdown of tasks by type
4. A line chart showing the trend of task count and total time over the selected date range

To use this component, you'll need to install the required dependencies:

npm install date-fns recharts

Here's a brief explanation of the main parts of this component:

• useEffect hooks fetch users, task types, and tasks when the component mounts and when filters change.
• handleFilterChange updates the filters state when the user modifies the filter inputs.
• getTaskSummary calculates the summary statistics from the filtered tasks.
• getChartData prepares the data for the line chart, aggregating tasks by date.
• The render method includes filter inputs, a summary section, and a line chart.

To integrate this component into your app:

1. Add it to your App.js file's imports:

   import Analysis from './components/Analysis';

2. Update the Route for the Analysis page in your App.js:

   <Route path="/analysis" component={Analysis} />

3. Add a link to the Analysis page in your navigation menu (if you have one).

To style this component, you might want to add some CSS. Here's a basic CSS structure to get you started:

.analysis {
  max-width: 800px;
  margin: 0 auto;
  padding: 20px;
}

.filters {
  display: flex;
  justify-content: space-between;
  margin-bottom: 20px;
}

.filters select,
.filters input {
  padding: 5px;
  margin-right: 10px;
}

.summary {
  background-color: #f0f0f0;
  padding: 15px;
  border-radius: 5px;
  margin-bottom: 20px;
}

.summary h3,
.summary h4 {
  margin-top: 0;
}

.summary ul {
  padding-left: 20px;
}

.chart {
  background-color: #ffffff;
  padding: 15px;
  border-radius: 5px;
  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
}

@media (max-width: 600px) {
  .filters {
    flex-direction: column;
  }

  .filters select,
  .filters input {
    width: 100%;
    margin-bottom: 10px;
  }
}

You can add this CSS to your project's stylesheet or use a CSS-in-JS solution like styled-components.

This completes the Analysis component for your Task Tracker app. It provides a comprehensive view of task data with filtering capabilities and visual representation through charts.

Is there anything specific you'd like me to explain further or any other component you'd like me to work on next?

Implement the dayview component

Certainly! I'll implement the DayView component, which will display and allow editing of tasks for a specific day. This component will show tasks in an hourly schedule and provide functionality to update existing tasks.

import React, { useState, useEffect } from 'react';
import axios from 'axios';
import { format, parseISO, addHours, startOfDay, endOfDay } from 'date-fns';

const API_BASE_URL = 'http://localhost:3001/api';

const DayView = ({ date, tasks, onUpdateTask }) => {

  const [editingTask, setEditingTask] = useState(null);
  const [users, setUsers] = useState([]);
  const [taskTypes, setTaskTypes] = useState([]);

  useEffect(() => {
    fetchUsers();
    fetchTaskTypes();
    organizeTasksByHour();
  }, [tasks]);

  const fetchUsers = async () => {

  const organizeTasksByHour = () => {

    const hourlyTasksArray = Array(24).fill().map((_, index) => ({
      hour: format(addHours(dayStart, index), 'HH:mm'),
      tasks: []
    }));

    tasks.forEach(task => {
      const taskHour = parseISO(task.date + 'T' + task.time).getHours();
      hourlyTasksArray[taskHour].tasks.push(task);
    });

    setHourlyTasks(hourlyTasksArray);
  };

  const handleEditClick = (task) => {
    setEditingTask({ ...task });
  };

  const handleEditChange = (e) => {
    const { name, value } = e.target;
    setEditingTask(prev => ({ ...prev, [name]: value }));
  };

  const handleEditSubmit = async (e) => {
    e.preventDefault();
    try {
      await onUpdateTask(editingTask);
      setEditingTask(null);

          </div>
        ))}
      </div>
    </div>
  );
};

export default DayView;

This DayView component includes the following features:

1. Displays tasks organized by hour for the selected day
2. Allows editing of existing tasks
3. Shows task details including type, description, duration, and assigned user
4. Fetches and displays up-to-date user and task type information

To use this component, make sure you have the required dependencies installed:

npm install date-fns

Here's a brief explanation of the main parts of this component:

• useEffect hook organizes tasks by hour when the component mounts or when tasks change
• organizeTasksByHour function creates an array of 24 hour slots and assigns tasks to their respective hours
• handleEditClick, handleEditChange, and handleEditSubmit manage the task editing functionality
• The render method displays an hourly schedule with tasks and provides an edit form when a task is being edited

To integrate this component into your app:

1. Update the import in your App.js file:

   import DayView from './components/DayView';

2. Make sure the Route for the DayView in your App.js is passing the necessary props:

   <Route 
     path="/day/:date" 
     render={({ match }) => (
       <DayView
         date={match.params.date}
         tasks={tasks.filter(task => task.date === match.params.date)}
         onUpdateTask={handleUpdateTask}
       />
     )} 
   />

To style this component, you might want to add some CSS. Here's a basic CSS structure to get you started:

.day-view {
  max-width: 800px;
  margin: 0 auto;
  padding: 20px;
}

.hourly-schedule {
  display: flex;
  flex-direction: column;
}

.hour-slot {
  display: flex;
  border-bottom: 1px solid #e0e0e0;
  min-height: 60px;
}

.hour-label {
  width: 60px;
  padding: 10px;
  font-weight: bold;
  border-right: 1px solid #e0e0e0;
}

.hour-tasks {
  flex-grow: 1;
  padding: 10px;
}

.task-item {
  background-color: #f0f0f0;
  border-radius: 5px;
  padding: 10px;
  margin-bottom: 10px;
}

.task-item form {
  display: flex;
  flex-direction: column;
}

.task-item form input,
.task-item form select {
  margin-bottom: 10px;
  padding: 5px;
}

.task-item form button {
  margin-right: 10px;
}

@media (max-width: 600px) {
  .hour-slot {
    flex-direction: column;
  }

  .hour-label {
    width: 100%;
    border-right: none;
    border-bottom: 1px solid #e0e0e0;
  }
}

You can add this CSS to your project's stylesheet or use a CSS-in-JS solution like styled-components.

This completes the DayView component for your Task Tracker app. It provides a detailed view of tasks for a specific day, organized by hour, and allows for easy editing of existing tasks.

Is there anything specific you'd like me to explain further or any other component you'd like me to work on next?

Create the newtaskbutton component

Certainly! I'll create the NewTaskButton component, which will be a floating action button that allows users to add a new task. This component will open a form when clicked, allowing users to input details for a new task.

import React, { useState, useEffect } from 'react';
import axios from 'axios';
import { format } from 'date-fns';

const API_BASE_URL = 'http://localhost:3001/api';

const NewTaskButton = ({ onAddTask }) => {
  const [isFormOpen, setIsFormOpen] = useState(false);
  const [newTask, setNewTask] = useState({
    user_id: '',
    task_type: '',
    description: '',
    date: format(new Date(), 'yyyy-MM-dd'),
    time: format(new Date(), 'HH:mm'),
    duration: 30
  });
  const [users, setUsers] = useState([]);
  const [taskTypes, setTaskTypes] = useState([]);

  useEffect(() => {
    fetchUsers();
    fetchTaskTypes();
  }, []);

  const fetchUsers = async () => {
    try {
      const response = await axios.get(`${API_BASE_URL}/users`);
      setUsers(response.data);
    } catch (error) {
      console.error('Error fetching users:', error);
    }
  };

  const fetchTaskTypes = async () => {
    try {
      const response = await axios.get(`${API_BASE_URL}/tasks`);
      const types = [...new Set(response.data.map(task => task.task_type))];
      setTaskTypes(types);
    } catch (error) {
      console.error('Error fetching task types:', error);
    }
  };

  const handleInputChange = (e) => {
    const { name, value } = e.target;
    setNewTask(prevTask => ({ ...prevTask, [name]: value }));
  };

  const handleSubmit = async (e) => {
    e.preventDefault();

        time: format(new Date(), 'HH:mm'),
        duration: 30
      });
    } catch (error) {
      console.error('Error adding new task:', error);
    }
  };

  const handleNewTaskType = () => {
    const newType = prompt('Enter new task type:');
    if (newType && !taskTypes.includes(newType)) {
      setTaskTypes([...taskTypes, newType]);
      setNewTask(prevTask => ({ ...prevTask, task_type: newType }));
    }
  };

  const handleNewUser = () => {
    const newUser = prompt('Enter new user name:');
    if (newUser) {
      axios.post(`${API_BASE_URL}/users`, { name: newUser })
        .then(response => {
          setUsers([...users, response.data]);
          setNewTask(prevTask => ({ ...prevTask, user_id: response.data.id }));
        })
        .catch(error => console.error('Error adding new user:', error));
    }
  };

  return (

This NewTaskButton component includes the following features:

1. A floating action button that opens a form when clicked
2. A form for adding new tasks with fields for user, task type, description, date, time, and duration
3. The ability to add new users and task types on the fly
4. Fetches existing users and task types from the API

To use this component, make sure you have the required dependencies installed:

npm install date-fns axios

Here's a brief explanation of the main parts of this component:

• useState hooks manage the form's open/close state and the new task data
• useEffect hook fetches users and task types when the component mounts
• handleInputChange updates the new task state as the user fills out the form
• handleSubmit sends the new task data to the parent component for processing
• handleNewTaskType and handleNewUser allow adding new task types and users respectively

To integrate this component into your app:

1. Update the import in your App.js file:

   import NewTaskButton from './components/NewTaskButton';

2. Add the NewTaskButton component to your App's render method:

   <NewTaskButton onAddTask={handleAddTask} />

To style this component, you might want to add some CSS. Here's a basic CSS structure to get you started:

.new-task-button {
  position: fixed;
  bottom: 20px;
  right: 20px;
  z-index: 1000;
}

.floating-button {
  width: 60px;
  height: 60px;
  border-radius: 50%;
  background-color: #007bff;
  color: white;
  font-size: 24px;
  border: none;
  cursor: pointer;
  box-shadow: 0 2px 5px rgba(0, 0, 0, 0.2);
  transition: background-color 0.3s ease;
}

.floating-button:hover {
  background-color: #0056b3;
}

.new-task-form {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  background-color: white;
  padding: 20px;
  border-radius: 5px;
  box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);
  max-width: 400px;
  width: 100%;
}

.new-task-form h3 {
  margin-top: 0;
}

.new-task-form form {
  display: flex;
  flex-direction: column;
}

.new-task-form input,
.new-task-form select {
  margin-bottom: 10px;
  padding: 5px;
}

.new-task-form button {
  margin-top: 10px;
  padding: 10px;
  background-color: #007bff;
  color: white;
  border: none;
  cursor: pointer;
  transition: background-color 0.3s ease;
}

.new-task-form button:hover {
  background-color: #0056b3;
}

.new-task-form button[type="button"] {
  background-color: #6c757d;
}

.new-task-form button[type="button"]:hover {
  background-color: #545b62;
}

@media (max-width: 600px) {
  .new-task-form {
    width: 90%;
  }
}

You can add this CSS to your project's stylesheet or use a CSS-in-JS solution like styled-components.

This completes the NewTaskButton component for your Task Tracker app. It provides a user-friendly way to add new tasks, including the ability to add new users and task types on the fly.

Is there anything specific you'd like me to explain further or any other component you'd like me to work on next?
