Introduction

Creating a daily planner is an excellent way to stay organized and manage your time effectively. A planner that displays time slots for each day and allows scheduling tasks/events can be a valuable tool for individuals, teams, and businesses alike. In this article, we will guide you through the process of building a daily planner that meets the acceptance criteria outlined below.

Summary

A daily planner is a digital or physical tool that helps users plan and manage their daily tasks and events. It typically displays a calendar view of the day, allowing users to schedule tasks and events at specific times. The planner should persist data across sessions, ensuring that users can access their scheduled tasks and events even after closing the application.

Goals

The primary goals of building a daily planner are:

Let user add events to specific times: The planner should allow users to create tasks or events with a specific time slot, enabling them to schedule their tasks and events accurately.
Possibly show an hourly or block-based layout: The planner should display a daily view of the tasks and events, with an option to show an hourly or block-based layout, making it easier for users to visualize their schedule.
Persist data across sessions: The planner should store user data, including scheduled tasks and events, persisting it across sessions, ensuring that users can access their data even after closing the application.

Acceptance Criteria

To ensure that the daily planner meets the required functionality, we have outlined the following acceptance criteria:

The user can create tasks/events with a time slot: The planner should allow users to create tasks or events with a specific time slot, enabling them to schedule their tasks and events accurately.
The planner displays tasks in a daily view: The planner should display a daily view of the tasks and events, making it easier for users to visualize their schedule.
Tasks can be edited or removed: The planner should allow users to edit or remove tasks and events, enabling them to make changes to their schedule as needed.

Designing the Planner

To build a daily planner that meets the acceptance criteria, we need to design a user-friendly interface that allows users to create, edit, and remove tasks and events. Here's a possible design for the planner:

Daily View

The daily view should display a calendar view of the day, with time slots for each hour or block. Users should be able to click on a time slot to create a new task or event.

Task Creation

When a user clicks on a time slot, a task creation form should appear, allowing them to enter the task name, description, and start and end times.

Task Editing

Users should be able to edit existing tasks by clicking on the task and editing the task name, description, and start and end times.

Task Removal

Users should be able to remove tasks by clicking on the task and selecting the "Remove" option.

Data Persistence

The planner should store user data, including scheduled tasks and events, persisting it across sessions.

Implementing the Planner

To implement the daily planner, we can use a combination of front-end and back-end technologies. Here's a possible implementation:

Front-end

We can use a front-end framework like React or Angular to build the user interface of the planner. We can use a library like Moment.js to handle date and time calculations.

Back-end

We can use a back-end framework like Node.js or Django to store and retrieve user data. We can use a database like MongoDB or PostgreSQL to store user data.

API

We can create a RESTful API to handle user requests and send responses back to the front-end. We can use a library like Express.js to create the API.

Example Code

Here's an example code snippet in JavaScript to give you an idea of how the planner can be implemented:

// Front-end code
import React, { useState, useEffect } from 'react';
import moment from 'moment';

function DailyPlanner() {
  const [tasks, setTasks] = useState([]);
  const [newTask, setNewTask] = useState({});

  useEffect(() => {
    // Fetch tasks from API
    fetch('/api/tasks')
      .then(response => response.json())
      .then(data => setTasks(data));
  }, []);

  const handleTaskCreation = () => {
    // Create new task
    fetch('/api/tasks', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(newTask),
    })
      .then(response => response.json())
      .then(data => setTasks([...tasks, data]));
  };

  const handleTaskEditing = (task) => {
    // Edit existing task
    fetch(`/api/tasks/${task.id}`, {
      method: 'PUT',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(task),
    })
      .then(response => response.json())
      .then(data => setTasks(tasks.map(t => t.id === task.id ? data : t)));
  };

  const handleTaskRemoval = (task) => {
    // Remove task
    fetch(`/api/tasks/${task.id}`, {
      method: 'DELETE',
    })
      .then(() => setTasks(tasks.filter(t => t.id !== task.id)));
  };

  return (
    <div>
      <h1>Daily Planner</h1>
      <ul>
        {tasks.map((task, index) => (
          <li key={index}>
            <span>{task.name}</span>
            <span>{moment(task.start).format('hh:mm')}</span>
            <span>{moment(task.end).format('hh:mm')}</span>
            <button onClick={() => handleTaskEditing(task)}>Edit</button>
            <button onClick={() => handleTaskRemoval(task)}>Remove</button>
          </li>
        ))}
      </ul>
      <form>
        <input
          type="text"
          value={newTask.name}
          onChange={(e) => setNewTask({ ...newTask, name: e.target.value })}
        />
        <input
          type="datetime-local"
          value={newTask.start}
          onChange={(e) => setNewTask({ ...newTask, start: e.target.value })}
        />
        <input
          type="datetime-local"
          value={newTask.end}
          onChange={(e) => setNewTask({ ...newTask, end: e.target.value })}
        />
        <button onClick={handleTaskCreation}>Create Task</button>
      </form>
    </div>
  );
}

export default DailyPlanner;

Back-end Code

// Back-end code
const express = require('express');
const app = express();
const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/planner', { useNewUrlParser: true, useUnifiedTopology: true });

const taskSchema = new mongoose.Schema({
  name: String,
  start: Date,
  end: Date,
});

const Task = mongoose.model('Task', taskSchema);

app.get('/api/tasks', (req, res) => {
  Task.find().then(tasks => res.json(tasks));
});

app.post('/api/tasks', (req, res) => {
  const task = new Task(req.body);
  task.save().then(() => res.json(task));
});

app.put('/api/tasks/:id', (req, res) => {
  Task.findByIdAndUpdate(req.params.id, req.body, { new: true }).then(task => res.json(task));
});

app.delete('/api/tasks/:id', (req, res) => {
  Task.findByIdAndRemove(req.params.id).then(() => res.json({ message: 'Task removed' }));
});

app.listen(3000, () => {
  console.log('Server listening on port 3000');
});
