How to build Project management tool with Lovable?

Setting Up Your Lovable Project

Log in to your Lovable account and click on the button to create a new project.
When prompted, choose a blank project. You will be presented with a file explorer and a code editor.
In the file explorer, create the following new files: index.html, style.css, and script.js. These files will form the core of your project management tool.

Adding Dependencies for Project Management

Lovable does not have a terminal, so dependencies need to be added directly in your code. We will include the Project Manager Library via a CDN link.

Open your index.html file and add the following snippet inside the <head> section. This ensures that the library is loaded when your project starts.


<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Project Management Tool</title>
  <link rel="stylesheet" href="style.css">
  <!-- Include Project Manager Library dependency -->
  <script src="https://cdn.example.com/project-manager-lib.js"></script>
</head>

This library will help handle task creation, updates, and state management in your project.

Creating the Core Files

In your index.html file, set up the basic HTML skeleton and structure for your project management tool. Paste the following code snippet into index.html:




  
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Project Management Tool</title>
    <link rel="stylesheet" href="style.css">
    <script src="https://cdn.example.com/project-manager-lib.js"></script>
  
  
    <div id="app">
      <h1>My Project Manager</h1>
      <div id="new-task">
        <input type="text" id="task-input" placeholder="Enter new task..." />
        <button id="add-task">Add Task</button>
      </div>
      <div id="task-list">
        <!-- Task items will be rendered here -->
      </div>
    </div>
    <script src="script.js"></script>

Create a style.css file for styling your project. This file will control the look and feel of your tool.
Create a script.js file where you will implement the task management logic using JavaScript.

Building the User Interface

Edit your style.css file to style the project management tool. Paste the following into style.css:


body {
  font-family: Arial, sans-serif;
  background: #f7f7f7;
  margin: 0;
  padding: 20px;
}

#app {
  max-width: 600px;
  margin: auto;
  background: #fff;
  padding: 20px;
  border-radius: 5px;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}
#new-task {
  display: flex;
  margin-bottom: 20px;
}
#task-input {
  flex: 1;
  padding: 10px;
  border: 1px solid #ddd;
  border-radius: 3px;
}
#add-task {
  padding: 10px 20px;
  border: none;
  background: #28a745;
  color: #fff;
  margin-left: 10px;
  border-radius: 3px;
  cursor: pointer;
}
.task {
  padding: 10px;
  border-bottom: 1px solid #eee;
  display: flex;
  justify-content: space-between;
  align-items: center;
}
.task.done {
  text-decoration: line-through;
  color: #888;
}
.task button {
  background: #dc3545;
  border: none;
  color: #fff;
  padding: 5px 10px;
  border-radius: 3px;
  cursor: pointer;
}

This CSS adds basic styling for the layout, input, button elements, and for marking tasks as done.

Implementing Task Management Logic

Open your script.js file to add the JavaScript needed for creating, marking, and deleting tasks. Insert the following code:


// Array to store tasks
let tasks = [];

// Function to render tasks
function renderTasks() {
  const taskList = document.getElementById('task-list');
  taskList.innerHTML = ''; // Clear previous content
  tasks.forEach((task, index) => {
    const taskEl = document.createElement('div');
    taskEl.className = 'task' + (task.done ? ' done' : '');
    taskEl.innerHTML = `
      ${task.text}
      

        
        
      

    `;
    taskList.appendChild(taskEl);
  });
}
// Function to add a task
function addTask() {
  const taskInput = document.getElementById('task-input');
  const text = taskInput.value.trim();
  if (text) {
    tasks.push({ text: text, done: false });
    taskInput.value = '';
    renderTasks();
  }
}
// Function to toggle task completion
function toggleTask(index) {
  tasks[index].done = !tasks[index].done;
  renderTasks();
}
// Function to delete a task
function deleteTask(index) {
  tasks.splice(index, 1);
  renderTasks();
}
// Event listener for add button
document.getElementById('add-task').addEventListener('click', addTask);

This code uses a basic array to store tasks and provides functions to add, toggle (mark as done/undone), and delete tasks. Each change updates the display by re-rendering the task list.

Testing and Debugging Your Application

Once you have added all the code, use Lovable’s built-in preview feature to run your project.
In the preview pane, you should see your Project Management Tool interface. Try adding tasks using the input field and buttons.
If the tasks do not appear or buttons do not work as expected, double-check that each code snippet is placed in the correct file and that you have saved your changes.
Use Lovable’s console (if available) to view any error messages and make necessary adjustments to your code.

How to update a task's status and recalculate project progress with Lovable


const express = require('express');
const router = express.Router();
const mongoose = require('mongoose');

// Define Task and Project Schemas
const TaskSchema = new mongoose.Schema({
  title: String,
  description: String,
  status: { type: String, enum: ['pending', 'in-progress', 'completed'], default: 'pending' },
  project: { type: mongoose.Schema.Types.ObjectId, ref: 'Project' },
  dependencies: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Task' }]
});

const ProjectSchema = new mongoose.Schema({
  name: String,
  description: String,
  progress: { type: Number, default: 0 },
  tasks: [{ type: mongoose.Schema.Types.ObjectId, ref: 'Task' }]
});

const Task = mongoose.model('Task', TaskSchema);
const Project = mongoose.model('Project', ProjectSchema);

// Endpoint: Update Task Status and Recalculate Project Progress
router.put('/projects/:projectId/tasks/:taskId/status', async (req, res) => {
  try {
    const { status } = req.body;
    const { projectId, taskId } = req.params;
    
    // Update task status
    const task = await Task.findOneAndUpdate(
      { \_id: taskId, project: projectId },
      { status },
      { new: true }
    );
    if (!task) {
      return res.status(404).json({ error: 'Task not found in the given project' });
    }

    // Recalculate project progress based on tasks completion ratio
    await recalcProjectProgress(projectId);
    res.json({ message: 'Task status updated', task });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

// Helper function: recalc project progress
async function recalcProjectProgress(projectId) {
  const tasks = await Task.find({ project: projectId });
  const totalTasks = tasks.length;
  if (totalTasks === 0) return;

  const completedTasks = tasks.filter(task => task.status === 'completed').length;
  const progress = Math.round((completedTasks / totalTasks) \* 100);

  await Project.findByIdAndUpdate(projectId, { progress });
}

module.exports = router;

How to Generate a Dependency-Based Task Schedule in Your Project Management Tool


const express = require('express');
const router = express.Router();
const Task = require('./models/task');     // Mongoose model for Task
const Project = require('./models/project'); // Mongoose model for Project

// Helper: Topological sort to determine task scheduling order based on dependencies
async function topologicalSort(projectId) {
  const tasks = await Task.find({ project: projectId }).lean();
  const graph = new Map();
  const inDegree = new Map();

  tasks.forEach(task => {
    const id = task.\_id.toString();
    graph.set(id, []);
    inDegree.set(id, 0);
  });

  tasks.forEach(task => {
    const id = task.\_id.toString();
    task.dependencies.forEach(dep => {
      const depId = dep.toString();
      if (graph.has(depId)) {
        graph.get(depId).push(id);
        inDegree.set(id, inDegree.get(id) + 1);
      }
    });
  });

  const queue = [];
  inDegree.forEach((deg, id) => {
    if (deg === 0) queue.push(id);
  });

  const sorted = [];
  while (queue.length) {
    const current = queue.shift();
    sorted.push(current);
    graph.get(current).forEach(neighbor => {
      inDegree.set(neighbor, inDegree.get(neighbor) - 1);
      if (inDegree.get(neighbor) === 0) queue.push(neighbor);
    });
  }

  if (sorted.length !== tasks.length) {
    throw new Error('Cycle detected in task dependencies');
  }
  return sorted;
}

// Endpoint: Generate a task schedule based on dependency resolution
router.get('/projects/:projectId/generate-schedule', async (req, res) => {
  try {
    const { projectId } = req.params;
    const project = await Project.findById(projectId);
    if (!project) {
      return res.status(404).json({ error: 'Project not found' });
    }

    const sortedTaskIds = await topologicalSort(projectId);
    
    // Assign a start date for each task incremented by one day from current date
    let currentDate = new Date();
    const schedule = {};
    for (const taskId of sortedTaskIds) {
      schedule[taskId] = currentDate.toISOString().split('T')[0];
      currentDate.setDate(currentDate.getDate() + 1);
    }
    
    res.json({ project: project.name, schedule });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

module.exports = router;

Best Practices for Building a Project management tool with AI Code Generators

Understanding Your Requirements and Planning

Identify the core functionalities your project management tool must have, such as task tracking, team collaboration, progress dashboards, notifications, and reporting.
Determine how AI will enhance the tool. For example, using AI code generators to automate repetitive coding tasks, generate optimized templates for new modules, or provide code suggestions during development.
Gather input from potential users regarding their needs in project management and establish clear objectives for your project.

Choosing the Right Technology Stack

Select a backend language (such as Python, Node.js, or Ruby) and corresponding web frameworks that suit your project requirements.
Pick a frontend framework (like React, Vue, or Angular) that is beginner-friendly and suitable for interactive, dynamic interfaces.
Determine which AI code generator or assistant tool you will integrate (e.g., OpenAI Codex, GitHub Copilot, or similar service) to assist with code generation and suggestions.

Designing the Architecture and UI/UX

Map out the overall architecture with components for user management, task modules, data storage, and AI integration.
Create simple wireframes or sketches of how the user interface should appear, focusing on ease of navigation and clarity of information.
Ensure your design supports scalability, so new features driven by AI-generated code can be added without major overhauls.

Setting Up Your Development Environment

Install necessary software such as code editors (for instance, Visual Studio Code) and set up version control using Git.
Create a new project repository on platforms like GitHub or GitLab for collaborative development and version tracking.
Integrate your chosen AI code generator into your development environment. Many modern IDEs support extensions for AI tools. Follow your tool’s documentation to enable this feature.

Integrating AI Code Generators into Your Workflow

Configure the AI tool’s settings in your IDE to ensure it suggests code that matches your project's language and style.

Start by generating boilerplate code for common tasks such as creating a user authentication module or a task management component. For example, here is a snippet to set up a basic server in Node.js:


const express = require('express');
const app = express();
const port = process.env.PORT || 3000;

app.use(express.json());
app.get('/', (req, res) => {
  res.send('Project Management Tool Running');
});
app.listen(port, () => {
  console.log(Server is running on port ${port});
});

Use the AI generator to provide suggestions, optimize code structure, or add comments explaining complex code sections which can be particularly useful if you’re new to programming.

Building Core Features with AI Assistance

Create modules for key functionalities such as task creation, project timelines, team assignments, and progress tracking.

When building a module, ask the AI code generator for help with repetitive patterns like CRUD operations. For example, generating a simple code module in Python with Flask:


from flask import Flask, request, jsonify

app = Flask(name)
tasks = []
@app.route('/tasks', methods=['GET'])
def get_tasks():
    return jsonify(tasks)
@app.route('/tasks', methods=['POST'])
def create_task():
    new_task = request.get_json()
    tasks.append(new_task)
    return jsonify(new_task), 201
if name == 'main':
    app.run(debug=True)

Review and customize the generated code to ensure it adheres to your project's requirements and coding style.

Implementing Quality Assurance and Testing

Set up unit testing and automated testing frameworks (e.g., Jest for JavaScript or PyTest for Python) to test your application's functionalities.
Use the AI code generator to help write detailed test cases by suggesting test scenarios based on the application flow.
Regularly run tests and review code for any potential bugs or security vulnerabilities before deploying changes.

Creating Documentation and Training Materials

Document the architecture, functionalities, and API endpoints of your project management tool. This should include instructions on how to use AI code generator features.
Generate user manuals and step-by-step guides that explain how non-technical users can create and manage projects within the tool.
Use clear language and include screenshots or code snippets (wrapped in <pre><code class="hljs"> blocks) to illustrate procedures.

Deploying Your Application

Decide on a hosting environment (e.g., cloud services like AWS, Heroku, or DigitalOcean) to deploy your application.
Use continuous integration (CI) tools such as GitHub Actions to automate testing and deployment. The AI code generator can help generate scripts for automated deployments. For example, a basic CI script snippet might look like:
```
# 
```
