Step-by-Step Guide: Building a Simple Todo App

Prerequisites:

• A Supabase account: https://supabase.com
• Basic knowledge of JavaScript and HTML

1. Create a Supabase Project:

• Sign in to your Supabase account.
• Click on "New project" and choose a name for your project.

2. Set Up Authentication:

• Navigate to the "Authentication" section in your Supabase dashboard.
• Enable email/password authentication.

3. Create a Database Table:

• Go to the "Database" section and create a new table named "todos".
• Add the following columns:
  • id (integer, primary key)
  • task (text)
  • completed (boolean)

4. Install Supabase SDK:

• Use npm or yarn to install the Supabase JavaScript SDK:

npm install @supabase/supabase-js

5. Create a Frontend App:

• Create a new HTML file (index.html) and add the following code:

<!DOCTYPE html>
<html>
 <head>
  <title>
   Todo App
  </title>
  <script src="https://cdn.jsdelivr.net/npm/@supabase/supabase-js">
  </script>
  <script src="script.js">
  </script>
 </head>
 <body>
  <h1>
   Todo App
  </h1>
  <input id="taskInput" placeholder="Enter task..." type="text"/>
  <button id="addTaskButton">
   Add Task
  </button>
  <ul id="todoList">
  </ul>
 </body>
</html>

6. Implement Functionality in script.js:

const supabaseUrl = 'your-supabase-url'; // Replace with your Supabase URL
const supabaseKey = 'your-supabase-key'; // Replace with your Supabase key
const supabase = createClient(supabaseUrl, supabaseKey);

const taskInput = document.getElementById('taskInput');
const addTaskButton = document.getElementById('addTaskButton');
const todoList = document.getElementById('todoList');

addTaskButton.addEventListener('click', async () => {
  const task = taskInput.value;
  if (task.trim() !== '') {
    try {
      const { data, error } = await supabase
        .from('todos')
        .insert([{ task, completed: false }]);

      if (error) {
        console.error(error);
        return;
      }

      renderTodos();
    } catch (error) {
      console.error(error);
    }
  }
});

function renderTodos() {
  const { data, error } = supabase
    .from('todos')
    .select('*');

  if (error) {
    console.error(error);
    return;
  }

  todoList.innerHTML = ''; // Clear previous items
  data.forEach(todo => {
    const li = document.createElement('li');
    li.textContent = todo.task;
    todoList.appendChild(li);
  });
}

renderTodos(); // Initial rendering

7. Run the App:

• Open index.html in your web browser.

Challenges and Limitations

1. Complexity for Large-Scale Applications: While Supabase is powerful, it may not be the best choice for highly complex applications with extensive backend logic.
2. Limited Customization: Although Supabase offers a high level of functionality, it may require some workarounds or custom code to achieve specific requirements.
3. Dependency on Supabase Infrastructure: Applications built with Supabase are dependent on Supabase's infrastructure, which could potentially lead to downtime or performance issues.

Comparison with Alternatives

1. Firebase: Firebase is a popular BaaS platform offered by Google. It offers similar features to Supabase but is a proprietary platform.
2. AWS Amplify: Amazon's Amplify provides a wide range of services, including backend infrastructure, authentication, and storage. It is a mature and robust platform, but it can be more complex and expensive than Supabase.
3. Netlify: Netlify is a platform for hosting web applications. While it offers some backend features, it is primarily focused on front-end development.
