Todo List API
Create a RESTful API for a todo list application. This project will cover many fundamental aspects of backend development:
- Setting up a server (using Express.js with Node.js, for example)
- Implementing CRUD operations (Create, Read, Update, Delete)
- Working with a database (start with SQLite for simplicity)
- Handling user authentication
- Implementing basic security measures
Here’s a basic structure to get you started:
const express = require('express');
const sqlite3 = require('sqlite3').verbose();
const app = express();
const port = 3000;
// Middleware
app.use(express.json());
// Database connection
const db = new sqlite3.Database('./todos.db');
// Create todos table
db.run(`CREATE TABLE IF NOT EXISTS todos (
id INTEGER PRIMARY KEY AUTOINCREMENT,
title TEXT,
completed BOOLEAN
)`);
// Routes
app.get('/todos', (req, res) => {
db.all("SELECT * FROM todos", [], (err, rows) => {
if (err) {
res.status(500).json({error: err.message});
return;
}
res.json(rows);
});
});
app.post('/todos', (req, res) => {
const {title} = req.body;
db.run(`INSERT INTO todos (title, completed) VALUES (?, ?)`, [title, false], function(err) {
if (err) {
res.status(500).json({error: err.message});
return;
}
res.json({id: this.lastID, title, completed: false});
});
});
// Add more routes for updating and deleting todos
app.listen(port, () => {
console.log(`Todo list API running on port ${port}`);
});This basic structure sets up a simple API with endpoints to get all todos and create a new todo. You can expand on this by adding update and delete functionality, implementing user authentication, and enhancing security measures.
