            useEffect(() =&gt; {
                fetchTodos();
            }, []);

            const fetchTodos = async () =&gt; {
                try {
                    const response = await axios.get('http://localhost:3000/todos');
                    setTodos(response.data);
                } catch (error) {
                    console.error(error);
                }
            };

            const handleAddTodo = async () =&gt; {
                try {
                    const response = await axios.post('http://localhost:3000/todos', { text: newTodoText });
                    setTodos([...todos, response.data]);
                    setNewTodoText('');
                } catch (error) {
                    console.error(error);
                }
            };

            return (
                <div classname="App">
                    <h1>To-Do List</h1>
                    <ul>
                        {todos.map((todo, index) =&gt; (
                            <li key="{index}">{todo.text}</li>
                        ))}
                    </ul>
                    <input =="" onchange="{(e)" type="text" value="{newTodoText}"/> setNewTodoText(e.target.value)}
                    /&gt;
                    <button onclick="{handleAddTodo}">Add Todo</button>
                </div>
            );
        }

        export default App;
    </code>
