App Example Using Itusen APIs

Below is an example of a simple web app that uses the Itusen APIs:

      const response = await fetch('/data/items');
      const data = await response.json();
      console.log(data);
    }

    const submitData = async () => {
      const response = await fetch('/data/submit', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({ item: 'value' })
      });
      const result = await response.json();
      console.log(result);
    }

    const signUp = async () => {
      const response = await fetch('/auth/signup', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({ username: 'exampleUser', password: 'securePassword' })
      });
      const result = await response.json();
      console.log(result);
