for example if you need a file in this shape you can place this within a .json file and fetch this from your react project
so how do you fetch this file?

fetch("http://localhost:3000/data/TeaItem.json", {})
      .then((response) => response.json())
      .then((response) => {
        this.setState({ data: response.data });
      });
