How to import a .txt file from my source?

Not wanting to use fetch as it makes me have to deal with async responses. I solved my problem like this.

1. Created a seperate .js file and assigned my text to a variable
2. Exported the variable

const mytext = `test
 this is multiline text.
 more text`;

export default mytext ;

3. In my other component, I import the file.

import mytext from './mytextfile.js';

4. I am now free to assign it to a variable or use it anywhere in my component.

 const gotTheText = mytext;
 return (<textarea defaultValue={gotTheText}></textarea>);

You should use a json file instead:

sample.json:

{
  "text": "some sample text"
}

component:

import { text } from './sample.json';

console.log(text); // "some sample text"

This works well in practice:

import React from 'react';
import textfile from "../assets/NOTES.txt";

function Notes() {
  const [text, setText] = React.useState();
  fetch(textfile)
    .then((response) => response.text())
    .then((textContent) => {
      setText(textContent);
    });
  return text || "Loading...";
}

I've solved my problem.

  handleClick = () => {

    fetch('/sample.txt')
    .then((r) => r.text())
    .then(text  => {
      console.log(text);
    })  
  }
