re: Hello K, great post learned a lot I didnt know this was possible using fetch. Just one quick question. How would you manage if you wanted to fetch ...
 

Glad you liked it.

I'd use React hooks.

function MyComponent(props) {
  const [info, setInfo] = React.useState("");
  const [remoteData, setRemoteData] = React.useState(
    "No data fetched yet!"
  );

  async function load() {
    const response = await fetch(
      "http://example.com?info=" + info
    );
    const text = await response.text();
    setRemoteData(text);
  }

  return (
    <div>
      <input
        value={info}
        onChange={(e) => setInfo(e.target.value)}
      />
      <button onClick={load}>Fetch</button>
      <textarea>{remoteData}</textarea>
    </div>
  );
}
 

That is great I think that might works thanks a lot! I'm just trying to figure out this error:
Access to fetch at 'MyUrl' from origin 'localhost:8100' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's. I've found to fix it adding {mode:"no-cors"} in the fetch call but the object returns null. Do you know anything about this kind of error?
