HMR not working

[nyck33]

it's supposed to work out of the box right? Why isn't it working?

I changed the name to App.jsx

import React, { useState, useEffect } from 'react';
import axios from 'axios';
import './App.css';

function App() {
  const [file, setFile] = useState(null);
  const [fileName, setFileName] = useState("");
  const [outputDir, setOutputDir] = useState("");
  const [promptFileName, setPromptFileName] = useState("");
  const [outputFile, setOutputFile] = useState("");
  const [tokenLimit, setTokenLimit] = useState(800);
  const [openAiPrompt, setOpenAiPrompt] = useState("");
  const [message, setMessage] = useState("");

  useEffect(() => {
    if (fileName) {
      const fileBaseName = fileName.substring(0, fileName.lastIndexOf('.'));
      setOutputFile(`translated_${fileBaseName}.srt`);
    }
  }, [fileName]);

  const handleFileChange = (e) => {
    const uploadedFile = e.target.files[0];
    if (uploadedFile) {
      setFile(uploadedFile);
      setFileName(uploadedFile.name);

      // Extract directory path and set output directory
      const directory = uploadedFile.webkitRelativePath.split('/').slice(0, -1).join('/');
      const outputDirectory = directory ? `${directory}/chunks` : 'chunks';
      setOutputDir(outputDirectory);
    }
  };

  const handlePromptFileChange = (e) => {
    const promptFile = e.target.files[0];
    if (promptFile) {
      setPromptFileName(promptFile.name);
      // Optionally, read the file content and set it to openAiPrompt
      const reader = new FileReader();
      reader.onload = (event) => {
        setOpenAiPrompt(event.target.result);
      };
      reader.readAsText(promptFile);
    }
  };

  const handleOutputDirChange = (e) => {
    const userInput = e.target.value;
    if (userInput) {
      setOutputDir((prev) => prev.replace(/\/output$/, `/${userInput}`));
    }
  };

  const handleSubmit = async (e) => {
    e.preventDefault();
    if (!file) {
      setMessage("Please upload a file.");
      return;
    }

    const formData = new FormData();
    formData.append("file", file);

    try {
      const uploadResponse = await axios.post("http://localhost:8000/uploadfile/", formData);
      const fileLocation = uploadResponse.data.file_location;

      const request = {
        input_file: fileLocation,
        output_dir: outputDir,
        prompt_file: promptFileName,
        output_file: outputFile,
        token_limit: tokenLimit,
        openai_prompt: openAiPrompt
      };

      const translationResponse = await axios.post("http://localhost:8000/translate/", request);
      setMessage(translationResponse.data.message);
    } catch (error) {
      setMessage(`An error occurred: ${error.response.data.message}`);
    }
  };

  return (
    <div className="App">
      <header className="App-header">
        <h1>OpenAI Translator App</h1>
        <form onSubmit={handleSubmit}>
          <div className="form-group">

  );
}

export default App;
