create website to analyse my matlab code in javascript

index.tsx
// 1. Set up a Node.js server with Express.js installed
const express = require('express');
const app = express();
const port = 3000;

// 2. Create a form on your website where users can upload their Matlab code files
app.get('/', (req, res) => {
  res.send(`
    <form action="/uploadMatlab" method="POST" enctype="multipart/form-data">
      <input type="file" name="matlabCode">
      <button type="submit">Submit</button>
    </form>
  `);
});

// 3. Using a library such as "matlab-node", run the user's uploaded Matlab code on the server and convert the output to a JSON object
const { execute } = require('matlab-node');
const fileUpload = require('express-fileupload');
app.use(fileUpload());

app.post('/uploadMatlab', (req, res) => {
  const matlabCode = req.files.matlabCode.data.toString('utf8');
  execute(matlabCode, (err, result) => {
    if (err) {
      res.send('Error occurred running Matlab code');
    } else {
      const outputJSON = result.value;
      // 4. Create a view on your website to display the JSON object in a readable format
      res.send(`<pre>${JSON.stringify(outputJSON, null, 2)}</pre>`);
    }
  });
});

// 5. Allow users to interact with the JSON object by adding filters or other features to the view

app.listen(port, () => {
  console.log(`App listening at http://localhost:${port}`);
});
